smelly boost ??

[Shark]

Hi there,

I have noticed a smell tonight that comes into the car when the secondary turbo is running.

I can;t really describe the smell very well, it;s not petrol, and it;s not rubber, I could only describe it as smelling like burnt air :rolleyes:

Could this be anything to do with the coolant change I did at the weekend?  only started today, and it has been driven since the change but I topped it up again (admittedly in the dark) last night before coming home from work...

or is this a symptom of a blocked cat?  (which would be a handy excuse to replace the whole exhaust system.
