EGR RECODING / RECALIBRATION FOLLOWING REPLACEMENT

Hello

I recently had to have my EGR valve replaced by my local non-specialist garage at short notice following EGR failure. Due to timing issues ( going straight off on an 800 mile round trip on the day we got the car back) I did not have time to test the car (garage had road tested for 20 miles) and whist it by and large ran well, there were several times during the trip where we experienced :
* engine dying on startup
* engine dying on engaging reverse gear ( automatic)
* reluctance to restart following the above
* chugging / bogging when asking to accelerate at low speed
* kick down seemed more sensitive than usual

The garage had to fit 2 replacement EGRs in two days as the first leaked coolant. It has since been suggested to me that the replacement EGR valve has somehow lost its coding / calibration.

Can anyone confirm / deny this ? Does anyone know how to do this or what the settings should be ?

I have noticed that there is an EGR related process in the service section of the FL2 Hawkeye data reader but cannot find anything relating to this in the Hawkeye manual ?

Thanks

Dave

If it is like BMW egr valves on B4x/B5x diesel engines then the egr valve needs to be put into instillation position via a service function to avoid damage to the valve also BMW systems need to have adaptions reset.
