Mercedes CLS55 AMG W219, Replacing the 722.6 Gearbox Conductor Plate & Transmission Fluid Refresh

As part of the big preventative maintenance, I swapped out the conductor plate for the 5-speed 722.6 automatic torque converter gearbox (which is pretty much bulletproof) and also did a fluid refresh. Its almost impossible to get all the fluid out, that is done better with a flush (done with specialist equipment).

10 liters of LiquiMoly Top Tec 1800 ATF fluid

New conductor plate

Valve body & old conductor plate. See the black residue, time for some cleaning
More of that black residue…
New conductor plate fitted, cleaned the valve body as much as possible
Valvebody back in place, new filter mounted

I replaced almost 6 liters, the rest remains in the system off course in the coolers and the rest of the transmission plumbing. Maybe somewhere next year do this again, but also replace all/some solenoids and go to a transmission specialist.

Pro tip: Transmission adaptation reset is mandatory! I used method 2 of the video below




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!

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, 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.

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.

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 🙂




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.

Mini Cooper S R53 JCW – Servicing the Eaton M45 supercharger

When I bought the Mini, it had reached the 160.000km or 100.000 miles mark. This is a milestone in the Mini Cooper S service history, because it means that you need to service the Eaton M45 supercharger (new fresh supercharger oil etc etc).

I saw the episode from Wheeler Dealers and felt confident. It was a lot of work, but fortunately it wasn’t complex. As this isn’t my daily driver, I meant I could take the time.

I also replaced the supercharger coupler with a new oil filled nylon coupler (in red).
