A4 TDI Imobilizer Fault?

[Glen Chamberlain]

HELP! I have a MY98 A4 1.9 TDI. The centre part with the computer bit in the dash fades almost into nothing when the cabin gets warm but it nearly perfect when cold, so i pulled out the binnicle to have a peep. Quickly found what i thought, i cant fix it! So i put it back.

NOW the bloody car wont start!! The yellow key (presumingly imobilizer light) is flashing with the ignition on. It starts and then imediatly cuts out? I guess the car needs recoding to the keys, question is how? oops? can of worms comes to mind

Any help greatly appreciated

cheers

have you got access to vagcom? it can be done through that.you may have to have a code though that came with the car.

Not got the plastic tag with the code on but i do have lots of info on data stickers, and i think the the code may be on there. I do have access to vag com but not sure how to do it?

go to the rosstech website and download the manual in pdf it should be in there,have you got the full version?as the unregistered version may not let you do it.I believe its quite simple.

Earlier a4's have often reading coil faults. Your car is sligtly newer than they usually are, but I'd still guess the key reader is faulty.
