Mondeo ST TDCI Glow Plug Flashing
Discussion
Hi All,
My car (2005, Euro 4 ST tdci) has the dreaded flashing glowplug light occuring much more regularly than before. Turning on and off momentarily clears it, but it will return as soon as I am driving hard in 3rd, 4th 5th and 6th gears. The car is otherwise smooth and there is hardly any smoke from the exhaust.
I am wondering whether my EGR which was replaced in July 2013 and has covered 20k miles since might need changing.
Is this one on ebay a good EGR to buy? It looks like a pattern part, and am wondering if it has to be genuine jaguar/ford?

PS: if I remove the plug for the EGR, will that help determine if it is the EGR, and are their any negative consequences of running car with plug removed (i.e poor MPG, turbo wear)?

Jim the best Ebay purchase for Tdci EGR is a blanking plate - don't waste time or money replacing valve.
On a Euro 4 or 5 the engine management light will stay on as a result of blanking but doesn't affect performance or economy.
Regarding flashing light my advice based on experience would be replace fuel filter, then if problem is still there then next step is normally cam sensor (around £15-20 on Ebay). Known weak point on these engines - try a quick google as they were modified. Bad originals were black, replacements grey.Sit in front of head just below fuel rail. One 8mm bolt and a multiplug means change in 5 minutes.

Thanks Dave. I will try your suggestions in the order you have mentioned.On a Euro 4 or 5 the engine management light will stay on as a result of blanking but doesn't affect performance or economy.

Is the EGR blanking plate fitted in one place or are their two locations that are blanked off? Also, should I get a genuine fuel filter or will Wix fuel filters be ok?
Edit: Dave is this the correct sensor:

That looks like the correct sensor.
Just one blanking plate needed - there is a long metal tube held by 2 nuts to side of egr valve.
If you look at some of the plates on Ebay they have locating lugs so you do not have to remove the egr pipe.
Just loosen nuts a few turns, slide the plate into place and tighten back up.

Thanks Dave. Plate arrived today so will blank if off over Xmas.Just one blanking plate needed - there is a long metal tube held by 2 nuts to side of egr valve.

Since I posted my first message, I have developed a metallic rattle noise when I partially press the clutch down/bring up to biting point. The clutch engages fine, no slipping and the car pulls strongly. Is this the first signs of DMF failure or could it be the clutch release bearing?
How long can I drive before either of those factors leads to a catastrophic failure?

You need to read the fault code before you start jumping to conclusions with the EGR. It could be fuel pressure related. BTW, only use a OEM or Delphi fuel filter.
Thanks for the input. But is it a good idea to blank the EGR anyway? I suspect mine is ok and was cleaned in July 2013. My car does not smoke at all even when booting it.Sounds like DMF is starting to rattle as you suspected.
They can cost a fair bit to put right, however if you can live with the noise they can last a while.
I had 2 tdci 2.0 mondeos as private hire cars and covered a lot of miles in the them.
DMF started rattling on my 1st car, and lasted about 20,000 miles before I replaced. Would have lasted a bit longer but once customers start querying the noise it was time to replace.
Parts were around £350 inc. brand new clutch, and labour around £200.
Re. EGR blanking - always a good idea to blank off. Amazing the amount of crud that accumulates. I used to remove the inlet manifold to clean out as well, as the ports can become almost fully clogged up.

Thanks Dave. Ok EGR will definitely get blanked today. 20,000 miles is pretty decent for a failing DMF so i think I will carry on driving until it fully goes.They can cost a fair bit to put right, however if you can live with the noise they can last a while.

Interestingly, my dad had a 2.0 TDCI 130 as a private hire and had no end of troubles with it. The DMF was changed twice, injectors were replaced and it had other issues too which warranted an install of a reconditioned engine. Admittedly, my dad was not mechanically sympathetic to the car - but it does seem he had a bad car to start with.
Conversely, my car has been pretty well-behaved for the last 20k miles (most of which were motorway), but my job now means I do shorter journies. Thankfully, me being me, I go the long way round to work so the car is fully up to operating temperature.
A friend has an ST TDCI and it is coming on to 260k and still on original clutch, but he does only motorway driving - which is the natural territory for Mondeo diesels of this era.
