Hi guys, my car is 2017 500 Abarth, euro+ phase2.
I got CEL recently when car is running, code p0243 and p0034. Maybe there are some problems with turbocharger bypass valve or control circuit or turbocharger wastegate solenoid has an open or short circuit.
Since i got code, there was no apparent loss of power, but doesn't speed up smoothly like before. I've adjusted my wastegate, upgraded bypass valve to forge bov, but it's strange because there is no valve sounds after push throttle, maybe there is no pressure or no signal so it doesn't work. I also replaced the purge control valve. I still haven't solved the problem
I really don't know what the problem is, please give me some advise or recommend me a fiat mechanic around east LA who can fix it. Thanks!
