I have tried disconnecting the sensor to no avail, it doesn't seem to make the engine run as smoothly as one with a blanking plate fitted. I think mine may be stuck open so whatever I do with the power to the EGR vlave makes no difference.

What do you mean by reconnecting the monitor pins?

Instead of removing the sensor - remove it from the system by making the ECU think its connected. Now ive not looked at the AT ALL. but some sensors if you connect say pin 2 and 4 then the ECU thinks the system is working.

Your only getting a warning because:
a) the ECU is detecting a real fault (bad)
b) the ECU is detecting a difference in its sensor values - which is a sensor value error.

it could i suppose be an emmissions monitor something along the lines of a petrol lamba sensor registering a high value.

either way you need to find the offending sensor and fix that problem.

I think the warning lamp is a result of extra ambient air passing over the Mass Air Sensor in the airbox, thats what the guys on the transit forum say anyway. So I dont think adjusting the actual EGR sensor will make a difference.

I think the cure is to either try and widen the acceptable range of air read by the MAS in the ECU or use something like scanguage to reset the fault before the lamp comes on.

I dont think fooling the MAS will work though becuase this sensor has to read the actual ambient air flow so the ECU knows how much diesal etc is required. I think the range on the MAS needs to be adjusted so it can accept the higher air flows.

I know it needs a development house such as BELL to find the answer to this one, any news Pete?

Here is a picture of what you are blanking off

Humm , Now im wondering if i made a plate that had ALL the holes that the EGR cooler has got but all small , EG 19x2mm holes in the same place as the originals then you are not blocking some of the holes but are restricting them all slightly.

As soon as i have a car available for some more time ill do some more testing on this and hope to find a cure.

Regards Pete

I have been running with a 12mm hole (biggest dril bit I had) and so far there is no warning light on, I have driven more than 3 driving cycles, the amount that would normally put my light on. I dont think the engine is quite as smooth as a fully blanked EGR but I think that is to be expected.

Hi All,

any news about the EGR blanky plate ?

Does somebody found if it's possible to fully blank the EGR, without having the engine warning light switching on ?

Regards,

Eric.

Just took mine out, never found a way to disable the warning light fully

Took it out cause my def is beeing towed to the dealers so
