Same here, I'm beginning to suspect the DPF more and more though because I've done quite a lot of short journeys over xmas and it's been an absolute nightmare! Ran a forced regen through VCDS and it was great for a few days but then back to normal and now the bloody DPF light has come on for the first time in ages! 20 mile run down the motorway didn't clear it this morning so looks like I'm going to have to force it tonight again!
Back to my normal motorway driving this week though so will hopefully get better.
Seriously though, the whole DPF design and concept on this car is completely flawed! I think VAG should be reported to VOSA for it.
