Hi mate,
I have looked into this and there are quite a few things it could be be. The maf sensor seems to be quite a regular fault. Timing can sometimes be out and even little air leaks.

Hopefully someone with a bit more experience on here can give you some ideas on how to check.

Cheers
Tim

Temp gauges tend to jump around a bit and are usually solved by replacing the temp sensor. any good volkswagen garage would change it over for no more than £35 supplied and fitted. my temp gauge would cut out completely sometimes, had the temp sensor replaced and is good as new. don't know about your idling problem though, sorry

I had a similar problem, turned out the fuse for my air-con had blown.  You find it under the battery cover, replaced it and all was well again.

cheers for all the advise guys.

going to get myself a new maf this weekend, any idea how much i will be looking to pay? is it worth going to VW or just a norm car place

VW or motor factors.  Make sure you get the genuine one though (think its a Bosch).

Price is around £70 on an exchange basis i believe
