My 2010 318D showed reduced power engine fault sign which was traced to be due to faulty EGR valve.This was replaced by the mechanic but there is a engine sign coming on moment I start the car-possibly indicating a sensor or cable fault,and it stays on.
Engine performs and sounds better since changing the EGR valve.Mechanic is not able to explain the sign.
Any ideas what could be wrong?
Many thanks

Take it back and get him to look at it again

I’ve seen many a egr changed due to other problems over many years

Just cause there’s a fault code that says egr doesn’t mean the egr is faulty


If they can trace the problem we can

as said above,,,if not traced correctly you could be chasing the fault spending loads,,check vac lines to egr etc etc

I have now been told that the constant engine light on on starting car without any effect on performance or fuel consumption is due to one of the pins within the the socket next to EGR valve has been damaged.
Is there any way I can change just that bit of the EGR valve? and is this something we can do DIY?

yes
one of the mobile mechanics changed EGR valve recently and since then this has happened.
Car went into limp mode and I was in a different town and was forced to use the mechanic to get home beforr christmas.
Now he wont take my phone calls!!

I get that he might have cocked it up.
But he is over 200 miles away.
But coming back to the question-can that part of EGR valve be changed-it looks like clip on cover with a socket.Local mechanics run the scan and declares EGR fault and wants me to change the EGR valve again.But the fact that engine light comes on the moment I put ignition on points to a sensor or cable fault that actual EGR valve to me

Is this the car where one of the pins on the new egr is broken off or pushed in ?

The fault is different than before the valve change, the new valve is physically damaged, the diagnostic says faulty egr valve, ???????? I guess you need to change the egr valve irrespective of who damaged it

Well most of the messages posted here says EGR Valve fault on scan does not necesarily mean faulty EGR.Fact that engine light comes on even before running the car(and with no effect on performance or power of car) to me looks like more of cable or sensor fault.
