Discovery TD5 M&S lights flashing

Got the M&S lights flashing but the car is not going into limp mode. I can only select R N & D. Only had the XYZ switch replaced last year so unlikely to be that. Are there any other things it could be?

Could be many things and the only direct way to the issue is to read the fault code stored in the transmission ECU

Thanks Sierra, after a bit of proper searching I found out it could be the red plug on the ecu. So I took this out to clean and found some oil in the bottom end of the plug. I've cleaned it out the best I can with kitchen roll and the issue seems to have stopped. I will get some electrical cleaner and blast the plugs properly to get the oil out.

You have to replace the injector loom ASAP

You'd have thought he'd have found this out during his searching. Maybe he has.
Sounds like the MAF though. Especially if it runs better with it disconnected.
Could it be a combination of the MAF and the dirty ECU plug?

I insisted with the loom cos the man didnt mention it beside the contact cleaner... the MAF has nothing to do with flashing M+S, the oil in the red plug can mix up the CAN signals if it gets untill those pins

Sometimes at the side of the road its a bit difficult to do efficient search with a phone.

the loom was replaced middle of last year so I expect there may be some oil left in the main wiring loom. Can these looms fail as quickly as 12 months (3000 miles ish)

if it was a cheap aftermarket it can be sh*t on arrival.
