SDJ Posted Sunday at 03:24 PM Report Share Posted Sunday at 03:24 PM Hi, I’m looking for help please. My A5 has been great for years but last week the ‘air pressure low , stop engine, ‘ came on and then went off . Popped to Audi dealer and asked to check. They advised ‘faulty oil pressure switch’ . Both switches subsequently changed , alongside oil filter . Ran fine for 3 days then engine management light came on. The dealership reset to zero but after 20 miles the light came on again. Dealer advised multiple faults showing on the computer, including throttle. Which is quite a big job apparently, and therefore big money. Car seems to be running perfectly but don’t want to get caught in the change every multiple fault part that will be a huge cost, if it’s just an electrical glitch or something when the switch was changed anyone got any advice please or is there a real Audi specialist garage I could go to Warwickshire /West Midlands to check Thanks for your advices. Love my car and want it sorted. Quote Link to comment Share on other sites More sharing options...
Steve Q Posted Sunday at 05:21 PM Report Share Posted Sunday at 05:21 PM How old is the battery? A failing battery can throw up all sorts of fault codes through electrical gremlins. What are the other issues it's throwing up? 1 Quote Link to comment Share on other sites More sharing options...
SDJ Posted Monday at 09:18 AM Author Report Share Posted Monday at 09:18 AM Hi , I’ve had the car for six years and I’ve never changed the battery, so at least six. When I got it it had only done 14,000 miles ( it’s only do 63000 now) so I doubt the previous owner would have changed the battery. In terms of diagnosis, I don’t have a read out, but I remember seeing oil pressure, airbag, throttle revs too much, there was one other but I don’t know what it was.thanks Quote Link to comment Share on other sites More sharing options...
Steve Q Posted Monday at 09:21 PM Report Share Posted Monday at 09:21 PM I'd definitely get the battery checked in that case. If it isn't then the airbag warning could be a loose wire under the passenger seat, oil pressure could just be the sensor/switch Quote Link to comment Share on other sites More sharing options...
SDJ Posted Tuesday at 07:16 AM Author Report Share Posted Tuesday at 07:16 AM Thanks. Diagnosis check next Monday and I’ll talk to the local Audi specialist about this to avoid main dealer charges. Quote Link to comment Share on other sites More sharing options...
