Mercedes CLS55 AMG W219, Replacing The Supercharger Idler Pulley

I noticed that the supercharger idler pulley had quite some dirt accumulation on it and also felt a bit of play, so decided to replace it with a new pulley. I made the right decision as the grease was escaping and therefore attracting the dirt.

Runs smooth again with the new pulley. When I will upgrade with billet pulleys, I will also replace the tensioner itself.

Old (+dirty) and new pulley



Mercedes CLS55 AMG W219, Replacing The 4 AMG Exhaust Rubbers

Replaced all 4 exhaust rubbers with OE AMG exhaust rubbers. Each AMG logo adds approximately 1 HP, which is good value for money ๐Ÿ˜›

I bought a special tool to make this easier, and I can highly recommend it! Made replacing them way easier and faster without the need for cutting them up or using flathead screwdrivers etc.

Mercedes CLS55 AMG W219, Solving AirMatic Issues

I was suprised with this look, which is a horror type of situation for every CLS owner with Airmatic suspension. In the end I tracked the issue down to a leaking compressor air line (to the valve body), which solved the issue.




Mercedes CLS55 AMG W219, Leather Maintenance With Sonax Leather Care

After reading a whole bunch of positive reviews on Amazon about the Sonax Leather Care, I bought a bottle and went to work on the almost full leather interior of the CLS55. It worked well, the product was absorbed really fast, that leads me to believe it was really needed (as leather is a natural product).

Will be doing this every few months to get the most out of the interior!




Mercedes CLS55 AMG W219, Replacing The Power Steering Reservoir & Fluid

The power steering reservoir on the W211 & W219 platform have a filter built in. This filter is not serviceable, meaning that you need to replace the reservoir if you also want to replace the filter.

I took the liberty to replace the reservoir/filter and also flush the complete system and put fresh new synthetic oil in.

I used a vacuumpump to get most of the old red mineral fluid out. Then replaced the reservoir and used the “lock-to-lock” steering motion to pump all the old fluid out. Temporarily cap off the return line on the new reservoir and extend the return line to any suitable container for the old fluid.

I used about 2 liters to flush the system and 1 liter to fill the system. Febi Bilstein CHF 11-S Nr. 06161 is the correct fluid for this system.

Steering goes noticeably lighter after this service!

Almost done flushing (fluid is becoming more green/blue-ish)
Made this shot after removing the reservoir. It clearly shows why replacing the serpentine belt is a bit of a hassle there…



Mercedes CLS55 AMG W219, Servicing The Supercharger Oil

One of the most common overlooked service items, is replacing the supercharger oil. The gears of the supercharger spin very fast and need proper lubrication and cooling. Because it spins so fast, it requires a special type of oil: Mobil Jet Oil II (Synthetic Jet Engine Oil).

This oil is not that widely available to customers and also not very cheap. I used a 150ml syringe with some hose to extract the oil and fill it up again. It holds 150ml maximum, but you can never get all the oil out unless you remove the supercharger. I removed about 130ml, and put back the same amount in fresh oil.

Extracting the old oil
Used a plastic containter to hold the oil in, which makes it a lot easier

Mercedes CLS55 AMG W219, Some Statistics

Someone asked me on a forum how many kilometers per litre the CLS55 does and I was happy to share that information with them. Yes it’s a big engine with a lot of power, but when you treat it gently it can be quite economical for it’s size.

I achieved a respectable 1:8.5 over 155km (mostly highway) with cruising speeds around 120km/u. Also the fuel gauge indicated a half tank when I had already driven 350km’s, which suprised me!

I love the white gauges in the black dashboard ๐Ÿ™‚



Mercedes CLS55 AMG W219, Brabomeet 26-06-2022

I have been a member of the Seat forum Seat-Online.nl for quite some time and the Brabomeet is always a fun and nice small meet around Eindhoven. I made some pictures while I was there.

I love the timeless look of this car…

2 Videos were created, where you can hear the mighty V8 M113k Mercedes engine ๐Ÿ™‚




Mercedes CLS55 AMG W219, Replacing The Serpentine Belt

Replaced the serpentine belt, under the guise of “while I am in there”. It was quite a hassle, but unfortunately, I will do it again as this belt seems a little short to my liking. The tensioner has ample room to move this way, which is not how I like to see it.

I replaced it with a Dayco 6PK2440 belt if I am not mistaken.

New and old belt

Mercedes CLS55 AMG W219, Cleaning The Belly Pans

After changing the oil, I was left with 3 dirty belly pans. Actually, the first one was pretty clean. But the 2nd & 3rd were really dirty due to oil leaking and dirt accumulating on that oil.

