Hello have a real professional-connaissance question Right now I am really speechless and got to deal with the fear when I was in a Mercedes workshop today…I find a complete rip off, and the error is in my opinion a wrong diagnosis of those. Mistakes of my SLK 200 (no compressor) Bj 2000 (before the facelift): *Key pure, at the first switching position people all instruments quite normal BUT at once the fan goes on and if I want to start it in the second S stop position, he should start normal white, what he does not do !!! (Total rest in the last switching position when trying) If I go back to a switching position, everything will continue to run as normal as the fan and try again then completely blocks the second switching position. The answer of the WERKSTATT: engine control unit has a wobble jam…SINCE SOLUTION a new must be coded and built and that for 1700 € !!!! This can not be…er sprin That happens 1-2 times only in the month, where he does not start, after a few attempts it always works. Please help me… Mfg Sven
