Blowing smoke

[Chardy]

so 17,000 k's into my GTI journey and i'm blowing a bit of weed when I out the hammer down.

You can only see it at night in the car behind me's headlights, can't see it during the day.

Anyone else having this - should I be concerned?

are you sure there isn't a tdi badge somewhere on your car?

but seriously, i think you should be quite concerned. what colour smoke is it?

[Chardy]

looks white (oil burning smoke) in the headlights

Yes and nope you shouldn't be. It's normal for the GTI. Take a look at other GTI's and you will see dirty exhaust tips. There is a thread on this on golfmkv.com that goes into detail.

You're not describing the cold engine steam are you? I know it's a dumb question, but I noticed mine last night and I actually was surprised how much there was...

[jayjay]

gasket? valve seals? i mean.. this would only be if you beat the crap out of your car.. like holding it on redline when it's cold.. i mean 17xxxkm is nothing.. yeah.. could be just condensation..

how often is it? as in, is it always when you gun it? or only when the cars warming up?

If you're up your GTI, of course it's gonna blow a bit of smoke. As long as it's not plumes of blue or black smoke, which indicates mechanical failure. Same applies to all petrol vehicles (and diesel as well). Under hard acceleration, the ECU richens the fuel delivery right up to give maximum power. There'll be a little bit of unburnt fuel, hence the light bit of smoke.

just under hard acceleration and when the car is warm / hot.

i'm going to take it in to have the O2 sensor checked just incase, better to be safe than sorry.

I do drive m car hard from time to time but more in a 'wearing out the tyres' hard. I don't ever bounce it off the rev limiter.

These cars are built and designed to be driven hard and in Europe they are driven hard on a daily basis so i'm not overly concerned - just wary and thought id ask.

ill let you know how i go.

Whenever I've followed a Mk5 and they have given it a boot full I've often noticed they tend to let out a little puff.

It must just be all that raw POWAH!!!!

Black (Fuel) not white/grey (Steam/Oil)