But a good degreaser and pressure washer work wonders. I totally forgot to take ‘after” pictures, so you will have to believe me on this one ๐Ÿ˜‰

1st belly pan (pretty clean)
2nd belly pan, which was quite dirty. nfortunately, it has 1 broken air diverter
3rd belly pan, this was really dirty!



Mercedes CLS55 AMG W219, My First Oil Change With LiquiMoly 5W40 High Tech

Performed the first oil change on the CLS55 with LiquiMoly High Tech Low Resistance 5W40 oil. Bought 2x 5 Liter canisters, as the big 5.4 Liter takes about 8.5 Liters of oil in total. Also added in 1.5 canister of LiquiMoly Ceratec, a well known working friction modifier.

List:

  • 2x 5 Liter LiquiMoly High Tec Low Resistance 5W40
  • 1x Mann Oil Filter HU718/5X
  • 2x Mercedes Oil Sump Plug A3529970032
  • 1x Katsu Oil Filter Wrench Set

This was my setup for the day, used 2 ramp, which has enough ground clearance.

This is how the oil filter looked. It was in a bad state, seems the previous owner skimped out on maintenance…The rubber O-rings especially were very old and worn.

The M113k engine has 2 sumps, a front scavenging sump and in the back the main sump. I saw a lot of oil leakage, most of it was due to the rocker covers as far as I could judge for now.

Putting the Katsu oil filter wrench to good use. I used a combination of a vacuumpump with the drain plugs to get most of the old oil out

Performed some other things “while I was in there”, but I will describe that in separate posts.




Mercedes CLS55 AMG W219, Replacing The Rear Differential Oil

1.5 Liter of 75W140 GL5 Differential oil (LiquiMoly) and 2x new filler caps for the rear differential. I didnt have the correct hex key, but a T70 torx also works. Will be doing this again in the near future, so all the old oil is replaced with new oil.

I used a big syringe (150ml), which actually worked out very well. I will always recommend using new plugs whenever you notice that the plugs look old.

Mercedes CLS55 AMG W219, Replacing The Rocker Cover Gaskets

When I replaced the spark plugs, I noticed some massive oil seepage/leaks from both the rocker covers. I bought the original Mercedes liquid sealant for the breather chambers. I already read that this would be cumbersome, and that was no lie.

But it’s all in the preparation (degrease properly!) and take your time for that, because this is not something you want to do a couple of times.

OE Mercedes sealant partnr: A003989982010

I found out that a deep 18mm socket and 1/2″ extension enabled me to use a kit gun, essentially making the job way easier! If you look closely, you will see the setup in the back of the photo.

Happy to see that all looks well under the rocker covers ๐Ÿ™‚




Mercedes CLS55 AMG W219, Replacing K&N Air Filters With OEM Paper Air Filters

Replaced the K&N drop-in filters with OEM paper filters (Febi Bilstein), as I prefer better filtration over a little more throughput. I don’t think I will notice the difference with my standard CLS55 AMG.




Mercedes CLS55 AMG W219, Replacing The Cabin Filter With Mann FreciousPlus Filter

Replaced the cabin filter as I did not know when it was last replaced. I was unaware that Mann had a new type of filter, which transcends the pollen and active carbon filter type.

Their FreciousPlus series is also anti-bacterial, making you stay as healthy as possible within your car ๐Ÿ™‚ I used Mann FP3172 for the CLS55. As you can see, it needs to be replaced every year or 15.000km.




Mercedes CLS55 AMG W219, Replacing All 8 Coil Packs

After about 187.000km (or 17 years), the original coil packs are due for retirement in my garage ๐Ÿ˜‰ Car seems to run a little better after placing the new coil packs!

Could also be placebo effectโ€ฆ ๐Ÿ˜‰

Mercedes CLS55 AMG W219, New Vband Clamps For Non-Resonated Catback Exhaust

On of the previous owners clipped something, as the Vband clamps for the non-resonated catback were damaged and therefore leaking (a little bit).

I replaced both of them with brand new clamps, so the seal is airtight again!

Damaged Vband clamps (scraped & dented)



Mercedes CLS55 AMG W219, Replacing Rear Swaybar Links / Droplinks

The rear swaybar still had the original droplinks, so they were in dire need to be replaced. I replaced them with fresh new droplinks from Febi Bilstein. This tightens up the rear of the car a little bit. For maximum effect, I will need to overhaul the complete suspension (which I will be doing in time!)




