Hello…no workshop can help me, probably immobilizer ! The following problem: Vehicle only starts when the “inner room” has approx. 3-4 degrees max. (or less). Even the outside temperature doesn’t matter, because if it is minus degrees and the sun shines on the dashboard, then nothing works either. If it is warmer, it goes off briefly and immediately again as if you pull the plug. Was already at two free workshops, but they had no access to the engine control unit, Audi It has tried and no access to the M. control unit. Suggested solution, new MSG for 1000,- install. I read a lot about the immobilizer, many went the same way. Has most of it been due to the cable of the reading coil. I bought this and wanted to install it today, steering wheel and cladding removed + instrument panel…free field of view, but no immobilizer seen…where to the vulture is the ? All cables bundle back towards the motor, also the 2 pole cable of the reading coil. .. Help…no one really knows!
