44 Engine management system
My beloved 2.0si XM has gone wrong!
The engine management failure light is permanently on.
It came on three times during my journey home last night, but each time went out after a second or so,
but this morning oh dear :-(((((
The engine sounds a little rough, could it be the ’distributor’? Has anyone got any ideas?
I almost expected the alpha-numeric display to show £££££££££
====
Try to disconnect the battery for 10 minutes.
This will reset the injection computer.
If you’re lucky the problem might be gone.
====
Try phoning the service manager and asking for a quotation for a computer diagnostic test only.
This may cost you no more than about £25 and should point yopu in the right direction.
If you have a catalytic equiped car then correcting and managment faults is urgent to avoid catalytic
poisoning.
====
The French Car Co. have now fixed my XM. Hooray!
The diagnostic computer could find no fault with the ECU - the ECU kept saying it was ok!
’Traditional’ searching found a bad contact on the ignition coil.
A bit annoying really as I could have found that type of fault... but it is cold outside!
