2010 Ford KA problem with exhaust gases into car

Never heard of any faults like that so far ,better get it into dealers for checking under warranty .

Sounds like there is a leak coming from the manifold for the exhaust, seals might need renewed or there could be a hole.
When the car is running hold your hand over the end of the exhaust while getting a friend to check under the hood and you should be able to feel exhaust pulses coming out of the faulty area.

check your breather pipes that happened to my bmw and i change them and no fumes came in to the car after if thats any help to you.

Hi Guys, I recently have had this problem and looking throught the posted answers I was starting to get a bit worried. If your issue is the same as mine then there is a quick and free fix.
Look at your dipstick. Is it seated correctly?
Mine was sat up about an inch and a half. I dont know if it had vibrated loose or if I hadnt replaced it properly after checking the oil last time, but pushing it firmly back into place has fixed the 'fumes' smell in the KA.
Coincidentally I have also been getting poor MPG for a while, it seems to have normalised this also.
Hope this helps someone :)
