I let them do the software fix for the emissions a month ago when i had VW Touran serviced. Boy do I regret that.
The next week the diesel particle filter warnin light came on for the first time ever (had car three years). Then next day engine warning came on. AA came and ran diagnostics, fixed it by forcing a regeneration on the filter. Told me to run it on motorway in fourth gear and get revs up past 3krpm for half an hour.
Did that and its happened again and now the bastard DPF won't regenerate (had AA out again).
I just know I'm now in for a battle and a possible £1600 bill for new filter. I also now know this is a known thing and the software fix increases soot by double - hence my problem.

Heads up VW drivers and don't have the software update!!
I'm a city driver and this is now a totally unsuitable vehicle - I hardly ever go on motorways.
I'm never having a diesel again.
