ECU or Immobiliser Misery
Hello all,
This is my first post on your forum. I have read through a lot of the previous threads to diagnose my Audi’s issues; however I cannot seem to find the relevant information so to the extent I am posting this thread in the hope your experts can point me in the right direction to get a resolution to my problem/headache.
Please see below relevant car information:
· make Audi
· model A3
· spec of car TDI Sport
· engine size 1.9
· fuel Diesel
· year of car e.g. 1998
· reg of car R
History:
I have experienced the following problem where by the car will just cut out whilst driving. The car will restart after 2 - 3 minutes, which can be a bit of a distraction when in London traffic. I took the car to a local garage who wired it up to a VAG COM program, they diagnosed it as an immobiliser issue, the garage reset the ECU or cleared the immobiliser, ‘I think’, also stating that it could be the Key barrel that is slightly worn and this maybe triggering the immobiliser whilst driving.
However this reset did not resolve the issue, so I got an immobiliser company to plug into the ECU, they stated that they feel the ECU is not communicating with the Dashboard.
The car is now immobile, I have called out the AA they disconnected the fuel line and reconnected it and the car started? I let the car run for 20 minutes. I restarted the car the next morning to check all was ok but didn’t drive it. On my return from work I tried to start again but same problem the car would turn over but would not start?
I spoke with a friend who suggested I take of the negative terminal from the battery and leave it for a good 10 minutes then reconnect and try to start. This worked I let the car run and took it once around the block. However when I came to turn it over again the following day the car does not start.
Is this an ECU issue? If so would you advise to replace or simply get AUDI to fix it? My concern is that AUDI charge £125 and hour and I have just paid for service MOT and much more cost is not viable as I wish to sell the car to get a newer model.
All advice would be very much appreciated.:Blush:
