Happy new year everyone,
I drive a 2006 A3 2.0T 3dr with 32k on the clock. i've been getting an intermittent problem where opening the car with the remote locking doesn't seem to work. the battery in the key was changed (and the key was programmed by an Audi bloke), and it hasn't made a difference to the problem - i think it's the car and not the key as the little red LED on the key flashes every time i try and lock/unlock the car.
it usually happens after i've been driving the car. when i try and lock it as i walk away, it won't lock. it's been getting worse, so sometimes now the car won't open when i first come to it. it always opens with the key itself, and after i've used the key then straight after the remote locking will work fine.
last night i noticed that when the car wasn't locking and unlocking there was a clicking sound coming from the driver's side rear wing - dunno if this is relevant, or if it's just the petrol flap trying to unlock.
the car is an Approved Used car and has about 7 months of warranty left so i'm gonna book it into Audi to have a look at, but i was wanting a heads up as to what it could be - purely out of interest, and just in case they try and pull a fast one and say it's a wear and tear issue.
my 2005 1.6 didn't have this issue in 5 1/2 years and 70k miles, so a little unimpressed!
cheers for your help guys,
