Hi all I've owned my a4 for around 8 years now and she's been a pleasure to own even prompting me to stay audi just recently purchasing an a6 on a 60 plate as need more space for the growing kids. I've recently had some electrical gremlins occur on my a4 consisting of random doors not unlocking then will unlock but drivers won't lock at all. I can hear the lock unlocking when pressing fob but nothing when locking and indicators don't blink on locking. Now I know this may be comfort module but what else may it be. I also have a fault with speedo it will work for about ten mins of driving then stops registering speed rev limiter still works but weirdly fuel gauge starts to rise then will revert to normal upon parking up and leaving until need to use the car again. Any help appreciated thanks
