Lack of power
After hours of scouring the internet for answers...I give in Crying or Very sad

Had an IRB remap and dirty air work removed ages ago Thumbs Up Got up at 2.00am this morning to go to work and struggled to pull up hill. Scangauge shows P1409, P0100, P0404 with the MIL lit. I believe points to EGR? I've also noted that the "chukka chukka" is no more.

If the EGR has been by passed/taken out??? then how can it develop a fault?

Since having the remap it has been faultless and great to drive Very Happy

Is the egr fitted? I presume so if you had the chucka chucka noise on shut down. The get can be disabled during driving but then still carries out the cleaning cycle on shut down. Maybe during the cleaning cycle it's stuck all the way open?! Or is wasn't programmed out in the first place and is now broken.

On a TDCi the EGR will not have been removed, merely turned off in the s/w.

Some remaps turn it off altogether, some leave the cleaning cycle on shutdown still active.

If you used to have the chukka chukka after the remap, then your map is still ordereing the cleaning cycle which is, of course, operating the EGR through its full range of movement. It is quite possible therefore that it has failed, open, during the cleaning cycle, whcih woudl undoubtedly cause the symptoms you describe.

If so, you will need either to remove and clean the EGR in the hope that is starts working again, or replace the EGR. (I suppose that you could possible fit a blanking pate in the exhuast gas passage and leave the EGR alone as well).

In my opinion there is no point in having the cleaning cycle if the EGR is turned off in the map unless you intend to remove the map and reactivate the EGR. If you don't, it is simply asking for this failure mode to occur.

Thanks for the replies. Just back from Landranger garage at Atherton where Martin very kindly gave me five mins and plugged his tester in to confirm as you have Thumbs Up New EGR ordered for Monday.

Might be of some help to others...

Took all of ten mins to whip off the EGR Very Happy (after reading horror stories of two hours..)

There seems to be a blanking plate on my EGR? So I'm assuming that the ECU is asking for a return signal from the EGR (that is fooling the ECU into doing it's job) to keep it happy?
