The sensor is mounted on the left of the car ( or the right if standing in front looking at it) and is clipped to the windscreen wiper mechanism (at the root of the bonnet). Do a search there are pictures of the thing on the froum.

back at garage today if the electric water pump was dead would that stop the aux heater working

[bofus]

The heater would fire up but quickly reach overtemp condition and shut down. Not sure whether it would auto reset or need diagnostics to reset the fault condition if it had repeated x times.

My aux heater was working fine when I first bought the galaxy. Y 1.9tdi 115 auto. purchased around 3 months ago.

Hadn't realy noticed it had stopped working untill this cold spell.

Replaced the glow plug today and it still does NOT work.

I put a meter on the old and new plug and it looks like the old plug is duff.

I took the complete pump off last weekend as I was fitting a new thermostat as well and the collant was out of the car.

As it has been off the car, is it possible the diesel hasn't bleed through to the pump yet.

SNAP

 

I fitted a new glow plug and nothing.

As a last effort after try bridging the temp sensor, even though it didn't get above 8 degrees today, and checking the terminals to the aux heater pump, I finally thought I would try letting it hang down and surprise surprise, it worked.

I then removed the electrical block from it's mounting and moved the block in different directions and it seemed to make it go on and off. A quick run around the street and the Galaxy was up to 80 in a flash.

I went back to the Galaxy about a hour later and it has stopped working. I will investigate more on Friday or the weekend.

It looks like the wires from the heater are solid core copper and being so tight from the heater to the terminal block mounting bracket it is possible I could have a break in one of the wires.

Having changed the heater plug would mean more handling of the wires and worsening of a possibly broken wire.

I hope this isn't something more involved such as the fan in the heater not turning from cold unless it is off axis.

 

I will update this a I am not the only person in this position or the last.

anyone else with this problem,

first of all, try hitting the heater with a rubber mallet rather than dismantling and hanging it down to start with and save time.

ours stop working after the summer , they seem to like an odd switch on in the summer months as well. so bridge th eterminal and let it fire up a few days.

 

a tap with the mallet and off it goes again. quick and easy.
