Smoke/fumes from under passenger door?

[KEVFRST]

I've 2010 3.0, today I moved my Q7 from the roadside to my drive and turned it off. Mrs used it for a 3 mile trip earlier but was cold when I moved it. After turning it off, I could smell exhaust gasses and noticed smoke/exhaust type gas coming from under the front passenger door from what looks like a vent. Never noticed this before. Should I be worried??

Hello Kev,

Pardon my ignorance, but are we talking petrol or diesel here?

If diesel it is likely to be the pre heater which tends to come on in cold weather and remain on for a while, and does emit diesel smoke and smell! after the engine is switched off. Not a problem as I see it, just a characteristic.

If it's petrol engined - worry! 

Hope this helps.

Kind regards,

Gareth.

I would totally agree with Magnet....usually an engine preheater but if you don't have that as a fitted option then I would be worried

I didn't realise it was fitted even after 2 years of ownership. 

 

3.0 diesel BTW.

 

Can sleep easier.......had me worried for a bit.

 

Thanks all.

Probably because it has been minus 5 this year which is unusual so that was enough to activate it
