some info to all who suffer from starting \ immobiliser problems. This is by no means a recognised repair or long term cure, but it works.

I bought a 1996 A4 2.6 V6 with an Autostyle body kit in May 05. Almost from the start it occasionally cut out during starting. I consulted with a work colleague who is a big audi fan. He suggested I join this website, which helped me identify a probable immobiliser issue.

The problem has been ongoing ever since, sometime taking 5 or 6 attempts to start, often at the most inopportune moments.

Anyway, in desperation about 6 weeks ago I flooded the whole ignition area with WD40, and I mean shitloads. Up the barrel using the thin applicator pipe, outside the barrel, in the plastic surround, and for several days had greasy stains on every pair of trouser I wore. BUT, it has not cut out since, not once.

I suggested this to an A4 friend with similar symptoms, who rang today to let me know his car has been completely start-trouble free for 3 weeks now.

As I said earlier this is not a repair, and if the idea is already out there somewhere, I apologise for repeating it, but I just wanted to share something with the forum that has worked for me and for one other so far.

Let me know if this helps anyone else.

Very Happy Very Happy Very Happy

had this problem myself,I stripped off the bottom cowling and took off and re-connected the wires for the immobilser the problem never appeared again, I think its just down to a poor connection hence the wd 40 trick helping but ,it may re-appear after the wd 40 has dried out be warned,nice talkin to you

cheers Caluma6

hi caluma, stupid question i suppose but how did you get to the immobiliser wires/unit? what colour are they and/or what does the unit look like? i've tried and died - and the wd40 only does the trick for a while..... Embarassed

the immo unit is mounted behind the knee board below the steering
column... it is bolted to the center console side and is white/ yellow
coloured...
click out the connector and spray it with some 'contact spray' which is
better than WD40....

hi, thanks for that. found the off white box no problem and cleand up contacts using switch cleaner fluid. unfortunately no improvement so assume it has to be the other end at the spool reader/ignition switch. if only it was that easy getting to that!!

I know!

couldn't get the airbag out of the steeringwheel when I had to replace
the electric/ switch part of the ignition barrel. So I had to break the
lower steering column panel away....

cleaned the connector on the reader coil now I had the chance...

ordered the new cover today which I need to 'dremel' to fit the remaining
plastic...

didn't have a big problem taking wheel off when i changed it for a leather 3 spoke one. just disconnected the battery, removed the 3 torx bolts under the wheel (25 or 30mm i think) then disconnected the wiring and unscrewed the nut. same in reverse apart from leaving the ignition key in and turned on when the battery was reconnected to reset the airbag.
only problem, as you say, is almost or totally destroying the concertina plastic thing.... nightmare... so gave up hope off getting to the ignition barrel/spool reader. if you find an easy way, Smile please let me know and i'll give it another go.....

Hello, apologies for dragging up an old post. I'm trying to find this imobiliser module behind the dash on my 1997 B5 1.8t. I have stripped nearly all the dash out but can't see it. I guess it must be near the radio buried at the back? photos on the net are all left hookers and they are easy to find. Help and pics much appreciated. Cheers Nick
