Car is a 2001 mk3 ibiza cupra 1.8T
Alright guys, hoping you can help me with some problems as I'm scratching my head!
First main problem is recently just went from standard to stage 2 in the past month. Full milltek turbo back with sports cat down pipe, TIP, n249 bypass (still plugged in) front mount, k03s. Stage 2 mapped ecu, air filter, 007 with yellow spring.
The problem being it was great for the first week or two of having the map, after that things have gone downhill. Since going stage 2, on my way to work I drive 5 miles down a hill so coast in gear most of the way and every time a blip on the downshift for the last hair pin I get a puff of bluesmoke from the exhaust. Its got slowly worse, now if you drive off boost for 10 mins then sit with engine running it starts smoking. It only gets worse. However a good blast will clear it for a while. I drive most of the way to work and back off boost so its more of a regular occurance. It never smokes on boost, never smokes on over run. Just seems to be like a build up, have been advised to fit a catch tank so thats on the list.
Next problem is a boost problem. It drove amazing when it first had the map, but its slowly deteriorated. When warm it really struggles to boost to 1.5 bar as normal. you put your foot down and it just boosts to 5 psi (actuator pressure). However if you quickly let off and stamp on the throttle again it boosts fine. Again the hotter the car gets the worse it gets. When cold its fine but if your on and off the throttle alot it just goes to 5 psi. You have to pootle along off boost for 10 mins before itl boost again. Had a N75 open circuit fault code on vag com. Changed it and no difference. However when I get home from work I popped the bonnet and the N75 was clicking away quite fast but irregularly.
However as said it doesnt seem like a boost leak as it boosts great when cold. Checked vac pipes etc and no leaks. I replaced them a month ago.
Will be doing another fault code read tonight, did a boost log and the requested vs actual was great on the log following very closely an no signs of leak.
Any help appreciated guys I'm at a wits end here!
