I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you,

Hello and Welcome..

My name is MIKE - Im happy to help / advise you ...

Your symptoms are that of faulty or plain worn out glow plugs... If these have not been checked or changed, that would be your most likely issue here.

IF its not that - ie, you have already done that -even though its not mentioned above - then you would need to have a plug in diagnostic test done - one to check for any relevant fault codes - and then act on whatever is retrieved - but two - to run live data tests on the fuelling system - to check pressures etc etc... One way or the other, that will find the cause of the problem you have there - such is common with these models...

Do let me know if you need anything else at all -

Kind Rgds - MIKE.
