Just thought I would put the feelers out to see if anyone has ever heard of the major problem I have come across. Basically was called in by a customer to recover his car after a friend of a friend of a friend decided to do him a favour and try and remap his car. His car being a minted 08 plate A4 2.0 TDI CR120 Avant. I did a scan of his car usng VCDS and it had approx 10 faults on the majority of modules. Now I consulted Shark Performance over this and took a copy of the scan log and cleared them all (apparently they were transient faults at the time) and then continued trying to remap his car which the customer was happy about............now here comes the interesting part. His ECU then decided to fail and go into hibernation as they call it. Remote access via Shark could not identify the problem so his ECU was removed and sent to Shark immediatley. Turns out that whoever had tried to map the A4 beforehand had caused a critical software confliction due to what he had uploaded to the cars ECU and it had shutdown...........Audi, Shark and a host of other tuning experts were consulted and the ECU was dispatched down to London for an ECU software guru to look at it..........even he couldn't get it to wake up. End result is one new ECU required for the A4. So if anyone is thinking of having their car remapped on the cheap then please take some time in doing your research about the company thats doing it as it can backfire and lead to an expensive recovery as shown here. Apparently this is the 1st time that this has been seen where an ECU will refuse to 'wake up' and thats using a multitude of professional software that head tech guys use.
