Not sure if it is any help, but I replaced mine - Couple of pics on my thread, sure I have some more somewhere. I'll have a dig.

Also with my broken ext: temp sensor, I was not receiving any hot air at all until 'hot' was actually selected.

I think I may have an internal sensor as well as a spare atc unit if you want to borrow them to try/test.

Pete, I'm not sure how accurate you are. When I unplug my internal sensor, I get an E0 error, when I plug it back in, the error clears.

I have this table which would suggest E4 and E0 is a front temp sensor failure as they both relate to this.

This would also make sense if the wires were cut as they may be touching the car, earthing the cable and creating the E9 error

I got the info off a post on .org, but yours makes more sense as both codes relate to the external sensor.

Not often I'm right about something lol, it's only because I've had my centre console out a hundred times!

How many times ???:laugh:

Well are we counting times removed or days without one in the car?!?!

Thanks Mark - I'll have a play around at the weekend and give you a buzz if thats ok?

Thanks Pompski! Thats brilliant. It is going to be the weekend before I get chance to have a mess around. I shall give an update then...