Mercedes CLS55 AMG W219, Changing The 16 Spark Plugs With Beru Ultra Titan UPT14P

Replaced all 16x (!) spark plugs with fresh new Beru UPT14P Ultra Titan Spark plugs. They are pre-gapped at 0.75mm and I adjusted them to 0.8mm as per factory specifications.

They needed to be replaced a little while ago, too bad that some people skimp out on needed maintenance.




Mercedes CLS55 AMG W219, LiquiMoly Injector Cleaner

As part of regular maintenance, bought some LiqiuMoly injection cleaner. Will probably be using this every now and then as preventative maintenance.




Mercedes CLS55 AMG W219, New Exhaust Clamp Secondary Cats

New exhaust clamp for the secondary cats as the original one had a rusted bolt which could snap at anytime.




Mercedes CLS55 AMG W219, Meyle HD Gearbox Mount

Engine mounts are usually forgotten as a maintenance item, but not for me! I checked my options and found that Meyle had an upgraded mount in their product line. The upgraded series from Meyle are known as the “HD” series and they are OEM+ replacements.

I chose the Meyle HD gearbox mount to replace the factory Mercedes mount. Fitment 100% and the build quality looks to be very good. The front engine mounts will be replaced as well by Meyle mounts!

Mercedes CLS55 AMG W219, Replacing The Bonnet Struts

I don’t get people who live with worn old bonnet struts. They dont cost much and they make all the difference, especially if you work on your own car.

They were still the factory bonnet struts, so probably 17 years old.




Mercedes CLS55 AMG W219, Replacing The Flex / Giubo / Hardy Discs (Prop Shaft)

Noticed at a routine inspection that the prop shaft flex discs (also known as giubo or hardy discs) were showing quite some wear. After 17 years, that is to be expected. But to be honest, I thought they would have been replaced already.

Replaced them with Tedgum discs including new shiny bolts. Happy with the end result as I felt a more positive engage from the drivetrain. Job done!




Mercedes CLS55 AMG W219, Replacing The Airmatic Air Filter

Replaced the Airmatic air filter, which makes sure that dirt & debris stay out of the Airmatic system. Mercedes uses a fuel filter, repurposed as an air filter for this system. The partnumber is: WK 32/6 (Mann filter)

Mercedes CLS55 AMG W219, Replacing The Airmatic Compressor

With 186k kilometers on the clock and 17 years old, its good to start replacing parts as a preventative measure. After 17 years, rubber will be hard and brittle and electrical components might show fatigue or arent as “snappy’ as 17 years ago.

The Airmatic compressor (and relay) works hard to keep the 4 air springs inflated and after 17 year, its time for a rebuild or a pension ๐Ÿ˜‰ I chose rebuild (and pension), so I always have a good one as spare. For good measure, also swap the Airmatic relay!

Unfortunately, normal silicone boost/vacuum line is not suitable for 10-14 BAR working pressure ๐Ÿ™‚ It went bang on me!



Mercedes CLS55 AMG W219, Midlife Crisis Officially Started!

18th of May 2022, the day I became 40 years old and my mid life crisis officially began ๐Ÿ˜€




Mercedes CLS55 AMG W219, Bosch Intercooler Pump Upgrade

The infamous Bosch “010” upgrade pump for the watercooled supercharger circuit.

As I replaced the pump, it seems one of the previous owners already placed the Bosch 010 pump. Nevertheless a worthy replacement, as I have zero idea how old it was.

Mercedes CLS55 AMG W219, Repairing Broken Cable Boot Latch

Broken cables in the rear hatch. Its a common issue on the C219 W219 platform (probably also on W211 platform).

Functions that ceased to function were:

  • Boot handle
  • Auto Close button
  • Lock button
  • Boot light (intermittent)



Mercedes CLS55 AMG W219, Orange Brake Calipers?

Absolutely love this color on the AMG calipers. Might have to do this on my CLS as wellโ€ฆSomething for later ๐Ÿ™‚




Mercedes CLS55 AMG W219, Converting The 12v Socket to 2x USB With Voltage Gauge

Modified the cigarette lighter with a voltage gauge and 2x USB charging ports, which is way more relevant nowadays.

Took some small modification to make it work, but it looks good and is very useful.

The OEM unit as is
Rearside, you have to remove the KeylessGo module and a small bulb holder. Then use some force to push the plastic retaining clips and wiggle the cigarette lighter out
End result
This is how it looked like on the Mini



Mercedes CLS55 AMG W219, Inspecting The Bottom Rear Side

Was a little curious to see what I would encounter so I made a picture of the bottom rear side. All the accumulated dirt in the differential heatsink was removed and cleaned thorougly, so it could function properly again.

