Vauxhall Owners Club Posted March 15, 2021 Share Posted March 15, 2021 It sounds like a turbo issue....is there a whistling/chuffing noise when under load (e.g. turbo boost hoses split?) it may be an injector fault but I would check for split hoses first. Not sure why the OBD port is not communicating though Quote Link to comment Share on other sites More sharing options...
Rich179 Posted March 15, 2021 Author Share Posted March 15, 2021 Doing my head in mate. Been told today that it could be a ecu fault regarding unable to use diagnostic readers and pedal test. Quote Link to comment Share on other sites More sharing options...

Vauxhall Owners Club Posted March 16, 2021 Share Posted March 16, 2021 It could be the EGR and worth blanking off to be on the safe side Also, check the turbo hoses to be sure they are not holed Quote Link to comment Share on other sites More sharing options...
Rich179 Posted March 16, 2021 Author Share Posted March 16, 2021 But would the egr valve cause my no communication with any code reader. Also why the pedal test won't work Quote Link to comment Share on other sites More sharing options...
