Hi all, First post here for me. I'm having a spot of bother with my Focus. Hopefully someone may have some thoughts, but if not then no worries - it's good to share! 2009 Focus 1.6 TDCi 73,000 miles I've recently started getting an intermittent 'engine malfunction' message on the trip display a few seconds after start-up, but no accompanying warning lamp on the speedo. Engine sounds and runs fine, as best I can tell, with no noticeable reduction in power. Took the car to my local independent garage, who plugged in the diagnostic laptop and reported a DPF regeneration failure. Advised that I take the car for a 30 minute blast on the nearest motorway, getting the revs up nice and high, but having now completed a couple trips where I've pushed the car more than usual, the warning message is still appearing (but still no engine warning lamp). Now, I know all about the principles of driving a DPF diesel, and fortunately for me I'm not a town driver. I do a 40 mile journey twice a day, five days a week, and at least 20 minutes of each journey is at 70mph (revs around 2,300 in top gear). I've been doing this commute since I bought the car from new, so it strikes me as odd that I would need to assist with DPF regeneration after 3 1/2 years of long trips, with no warning messages appearing until now. Unless, of course, the DPF unit is throwing in the towel... I've read conflicting reports about DPF life; some claim they need replacing around the 75,000-100,000 mark, others claim they don't need replacing at all if the driving style is appropriate. I'll be giving the car another good run tonight and if the message still appears tomorrow then I guess it's back to the garage for a closer inspection. Will report back any findings in due course, but any thoughts welcome in the meantime. Cheers.
