Hudster Posted September 10, 2006 Report Share Posted September 10, 2006 Hi all, My 2001 1.8T Golf IV is running with the engine warning light on the dash, and occasionally hesitates under acceleration. Just done a scan and got the following two lines up, not sure what to do about it though or how to check the DV Address 01: Engine Controller: 06A 906 032 DR Component: 1.8L R4/5VT 0002 Coding: 11500 Shop #: WSC 00000 2 Faults Found: 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 Link to comment Share on other sites More sharing options...
pritesh Posted September 12, 2006 Report Share Posted September 12, 2006 Its possible that there could be a leak on one of the hoses this you are releasing boost. Or the valve maybe sticking. I would try and source a independant specialist as the work will be much cheaper. Link to comment Share on other sites More sharing options...
sloinker Posted October 28, 2006 Report Share Posted October 28, 2006 Look for a cracked vacuum line first. MAF sensors also go bad but don't show a code but cause the lean code and misfire/ secondary air codes. Link to comment Share on other sites More sharing options...
edition30 Posted October 30, 2006 Report Share Posted October 30, 2006 its very often we find a split vac hose under the inlet manifold, cant quite remember which it is but you can hear it hissing and if you touch it the noise stops, this pipe causes no-end of running faults here are the vac pipes........taken from etka7-621 (10/2006) Link to comment Share on other sites More sharing options...
Hudster Posted October 31, 2006 Author Report Share Posted October 31, 2006 thanks - it does hiss although it's hard to pin point exactly where, I'll have another look Link to comment Share on other sites More sharing options...
