• 1996 Peugeot 106 XND - Leaking Fuel Pump 17 Feb 2014 (Forum)
  The fuel pump on my P Reg 1.5 Diesel Peugeot 106 is leaking fuel- looks like from near where the pulley for the cam belt etc attaches. My car has an immobiliser key pad which  links to the pump. Is it possible to replace the fuel pump and re-program the new pump, or must the replacement fuel pump come with its code?

• Why waste money on Diesels? 21 Mar 2002 (Forum)
  Can anyone explain why a vast ammount of money is spent on developing 'cleaner' diesels, and trying to get them to the same level in refinement as petrols, when this money could be spent on more eco-friendly (hatefull noun I know) such as dual fuel cars, hydrogen fuel cells? As far as I know, Diesels are still very polluting, PM10 particles or somethink, yet these seem to being promoted as the future.

• 2007 VW Sharan TDI - Petrol in diesel..already driven..worried 15 Dec 2013 (Forum)
    The views and experiences of the various experts and non- experts varies hugely. From what I can understand, if I have a diesel with an older type fuel pump then I should be ok. If I have a modern diesel with a common-rail fuel pump then I should prepare myself for a massive repair bill.   I am not sure which type of fuel pump my 2007 Sharan TDI has.
