Please Help (Possible electrical fault) A4 :(

[a4TDI]

Hey guys

I have an Audi 1.9tdi (R Reg 1998).

Basically I switch the engine on (everything starts up fine) then when I use the left or right indicators they don’t work, and when I do the window wipers they do not work either. (They are both linked somehow)

I then switch the engine back on then they start working again, and then stop again. Basically they start and stop throughout the engine being on.

I have checked all the fuses in the fuse panel located on the inside driver panel.

It seems to me I haven’t checked all the other fuses or there is some kind of wire loose?

Any help or advice would be much appreciated.

i would probably rule out fuses as sometimes they work and sometimes they dont indicate a power supply is occassionally there.

I would look at more of a loose connection from the stalks, or an earthing problem possibly linked to the ignition switch?

check all the wiring looms from the steering column.

Just my 2p.

Yes it's really easy, 30 minute job. Go to:
http://www.audiworld.com/tech/elec.html
then page down twice and select Ignition switch replacement.
I've got a PDF of the article but you can't link straight to it for some reason.
The part no. you need is 4A0-905-849-B and my local dealer had one on the shelf as it's a common problem.

I'd say ignition switch as well (same thing happened to me). It is quite straight forward, but make sure you get the correct switch as there are different ones for the A4 (as I found out).

Also if you are driving the car around before you get it fixed make sure that the starter motor doesn't stay engaged after you start the car. This happened to me and I ended up having to change the starter motor as well which costs over £100 and is a pig of a job.
