• Volvo V50 Diesel - Wise buy? Volvo V50 1.6 Diesel (better than 2.0l?) 16 Aug 2012 (Forum)
  I'm not so sure about the reliability though. A few horror stories around the internet, which seem to centre on the 2.0litre diesel(poor fuel economy, engine probs) I wonder if the 1.6 diesel unit is a better, more reliable unit. It should also have better fuel economy. Monthly running costs are very important to me, I can't afford a car which is going to let me down.

• Nissan X-Trail (2001 - 2007) - (01-07) 2.2TD - Engine not revving above 2,000rpm 1 Oct 2011 (Forum)
  To rectify this the ignition needs switching off and on again and the fault goes away. I have had the car into the dealer who changed the fuel filter with no curing of the problem, they said that it could be the fuel pump which would be 2 grand to change (the car is no longer under warranty). Any ideas? {The 3 separate requests to include year & engine details in the subject header must have been playing hide & seek when you composed your question.
