Mk3 ibiza cupra limp mode and blue smoke

[highlandcupra]

Hi, my first post, I realise these issues are covered in length and I have read them all over and over, ive just not read about them in combination, I bought a mk3 cupra AQX coded ibiza a few months ago, picked it up cheaply and not surprisingly have had problem after problem with it since, in short ive had boosting/surging/smoking and misfire issues with the car.

When I got it it was running a different fuel rail and fpr and supposedly a stage one map, my intention was to take it to stage 2 with all the neccassary supporting mods, the car never felt right but thought as I I assemble the stage 2 hardware and get it remapped these issues would be solved, not the case, ive since discovered several blown fuses, faulty maf, duff coilpacks and blocked breather system.

My remap guy informed me the so called map on it was done by some bedroom cowboy who had messed with the air/fuel and o2 sensors along with other stuff, basically should have walked away from the car.
But since ive had it ive had the valve stem seals done, new coil packs maf and oil catch can setup, ontop of that all the stage 2 stuff, ko3s fmic blueflame 2.5 dp.
Everything has been taken off and reassembled so many times due to ware and tare failures that I know eveything is on properly. Now I feel ive been over everything and the car now smokes and goes into limp mode after a very short time on boost, the car will boost to 20 psi then sharply drop off then into limp mode, plus I can see substantial blue smoke from the back. This whole proccess of things breaking and getting replaced has taken all summer and im sure to have missed out alot, but im now completely downhearted with it all, the car is going back to the remapper again but I guess what im asking here is for anything I might have missed that some one with experience might be able to see

have you plugged it in to see what its saying any fault codes

 

[highlandcupra]

Numerous times over the months, ive had 0 maf readings, short to earth codes, little to none boost readings, these issues ive sorted, but every time I sort one thing something else goes wrong, it is due to be plugged in again at the end of the week, but im kind of losing hope with it now, im guessing the smoke is probably turbo seals

turbo, stem seals, rings..........
all potential causes.
is charge pipework covered in oil inside?
is breather pipe into TIP blowing out a lot of oily fume?

 

[highlandcupra]

Its done a few miles on new stem seals, in fact its only done a few miles period, last time I had the pipes off was a few days ago and oil biuld up was minimal, I have a catch can which is vented, not into the tipbut its venting steam on occasion???

 

[ibizacupra]

if its not stem seals.. and blow by is into catch can it does seem to point to perhaps turbo....

Yeah seems to, which is a downer as it was supposed to be a low mileage one, maybe time for an upgrade, just to determine the limp mode issue, more data logging at the wknd, thanks for the replies
