I'd you look at oem circuit you'll see many sensors share same ground, I'm sure IAT doesn't.

On my data log above all sensor are effected, you can see the voltage spikes.

Update:

Okay, last w/e I totally removed the EGR valve and air pump, disconnecting all air pump current sensors etc. The Series 2 wouldn't idle at all so something had changed (which I was hoping was a good sign) as it idled before even with the dodgy sensor readouts.

Today - Romain logged on remotely and tweaked the idle and has confirmed that the sensors are all reading normally now, so it must have been potentially the air pump current sensor somehow feeding back into the EMS and throwing off the sensors.

So glad to get it sorted and now booked into finally get it mapped properly in May just in time for the summer.
