• VW Golf 1.9 tdi / 1.6 petrol approx 03 plate - Diesel or Petrol 11 Feb 2011 (Forum)
  i used to own a Mazda5 diesel which I have had to get rid of due to change in jobs and lower milage may run me into DPF problems (although I had some minor ones before having read on this i have heard its a living nightmare on lower mileages) now having driven diesels for the past 15 years due to high mileage covered I think its fair to say i have an affection for them, now although my mileage wont justify it as an economical option i dont feel as comf***able in a petrol, what i wanted to know is if i purchase a non DPF diesel on an average ,mileage of approx 7000-8000 miles (mainly local driving) and get a 6 month oil change between services taking the usual precautions of leting it run idle a few minutes after journey completed etc should i avoid any major problems?

• ford focus - Particles, Catalitic converters, DPF's, Diesel??? 9 Jul 2011 (Forum)
  If manufacturers are so comitted to low emissions how is it that I cannot buy a Ford Focus without air con ( uses 8% more fuel) and told by most enonomy drivers to turn off and it adds £500 to car. I have managed since 03 with a non air con fiesta if I get hot I open the window. The DPF's have an effect on fuel consumption so does Catalytic converters. The addition of the stop start system must put more stress on the battery and will most probably give it a shorter life span. Thus causing more polution in manufacturing a replacement.
• Review - Punto van Mk2b 1.3 Multijet (pre DPF) 9 Apr 2010 (Forum)
  It`s done a 79mpg return over 120 miles at around 55mph and really can`t be forced below 60mpg for any length of time however it`s driven. Camchain, hydraulic tappets, galvanized..pre DPF - all plus points. Build faults -the rear door lock not seated properly - two minutes to fix. Possible design faults?  door check strap on drivers door wore after only 15,000 miles leading to a clicking sound on opening.
• SEAT Ibiza - Super Quiet Exhaust 12 Apr 2023 (Forum)
  I have got a 2012 1.2 tdi Seat Ibiza and have gone to great lengths to make it loud. As of this afternoon it now has a hornet exhaust back box, dpf delete and decat so it is virtually straight through. Yet, it still remains very quiet. What the hell can I do to make it loud? Don’t mind doing some redneck/dodgy stuff to get there I just want a nicer sound
