Hello there!
I own a P38 with a 2.5 diesel. It is from June ‘98. Automatic gearbox.
When I bought it last year, the previous owner told me that the occasional dip in rpm that was present, is caused by the fact that it had an upgraded ECU.
As the upgrade results in more torque and the dip in rpm every now and then was not really an issue for me, it was ok.
But since recently the dip is more often (every 2 minutes) and the engine frequently stops completely now. Normal driving is still ok, it has enough power and starts perfectly.
I am under the impression that it has to do with the replaced ECU. I have the original ECU cable system but not the original ECU. I checked the type that is in place now, and this is an ERR 7301.
I want to replace this with the original, and I think that this is an ERR 7300.
My local Land Rover specialist looked it up through my VIN number and is quite sure that this is the one, but not confident... He says the ERR 7113 might also be ok.
Can any one confirm that the ERR 7300 is the right one?
Other tips concerning the issue (dip in rpm) are also welcome...
Best regards,
Bouwe
