Hi bud, to check if your maf is faulty, unplug it and see if the idle is any better, if it idle ok with the maf unplugged you need to replace it. The k&n has probably caused it to go

thanks for that mate,if it is that it will do it again i suppose if i have to get a new one. someone said to me not to do it coz of oil residue getting stuck to the maf, will try that tommorow,still gonna fit the d/v though hope that goes ok thanks again mate....

I had a k&n in mine didn't cause any issues, you could clean it first and see how it goes. It might be worth getting it checked via vagcom, might have other faults on it
