Vauxhall Owners Club Posted January 6, 2022 Share Posted January 6, 2022 Sounds like you have a few issues there. I would first try to programme the injector to the vehicle and then attempt to statically purge the DPF and if any better then take for a good blast to ensure all is clear Quote Link to comment Share on other sites More sharing options...