The rest looked good, no rust issues, other than some surface rust on some parts. It also gives a good look on the modified exhaust (center resonator delete).




Mercedes CLS55 AMG W219, Replacing Old Worn Center Caps

The wheelcaps had seen better days and have been replaced with fresh ones. These are the small mods/repairs which actually make a bigger difference than one might expect.




Mercedes CLS55 AMG W219, Weighing The Rear Tyre

Weighed the big wide rear tyres. They come in around 24.5KG which isnt that bad!

Specifications: 285/30/19 Hankook S1 Evo 3 on a original Mercedes AMG 19 inch 9.5j wheel (staggered set).




Mercedes CLS55 AMG W219, Replacing The Rear Air Springs / Bags

Changed the air springs on the CLS55, just as a precaution. With 186.000 kms on the clock, that is not a bad thing to do. Replaced them with eBay units.

They are holding very well so far ๐Ÿ™‚ !

Mercedes CLS55 AMG W219, Special Tool For Replacing Engine Mounts

Bought a special tool, which is particularly handy when replacing the engine mounts on a CLS55 W219 or E55 W211. The exhaust manifold takes a fair bit of space on each side of the engine and there is where this tool comes in handy with removing the bolt which sits directly under the exhaust manifold (on each side).

Bought it from eBay: https://www.ebay.com/itm/125234922812

Mercedes CLS55 AMG W219, Upgrade To Hella LED Side Lights T10

With the upgrade to new Osram Xenarc Classic bulbs, I wanted to replace the W5W/T10 halogen side lights, as they simply look out of place.

After a extensive review of Sergiu Gabor, I opted for the Hella LED Retrofit bulbs. Fitment is 100%, they are canbus friendly (no errors) and they give a nice white uniform light, which is exactly what I was looking for.

Mercedes CLS55 AMG W219, Upgrade To LED License Plate Lights

Converted the license plate lights to LED units (thanks to Aliexpress). Instantly gives the car a more modern look. I applied some dark window tint film, to tone down the intensity. Too much LED light gives off a “chav” image, which is something I want to prevent at all times.

Mercedes CLS55 AMG W219, Forgot How Wide The Rear Tyres Are…

I had to do an visual inspection of the rear airbags of the Airmatic system and when I looked at the rear tyre, I totally forgot how wide they are…They should be, else it would be very hard to get all that power on the floor!

Mercedes CLS55 AMG W219, iCarsoft Diagnostics v3.0

A DIY mechanic wants and needs to know all about their car, and a proper diagnostics program/unit is therefore invaluable. I opted for the iCarsoft Diagnostics unit v3.0. I will probably look into Xentry/DAS in the near future, but having this small powerful device in the car is a godsend.

Its powered by the car, so essentially hassle free! Don’t forgot to update the unit using the software on the iCarsoft website.

Mercedes CLS55 AMG W219, Replacing the Supercharger Pulley Bearing (Nachi)

I decided to replace the supercharger pulley bearing with a fresh new Japan made Nachi bearing. One of the easiest way is the hot/cold method, where you heat up the pulley and freeze the bearing itself. This results in the bearing sliding into the pulley with relative ease.

I could’ve also used my workshop press, but I didn’t want to force it in. I followed this guide for it:

Mercedes CLS55 AMG W219, New Coolant Expansion Reservoir Cap & Oil Filler Cap

2 Items which are forgotten very easily in routine maintenance; the coolant expansion reservoir cap and the oil filler cap. The coolant cap is spring loaded cap (mechanical component (!)), which is usually set to 1.1 BAR, to allow the coolant to vent whenever the pressure is too high. But when it vents too fast (spring lost tension), the coolant system is not able to operate efficiently.

Therefore its a good habit of changing these out every now and then. For the couple of euros, it should not be forgotten.

I also swapped out the oil filler cap, as this was leaking/seeping out a little bit of oil.

Mercedes CLS55 AMG W219, a new chapter

Sold the Mini Cooper S R53 JCW not too long ago to pursue my dream of driving a V8 powered car with a lot of muscle.

I have been investigating for over a year what I really wanted to drive. Started with the E55 AMG W211, but the looks (especially the interior) looked a bit dated to me. Until I found out that the W219 chassis had the same engine in it, the CLS55 AMG.

I found one close by (there were only 3 on sale at the time) and after a good chat with the owner and a marvellous testdrive, I bought it. Absolutely love the car! A lot of maintenance has already been done by me and a lot still has to be done. Im happy with somewhere between 500 and 600BHP, but that is something for later.

Enjoy the pics!
