I have a seat ibiza cr tdi 1.6 2014 model with 90hp and 230nm with 127.000 km . Sometimes the car is so powerfull that the esp light comes on at second gear easily at some roads at my neiborhoud and at 3rd gear i clearly feel the torgue from 1500 rpm-3000rpm. Other times , at the same roads the 2nd gear doesnt have the power for the esp light to come on and at the third gear the torgue is more noticable from 2100-3000rpm... I have checked with vcds... no fault... map exelent with 800+ both reguested and actual , map excelent with 1,4 bar with reall boost following the reguested, commonrail exelent with nice pressure up to 1600 bar and injectors seem fine too (dont know how to check them with vcds but since everything else is ok with my car a suspect they work ok?).... I suspect that it has to do with the dpf? maybe before regen there is exhaust restriction and after not without me realising ? My dpf light has never light up ofcurse. Maybe the diesel quality? My problem , is not really a problem no bad fuel mileage ( i get from 5.3 L/100 km with economy driving 120 km/h-130km/h with cruise control to 7.0 l/100km with extreme driving) no difficult startups no hesitation no jerking no nothing... and the engine sounds as smooth as f@@k... but i want the power to be deliver nice and strong everytime with the same way every time... i dont like that performance up and down....and i am sure about what i tell you i notice since i know the car and how it works so good that even the slightest alternation at its performance is notisable to me. Anyone that has an idea what to inspect?
