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 :stupid:

Got you.  Awesome never added the Map for getting rid of the light on my 2+ APR map, even after I had the decat. Gits.

I never got the light before the decat.  I replaced the cat for MOT/TUV and still get the light, vcds says sensor 2 lambda. Overheated I think.

Your logs show you are running a lot leaner with stock map than the remap. I have read posts on the k03 that stock on that  is about 10.5:1 @ WOT Redline (I cannot check this without loading stock map on), I don't know about k04.

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!
Are you running a catch can?

No. Ive thought about getting one, but wast sure if they were worth the money or not. There seem to be pros and cons about them, Ive also read that if you use decent oil and fuel theres no need for one :confused:

I wouldn't be paying any attention to the maps if your using these amounts of oil,running rich isn't going to have an affect on oil usage it's either turbo,valve stem seals or piston rings

Agree with the above,know mine is a soot chucker but mine was splattering the back end of the car with a lot of  black speckales when my turbo went,think I would get that checked first

Dom, take the car for a good hard drive and get it nice and hot. Let it sit at idle for about 1-2 mins then rev it hard in neutral, see if you get a cloud from the exhaust, if so it could point to turbo oil seals.

I still cant 100% rule out a breather issue either. I have had cars in that use a lot less oil than yours but still have oil consumption problems and they smoke a fair amount, on the test drive in yours today thete wasnt much smoke at all.

Brill news! At least you don't have to strip the car down and it shouldn't be too expensive.

I phoned dubtek and they haven't got any bsh pcv kits in stock, but I'm going to get one when they're in stock. I didn't get any smoke on the way to work either, sods law!

I did that idle test thing today. It did make a cloud, but it was black smoke that wasn't oily,  still no blue or White smoke. Going to wait if the bsh pcv fix makes any difference before I spend big££££s.
It was throwing some nice clouds out on the way back from shark hq today again!

Lots of cups of teas, a reprogrammed sts, hospitality, friendly banter, and Ben reckons its only unburnt fuel -  buy a PCV fix kit, doesnt think its the turbo, same concluson as Dave at PDT really  :popcornsoda:
