me cars has been running sweet until a week ago, i took it out for a drive last sunday and gave it some beans and could smell a really eggy smell and the car just didnt feel right. Its been popping and banging from the exhaust loads too which i've never really had before. I VAGCOM'd it and no errors at all, but it just doesnt feel right, the top end isnt what it used to be which suggests the maf is on its way out again. Any other ideas or what to look for on vagcom?
