MC TDCI Engine Malfunction - P269F

[manchu]

My mrs had engine malfunction warning come up on our late 2012 MC Mondeo today. Forscan shows:

Code: P269F - Exhaust Aftertreatment Glow Plug Circuit Open

Additional Fault System: Actuator Stuck Open.

I cleared the code and took it for a 10min drive. Fault didn't occur again.

I've found this which says to replace fuel vaporiser system. Sounds expensive!.

I bought the car a year ago at 72kkm. It's now got 90kkm and gets decent runs weekly so wasn't expecting DPF system issues.

any tips?

Is this a problem I should get looked at soon, or OK to just wait and see?

I'm pretty sure it's the injector in the exhaust for the dpf. I wouldn't say it's common but I've replaced a couple over the years. Failing to rectify it could possibly lead to a dpf failure. That would be expensive.

Check yellow 20Amp F6 Fuse (location in owners manual if not sure). If blown, you will need to replace the vaporiser as it can short out from overheating.

One possible cause..

Update: I drove the car to work today and dropped down a gear or 2 on the freeway for ~20km to force a DPF regen.

After a few minutes I noticed the regen start on forscan. EGT went up to ~630degC and I watched the DPF soot load steadily decrease from 75% to 25%. It seemed to bottom out at 25% and EGT returned to ~200degC.

Since the regen worked OK today I guess there's the issue with vaporiser/glow plug was a once off. Or at least not something I'll stress about until P269F happens again.

On a side note, the DPF regen process seems a bit flawed. Mid way though the regen I slowed a little and almost as soon as the RPM dropped the regen stopped. I dropped down another gear and it started again. My point is that the regen seems to only work at much higher RPM than the car is likely to be in if driving in Auto. So the process requires driver intervention but the driver has no idea if regen is needed or if it happening (unless monitoring through OBD). That's my simple take on it anyway, but surely there's more going on.

cheers. that's the same TSB as the link in my OP, but with the full repair instruction.

What scantool are you guys using?
I agree that some indication of regen. would be useful. Mine always seems to start as I back her into the garage, making the fume situation ten-fold worse than normal. No doubt it happens more often, but that's when I notice it.

OBD adapters go from $15 to $150, I have the $150 bluetooth which does HSCAN and MSCAN, but plastic mods to the lid of the diagnostic link connector are required if you want it on all the time. The idea is to read the codes on the spot while the engine is still running, sometimes they are erased.

The best software for phones is Forscan. My opinion.

[manchu]

Mine is a $20 fella. ELM327?? wifi rather that Bluetooth because I'm using with an iPhone.

[whitelion65]

So you didn't find their apps useful??
What mods have you done to the OBD port lid? I'm guessing it could be relatively easily removed.

Forscan works for me.

I had to grind off a bit of plastic on the inside of the lid to close it on OBDLink MX adapter. That adapter has auto power off so no problems with car battery.

I have the Bluetooth version. ELM327. Works ok on my Android

That's a neat photo of the vaporizer. What's the software?
Funny how the engine itself is so reliable it's not given much attention compared to the pollution control systems.

I have tried a few
Torque lit and scan master are the only ones that seem to work...

I remember it. I saw it and had a bad experience with my neighbour who wanted to know what we were doing outside so late . . .

Well 7 years and 80kkm later I’ve had this fault come up again.

Car drove fine (no limp mode) with fault active and the fault cleared ok with OBD scanner so once again I won’t be stressing until it resurfaces. Hopefully in another 7yrs ;)
