high oil usage, any ideas?

[PDT]

Dom, I have a copy of your standard map and a leakdown tester.

[shark_90]

Dom, that Stock map you have is 100% stock. If the car is still black smoking (overfuelling) with that on, then you have a problem somewhere else that we need to find.

i seem to burn a lot of oil also but not as much as that.

Well I managed to find a garage that can do a leakdown test 40mile away, so at least I can rule that out on Monday. Hope it's nothing to do with the remap. I was running very high timing pull for a while, hope it isn't that whats done the damage.

hi mate sorry to hear about your oil consumption issues , you mentioned high timing pull? what map were you running to get that? and how did you get the timing pull to calm down ? do you have any logs that i can look at ? would like to compare them to my high titming pull logs before i go bang

Swapped it last night to your stock map, and its still smoking

Did some datalogging with the stock map on, Boost and fuel pump seem fine, but it  seems to have a lot of timing pull at lower RPM, and also the AFR looks lean? I wonder if the smoke on teh stock map is coming from the engine trying to richen the burn up?

[martziniuk]

Stock map should run that lean as it doesn't produce much boost, power or high EGTs.

If its running rich on the stock map Id say it was your lambda sensor as that causes overfueling.

[robdf2]

how do you work out your AFR? what blocks dod you log for it? and whay a high number and low number is?
i have a feeling mines running very lean , can you please tell me what a standard AFR and a stage 1 AFR should be please.
thanks guys

you need to log block 31, then multiply the lambda actual value by 14.7.
From what I've read on here by using the 'SEARCH' function, 2.0 tfsi are supposed to run at around 12, but thats only from what I've read......
the lowest afr I had(rich) was 9.55,highest Ive had is in teh above logs.
Might be me worth buying a new lambda sensor then

thanks for your help mate , really appreciate it

why would you want to do that? None of your logs indicate you are running rich, you are using oil at an alarming rate whilst puffing smoke out, don't you think the two go hand in hand? get the leak down test done and go from there. Why waste money on guessing.

Sorry to be blunt Dom but you may need that cash at a later date 

[heavyd]

It just seemed to make sense that black smoke = overfuelling, fuel pump  logs look ok, but I'm still running rich on a stock map. If theres too much fuel going in the cylinders, any oil in the cylinders is being washed away by all the excess fuel, so this coud cause black smoke and high oil usage issues??
Ive being phoning PDtuning for the last 3 days trying to get a leakdown test done, but no-one answers the phone!

Faulty lambda (sensor 2) brings / has brought up a dash light on mine.

I get quite a few black specs on the tailgate too

[heavyd]

Ive had the 2nd lambda sensor mapped out though, it usually is on stage 2/2+/3 remaps. I used to get the CEL light on every 3 days or so!
A few black specs would be aceptable on a remapped car, \but I'm getting them with a stock map on my car
