Quote from: 847563 on January 05, 2012, 11:52:45I believe the smoke on start up is perfectly normal and in fact, indicates a well lubricated engine. If you've ever seen a piston aircraft engine of the 40's on start up, it's pretty full on. You could be forgiven for thinking that the engine is clapped, but what is actually happening is the residual oil from the valve stems and some upper cylinder oil simply burning off. This oil collects after shutdown and I am quite happy for it to be there. Diesel fuel is an oil after all. Naturally, if it continued after start up or was excessive, then I'd be concerned.My car does not smoke on every first start if used frequenly, however if left over long weekend or longer on the first start it can blow blue smoke for more that a few seconds, I have seen great clounds of smoke on one occasion after left it for few days. If dealer looks as the car it will not smoke as they are unlikely to leave the car unstarted for more than one day. I checked the Glow Plug fuse but cant get it out to check if okay, have never seen glow plug warning light. Possible causes are oil leaking past the inlet valve stems, injectors leaking when the engine is left for a time, blow fuse for glow plugs. The engine does not use oil, so I suspect it not related to pistons and rings. How do check the 80 amp fuse?How does it come out?

Update, since all glow plugs where changed, the car has remained smoke free.
No modern common rail diesel should smoke at startup.
I had mine serviced last weekend and they used a new oil in it. One that glows under UV light to detect leaks (if leaks were ever to occur). Since i had it serviced i have not seen smoke at all. It still smells a little on start up as most cars tend too but nothing untoward!
