Disabling Audi TT 225 immobiliser

[__B3NNY__]

Is it possible to do via Vag-com? My friend has a problem with the immobiliser on his TT and it wont allow the car to start, i was wondering if its possible to disable short term until the problem is fixed?

I dont mind replys in PM or i can add you via MSN etc... as its proberly not somthing that should be broadcasted on the net.

Thanks.

Why has immboliser kicked in?

Im not sure he just said that the car wont start because the immobiliser wont switch off, i havent been to see him yet to give the car a scan to see what faults are logged.

You can't do it with Vagcom, but you can interrogate the immo ECU to find out why (or is it the clocks...)

anyway, a fault code scan will tell you what's up with it

Cheers, ill more than likly be scanning it this weekend.

I was just going to try and disable it so at least he can drive it until the problem was properly fixed.

Tried all the spare keys?

You think it could be that the main key has un-synchronized itself?

Thats 1st thing to check if all keys are still functioning

Ok, just spoken to my mate whos already had it plugged in and apprently its the transponder that had gone? Hes now saying that the keys need to be re-programmed, is this somthing im able to do via vag-com i think ive read somwhere that its possible but he needs to get a certain number from the dealer, correct?

What about the other keys, do they still work? Not sure, think its a pin number, work shop no (Check the stickies, should state whats needed).

Keys don't loose their adaptation, neither is it likely that the transponder in the key is faulty. There are a couple of known issues, starting with the reader coil wiring and connectors which is a very common issue. these things are not hard to diagnose, start with checking the instrument cluster for fault codes and check the measuring value blocks.

If you could disable with vag-com it would be a major security issue.

Sounds like a dealer issue if there is a real problem with the key.

came across this today, its the first tiem I have heard of anyone making a DIY/ebay key work without going to a dealer.
