James, when I mentioned pinching it during the gearbox swap, I did so because it could have been at any point during removal/refitting and not just as you bolted the two together. For example against a heat shield or body and the like ;)

Point being that the cause of any damage may have unnoticed and/or unapparent.

I now have a replacement loom and hopefully it won't be long before James can get here to fit it.

The car is running rough, particularly at the lights with my foot on the brake. I'm wondering if, to add to my woes, whether I have vacuum leak somewhere.

My latest read-out is as follows:

P0155-04 - O2 Sensor Heater Circuit Open (Bank 2 Sensor 1). Status:Intermittent
P0155-08 - O2 sensor heater circuit malfunction (Bank 2 Sensor 1). Status:Intermittent
P0300-08 - Unknown Error. Status:Intermittent
P0302-08 - Unknown Error. Status:Intermittent
P0304-08 - Unknown Error. Status:Intermittent
P0306-08 - Unknown Error. Status:Intermittent
P0150-01 - O2 Sensor Circuit High Voltage (Bank 2 Sensor 1). Status:NotDetected
P0150-08 - O2 sensor circuit malfunction (Bank 2 Sensor 1). Status:NotDetected
P0150-04 - O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 1). Status:Intermittent

Bank 2 misfires to add to the list...

Usual suspects...

Oil/water
Coil pack plug not plugged in or plug not fully seated.

That's the end of the road!  >:( >:(

James is here today and has replaced the loom. Guess what? Bank 2 Sensor 1 Heater Circuit malfunction AGAIN!!

It's NOT the sensor.
It's NOT the loom.
It's NOT the ECU.

Feel like driving the damn thing to the nearest scrappy.  >:(

But it’s not :-(

We fitted a replacement loom today

Tried swapping b1 and b2 sensors and the fault doesn’t move

Then we fitted the a different ECU

Despite this - the second the car is started - it logs “open circuit” fault code for the lambda heater on B2 S1

I hate to say it but I’m short of ideas ….

SORTED!

Despite what the ECU was reporting, it turns out it was not Bank 2 Sensor 1, but Bank 2 Sensor2::) ::)

There is clearly some connection between the two.
