Just trying to find out if anyone else has had issues with this part and maybe if there're are any defective ones kicking around anywhere.

Not heard of any.  As likely as a 'connections' issue - check the combo meter plug too (some lines come from there).
Only do it right - no bodging please.   Keeper of the failed stator list.   John.

Mine began playing up last year when the RH indicator repeater went dim. Came back for a few hours, then went dim permanently.
It still flashed as it should, but simply not bright enough though.
When I found they cost £400 a pop, I took mine to a local electronics repair engineer who diagnosed a failing diode circuit in a 6-leg IC chip. For a bank of indicator LEDs, this box is not as simple under the covers as we might think.
He repaired the problem for £60.
I've since heard of a couple of other instances where the pilot box has exhibited problems (from the FB page). One guy had a free replacement under warranty and the other is still living with the problem (no LED activity on his LH indicator repeater if I recall).

I was so hoping that was the case JM...
Fact is, once the box had a direct + and - feed to activate the circuit board (NB the indicator repeaters aren't active until the ignition is on) , a + probe on the indicator repeater line proved the problem was in the box.

Hopefully not a new failure mode on a mkII (having, hopefully, overcome any egcv 'futures').

Have you had the PCB out - all dry in there? (though I suspect physical knocks may be to blame - well, lack of robustness probably).
Really interested if you look any further into this.

Yes, the two indicator lines do go directly there and indeed the earth for the combo meter seems to come from the p/box.

Mine is still OK after 6 years

Yep. PCB out. All dry. Just a bum IC chip. Physically, it was located tucked away beneath a disc capacitor on the back side of the board. Other than that, not a clue as to why it should have failed and absolutely no idea what the circuit diagram for the PCB looks like. Not my area of expertise, I'm afraid.
