I have read the brilliantly detailed post on changing the pipe that goes to the cooler, but, my v8 diesel appears to be leaking in a different location.
My leak drops down onto the GBox sump (and the large connector plug on it) and streams back along the sump and then drips everywhere.
When you lay under the car, with the 2 gearbox plastic covers removed, it’s obvious it’s above the connector plug but very difficult to identify the location of leak - even with the engine running.
With the near side wheel removed, looking through the gator cover, I can see a pipe that looks damp (though not dripping). It transpires the part no of this is 4e2422891s - I just wondered if anyone has replaced this pipe? (I’ve not removed it yet but looked at the ETKA drawing).

I haven’t taken the offside wheel off yet to see the other end of the pipe (if it’s visible), but, if anyone has done the job did you just pull the pipe through any side?
On the side I can see (N/S) it’s a union connection, so, I guess the offside is going to be the banjo connection.
Any help anyone can suggest would be greatly appreciated.
I have been topping up the fluid and it’s had a leak stop treatment too…..
