Hi all,

been experiencing some issues with my 2012 2.2.Tdci TXS estate.had engine malfunction come on a few times in the past weeks. I have plugged it into my forscan software, and determined it was unable to complete a DPF regeneration due to a P244C fault code.

So reading other threads available, & making other checks etc, I have ordered a replacement valve assembly from Ebay (£180) as opposed to dealer at £250+vat?!, this arrives next week...

 

However around 1 month ago during a routine scan to review dpf soot load etc, It did throw up another code, for the egr...this was error P1412 (EGr frozen).

I had cleared the code, and hasn't come back since.

So this now also has me thinking that the dpf could be trying to regen more often due to a sticky egr valve?

Can easy checks be made for the EGR on this engine, either manually, or using forscan etc.

I'm changing the valve assembly, and am I likely looking at the route cause being the egr?

 

I have noticed that over the last month the regens seem to be more often..

 

thoughts and help appreciated.

this is a link to the part I ordered...I thought cost was good when in-comparison to dealers, although tempted by some second hand units I figured they could be in as worse condition as mine, so opted to cough up..

Hi Simon, recently had the same with my 2011 2.2, i use it as a cab 165,000mls started having many regens two or three an evening, eventually got p1412 up. in a nutshell the EGR was screwed very slightly open still allowing gas through, the effect of this was to increase regens but after fitting new EGR the regens became a lot less frequent but the new problem was lumpy idle on start up when warm. I was just about to go and get a set of injectors when a mate of mine rightly pointed out it was probably a sticky turbo vane, anyway i purchased a bottle of archoil fuel system cleaner, poured that in and then went at the induction pipe with a couple of cans of Wynns EGR cleaner which iam reliably informed also loosens cruddy turbos. 600mls later it still runs like a steam train no more codes :first:

yeah I was thinking my egr is sometimes sticking following the frozen alarm i had. but in the last weeks it hasn't reappeared.

 haven't changed out my injector valve assembly in the front end of the dpf yet, but I have been monitoring the egr and cat temperatures using an app on my mobile..via the obd.

I downloaded the full version of Torque...once I configured my dash you can see all sort.  a clever device to review whats happening live.

I noted that the egr closes during a regen, and once completed opens up again. so far its performing.

I might get some of the wynns egr cleaner you mentioned. But i still plan to change the valve assy now i have it...
