An update for anyone that is interested regarding the van, the garage has been very helpful as the master Tech has been looking at the vehicle and carrying out the work. They have fixed quite a lot of things that he found wrong on the vehicle, mirror glass not heating up, squeezing from aux belt, rear spring seats worn with springs not aligned, dust cover missing on both front shocks - even though they had already replaced these, exposed wire on fuel temperature sensor.
They also changed the Dual Mass Flywheel as they found that it was excessively worn when they removed the gearbox for inspection.
The only remaining issue on the van is on the DSG gearbox. When manual mode is selected or plus and minus and accelerating. As the gearbox changes gear there is a harsh or notchi gear change. My understanding was that it should be a seamless smooth gear change. I have test driven other vans they had and they’re all very smooth in manual mode so I’ll be carrying out a long test drive and the van will probably be going back for the 4th time, but the service department have been very helpful probably because I raise the issue with VW head office customer care.
If anyone else has got a DSG van, would you mind accelerating from a low speed and changing gears with the manual mode at higher RPM around 3k and seeing if the notchiness is there with you as well?
