2008 Ford Mondeo 2.2TDCi Titanium X 165,000 miles

Starts fine, but running as rough as a badgers when cold. Lumpy idle and very spluttery when I floor it.  OK when it's warmed up, although still idles slightly rough.

No malfunction messages and haven't put the code reader on it yet, but I'm thinking it might be an injector issue? 

Any thoughts? TIA!

The fact it dramatically improves when warmed, always start with the glow plugs - easy to check, and easy, cheap option.

Beyond that, code reader, ideally with live data around air temp and coolant temp.

Hmm yes didn't think about the glow plugs as I fitted a new set about 5 or 6 years/50,000 miles ago and it starts OK.

Glow plugs are not going to help once the engine is running, try using some proper diesel especially in winter like shell v power👍

You mean Costco's finest isn't proper diesel?

You know it’s not, and if it’s easy enough test if there’s water in the system, often the easiest things are overlooked 👍

A rough running TDCi Mondeo ? I hope your wallet is full. Likely causes are injectors, fuel pump, turbo or internal engine faults due to not fixing the previous problems. And if it's a bit slow to start then the flywheel is failing, which can also make them run badly.

Well aren't you a ray of sunshine this evening!

I've got a bottle of Redex somewhere. That'll sort it!

It might help with the flywheel rattle, but I suspect the clutch might not appreciate it

Well it is a Transit engine so what do you expect!!

Sorry, Rae, I'm gonna have to cry BS to that.  That era Mundano is common rail, so glow plugs are arguably more important once started than they are in the starting process, particularly in current UK temps.


But, yes, I am more suspicious of injectors on that car, but the glows are an easy first check, and you could be lucky - it's Christmas after all!
