Hi there I'm new to the forum which I've just joined to see if I can diagnose a problem which I'm having with my van, it's a 2012 Citroen relay 2.2, I've owned the van for 2 weeks and Ive got a problem with the engine which I'm experiencing only for the first 2 minutes, so I go outside start the van in the Morning, starts perfect everytime but I'm experiencing a knocking noise. Think it's only when I'm moving not sure (when engine is under load), after 2 mins of driving it's fine, turn engine off after the estimated 2 mins, start up again and it's fine, it's like when engine gets to running temp it's fine or when it's lubricated etc, it's driving me mad, just hope it's not the bottom end or anything what requires a new engine, I don't know much about diesels but I do know this noise is not normal, it's not the everyday Diesel engine noise. I've got a vid not sure if I can upload it on here or not, if anyone can help me out I would be very greatfull,Steve
