Hi all. Just popped round to a friends to diagnose his Engline Management light on. Vagcom codes are: 17536 - Fuel Trim: Bank 1 (Mult): System too Lean P1128 - 35-00 - - 17705 - Pressure drop between turbo and throttle valve (check DV) P1297 - 35-10 - Intermittent Runs/ drives fine... Theres a fluttering around the DV area when the throttles let off. Like a pidgeon. Any one else recon its a knackered DV diaphram? Just After some confirmation before i order him a forge.
