I am tempted to say if the dealership was sincere, they would already have fixed the problem. However, since they don't know whether they will sell the car, they won't invest in repairs. But from what you wrote, it sounds like they will not repair anything, just reset the codes.

I recommend finding a good tech who knows the car and can give you an honest opinion. If he/she says the CEL is a minor issue, then go ahead with it. Otheriwse, there are many more to choose from.

For the peace of mind I just ordered an inspection by SGS for $99.50. I am curious about the results.

Thanks for all inputs. Nice, helpful people of the forum as always :).

Thanks Deanyel. The web site http://www.obdii.com/ has only instructions on how to test for GM and Ford vehicles. Do the same test procedures apply to MB cars?

In this section - http://www.obdii.com/connector.html, under the section titled "What Communications Protocol...", it explains that Euro cars are ISO9141 and that such cars utilize contact pins 4,5,7,15 and 16. They make it sound like all Euro cars are ISO without exception.
