reginaldmerritt Posted January 5, 2018 Share Posted January 5, 2018 I have a 2009 Focus 1.6 tdci Estate. I'm getting a blow off sound like a dump valve after and during acceleration. Under hard acceleration I get several blow off sounds and loss of power until I restart the car. I'm not getting engine management light come up. I brought the car just under a year ago I have already had the turbo changed, injectors changed and DPF cleaned. I brought a OBDII bluetooth Reader but I'm no where near a mechanic and looking up codes has just confussed me. See picture below. I'm not sure if the combination of codes together makes a difference. I don't understand why I'm seeing underboost and overboost codes together. I'm interested to see if anyone has any thoughts on what could be causing this issues together. Many thanks in advance. Quote Link to comment Share on other sites More sharing options...
reginaldmerritt Posted January 5, 2018 Author Share Posted January 5, 2018 I should add after clearing codes I get the codes in the picture below return and this makes no difference to the blow off sound with loss of power, and the other codes all return eventually.
