Turbocharger wastegate short circuit CURRENT

i read my fault codes today and this appeared up,
Turbocharger wastegate short circuit current 01-05

I get a bit of blue smoke and misfire today, first time ever, I stopped the engine, restarted and it was fine.

The fault seems funny to me as it is not electronically controlled wastegate..

Could this be related to the misfire and blue smoke incident or purely coincidental.

Should I just start with the usual suspects, loom oil etc ?

Thing is it has run perfectly clear since, only lasted about 20 seconds.

Guessing the code could be for the electric vaccum control valve that controls vacuum to the wastegate diaphragm, what it means sorry not a clue !

I thought the diaphragm was just controlled by a pipe from the induction pipe just before the inter cooler ?

AFAIK td5 disco's wastegates are ECU controlled but Defenders are not. Roel

^^^^ +1

Discoveries are ECu controlled, defenders are mechanical, so there's no "error" code that can occur from them.

Is it possible that the error code is generated because of over or under boost pressure in manifold then ?

Maybe the pressure sensor in inlet manifold faulty ?

Can you clear the fault and see if it comes back? That's what I do with my D3. If it comes back quickly I will look further otherwise it's just one off the things.

I think over boost will have it's own faultcode, under boost I don't know. The td5 will go to limp mode if to high manifold pressure is measured. Roel

If it is over boost, it will log as "turbo charger over boost"

From what it seems, there might be a wiring issue.

Clear the faults first and then see if it comes up again. From the land of the most expensive land rover defenders on planet earth. At �125k for a XS 110 csw and you get to own it only for 10yrs! Please find me a good reason to stay on this island.

Cleared the fault 2 days ago and hasn't come back.

Still a bit puzzled how I had the blue smoke then just clear. Hasn't reappeared either.

Beginning to think it's something with the injector loom.

Is there oil in the red connector at the ecu? Roel

Then you probably not have a injector oil loom problem. Roel
