Engine management light

Funkykipper · Apr 12, 2015

Has anyone done a check list for when/if the engine management light illuminates on the TD5 or the ECU goes into limp mode.

I had this happen yesterday on a laning trip in the middle of Wales.

Luckily I had a spare new air filter which cured the issue but it was hard work getting off the greenlane in limp mode.

according to the built in diagnostic protocol the Td5 MIL(malfunction indicator lamp) should come on ONLY for two component's malfunction/failure: the crankshaft position sensor aand the throttle position sensor so IMO the air filter thing was coincidental, water ingress to the crank sensor can cause that, also quite common but mostly on autos is TP sensor failure... make somehow to read the stored fault code then you'll know

Brilliant, thanks for that.

It could have been a wet crank sensor.

Another vote for the crank position sensor. I had this happen to me a couple of times and the Nanocom was telling me 'high speed crank error'. A new crank position sensor seems to have cured all that nonsense.

Where is it and is it a bum ache to change?

Its on top of the bell housing. Be careful when unplugging the connector as they can be brittle and make sure you dont lose any of the shims or you'll risk chewing the new sensor against the flywheel when you turn it over. Other than that its a ten minute job if you take your time.

I've just acquired a brand new spare just in case I get caught out again.
