Default 2004 A4 1.8TQ Constant light bulb replacement

I bought my car 2 years ago and I've had to replace 8 bulbs already.
2 x Front right signal
1 x Front left signal
1 x License plate light
1 x left tail light
1 x right tail light
2 x brake lights

Is there something wrong with my electrical system or is this normal with Audi's? They don't intermittently go on and off and I've checked for condensation and I only see a hint of it in my rear left tail light.

my car hasn't been that bad but B6's are known for the tail lights to burn quickly..
Dont forget that the tail lights are always on.. maybe if u could somehow disable that feature the bulbs would last longer.

My signals are a pain too, I had my front right burn out 2 months apart and now my rear fog is burnt out but sometimes it comes back on, so weird.

a little tip.. when changing your tail lights. Change all of them.. that way you wont be changing bulbs every few months....

Does it come back if you try to tap on it ?

Looks like it's a problem of rust on the circuit board ( see pic), you can try to see behind the grey plate there is green board, try to notice any rust marks. i'm having that problem with the left brake light, i did i search on internet and the only solution is to replace the whole circuit or to avoid DIY bying a new assembled rear light

I didn't notice any rust, but this is interesting I'm going to take it apart and check tomorrow.
