Crazyspeedfreakz Posted February 6, 2015 Report Share Posted February 6, 2015 Hi there peeps, I have a vw lupo 1.4 tdi that has a running issue Basicly the turbo kicks in at 2krpm the issue is prior to this there is no / limited power so between idle and 2k the power is massively down and its so slow its dangerous pulling out at junctions etc..I pulled 1 fault code with a vag reader which was 17964 which through looking would be the n75 valve but I think this would only affect the boost but the lupo is boosting fine..I took off the egr valve which was thick with gunk and gave it a good clean but the issue still persists Is anyone had a simular issue or able to advise on what I could do next to rectify the issue...Many thanks in advance Csf Quote Link to comment Share on other sites More sharing options...
Rich Posted February 6, 2015 Report Share Posted February 6, 2015 Have you had the belt done lately? Quote Link to comment Share on other sites More sharing options...
Crazyspeedfreakz Posted February 6, 2015 Author Report Share Posted February 6, 2015 Hi Rich, belt was done a few years back.... Although I'm planning on having the timing belt done again the next month or so when funds permit but need to get to the bottom of this problem first .... Any thoughts Quote Link to comment Share on other sites More sharing options...
Rich Posted February 6, 2015 Report Share Posted February 6, 2015 I was thinking that maybe the cam timing had been knocked out when the belt had been done.Step one, replace all vacuum hoses, use ear clips on the ends and clean all the crap out of the whole system.If you're really bored take off the inlet and clean all the crap out, egr valve too.This might actually solve it.

Crazyspeedfreakz Posted February 6, 2015 Author Report Share Posted February 6, 2015 Hi rich, thanks for you help first of all ... Cupple of things, if it was a hose issue would that not be turbo related as the turbo pulls fine but secondly and more importantly can u elaborate on "the whole system" I don't mind pulling what I can get to apart and as per op I cleaned the egr but didn't check that it was moving ??? Which I was told I should do... Quote Link to comment Share on other sites More sharing options...

Crazyspeedfreakz Posted February 9, 2015 Author Report Share Posted February 9, 2015 possible maf sensor?Yep I did think this but would it not through a eml if it was, and also wouldn't it show on the vag scan ?? Is there anyway of checking it or is the only way to replace with new ?? Many thanks Quote Link to comment Share on other sites More sharing options...
