  a quick reaction, fast pull, strong uphill, spacious boot. I was looking for above 2008 Mondeo td, but, reading about dpf, and only averaging 15-20 miles per day (city, bypass mostly), it's probably not a good idea.

  I'm going to look at one this afternoon with a view to parting company with the diesel corsa and migrating back to petrol.  Mainly as the price difference is quite noticeable and as I do the majority of short town runs it won't have the EGR/DPF troubles of the newer diesels.  My
• Maybe a CR-V - £5k Diesel Dilemma 28 May 2018 (Forum)
  Does the advice of don't by a diesel for school runs & shopping extend to older cars ('08-'09)? I seem to read a lot on the subject that, when you drill down, appear to be talking about newer cars fitted with a DPF (I had to look that up) so I haven't been able to make a positively direct
• Ford Focus II (2004 - 2007) - Focus 1.6,1.8,2.0 MPG 9 May 2017 (Forum)
  I'm looking to buy a 2006-ish Focus petrol (had enough of diesel DMFs,EGRs,DPFs etc!) and assumed the 1.6 would be the most economical. However a few forum searchs show many people are disappointed with their 1.6 economy - never reaching the 40mpg figure. I know these figures are a guideline

  problems on the 2008-2011 1.6 TDCi facelift model but I am trying to check if there have been problems with those model years as I understand Ford improved the oil supply pipes for 2008+ model year I would buy a 90bhp model hopefully without the DPF if the turbo gets a clean bill of health
