Hi there new to the forum and need some advice, currently on low revs and and motorway driving backing off the accelerator I get puffs of smoke from exhausts, blip the throttle again and it disappears, any advice or known issues?

FON

Now the advice - don't use your phone while driving

Was it black or white smoke?

Welcome and FON.
Black smoke = fuel
White smoke = water
Blue smoke = oil

Make a choice and let us know.

What colour is the smoke

errrrr, what colour was the smoke??

It's black smoke, could this be some seals that have gone?

is the car running ok apart from the smoke?
where in the world is thee??

Yes runs fine apart from this. I'm in the north east England area

Best thing to start with is to check your codes with VCDS or something. Sounds like a fueling issue, but there's a lot of sensors and other things that can cause that so to pin it down you'll have to check first if the ECU has fault codes stored in it.

Im near Newcastle and have VCDS if you need it.

^^What JC said. I'm betting on swiss cheese intercoolers or weak MAFs, or both.
