My MacGuyver method for repairing the airline did not hold out very long, so I needed something structurally. Fortunately, Mercedes sells a piece of airline (1.5m) for repairing/maintaining the Airmatic system, which was exactly what I needed.
Partnr: 2203271045 / A2203271045
Costs: about 20 euro
I’m a sucker for gadgets and I always wanted to try out the Osram Airzing Mini air purifier. But at the time, retail price was about 50-60 euro’s, which was way too expensive.
In the meantime, it has dropped to about 15-18 euro’s which was ok for me to give it a shot. To be honest, I haven’t really noticed improvement, but I always had a ioniser in my previous cars.

Price has already gone up again!
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.
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)
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!
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.
Bought a Teflon (PTFE) intake spacer for the intake manifold from Thermatec. It will isolate the intake manifold from the warm engine, which will result in lower intake temperatures. The phenolic spacers are identical in function, only the material used is different.
Lowering the Intake Air Temperature (IAT), will result in higher power figures. A simple supporting mod, which is quite inexpensive.
Pro tip: make a small indentation in the top left corner of the spacer where the bolt would go through the spacer/gasket (where the thermostat housing is), this will make the installation a lot easier due to the restricted space in that area.

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
When I bought the car, it was missing a skidplate. A skidplate has a number of purposes, like protection, keeping dirt out, but also improving underbody aerodynamics and improving cooling and fuel economy of the car. A car is cooled by pulling air through your radiator (by the flow of lower pressure air under your car), instead of purely relying on high pressure on the front of the car.
I bought this Rezaw-Plast one via Motointegrator.de and it had a very good price (33 euro is a steal!). Fitment is very good, aligns well with the stock mounting holes.
Partnr: RP151901 / 151901 / 8634813 / 30741855 / 8624664 / 30741968
Replaced the air filter. This is what a dirty airfilter looks like.
Change it on time, so your car keeps performing at peak efficiency!
