Aux Heater

[pabinlove]

Hi to all

 

i've been reading lots of your post on aux heaters etc, and my brain is almost pickled, but all very useful

my question is i have a x reg 2000 galaxy 1.9tdi with 4 boys fantastic car :) , but i have read that some cars have a mk1 aux heater some have a mk2 aux heater is this true if so can anybody tell me which one i have :) , does this make any difference to repair or fixing as mine has stopped working :) (no bat mobile noise!!) only some grey white smoke? and finally is there a aux battery sure i've read that somewhere if so where is it and would that help to the white smoke or is that a glow plug problem?

 

think that is everything for now many thanks paul

If you have MK1 gal, then you should have D3WZ version which can't be normally accessed through vagcom to find out whats wrong. If you have MK2, then you may have D5WZ version of heater which should be accessible through vagcom in module 18 Aux Heater. However if you have this version of heater and still can't access heater through vagcom, you may have some wiring damage near heater (bunch of wires sticking from passenger side sill underneath the car).

 

If you manage to scan through vagcom, post your faults here and we would be able to help you out more.

Hi Paul

As your getting smoke from the exhaust it sounds like it's in the process of starting up!

 

So your next move, if your car is a MK 1 just follow instructions on here for changing glow plug.

 

If you have a MK2 you could do the same or with the aid of VagCom interogate the heater first.

 

Help is in the FAQ's of the technical section.

 

As your car is right on the change year decide which yours is, and it's helpful to quote that when posting

[marinabrid]

if you are going to change the glowplug, when you drop the heater down you will see a sticket on the end plate if its still intact then it will tell you the heater type that fitted, the glowplug is the most common thing to fail so if your handy have a go repair it, watch out though for those corroded bolts that hold the heater together.The only ones that have a seperate battery which is under the passenger seat are the top models where you can programme the heater to come on at any time of day, there is also extra buttons on your overhead clock module to set the time.

[pabinlove]

thank you for all of your advice will have a look and change the glow plug, just one more thing my wife tells me the smoke has stopped she thinks is this a sign of something else wrong or has the heater shut down to protect itself? does this mean the vag com needs to reset the heater again many thanks for your help will post codes here soon as, water pump leaking so timing belt to be changed soon as, it's also due clock just got round to 83000 miles.

 

thanks for your advice paul

Hi Paul

Yes may have locked out due to flame errors, then you will need VagCom to clear fault codes.

You may also want to check your electric coolant pump as this will affect the operation of the heater, although I think yor priority is your leaking water pump/cambelt.

[marinabrid]

dont forget though if its a mk1 with the D3 heater you wont have an additional coolant pump and the unit will not require resetting, the mk1 simply resets itself and will try to start aging next time you start the car from cold.

hi

 

the water pump and cambelt being replaced later this week, will look at the heater when that's all sorted.

I take it the electric coolant pump is the buzzing noise i hear when i turn the engine off, it runs for a short time? if that's right i only know via this forum!!!

 

Ran the car this morning on school run as on paternity and no smoke heater exhaust cold, ebay here i come for a vagcom, any one i should look out for or a specific one or type?

 

thanks paul

sounds like your run on pumps OK at the moment, there usually good for 80 to 100.000 mls then will need new brushes, or replacement pump.

I've a 2003 1.9tdi 130 - my Aux heater has caused problems for some time and have changed the plug twice (now has the upgraded Ford plug). It starts up, there's no smoke, it produces heat (hot exhaust from it) and it then stops and restarts a few minutes later and contimues doing so during the jourey even when the engine temp is showing 90. Vagcom shows the same old flame out problem. The fuel pump is pulsing away quite happily so I assume that it is getting fuel OK.

 

Any advic eon what else could be causing the 'flame out' and on/off behaviour? Someone mentioned that the coolant pumpt should be checked - any advice on where to find that would be appreciated as I have searched the forums without success so far.

 

Thanks

Try searching for either run on pump or aux pump and you will find out all about it.

I am not so sure - I have replaced my glow plug on my MK2 twice now and neither time did I need to reset any codes - Once the glowplug was fitted it just started up.

 

Maybe I was just lucky?:)

Hi to all again

 

one thing has been bugging me today i have lost alot of water due to the water pump leaking, to the point the other day my wife said that a light had come on!!

i take it the coolant to the aux heater is all the same, so would i have to bleed it in the same way i would the rad, or is it a self bleed? If not can you please advise me on how to do this.

Not long now till i get a nice bill from the local garage for the water pump and cambelt!! Cannot complain had the car 2yrs and has gone through it's mot twice with no advisories.

fantastic car for us no complaints.

 

many thanks paul

Hi

Electric coolant pump is located on the bulkhead behind fuel filter you will need to remove bulkhead (scuttle plate) held by 3 bolts to gain access, when the pump packs up it causes the booster heater to cycle up and down and can cause it to overheat, 5 successive overheats or 5 flameouts will cause it to lock out then you will need to clear the faults.

Flame outs can also be caused by fuel starvation ie, low fuel level in tank especially if facing downhill

If you have been losing that much coolant and still using car you will be compromising your head gasket albeit now or in time, even though it may not have overheated on the gauge hot spots on the cylinder head can cause premature gasket failure or even worse cracked cylinder head.

 

Cooling system is self bleeding, fill to maximum mark run engine on tick over until at normal operating temperature 90 deg revving engine a few times during this period, top up the level replace cap, take car for a run 5 miles approx then re check level when cool.

Thank you for the link to ebay one is on it's way, well i spoke to soon listened this morning to the electric pump and it's running very very slowly is this dying and needs replacing or brushes like you said, is this going to afect engine running or cause engine trouble?

In regards to the aux heater the cambelt is being replaced so that's being sorted first then i think firstly on my list is the heater glow plug then sort the pump out, vagcom, then see if it fires, is there anything else that i'm missing?

Hi Paul

To answer your questions

1. Is it dying there is usually a distinct hum from the pump when working OK.

2.Will it affect engine? in the short term no but its there also to keep the coolant circulating through engine to stop hot spots as well as circulating rear compartment and booster heater.

 

When you drop the heater down to do the glow plug carefully check the multi plug for corrosion where wiring enters plug, as this could cause problems in the future.

Hi,

I added a post not so long ago with prices and part numbers of the run on pump (additional water pump)from both gsf and euro car parts, please dont get ripped off with ford prices as these were over

[gregers]

Just like to add that replacing the hose clips to the jubilee type will help on reassembly

 

 

and a dam sight easier for removal to replace the brushes when it goes again.

[jamesey]

whats the run on pump look like?

Hi Paul

Are you using Vag Com 409.1 or VCDS lite software?

[pabinlove]

Hi Paul

Are you using Vag Com 409.1 or VCDS lite software?

 

Hi i was using the 409.1, just got the vcds lite version working long day!!!!

 

the code it comes up with when i go for module 18 aux heater is 01491 glow plug heater q9

 

so does this mean there has been no flame outs? got a heater plug on order from a few days ago as took ford galaxy owners advice as couldn't get the thing to work. Will have a go this weekend if the weather is ok
