Thread: TDV6 2.7. Engine not start after fording

Graeme, do you know if the 2.7 has any sort of protection that would cut out the engine if it detects water in the inlet?

I do not know of any such device fitted to any of the 2.7, the 3.0, the 3.6 and the 4.4. .

My initial thought was a dead TCCM as already suggested due to the raft of can-bus faults including loss of contact with the TCCM and that a dead TCCM isolates a whole stack of other modules due to being a can-bus gateway. However IIRC the BCU is part of the engine bay fuse box so could be that module.

The fact that it stopped suddenly and then later started and was noisy worried me, especially after possibly ingesting a small amount of water.

Graeme, nope actually I had a early night, so no excuses there, I don't mind admitting I had a major brain when I wrote what I did. ... Doh! ...

me too!!

Well, removed sill covers etc today. Lots of water in the wire loom area. Dried out. Cannot see any in the inside fuse box area.

One Plug behind the battery low down was wet. Pulled apart and spray out with water Dispellant. Left open to dry.

Will do some more later today. Check some more wires and connectors as suggested on here.

The air filter was damp on one side only. The other was bone dry.

Yes, in very deep.

For what it's worth about six months ago I had the passenger side sill and front foot well full of water for several days from a busted sunroof drain pipe. It took that amount of time to dry it out even with a wet and dry vacuum cleaner and lifted carpets. Maybe I was just lucky but from my experience even though the loom was under water all of that time it didn't cause any issues.

I'm assuming it's a D3, water in the BCU was common on the D3, hence why they moved it to the other side of the engine bay, I'm also assuming there is supposedly more protection from water ingress over there.

Hi Redback,

Which one is the bcu?
