About 6 months ago I purchased a 2010 Mondeo titanium 2.0 diesel estate. The mileage is now just over 100K
Absoukty love the car but recently I've noticed a couple of things that I'm concerned about.
Firstly the car starts fine from cold, no error lights and seems to drive well.
When warm and generally when on a run 50-70mph I occasionally find what i can only describe as fumes in the cabin. This smell comes and goes on long journeys. I also notice grey smoke coming out of the exhaust this cones and goes . Please note I dont always notice both of these symptoms at the same time.
When I notice the grey smoke if i open the car right up the smoke gets worse for 10 or so seconds and then disappears. If I dont open the car up it continues to smoke. Once the smoke has gone I still notice the smell from time to time.
I have also found when i see the above symptoms the idle seems very off. Probably miss firing at idle. Again this goes away
All of the above isn't seen when driving around town or when cold. Only when the car is on a run these symptoms occur.
I have been reading loads about grey smoke etc and a lot points to leaky injector. What do you guys think.
Any advice will be appreciated.
Thanks in advance
