I've disconnected my EGR and car is now running 100% better than ever.

but the engine management light is now on - so I wont know if a real problem arises.

Does anyone nearby have the ability to tell the electronic gubbins to ignore the egr valve?

Preferably without charging too much?

Have you not tried cleaning it out? There is a chance it may fail the mot if it is mapped out as the hydrocarbons will be higher.

Originally I had problems, egr was cleaned out, ran fine for 100miles, then - suddenly - black smoke. So I disconnected the egr ..

Mine went thru an MOT fine when my egr valve packed up. Cleared the fault codes before I went in so I didn't fail on the CEL.

Shark performance who did my remap/dpf delete want £100 to remap out my egr. :(

Removing the EGR tends to reduce rather than increase the MOT smoke emissions in my experience.

I've removed the EGR from a few PSA diesels in the past and they all smoked less and passed the MOT smoke test with slightly lower readings as a result. All EGR is supposed to do is reduce NOx emissions, which isn't tested on a UK diesel MOT.

Tried it again and its running fine. An occasional hiccup especially when driving with a very light throttle and accelerating slowly around 1500rpm, but nowt to worry about. Garage guy reckons a lump of carbon had been lodged.

JD Tuning in South Shields can map out your EGR and do a remap for only £175. DPF removal service is also available

Would also recommend Big Fish Tuning in Stokesley, fair distance from Blaydon but John, the guy who runs it, really knows his stuff.
