Hi please can someone help me. I haberdashery Honda Accord 62 model. Last Tuesday DPF regeneration message appeared on car dashboard (this message shortly changed into check system with smoke kind of sign and ! mark). I took my car on the motorway and drove around 30 miles continously in 4th gear with 60m/hr speed. But it is not going away. I have also noticed that since the message has appeared my cruise control has stopped working and also the gear up/down sign indication has also stopped working. Can anyone tell me please is it due to DPF need cleaning? I am taking my car to the garage but would like to get an advise.
