Hi Everyone,

I am seeking advice on how to deal with the EGR valve on my 1.4 HDI 16v engine, I inherited the car last year and very shortly after the engine management light (eml)came on, I took the car to my local independent garage who looked at the fault codes and diagnosed the egr vale, cleared the faults and all was well for a couple of weeks and the same thing again, and so on until last week.

I took the car in for it's 40k service and fitting of a blanking plate after reading through some of the threads on here. The eml came on yesterday, I took the car in this evening on my way home and we read the faults, the EGR again!, fault cleared and re-set all ok, travelled 1/2 mile down the road the eml came on again.

The egr was cleaned before the plate was fitted and the car was serviced, I would really apprecaite some advice on what to do next, don't get this problem on my Land Rover Discovery2 with blanked egr.

Also can any one recommend a reasonable fault code reader and re-setter device like the Nanocom.

Regards

Clive

Welcome to the forum CliveXTR

I think for your fuel type and year, the only choice is lexia. Its the only thing that will talk to and fully explore diesel C3s of 2002 to about 2004. (you may be lucky and have full OBD2, but its still not as fully featured as lexia.

You can find out about lexia tool in this topic.

With lexia you can read the fault codes and start looking in the right direction. If the EGR is not faulty, then it could well be a sensor that is used to calculate EGR, like the MAF?, but don't go changing bits until you have the error codes as this can get quite expensive and have no solution.

Hi Clive,

This is my pet topic :)

Change your fuel filter- my car once a year throws up a engine management light, and an EGR fault code. I change the filter, and the light goes out a couple of days later. What seems to trigger it is continous low speed (60-65 mph) motorway driving in my case. I change ther filter, give the engine a bit of a workout, and the car is fine :)

Have seen on another forum that some cars,not Citroen, will have problems if the EGR is blanked off.

I would use the blanking off as a diagnostics aid. You can see quite quickly if blanking off the EGR has made an improvement or not and then you can remove it and carry on fixing.

This way you can make a quick and cheap check on the EGR and discount it or include it.
