Hi folks please can you help
I have a Qashqai 1.5dci Diesel 2016
I put a redex DPF cleaner into my tank. Reason for this the vehicle was powerless going up hills no engine light on. Thinking it was the DPF I added a Redex DPF cleaner which immediately brought the engine light on.
Took to garage and had the DPF sensor replaced. Engine light erased. On road test the EM light came back on.
Worried because I should have added the Redex to a full tank not 1/2 Tank.
ANY HELP WOULD BE GREAT
