Hi, I have a 2.0 HDI (90) 53 plate Xsara Picasso Exclusive. This past week I have noticed a strong diesel smell coming into the cabin and it has been traced to a leak to the right side (looking in on top of engine) of the main diesel injector pump, most likely the o-ring has went.

I took it to a local garage and they said they last tried replacing a o-ring on the same kind of engine (Peugeot) and it just made the problem worse, the reckon a new fuel pump will be the best option.

The only factors that put me out here (aside from cost) is the possibility this has been caused by the fuel filter being replaced recently at its major service. There is another post on this board ([url=http://www.honestjohn.co.uk/forum/post/index.htm?t=32784]here[/url]) which specifically advises against the fuel filter being replaced due to contamination getting in and killing the fuel injector pump.

If the fuel filter was replaced incorrectly and something got into the injector, could this have resulted in the leak?

If this is the case I will need to ensure I get a new filter unit as well as replacing the fuel pump, if not I will feel more at ease in replacing the pump knowing it is unlikely to fail again..

I hope someone can help - Or suggest a cheaper option!

Thanks
