Time To Check Your Boosters Boys And Girls

[Brookydave]

Sorry to be really dim, but how do you turn it on - I have a tdi 90bhp and a AC dial I push to get cold air (works!) and another dial next to it with a loopy symbol that lilluminates when depressed - I dont understand, and a button with with like heat under the car. All too complicated!

Cheers

ok, you have three control knobs for the heating and vent system and a circular button to the left of these at the top of the center console, the first knob controls the fan speed and if you push it into the dash it switches the vent system over to recirc, yellow indicator luminates and no fresh air :huh: the second knob controls the air temp and the AC again a push to operate switch, the third knob is to control the air flow direction, you with us so far? now the circular button that is to the left of these with the picture of the car on it above the heated screen buttons is the on/off switch for the rear heater unit! the air speed and temperature selecter for this heater is on the head lineing above the passenger side 'C' post, this is a recirc only unit! and is not linked into the AC system it just recircs the air and heats it, it cannot cool it :(

as for turning on the Aux/booster heater, the external one under the car! you either need the four button clock/timer to do this or you can short out the temp sensor and fool it into working! there are several posts on how do this and even more on how to fix the unit if yours doesnt work? that is if you actually have one?

[sanjsanj]

Can someone post some pictures showing the procedure of checking if the aux heater is funtioning properly? I've been meaning to do this check for a long time but can't seem to find the temp sensor under the bonnet. There is a gap but its tiny! Unless the old owner did his own work under the bonnet! :huh:

[Guest gooner52]

so can it be tested on the mk2,sorry if this has been answered,

 

or do i need to wait for a cold morning and get up early to test

 

thanks people :huh:

[marinabrid]

as far as i know all tdi have the sensor clipped to the n/s wiper link arm or very near, its up it the top part of the area where the link arms are on the wipers, easier to see if you remove the big panal that diverst the water away, its round with a small 2 wire plug on it and is clipped ito a holder on the link arm, to test the heater at warmer temps unplugg the sensor and pop in a bridge usually a micro fuse with the legs bent in a touch, then the heater will get a permanent signal to start .

[Brookydave]

Thanks 3.5bullet for the explanation.

I have no worries about my booster heater :huh: Thats because mine hasn't got one .

The easiest way to test if its working is wait til the temp gets below 10c, start the car, after a couple of minutes turn the car off and you'll here the sound of a jet engine coming from below the nearside rear door!

If the thing isn't firing up you will get plumes of white smoke from the same area, if it doesn't work at all. don't worry it just takes about 10 minutes longer for your car to hit operating temp!

surely the easiest (and cheapest!) way is to start the car and get off your backside and look for smoke?

My point exactly Sanj...but also...don't fret about it...we all stress about the aircon in summer and the aux heater in winter!! Save the strees for the aircon!!! Have a stress free winter!!

Mine came on the other day. Ambient was 12 C, but of course the sensor for the booster is in a different place.

 

Interesting that on the colder day on the 3 mile drive to work the temp gauge had actually started to move when I got there, but when the ambient is a little higher the booster does not come on and the temp gauge don't budge!! But of course that when the climate kicks in

Complete and utter cr@p, if the unit doesn't work you've not a chance of keeping warm inside if it's cold outside. My heater packed up last year, I did a trip on the motorway with -3 outside, freezing inside even with coats on. If you turned the heater off with the car stionary and revved the engine in the services managed to get to 90 deg, off on the motorway, heater on after 3 miles back in the cold section and no heat, complete bloody nightmare.

 

Get it fixed you WILL need it when it's cold.

I disconnected the fuel pump wire to mine when it packed up last winter. I just started the car 10~15 minutes earlier, then I only had to drive for 10 minutes for it to get reasonably warm, though never hot.

If it's cold outside theres no way it's going to get warm unless you're caning it to death.

My Aux heater failed earlier this year so I must get round to finding the fault before the weather starts to bite. Is the mini fuse you mention in the bank of fuses above the drivers footwell? I suspect an electrical supply fault as there is no life at all from the heater motor. I have had white smoke in the past when it was working as if the glow plug failed to ignite the fuel vapour so I don't suspect the glow plug giving my problem. Is it possible the temp sensor for the aux heater, that is supposed to be located near the wiper mechanism could be in another position as I can't see it in the area it's supposed to be? The car is a 2001 1.9 tdi. Maybe it would be an idea to run a new cable to the heater unit to test it? Any advice appreciated. KF.

IIRC after 3 faults depending what they were eg Flameout which this sounds like, the ecu decides not to try anymore until codes are reset I suspect you need one of the uprated glowplugs and the fault codes resetting

[johnb80]

Thats about right, when mine failed it had 5 attempts and then wouldn't try again until it had a visit to a main stealer. Pretty sure VAG-COM can reset it so it may be possible that someone on here could lend assistance.
