2011 Defender 110 Puma 2.2 USW Stornoway Grey

Puma 2.2 EGR

Need some advice keep getting an EGR fault

I’m supposed to to be going to Germany with it in a couple of hours

I’ve cleared the fault with IID tool

Will it go into Limp mode if it does again lost power at low revs

Has anyone had similar experience

I had mine replaced but needed the MAF sensor replaced also.
Runs like a dream now 👍

If the EGR is sticking and triggers diagnostic trouble codes it will trigger the check engine light and put vehicle in limp mode.

As you have done, clearing the codes will extinguish the Check engine light and take you out of limp mode.

However, if the EGR gets stuck permanently, depending in what position it gets stuck, it can mean you can’t restart the vehicle even once you clear the codes.

More use may free it up, there are cleaners such as Wynn’s diesel egr cleaner https://wynns2021.wpengine.com/wp-content/...ner_EN.pdf but I’m not overly keen on using these types of cleaners on a running engine.
I prefer to remove components and clean on a bench.

Re changing the EGR on a 2.2, technically not difficult but the nuts bolts and studs plus pipe clips are a real challenge to get to. When I did mine on the drive it took about five hours, I think I could do it in 2.5 hours a second time. An Indy should take circa 2 hrs.

A new pierburg (OEM to ford and therefor LR) EGR can be had for circa £120, so given the fitting time I put a new one in.
