• Peugeot 306 - A small list of problems... 6 Sep 2010 (Forum)
  After a little while or a quick blip of the throttle it will clear its self and return to the normal loud diesel crack.  when i turn off the engine i can turn off the ignition remove the key and the engine will continue to run for a few seconds. On a short trip the car wont be affected as much. i am thinking prehaps fuel pump not shutting off fuel or something to do with the idle?
• Volvo XC90 (2002 - ) - I'm getting used to it! 9 Feb 2010 (Forum)
  I am slowly getting to grips with it and in fact most of the issues I now have with it are down to the poor preparation by the supplying Volvo dealer. Like all diesel automatics, it need to wake up and stretch in the morning and the fuel consumption is dreadful at that time and also stuck in traffic and city streets at any time. You can't quiet see the fuel gauge drop but the average on the trip meter certainly does.

• Indestructable Peugeot 309 22 Sep 2006 (Forum)
  Even allowing for it's 5 percent overeading odometer, fuel consumption works out to 51 mpg. The car is also used as an automotive experiment. Apart from safety checks/annual MOT test, it never misses a beat despite the 15,000 to 18,000 miles annual mileage.

• A quandary, third car or not? 25 May 2018 (Forum)
  But 4wd suspension stands up to it better, and in the snow of early March, it was not passable without the SUV (more for the clearance than the 4wd however!) Earlier this year I swapped my IX35 for a Leon diesel, which I love, drive hard and gives 48mpg day in day out. I am wondering whether to consider adding another car to the fleet for SWMBOs daily use, which will be more fuel efficient and save wear and tear on the Kia, but I'm not entirely  sure the sums add up.

• Vauxhall Corsa D 2007 1.3 CDTi - Engine doesn't pick up and runs rough 3 Dec 2014 (Forum)
  The problem slowly got worse so I searched the interweb to see if anybody else had suffered the same problem and it seems that a few people had but nobody came up with the fix to this problem, just loads of none-relevant theories. So I was on my own, first I changed the air filter and then the diesel fuel filter, this made no difference. Further searches on the interweb on rough running engines seemed to point to the Mass Air Flow (MAF) unit being at fault, this unit measures the air flow into the engine and sends the relevant signal the the engine's Engine Control Unit (ECU).

• "Never again" jobs 23 Sep 2006 (Forum)
  The lower cover on the cambelt refused to "snap in" to the upper cover. You wouldn't believe how much time I lost here. The mother of all air-locks was present in the fuel system when re-starting. I have bled the fuel system on this car several times, and this is the one and only time it has decided to soak me and most of the engine bay in diesel when I eased the filter outlet pipe off.
