Thread: D2 TD5 engine shut while driving

Have you checked for oil in the ECU connector?
What is the immobiliser light doing in the center of the dash?

Ye no immobiliser light comes on the dash
And no oil in ecu plug...
Strange stuff

Strange indeed

As you have a nanocom it may be worth checking all the security settings in the BCU.

Do you have all the light on as normal when turning the ignition on?

What faults are current?, crank sensor cleared now?

All the lights light up as normal on the dash, even when cranking it over...
Noisy crank no longer appears... It was extremely dirty when I pulled it out..
I might need to check the condition on the loom wire?
Would the bcu setting cause it shut while driving?

Just because there is no oil at the ecu red plug doesnt mean the injector harness is not faulty. I replaced mine (no oil at ecu) runs better than ever and I have great fuel economy again.
Injector 1 and 5 open circuit. you report, likely faulty harness.

As far as I am aware the only thing that will stop the Td5 when in motion is the crank sensor, all other faults should be logged but not a show stopper, there may be oil present in the injector loom, pull the connector off the head and check there, it would have to be fairly sodden to stop it dead, have you been having any misfiring or other symptoms prior to this?

It is strange that you are no longer getting a fault from the crank sensor, indicating that the circuit is good

It may be worth checking the BCU setting as it is not unheard of for random changes be made for no apparent reason

The fact that it sometime fires and then not has me pointing toward the crank sensor though - did you replace with new, fit the spacer?, it would be a good idea also to check the wiring loom and connector on the circuit.

I brought a genuine one, what's the spacer? What should the bcu setting be? No misfires, might have been driving a bit quick...burning extra fuel

When replacing the injector harnes, is it replacing any injectors?
