Black soot

[bigaxe]

followed my gti the other day and noticed a heap of black smoke every time car accelerated away from a standstill at a red light or round about , car also has alot of black soot on rear bumper and boot from new. dealer is going to replace injectors on monday, had to order them in, they said they put a camera through spark plug hole and could see them dripping. car is 5 months old with 6000 ks on it

I see this all the time with the golf R and Sirocco R when they pull away so I don't think it's a fault, maybe its just how they are designed - run rich on take off to prevent pinging???

Black soot

Yeah I've even seen a TSI Tiguan doing that and a few Golf GTI's.

Black soot

Yeah, rich down low and too lean up top.

Black soot

Get the breather hose replaced at VW... Stops it chewing oil as well.

This soot is killing me at the moment, its hard to keep the hatch clean, even after 1 hr driving after cleaning, its gone all sooty...

VW told me its "normal"

ARRG!

[nomadx38]

NOPE NOT NORMAL!

The black smoke (unburnt fuel) IS normal for these high performance engines as they run rich on take off (look at a Golf or Sirocco R). The oil specs on the back are NOT. This has to do with the fact that oil is going straight past the piston rings (or through the intake) and going straight out the exhaust in a liquid form, its not even burning it!

Just run your fingers along the inside of the exhaust tip. Either way you will get black stuff but pure carbon looks and feels like black chalk, its a powder - if there is oil mixed in with the carbon you will feel it, it's like black slime.

Knowing these motors you probably just have ridiculously high oil consumption like the rest...

Welcome to GTI ownership. Bain of my existence! Especially with a white car.......

That is right, im getting a little over 1L/1000km, but was getting much higher before the ventilation pipe change.

My consumption test starts 21st May. Watch my car use no oil during that test for some reason.

What oil you using? It appears that does make a big difference

[Zakarados]

running stock castrol oil. I was going to change it at 7500km, but they want to do a consumption test, so I will wait for those results. Oil and Filter waiting at home.

Was told today that you get more soot on the back if you drive like Miss Daisy as it doesn't get a chance to get blown away. Cause the cars are meant to be driven hard, if you do push them a little more then the soot should be less

I find that the harder I push, the bigger the chunks.

had the injectors replaced on monday, followed it home no black smoke washed car on tuesday, No black soot on rear of car and it has been driven all week about 25ks a day, soot would previously appear after about a 10k drive. Soot would leave a dusty residue on your finger when you wipe the back of car definately not oily. Soot appeared on rear of car from the first day we picked it up, and yes it does use oil, so far 3l at 6000ks

No surprise really. It's not the first time VW have had issues with fuel injectors, on diesel or petrol.
