Hi, Ive not had my Antara very long and today the dreaded DPF light came on. I don't have an onboard computer so how do I tell when a regeneration is complete? The manual says do not turn the ignition off during cleaning ! How many miles do I have to drive? This is all very scary for me! I was in a bit of a panic when the light started flashing whilst I was stuck in crawling traffic - I dug the book out of the glove compartment to look it up and was horrified to read that I must start the cleaning process immediately to avoid engine damage. I was stuck in traffic and not able to get to any motorways for miles.
