Smoke/Steam out of exhaust? Normal?

[kman86]

Just after some advice for the following.

First, Car details: Mk6 118 TSI, 20,000km

Problem: Upon hard acceleration (e.g. taking off from lights or merging into a highway using an onramp) there is a noticeable cloud behind the car as the Turbo kicks in. This is very noticeable when there is a car behind me (I can see the cloud in their headlights). There is also a slight fogging of the rear window (assuming the outside)

I can’t see that there is any colour to the smoke/steam but it seems to dissipate rather quickly as would steam out of an exhaust on a cold morning. I live in Canberra was thinking it may have been the cold of winter causing this but I have also seen it happen in Sydney and in Canberra in summer.

I am wondering what might be causing this and wondering if it is normal or something I should be taking this to a dealer about?

Any advice/ thoughts welcome.
Cheers.

Well... steam and smoke are two different things really. All exhaust pipes put out both though - I mean, that's their job.

The question is really "how much smoke is normal". Hard to quantify on interwebs without pictures or video. If you're worried, see your dealer.

Kman86,

If you are keen to meet up sometime, I can follow you when you put the boot in for a 'snif'. I regularly see GTI's / R's putting out a fair bit of soot under hard acceleration.


FYI - I drive about 25kms to Civic each day and even on arrival at a parking spot, the car is still putting out a little bit of 'steam' in this cold weather. This steam only really exists at idle, no other revs.

Hope this helps
Stu

Whenever I turn the air conditioning on, I get this air stuff blowing out of the vents. Is this normal?

When you say 'air stuff' do you mean

78.084% Nitrogen
20.9476% Oxygen
0.934% Argon
0.0314% Carbon Dioxide
0.001818% Neon
0.0002% Methane
0.000524% Helium

Yes, it's normal.

I too have noticed this a couple of times. I just figured that, as I usually drive like a nanna, on the rare occasion that I floor it I am cleaning out built up crap. (sorry for the lack of technical mechanic-type language)

A few weeks ago I noticed it while accelerating hard onto a freeway onramp. I floored it a couple more times on that trip and things improved. The engine ran well.

I don't know what caused it- it looked like blue smoke from the exhaust, but have had my car serviced since ant the guys at Golfwagen tell me that the engine is good.

I'm not going to worry about it.

Oh comon, is it really necessary?

Black smoke is the soot which gets dislodged with additional air pressure through the exhaust. Clearing out the cobwebs as I like to think. You see it every now and then on many cars that have not had the engine taken up higher in the rev range and when they do, it expunges some of this.

Blue smoke is very different though - generally oil getting through the piston rings, being burnt. Doubt it was blue as this is only on far older vehicles with very worn engines...

That said, my WRX I had in 2000 (brand new) would put out blue smoke every once in a while. The engine was inspected and rebuilt as the 'piston rings had lined up' and every now and then enough oil would get past and accumulate (engine warmed up, idling for at least 3 minutes) to then cause a dump of blue smoke on a blast of the accelerator.

i also see some smoke from the exhaust during WOT... somehow prefer it to spit fire, popping and crackling instead.

anyone know how to get the GTI to spit fire?

A lot of the smoke under hard acceleration on turbo car is the fact that the ECU runs the engine rich at WOT.

Remove your cat, and start going through the upgrade stages.

Fab_R has said that people following him has said his car has shot flames outta his exhaust pipe - he has the full APR Golf R TBE with its motorsports cat...

I'm running on APR downpipe (100cell cat) and Akra cat back + Bluefin State 2... i may need to get a friend to follow behind me to check then..:p

or stick a marsmallow at the back and see it it gets burnt..

What is WOT? (Not trying to be funny... I just don't know).
