Some of you may remember I had a problem when I bought my car in that the horn would sound whenever I removed the key from the ignition. This was diagnosed by an auto electrician as a faulty front SAM unit. When I spoke to my local dealer they confirmed that this is a common problem and the front SAM's were a common replacement item. I tried getting one from V12 on the cheap but I heard conflicting views about if they need to be coded or programmed to the vehicle or not. I tried my local dealer who I have never got on that well with and they just confirmed my thoughts that MB dealers are all t@ssers!! I then tried a dealer in Leicestershire where I bought my first C180 from and my father has bought countless new MB's from, the parts dept were very helpful and friendly and said yes it needs to be ordered to the chassis number and then programmed once fitted to the car. He said he could order it then once it arrives I could fit it in the car park and then the service dept would plug the car in to the computer and code it whilst I wait and charge me half an hours work. Fair enough I thought, so I ordered it back in July it arrived last Friday!!! I phoned today to arrange when would be best to come and fit it and get it coded, 'We would need your car for a day and it will cost 2 hours @ £76/hour'. So I explained what the parts man told me about fitting it myself and getting them to code it, 'We cant do that Sir! We have to fit it here' I said to her, 'You're funnier than the Two Ronnies!, 2 hours @ £76/hour for replacing a part that I have removed and replaced in less than 10 minutes. You have been rumbled, what a scam!!. No reply, just a nervous giggle!!! So basically does anybody know a dealer or somebody who works for a dealer who would code a new SAM unit for less than £152?? Otherwise the warranty company will be getting another claim soon.
