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 😉 I chose rebuild (and pension), so I always have a good one as spare. For good measure, also swap the Airmatic relay!

The new compressor in place. Unfortunately, the new compressor has a slightly different layout, so I worked around that by extending the air line. I used reinforced 4mm ID vacuum line to get it to work
Unfortunately, normal silicone boost/vacuum line is not suitable for 10-14 BAR working pressure 🙂 It went bang on me!



Time for a new car, VW Golf MK3 GTI 2.0 8v

And then it was time for a change, a new car. But it didn’t go smoothly, not at all. I traded my 2009 Toyota Aygo with a Volkswagen (VW) Golf MK3 GTI 2.0 8v (1996, AGG engine code), after having an extended test drive which didn’t show any weird signs. Car handled nicely, especially for that age.

But on the way back it broke down, RPM gauge dropped instantly and car died (electrics worked though). Long story short, I was pulled back home and was able to fix the issue a day or two later by swapping out the Crankshaft Position sensor (G28) and as a precaution, I also swapped out the Fuel Pump Relay (nr 30).

So a little bit of a headache & mixed feelings later, I am still very happy with my swap!
