Update - replacing the rocker cover gasket has NOT fixed the problem.
I am now £100's out of pocket and the car still has the same fault as I first reported back in July.

It's booked back in again next week.

This problem is intermittent. Just wondering could it be something leaking when the regen cycle kicks in? It doesn't do it the majority of the time, then you get a horrible smell, and smoke/fumes from under the bonnet.

It was quite embarrassing this weekend as I turned up to a posh Italian restaurant in the Oxfordshire countryside to celebrate my in-laws 60th wedding, only to have the car wafting fumes and smoke out in front of everyone, with them all asking if the car is OK.

I'm getting to the point where I am considering dropping Volvo. I realise intermittent faults are difficult to find, but I can't afford to keep throwing money at it, and not have it fixed.
