Hello everyone, Wondering if anyone can help me. A few weeks ago my EPC light came on and immediately went into limp mode and started jumping when driving at 5mph. After a few hours I came back to the car and it was fine so I drove it to my storage unit. I came back the next day and when starting it the EPC light and EML light were illuminated and the idle was quite rough. I came back to it about a week ago and all the doors were locked, the key isn't unlocking it and the barrel of the central locking isn't even turning. The ignition seemed to be on aswell. I'm really at a loss of what to do. We had some hard rain that week the vehicle was unable to be opened so im hoping water hasn't gotten into the BCM but I'm not sure. Audi S5 V8 4.2 2008 Any help would be great, thank you all. Kian

Do please let us know the outcome.

Main Audi dealer will be minimum £200 per hour for a technician, not a mechanic. As suggested, find a trusted independent and expect to pay for health report. A 16 year old car, if serviced properly can still be kept on the road, however, except you'll need to budget for some of the repairs. You don't need to do everything at once. What's critical? And what's worth doing, say in 6 months.

If the Audi dealer found no faults at the first diagnosis how much reliance can you place on his second attempt? Then there is AI which has given you a list of possible faults, but no certainties. Are you going to spend money on that basis? I suggest you find an independent VAG specialist who can test the car with a decent code reader such as VCDS, and let him do the diagnosis before committing to any expenditure.
