For some reason I removed the EGR from the head. Here is its back. Both the gaskets in the gasket kit were wrong, so I bought one from Vx. I imagine the machined groove around the gas channel is for cooling purpose, and the two stumps in the centre are the temperature sensors.

machined slot between gas channel / temp sensor pocket is there so that if the gasket fails , coolant leaks out, down the engine and not sucked into inlet (causing hydrolock ) BANG !
yes to the brass stumps being the ECU CTS (coolant tempreture sensor) ,and the other being the dash cluster sender  :y
(hence why sometimes the ecu temp reading via scan live data is different to the temp the dash reports )

nice photos BTW Mr Paget  :y

Second that.  :y

EGR channel is built into the coolant bridge... Neat bit of packaging as it probably helps the engine warm up times :y
Well spotted, Doc, I see what you mean.
