ERB

I used SMUTTS solution and it worked for a while, probably because I do lots of motorway driving. I did a Terraclean and that helped for a bit. I've started to use better fuel and that seems to help. It recently returned (after a fill up of supermarket fuel!) and I couldn't clear the fault long enough to do a burn on the motorway. So this time I decided bite the bullet and clean out the EGR.

Before the clean, I had intermittent white smoke, and sporadic rattling and vibration in the engine, then LIMP mode (with "Check VSC" and warning lights displayed). After I cleaned it, the car was back up to power and... best of all... I didn't notice the engine. I used these videos to work out how:
