Aux Heater ?

[gixersteve]

any one know where one could buy a aux heater unit for a 05 19tdi fault code is 66535 and wont clear.

[nandj]

I think, on visual exam my aux heater has had water ingress and is completely US. Doesnt start and has impacted on the heating ability of the car, naturally.

 

My Q is:

 

Bearing in mind this unit is on the coolant circuit, would the fact it is US deem it a "blockage " in the cooling system? Im getting overflow from the header tank on long journeys at high speed and my oil temp raises above the normal 90 deg mark.

 

does the aux heater sit in "series", so to speak in the coolant system (in which case it could prevent flow thru) or does it sit in "parallel", therefore it not working wont prevent coolant flow?

 

Thanks

[big_kev]

Has anyone experience of this model burner?

 

Will the entire coolant system drain if I disconnect the water pipe?

 

Its the latest version ( F-series ) ....either D5Z-F or D5W-F ( can't remember the difference, however its the F at the end that matters ).

 

This was fitted to all Shalaxy's around 2005 onwards.

 

The Glow Plug has a fixed lead and a different design of combustion chamber is used.

 

Bad news is that these units have a history of the Control Units packing up.

 

 

 

 

And yes if you disconnect it all your coolant will flow out unless you clamp or plug the hoses.

 

It should sit be inserted into the coolant circuit between the engine and the radiator.

The coolant should circulate through the unit whether it is working or not.

Says File is corrupt when I try to download it?!

 

Is the control unit IN the housing or situated somewhere else in the car?

Anyway for over €100 I think the best option would be just to go out and start the car a bit earlier in the morning! :46: I absolutely hate not having something working in the car though- it will bug me until I replace it or the car!

 

Oh sorry someone else answered the question re the control unit in another post- thanks.

Trawled through but couldnt find what I wanted so here goes,heater is working fine but would like it running to warm up a switch would be fine or a timer,will a switch sending a permanent live to the sensor on the wiper linkage run the heater.I dont want to leave the keys in to warm the car up.Many thanks

Hi - Long time since I have posted. Have spent several hours reading through Aux Heater posts plus others on fumes in car etc. My problem is fumes inside car - no visible signs of smoke though. The aux heater appears to work OK, slight puff of smoke on start but otherwise seems to come on/off all as expected. Having no desire to drop the heater just for the hell of it, does anyone think this is an aux heater problem or is it more likely to be smell resulting from faulty injector or similar?

 

Glad to see the forum is still excellent as it always has been.

kev,somewhere iir on this thread is mentioned that a pipe is situated near the front passenger pillar,im sure thats where mine was coming in from,soz cannot remember what needed doing?

Hi Kev I assume your getting the fumes coming in when your driving along if you can smell engine/exhaust fumes coming through heater vents I wouldnt think its fumes from your booster heater as that would be taken away behind the car when driving along.

What can happen though is the scuttle plate under the wiper motor area may not be fitted correctly do you know if its been removed recently this has to be removed to get to things like the wiper linkage, pollen filter, electric coolant circulating pump, top suspension strut nut, to name a few

Its held on by 3 bolts but the bottom edge fits under guides which keep it tight against a rubber seal keeping any fumes away from air intake into car, its worth having a look at specially if its been taken off recently

[kevinp]

Gregers - yes, I recall something about air feed and/or pipe on nearside pillar so i will investigate that area.

chrispb123456 - I agree about fumes going backwards out under the car. With the car stationary, I can't detect any fumes coming in through the air vents (it's difficult to sniff around yourself when you're driving!)

Thanks for comments, I'll investigate further. Problem is the wife now has the Galaxy now that I've got a company Focus so I don't get to drive it enough during the week. Will report back when I've investigated further. Cheers.

hi all, just had an issue with this auxillary heater on my uncles 03 plate alhambra, went into seat etc etc and was told it was this and that its either the glowplug or a complete unit as some of them are sealed???

I stripped it off the car this morning and must admit it looks like a sealed unit, these are bloody expensive lol, so just wondering if anyone can 100% clarify that the plug cant be changed before i tell him to go spend a few hundred quid odd on a new one

 

Thanks

Hi If its a D5WZ it definately comes apart, small torx headed bolts to remove back cover. Never heard of them being sealed units.

You may find this link usefull for parts

Hi guys..

 

I *think* I've checked through the thread and can't see this.. but apols if my eyes glazed over too early :(

 

Is there an easy way to just disable the aux heater?

 

Ours locked up a couple of years ago when it was suffering the white smoke issue. We were quite relieved it had stopped, and being used to sheddy cars with crap heating it hasn't been a problem.

 

But it's had the lock reset during some recent work, and rather than spending

Hi there Firstly welcome Tim to the site. Fuse 12 will stop the heater functioning, would be much better to change the glow plug and clean out the soot from combustion chamber. Implications are engine constantly running cold will increase engine wear and to supplement rapid warm up in winter essential for keeping windows clear!! :(

 

Hey thanks :)

 

Point taken about engine wear and other downsides.. although having had it not working for 3 years I'm fearing we've probably done the worst of it now! I guess, it being a nine year old car, I'm looking for fast and dirty - and cheap - fixes now..and I don't feel I have the skills or tools to do the plug/clean myself (despite the lovely photos).

 

I tried (I thought) fuse 12 on the basis of the advice higher up.. but the car stalled down the road and wouldn't restart until I plugged it back in (so I'm guessing it was linked!). I assumed that maybe the fuses were numbered differently in an Alhambra?

 

Thanks!

Hello,

New to this site and just trawled through the thirty pages. I have a "05" plate TDI.

 

My booster heater stopped working a while back. When the car went in for it's MoT I asked the dealer to have a look. They reported that the computer had received three error codes so shut the system down. They had reset it and suggested I just tried it. There was no charge for the work so I can't complain.

 

A couple of weeks ago just after I parked the car two people pointed out my car appeared to be alight. White smoke was coming from the booster heater area so I just assumed it was steam. The car didn't burst into flames!

 

Now it's packed up again so I suspect the computer has reached the error code trigger threshold.

 

Questions.

Can I reset the computer or must it be done by people with the right equipment?

Would I be right in thinking from this thread it may simply be a glow plug issue?

How many different error codes are there?

 

Thanks in advance.

Graham.

There are a few error codes, not sure of the numbers, but basically - Glow plug open circuit, no fuel flow/pump, optical flame sensor problem and overheat and or over/under voltage.

Hi Graham and welcome to the site. To answer your questions:

 

1) You need something to reset the codes with but yes you can do it yourself. You'll need a diagnostic tool which "speaks" KW1281 or VW :D - the most popular by far is VagCom/VCDS from Ross-tech - the free version will reset the codes for you just fine but you'll need an interface cable either from their site or a cheepo copy from ebay.

2) I would say thats a fair assumption, not much else will produce the thick smoke :blink:

3) For the aux heater about 15 in total. If you get a decent diag tool you'll be able to see the ones that are logged, many cheaper versions just reset whats in the memory.

Hi there

Best change glow plug first, there are intructions in FAQ section 1 page 6 and as said remove error codes using VAG-COM that should cure your problem. :blink:

Thank you for your prompt replies. Looks like I'll need a laptop as well or drag the desktop out onto the driveway :D

Hi Lads

Brain-picking time!

I found that my auxilliary heater was not working last year. I used my workmates vagcom module to interrogate the ecu. It came up with a dosing pump error. I replaced the dosing pump with one I got from a scrap dealer(he hadn't a clue what I was looking for!). Still no joy. Is there any step by step approach to find the fault- voltages etc... Its a 05 auto 1.9tdi Galaxy. Sorry for butting in on a semi-related topic. I noticed one of 'ye had upgraded the heater so I guessed I was in the right company!!!!!

Also, I had it out on the floor- half diassembled- only because from what I can see while under the car, I have to take off the water pipes to take the top cover of the heater off.

The glow plug had wires moulded into it so in order to replace the glowplug I need to get the cover off which I'm slow to do because of the water draining out. I think its a

 

Hydronic II, D5Z-F - 12V

Any ideas.

 

Do you think replacing the heater would be a better idea?Company that sells them second-hand

 

Thanks

Hi there

 

Firstly don't forget the temperature range for the heater to kick in is below 10 deg. so unless you bridge the terminals of the outside temperature sensor plug you will need to wait till it gets colder, obviously you want to make sure it's going to work before it gets cold. To do this remove the bulkhead extension (scuttle plate) the temperature sensor is clipped to the wiper linkage behind battery, unplug the sensor then bridge the two terminals in the plug. Clear off any fault codes, start engine if everythings ok heater should start within 30 seconds.

Sorry but another Aux/Booster Heater question:

 

The heater hadn't been working (flame out code from vagcom) so I replaced the glow plug with the modified one from Ford (
