97 SL500
Electronic Transmission Control Module question...

The car is a '97 SL500 with about 45K miles. The check engine light is on and the dealer sez that they need to replace the ETCM. As far as I know, the car is operating just fine, just the light is on right now. The dealer wants $750 to replace. The car was recently in minor accident that required the bumper to be replaced, the air bags did not deploy, but the roll bar did (which the dealer had already reset). The light came on immediately after the car was picked up from the body shop by another dealership employee, so I haven't seen the problem first hand since the dealer still has the car.

So my questions: What's the risk on continuing to drive the car until something really stops working??? Could the accident have caused this??? How much would this cost to replace at an independent shop???

An "independant" shop cannot do it cheaper because they have to order it at the dealer.
I would not let an "independant" shop change control modules.
About the problem itself: fault codes?

The ETC is the gearbox controller. I didnt think it was connected to the check-engine light in any way.
[But EU cars of that age didnt have a check-engine light]

I'd get down to a local garage that has a scantool and get a list of the fault-codes that are causing the check-engine light. I beleive all local garages in the US will have a scan-tool

Normally if ETC is broken, either gearbox goes into "emergency mode" (which means 2nd gear only) or does really odd things. - but your car is running fine, so Id be slightly wary that this would help , and you'll then be asked to pay for the next thing they want to change ...

Aren't you still in warranty?? The dealer can read out the exact fault and replace the offending part. The accident and/or the body shop could certainly cause this problem.

It seems that your dealer invented something new: "non-active codes".
What are these?
Can you tell me which codes it are?
I am very curious about that "non-active".

If you do decide to fork out the $750, ask for the old part (just to prove they changed it!) and a guarantee that that will fix the problem with check engine light for you.

I'd still get a local garage to reset the check-engine light and read out the fault codes (and post them here) with a bog-standard scan tool ...

Do you really think there is someone in Germany who will stay awake from you?
(I do not know if this is a way of saying in English, but it means when something bothers you that it makes you not falling asleep)
