2013 Volvo v70 d5 twin turbo hesitating
Hi sorry if I’m posting in the wrong place I’m a newbie. I’ve dknt lots of reading regarding my issue but still haven’t had any look in fixing. My Volvo is a 2013 v70 215hp but it feels like it’s just the little turbo working as the revs get to 3k and don’t want to go any more. I can happily get to 70 changing low down the revs I have scanned it and only found one fault code p029900 a underboost fault
I have tried a lot of sensors as my mrs has a XC60 same engine but to no avail. I’ve tried airflow meter both map sensors the 2 solenoids at the back by the turbos checked the boost pipes and vac pipes as much as I can. I just don’t know where to go next . I can get pics of live data but they don’t mean anything to me.? I would lpve some advise before I book it in at Volvo and they charge me £130+ per hour! Thanks in advanced
