My co-worker 's SL600 (R129) ASR light keep lighting up and the car is now on limp mode and barely can drive it. Dealer wants $12,000 to fix!!! anybody know what's wrong? $12k to repair is ridiculous.
the car has about 60k miles on it.

 

need OBDII codes to know what's wrong..can be ALOT of possibility

 

what was the estimate for? If it needs a hydraulic unit or a combination of things it may be that much. Possibly a problem with the hydraulic suspension. let us know what exactly the dealer wants to replace.

2003 c230k magma, c5, c7, 6 spd.

 

$12K to repair a V12 car is not ridiculous at all. That's why used ones are cheap.

 

i believe that many of the repairs on the 12 cylinder and 8 cylinder of the same year and model are pretty much the same, except for things like extra spark plugs, a different coil and post 2003 turbo chargers. correct me if i'm wrong. oh, and maybe the brakes are upgraded.

 

if the car is old enough, pre 2005, I have Carsoft available, and I live in socal also, so I would be willing to help you out with the codes, 2 years ago my C320 also went into limp home mode, but I replaced the transmission our selfs, saves a whole lot of $$$.

 

throttle valves for those are around $3200 each and they have 2 so I am not suprised at all. They go out often

 

Yeah its the Electronic Throttle Acutator. very common problem on the 600 you will need two of them/

But it can be fixed for under $1000. Some ETA can be rewired. The problem is they used biodegradable wiring insulation and its causing problems

google search for ETA mercedes

 

where, or how can these be fixed?
