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, 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.


  • 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 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 🙂 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 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)

Volvo S80 2.4T JR Jetex Uprated Panel Filter

Decided to buy a panel filter from JR / Jetex. Build quality is nice, but could be better. Fitment looked like 100%, but unfortunately that wasn’t the case.

I tried to modify it a little bit, but that went wrong and I had to throw it away.

Volvo S80 2.4T BSR Optiflow Kit

Bought a new BSR Optiflow kit as I wanted a little bit more blowoff + compressor noise. I can also fit my Velocity Stack filter (150mm diameter).

It has been sold in the meantime as the extra induction noise does not fit the S80 to be honest.

BSR Kit: 4900705
Max HP: 410 HP

Volvo S80 2.4T Dirty vs New Airfilter

Replaced the air filter. This is what a dirty airfilter looks like.

Change it on time, so your car keeps performing at peak efficiency!

Volvo S80 2.4T Changing the Interior Combo filter

Needed to change the interior / combofilter and was suprised by this malformed unit.

Looks like someone didnt do their job properly…Shameful really.

Easy DIY job, which shouldn’t take more than half an hour.

Volvo S80 2.4T Denso Injector Service

Decided to clean and service the stock Denso injectors. Rubber rings get hard and brittle over time and tend to leak. Also the filter baskets might be contaminated over time, especially if the fuel filter is not part of your regular service intervals (which mine S80 lacked…).

I bought this kit of Aliexpress and the quality looks very nice. It contains all the items needed, including a special tool for removing/mounting the filter baskets.

The pictures will speak for themselves (it was needed!).
