The TCU needs to replaced. My service manager said categorically that there is in inerrant fault and they all will need removing and returned for reprogramming at the factory.

I'm hoping it's replaced on my next visit. Can anyone tell me what exactly the TCU controls.

Vendée, when you start your car does the ecall light go bright red for a few seconds then dim.

I've never paid any attention to it before but I checked today and yes it does do that.

Before the TCU update mine was ok, now it's dim the whole time. Page 40 of the manual explains.

Yeah, it's supposed to be dim after the initial momentary flash on power up.

I got the ecall failure warning that's why the TCU was updated, unfortunately not successfully it seems.

I'm not sure what you are on about. You said your E-call light was permanently dim and as you pointed out, the manual states that it should be dim when functioning correctly.

It doesn't glow bright red on start up. But the reason the dealer got involved was the onscreen malfunction warning advising me to seek dealer advice. The warning light was still showing bright then dim red before the TCU software update. Also the Ford Pass app no longer connects to the car since the update.
