Jim 2 Posted August 5, 2008 Hi Alex.. weird one! Wondering if it could be fuelling - like the fuel filter being SUPER gunked up or the fuel pump on its last legs? Quote Share this post Link to post Share on other sites
aposegil 0 Posted August 5, 2008 well we where going to do fuel filter but gsf gave him the wrong one as for fuel pump it sounds the same as any other k-jet is there a way of testing it? as it does start up first time Quote Share this post Link to post Share on other sites
Jim 2 Posted August 5, 2008 Just had a quick flick through the Haynes for the Passat 16v hoping it might have some useful testing procedure but simply says to listen to see if you can hear the pump when turning the ignition on - and then the next step (if the supply of fuel is weak) replacing the filter! Not much use! I guess it could be any number of things - have you checked all the intake pipework, etc for air leaks? How does the car run like at full throttle - is it making all the right noises but just not going that quick, or does it run lumpy and not pull through the revs cleanly?

Toad 0 Posted August 5, 2008 Is the exhaust getting hotter than usual? Is the ignition timing ok? Quote Share this post Link to post Share on other sites

Jim 2 Posted August 5, 2008 Sounds like the timing is WAY off - possibly a blocked fuel filter is choking the car big time! I don't think you can get anything meaningful out of VAG-COM on the 9A. I'd definately get that fuel filter changed ASAP before doing anything else. Quote Share this post Link to post Share on other sites

easypops 8 Posted August 5, 2008 The cat on mine was blocked and that caused a loss of power......put a bit of pipe right through it :D Ran so much better when unblocked......it was so bad that you could hold the pipe on the back of the cat and not get burned Quote Share this post Link to post Share on other sites
Jim 2 Posted August 6, 2008 Hm yeah - thats another good one that I have heard about happening in the past... worth a look if the fuel filter doesn't help! Quote Share this post Link to post Share on other sites
