The fuel filter did not solve the problem unfortunately, i tested the MAF sensor by unplugging it and going on a short drive, the car drove fine with no juddering, so i bought a new MAF and installed it, took it out and the problem persisted even with the new MAF! Iv just posted another thread about my car which is now more urgent, iv has terrible luck with it. I think there is something horribly wrong with my electronics somewhere also it's a 110bhp VE Thanks for the replies

Hi everyone, Iv had a massive issue with my 2000 a4 b5 avant 1.9tdi recently! it started off with occasionally i would need to turn the key back and forth a couple times till the glow plug light came on and it would start, this deteriorated to being sat there for almost an hour turning the ignition on and off until the glow plug light fired and it would start fine. The engine always cranks but will not start without the glow plug light coming on. Now the light never comes on and its been sat in the drive for too long. Iv looked at the main ECU relay 219 which many people believed could be the source of the issue but that is fine, iv even got a spare one and the problem is still there. Another fault which has my symptoms is the camshaft position sensor or crank position sensor i cant remember which, however there is no engine light or codes coming up on my code reader. One code which did appear was something to do with missing the CAN bus signal. My theory is that its ecu related and there may be some faulty wiring or connections or relay somewhere but im at my wits end with it! any suggestions very much appreciated thanks

Cheers, and thanks for the reply. As you say it sounds a lot like fuel starvation, I'll smack that new filter in and see how I go from there

Hi everyone, Iv just bought a W reg A4 avant 1.9tdi, I must say the car is great, however i have had an issue with the car juddering when I put my foot down hard enough. If i accelerate gradually there is no problem at all, it revs beautifully and can get to a decent speed. When I, for example, accelerate hard out of a roundabout in a lower gear it can judder violently, this stops as soon as i lay off the throttle slightly but it returns whenever I quickly put my foot hard down on the accelerator. Iv also noticed a rough/ lumpy tick over that is intermittent. Iv bought a new fuel filter and a diesel system cleaner that I will use in the coming days. Just wondering if any of you lot might know cause of this issue? many Thanks!!
