RRS started smoking black smoke under heavy acceleration and reduced power but no fault lights or codes shown, RAC attended didn't even look at it just recovered it, any ideas ?
It's gone to one of their garages as I have the parts and labour warranty with them up to £750 Nanocom Evo

Yep I thought that, didn't hear any air noises and the contractor for RAC had a quick look but couldn't see anything but said most is covered by plastic covers and shrouds and RAC had told him just to recover it.
I have courtesy car cover too so all is good in the short term, Europcar isn't open tomorrow but they call someone out to meet you at your chosen time, top service so far Nanocom Evo
