Hi, I wonder whether someone might have an idea why my 2.5 diesel P38 has suddenly decided to become difficult to restart after turning off the engine for 5 or 10 minutes. It has been fine up until yesterday when it was difficult to restart after being parked for 10 minutes.
The engine was at normal temperature after a 20 mile journey but when I tried to restart it the motor just kept cranking until it eventually spluttered into life. I am fairly sure that I pre-heated before I restarted. I did notice, earlier in the day, that occasionally, on tickover, that the engine would seem to miss every now and again which has not happened before. After spluttering to restart the engine ran smoothly as normal.
Also, something that has never happened before was that the engine suddenly cut out as I moved the gearstick into "Drive". I pre-heated again but I had to crank the engine over for maybe 10/15 seconds before it fired and even then it just spluttered into life. But everything ran fine once it started.
Again, I noticed, this morning, that when being started for the first time today the engine did a couple of missed beats while ticking over, but, again, after a quick rev of the engine it seemed to be OK. Any ideas would be appreciated.
