Hi All,
This Passat judders excessively when put under load usually between 2000 - 3000 rpm. You can still feel a slight juddering at very low revs (even when reversing at very slow speed).
The VW Dealership has fitted a new set of injectors (twice apparently) and a local garage has fitted a new DMF and a new fuel pump in the tank.The tandem pump pressures are okay.
The only thing I see wrong is that it appears to erratically miss some pre-injection pulses at random. I've enclosed a Pico capture when the vehicle was at its worst. I don't really know why this is happening and I would really appreciate all the help I can get at this stage. Thanks you in advance.
