diagnostic service
It only take a few minutes to pull the codes from the computer. How long the dealer wants to put down as labor depends on them and probably how well you know them.
Average labor is between $90-$100 a hour, so plan accordingly to that rate. Most from what I've seen is an hour they put as labor to pull codes for diagnostic.
Good luck.
I think the first year w220's had a problem with the air compressor for Air-Matic, but that was only on some cases.
Get the fuse/relay sheet out from the spare tire area.
The realy is under the hood on the passenger side fuse box.
The relays usally get hot and stick causeing them to burn up the air pump.
