Mercedes CLS55 AMG W219, Heatwrapping The Intake Tubes

A mod which has been tested on MBworld already, heatwrapping the intake tubes to keep as much heat out of them as possible. I had white heatwrap lying around, so I used that 🙂

Small supporting mod and a very easy DIY.

Work in progress



Mercedes CLS55 AMG W219, Leaking Rocker Cover Gasket (Again)

Last time I will be using gaskets from Febi Bilstein as the rocker cover started leaking again around cilinder 4. Replaced it with a Viktor Reinz gasket. If it will leak again, I will buy them from the Mercedes dealer.

Mercedes CLS55 AMG W219, Replacing The Engine Mounts With Meyle Mounts

As part of further preventative maintenance, I replaced both the engine mounts with fresh new Meyle engine mounts. Unfortunately no HD version available. Next time I will probably replace them with Mercedes Black Series mounts, as these are a popular upgrade.

It’s highly recommended to replace them, as it makes a major difference!

New mounts with the covers
Meyle (new) on the left and old on the right. I almost thought that I ordered the wrong ones as there was a clear height difference. But they sag over time, so that is to be expected.
Its highly recommended to have this tool ready as this makes it a lot easier to undo the top nut!



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 🙂



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 🙂




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, New Intake Pipes (Gold Tape Heatwrap)

Noticed that one of the plastic intake tubes was broken, so I replaced them both. Fortunately, the intake pipes only costs 11 euro per piece, which is a steal!

I added gold plated tape, to fend of radiating heat and keep the incoming air as cool as possible. Took quite some time and effort, but I am happy with the end result and how it looks in the engine bay.
