02 GT TDI 150pd juddering/loss of power @ 3000rpm

ch4chi · 31-01-2010, 01:21 AM

my 02 golf 150pd is giving me major problems, when it reaches 3000rpm it starts to judder (heavily) and throws out black smoke and wont go over 3000 rpm, i then have to change gears before any form of acceleration is possible, more recently their is sometimes a conplete loss of power, it then takes upto a few seconds (sometimes upto 30 seconds/sometimes longer) before it even accelerates normally in an idle state.

It also goes into 'limp mode' on motorways where I struggle to reach anywhere near 60mph!

I was told that it was my boost pipes, so I replaced 2 that a mechanic thought looked loose/worn but to no avail, took it for an mot yesterday and it failed on the emissions test!

Since the above, i have taken it to a VW specialist (VW trained) who hooked it upto the laptop, a tempreture sensor fault came up, which has been replaced, he also replaced my MAF with another one to see whether that was faulty, he then went to reset codes when a fault code came up

16688- injector 4 intrmittent misfire???

any idea's is it simply a case of replacing, or is there other possible trouble shooting i can do to rectify the fault??

Any help would me much appreciated

please take into consideration I am not very clued up on terminology or technically/ mechanically gifted when it comes to motors! So I apologise if I've missed anything or come across a but thick!!!

Thanks in advance for any suggestions

Welcome to TSN!

My friends 03 Golf 105 PD (??) had the same with the judder - but only when cold. Needed a new injector for cylinder 1.

I find no go after 3000 rpm anyway in my 115 PD. So keep it under that. You might also have a loose/split air hose - hence no/lack of boost. Check the hose going into the inlet manifold.
