Hi all, first time poster! I have a 1.8 TDCI that I have owned for a couple of months with 104K miles on the clock.
For the past ten days or so it has been idling rough, not bad, just like a very slight misfire. If I turn on the aircon and the revs increase slightly the engine runs fine. During the last ten days I have noticed no loss in power, acceleration or mpg, the car appears to be running as normal.
On Monday it went to a local mechanic who checked it over for air leaks etc and checked the injectors. He said they are running at the correct pressure, the car is showing no fault codes, but he feels an injector is starting to break down but at present he is not sure which one?
Yesterday and this morning the car has kicked out blue smoke at cold start-up and ran rough, just for around 20 seconds and then has cleared.
This is now beginning to worry me! I have a can of BG244E diesel fuel system cleaner that I will try today but I don’t hold out much hope.
Does anyone have any idea of ascertaining the exact injector(s) that are causing the problem, if indeed it is injector problems? I have read some similar threads on here but none seem to have a definitive answer?
Thanks for reading! Any replies would be gratefully received.
