Do you know if your OBDII port / Diagnostics still work fine?
I've installed many stereos in VAG cars and there is a wire called K-line in the standard ISO connectors that you need to be careful of when connecting a aftermarket unit.
Basically this is a wire that allows you to make changes and stuff to your stereo using diagnostic software such as Vag-com. This is feature is lost when a aftermarket stereo is put in, so you need to make sure that no wire from the new headunit is actually connected to, as it is known to do some damage if there is - might be related to this somehow?!

thanks pal, well i have simply put my new head unit in, bought a cable adapter thing from halfords plugged it in and its working fine, only wires i have plugged in are the 2 ones that require the unit to have power
only thing that seems to be wrong with the car is my alarm, this k-wire is this connected to the old stereo?

Your old Gamma Tape / CD Deck will be connected to this K-line.
This wire won't be something you plug in like the power ones, its already on the harness so you need to make sure no wire on the aftermarket adaptor you bought connects to the pin on the harness.
Have a look at this:

It says which pin in the car's harness is the K-Line.
