Hi folks, not on my Octy, but last week we bought the Mrs an Audi A3 on a 52 plate with the same TDi 100 lump in it as my Octy (ok, mine is the 110, but basically the same). Anyway, the car had no tax so we only go it on the road this weekend.

Since then it's got a few funny little things with it, there is a whirring noise that is only present at idle, as soon as you rev the car is goes away. Also, the one-touch windows, although working, are behaving very eratically, they don't stick to one sequence, but are all over the place.

Finally, the radio keeps radonmly turning itself off in the middle of driving, or when switching off, then putting itself into "safe" mode, needing the code to unlock it.

The points where all the thin-core wire connect to the battery look brand new, and i'm wondering if it's had a problem that couldn't be fixed before it got traded in. Could the symptoms i describe above be alternator related, i have to say, that doesn't look old and caked up either... really hoping we havn't bought a lemon!!

you need to get the fault codes read. there should be someone near you with VAGCOM that will be able to help

OK, cool. I have VAG COM on my laptop and a reader cable, have read my Octy before!! Will try to find the OBD connector and do a scan.
