Black smoke

[who-sijones]

Hi all.
I've not had my car long and today when driving it hardish there was black smoke coming out the exhaust (according to my gf driving behind.)
I put my foot down and each time she said she could see the smoke, but it was worse the first time.

I looked in the engine bay and I noticed the intake was really loose and it just came off. Could this be the issue? The car seems to run fine, but I've not had it long enough to know if its normally better.

Thanks in advance.
Si

No, this won’t be causing the issue - the cone in your picture is right at the front of the system, before any sensors or metering.

Could be your DPF regenerating...

Thanks for your reply, it's an s3 though so no dpf.

I've scanned the car and there's no fault codes. I'm not really sure what it could, at least it's black and not white or blue.

It woulds help if you put the spec in your sig.....like is it a diesel or petrol ?

Oh right, well black smoke is running rich, blue smoke is oil and white is steam

pcv can cause black smoke.

Has the car been remapped as the increase in fuelling can cause this?

Also it depends how much black smoke as I have known Mk 5 GTis give a little puff of black smoke when revved even when standard.

I was told it's standard, there's no visible mods on it at least.

I've got a whistle in sports mode, I assume that's from the intake not connecting properly.

I took it out for a normal drive and there was nothing there at all, revved it on idle and still nothing

Click your name at the top of the page RHS then click signature
Maybe if the car had been standing one of the injectors just dribbled a load of fuel in to the bore/pipe which has no burnt off. any way if its cleared and no fault code then i wouldn't worry

I suspect it was just the intake being of, it has a huge amount of air intake when driving & of course any disruption in this supply will cause issues.

Yeh! Make sure the S3 is a petrol Paddy

So I've fitted the new induction kit and there's smoke, so it either needed a blast or it was the intake.

Ah well worry over and time to enjoy it.
