I have a used but guaranteed 100% functional A 002 542 65 18 steering angle sensor for a W210 chassis car. I bought it new thinking mine was bad when it ended up that the alarm module had blown the fuse that feeds both it and this sensor. (duh!) This lists new for $362.00, most dealer parts sites sell it for around $265.00, I'm offering this one for $175.00 shipped anywhere in the CONUS with a guarantee of not DOA.
Determination of fitment is the buyer's responsibility and not a reason for return, so make darned sure this fits your car if you want it.
