I am absolutely desperate and hope that someone can help!!!!!
I have a 2013 manual VW Passat with a faulty ECU (EDC17). In February this year the car just would not start and it turned out that the ECU was water damaged. Dried it out and put it back in the car and everything was fine for a few months Then about 5 months ago the engine management light and airbag light came on a stayed on then 2 months ago the coil light started flashing and car kept going into limp mode. When checked it said it was turbo...sent turbo off and they sent it back as it was ok. Garage got a second hand ECU unit with same codes except it was from an automatic. Cloned ECU but cannot get the immobiliser codes from old one to replacement one. They ordered a pin thing that they thought would do the the immobiliser but it hasn't!! The car has been in the garage for 4 weeks and its back to the way it was before (lights on dash, limp mode, turbo code) and garage said they do not know what else to do!!!!
I am in the UK and am hoping that someone can help me with this problem or is it a case of I have to take it to VW and have to pay a fortune???
