As an update on the regen...
Local mechanic said first attempt failed, second was successful and he also did a third one. Soot level was at 34 before and close to zero after.
Cleared all codes, said there was a few various module ones, radio, door module etc.
Drove it away fine, as normal. 6 miles later TPMS, TCS and SCBS lights on and check engine again...
He is going to look at it again tomorrow.
(BG244 ordered Anchorman)
EDIT: Another 6 miles and all lights have gone out again!!
