1.8tdci takes 'ages' to warm up

[wild_one]

Compared to my last 'petrol' focus, my current diesel does take a lot longer to get up to temp. When it eventually does get to temp no issues. I was concerned that the thermostat had failed open, but the last time I had that issue (on a different car) the temp would drop away on the motorway and heater output was always poor unless you were in stop start traffic. But, I still think it could be an issue?

I doubt it.  These diesel engines take an eternity to get up to temp especially at this time of year.  I notice you're from London, so if it's stop start traffic all the time it will take even longer than the usual longer time! 🙂

Yeah, I must admit I have heard other diesel owners complaining about warm up times. The issue is lack of heater output more than anything. It gets cold in London too you know

Mine is very slow to warm up too. I have a 2L tdci. Once i go up a few hills it does tend to speed things up though.

I had 1.6tdci fiesta, now have 1.5tdci fiesta. they take ages to warm up, glad I have a quickclear front screen so whilst I shiver I can at least have a clear screen.

You can console yourself knowing that this is a sign of an efficient engine that is using the energy from the fuel to propel the car along and not wasting fuel on creating excess heat (which a petrol engine does more)
