I could'nt tell you.....although if the engine was warm at the time of the test then I would have thought so.
Mine was a pig to start after I removed a faulty roverron synergy box. It ended up being crap all over the contacts on the fuel pressure switch, I cleaned up both the plug and switch contacts and it's been perfect ever since.

It's possible that you are losing fuel pressure when the engine is warm which can result in longer cranking time and consequently smoke on start up. With warm fuel it takes longer to overcome any leakage into the return line and build up adequate pressure for efficient injection.
There are 2 ways of testing for injector leak back. One method just uses Low fuel pressure and is usually enough to find the reason for a non start. However in your case I would do the test using higher pressure by cranking the engine with the injector electrical connectors removed and see if this produces different results.

Hello all.
Sorry for write back so late, but I was testing the car.
Unfortunately I haven't solved the problem yet. I have been going to different places, I have paid lots of money and I am very fed up with this situation.
I went to a mechanic who suggested to make a little "trick" to have an easier start up. He put a 7 second timer in the glow plugs, so everytime you turn the key to start the engine, the glow plugs are working for 7 seconds (even the engine is warm). So now the engine is starting ok everytime, but part of the problem is still there (you can smell the smoke coming inside the car, there are some strange lights on the board...)
So the timer is a good solution, but the problem is still beneath.

Boby,
How many times have the injectors been out? How many injectors have been replaced?
The reason I'm asking:
I had a similar problem a year or so back. The garage changed all the injectors (I was lucky - still under warranty at the time) but didn't solve the problem straight away as the injector seals were shot. Simple thing - When cold, they sit tight and the engine starts, when warm, the expansion allowed some leakage so caused unburned fuel (white smoke) and difficult starting. Quick check for compression and torque up maybe.
Hope this helps.

Hi all
try the coolant sensor. My td4 was exactly the same at starting when warm. I changed the cam sensor and had injectors checked but still same problem. Cost me a tenner for the sensor and did the job myself which was quite easy to do. Hope this helps and is the cheapest option. Simon
