The ten common failure areas of the w220 chassis
These cars are remarkably robust and will go 200k miles easily but there are some common failure areas I will list here
In the coming days I'll also link to cheap repairs for most items
1. Crank position sensor (cps)
2. Electronic accelerator pedal
3. Leaky transmission plug
4. Airmatic (s430 and s500) or Abc suspension (s600 and s55, some s500)
5. door control module
6. Front control arms /ball joints
7. Theft related parts (alarm siren , ecu, eis, key, shifter)
8. Water damage from Sunroof drains , reed valve , or taillights
9. Instrument cluster (if not fixed under recall or extended warranty )
10. For v12 cars only - coil packs and ignition transformer

Airmatic still frightens me. And the transmission sometimes thumps under hard acceleration. And 16 sparkplugs!!
But, it's a great car to be a passenger in and as a used car it's tremendous value! For a long trip it's hard to beat!

Don't forget, If you have an old W220. Replace all those f***ing TYCO relays with some good Hella's. Because of those relay's, My Airmatic pump blew up. So did my starter motor......

2. Electronic accelerator pedal
4. Airmatic (s430 and s500)
6. Front control arms /ball joints
I'd add
Front CV boots.
False SRS sensor reading from noisy switch.
