Thanks for that Gavs, I'm sure then that would also be the case over here across the ditch...

Having cleaned the car so it was spotless, I've just driven it about 10KMs in urban traffic and returned to find the back of the car is covered in soot particles. It wasn't doing this when new. Time for a visit to the dealer on Monday.

Dang you should see my car lol... The soot has gone bonkers on my rear euro plates and my rear bumper-boot and the dealers aren't even convinced about it :|

Soot doesn't mean oil consumption though, it's just particle matter from combustion, direct injection engines naturally produce more carbon build up due to the fuel delivery. If it's oily sludge then you might have a case...

^Gavin nice bit of info

I would still like to know why direct injection engines create more soot than MP EFI but that statement instils more confidence in my car.

I noticed that I have soot on the back I my car (a very small amount, pretty much unnoticeable compared to others) but I was wondering what would be causing it. I don't have oil consumption issues (haha go the 1.2T) but I do have soot - I just thought it was running too rich or it was burning incorrectly

In warmer weather (above 30deg) the idle does go up by about 200 rpm and it's more prone to sooting up but i ruled this down to it trying to prevent pre detonation by running rich.

After the most recent cruise up the reefton (bellow 10deg) the entire exhaust was pitch black - no joke you couldn't see a single bit of silver and I was concerned to say the least. The thing is it's not oily - just black carbon powder.

Had a crank case hose and another hose changes last week. Checked the oil at first fuel fill yesterday, anx it is down to 1/3.

Of course, did I think to check how full it was upon receiving the car back? Of course not!

Sigh. Will keep monitoring...

got a call from VW saying they wont be doing an engine rebuild but instead changing my breather hose again.. they said this is a new one compared the previous breather hose change? A load of bull or does it really exist ? Also would an engine rebuild really solve the problem or is there a glimmer of hope for breather hose change in terms of oil consumption ??

I quote:

"Checked ELSA for next stage of consumption test as per TPI.
Requires crank case ventilation hose and air intake hose.
Have ordered parts and will fit when both clutch and mechatronics are replaced"

Has anybody else had to go through this step?

I don't remember seeing anybody getting these done... Am I wrong?

This appears to be legit... See my earlier post.
I hadn't heard of it before either...

Been done on my car, so far not impressed!

634km into my latest consumption test the light's come on again

... need to sort out a time to pop in. Again.

Seems to have gone from bad to worse from time to time as well, quite hard to tell what the next "step" these folks down at the dealership will do...

Sigh
