1.8 tdci problems

[vtrman]

Having some issues with our 1.8tdci ford c max , when the car gets up to temperature there is a strong vibration through the car at idle , it drives perfectly with plenty of power , no black smoke on acceleration etc , the egr is blanked , clutch and Dmf have been changed in the last few thousand miles , the vibration stays when the clutch pedal is pressed , no vibration at all when engine is cold , any ideas ?

Hard to video it but this is the engine at idle when warm

Weak or broken engine mounting would be my guess

 

[vtrman]

Do you think a worn engine mount would only cause it when the engine is warm? It idles perfect when the engine is cold

 

[Nickyyy]

Would it not idle a bit faster when the engine is cold?

 

[brendy7]

I would say it's an injector sound a bit light on one of the cylinders

 

[vtrman]

Yes probably does idle slightly faster when cold , should have also mentioned , hot idle smooths out with a very light rev

Had a few spare minutes to look around this this evening, I've attached a photo of the drivers side engine mount , safe to say it's shot ! However has anyone ever known a worn engine mount to cause this vibration only once the engine has warmed up ?

Guessing if it's an oil filled mount, maybe the oil warms a bit or becomes thinner as it's been vibrating for a while, so it's becomes more slack when warmer.
That's a guess....It's late and I could be talking sh1te.

Still living with this problem, had 3 mechanics look at it and none of them can find the problem , no codes stored .
The only other thing I've noticed is if the cars been sitting for a few days it may not start first time and when it does start there is a puff of whiteish smoke !
It drives perfect in every other way , plenty of power , no excessive black smoke when accelerating, mpg is fine
any ideas?
