Not sure what's going on here, but my Signum cdti 150 keeps smoking quite badly.
I had to pick the mother in law up from Asda the other day, and as I pulled up on the car park, plumes of diesel smoke were rising up from underneath (around the back of the engine/cat area) and to be fair, it was a tad embarrassing.
It also has days where smoke billows out from under the plastic engine cover, which on further inspection, is coming from the recess around the swirl flap bar, which currently is broke off, and lay on its side.
It smoked again yesterday quite heavily from this area, and filled the inside of the car via the vents with diesel fumes, which considering my 5 month old baby was sat in the back,, was not a good thing.
I have now pulled out the swirl bar, and am looking to do the cheap repair, but have no idea why the car is throwing all of this smoke out.
Oh, and at its worst yesterday, I pulled away after stopping to check, and left a cloud of smoke behind via the exhaust.
Any ideas guys?
Cheers,
S.
