Just changed my thermostat

[doogie]

Right, new stat in, good bleed and my gauge still doesn't go past quarter way (and I have new brown and blue temp sensors so that shouldn't be an issue)

Incidentally, (possibly related) I have an cabin heating issue....... my fan works fine on all speeds, the temp wheels seem to do nothing, and the top and bottom sliders always give out hot air and the middle slider always gives out cold (I've tried changing both the temp wheel position and it doesn't make any difference) - I regulate cabin heating by moving the sliders around and changing the fan speed rather than using the temperature wheels (no AC)

Does that give any pointers to this problem? Shot/ clogged heater matrix or something ?

Cheers :-)

Huh?

I was replying to bimmerd00d's request for a pic of my PDA setup.

Literally, all you can see is the PDA connector cable poking out of the gear stick cover, so it's not really picture worthy... although I may still do one.

top one all the way to the right is defrost.
middle one is the vents.
bottom is floor vents.

Still kinda sounds like air in the system but you have heat...hmmm.

How big of a hole did you drill in the stat?

[doogie]

Yeah, I only have heat out of the top and bottom, not the middle.... the middle all the way to the right gives cold.

I will try some more bleeding, but I've bled coolant out of the the tstat housing and then out of the radiator bleed.

It was a small hole in the stat.... and as far as I'm aware of, I've *never* had the gauge at 1/2 way since I bought the car six months ago, it has always been at quarter, and this is the second stat.... and this is with the first one not drilled and then drilled. Think I used a 2.5mm drill bit which was the smallest thing I had to hand.
