Aux Heater ?

[chrispb123456]

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 (

Yes but the EBBY heater controls the fuel pump so the pump wont work unless the heater tells it to? What I want to know is all the options where the heater would stop the pump ie Overheat? Electric Water pump not working? Glow plug failureetc etc?

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 <u>is</u> 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.

Hi Kev

I've just had similar in my 06 1.9TDDi 115BHP Galaxy Mk2. What did you do to solve your problem of fumes, was it to change the dreaded glow plug?

Finally decided to do something about the smoke billowing from the auxillary heater exhaust after the other half got pulled over by the Police today, they thought she was on fire!

 

Phoned the local VW service department who initially told me this was normal at this time of year. After explaining how bad it was they quoted me

Open the bonnet, locate the pollen filter (its on the passenger side just under the window deep back in the scuttle tray) In front at the top you will see dangling a small cylindrical can (about the size of fluorescent starter)attached to 2 wires. Thats the thermal switch used to control when the aux heater comes on.(some operate at +5C, some at +10deg C)

Pull the plug off and.....no more aux heater.

 

 

It takes a fair bit longer to heat up without the aux heater if the ambient temp is below freezing and if the ambient is really low (< -5 deg), the engine may not even get to normal temp without the heater. But it wont harm the engine to live without it.

 

 

Oh.....thats

The pump has two pipe connections, the inlet pipe is the one with a union nut, unscrew the nut and the filter is there in the pump body.

Where exactly in the car is this pump - sorry want to be sure I do it right.

Hi there hope you can help me Ive read all the posts on the aux heater but cant seem to find the answer to my problem which is a dead aux heater.

Ive got a 2004 130 tdi galaxy Ive changed the gliow plug and read the fault codes and expecting them to be flame out but its saying OVER TEMP SENSOR (G189) 01489 STATIC INTERRUPTION, now I didnt read the fault codes before changing the plug so I dont if they where there before but Ive checked eveything I can fuel pump and other connections.I was wondering if it could be the aux water pump or somthing inside the aux heater.ANY HELP WELCOME.

This sounds like water is not circulating through the heater - so it overheats rather than circulates cooler water through it. check the auxiliary electric water pump AKA 'after run pump' is working. Get to a quiet location and listen for the hum from behind the dash in the engine compartment as soon as the engine is stopped. Standing at the front of the car, with ENGINE JUST TURNED OFF put your hand over/behind the fuel pump and feel if the pump (held in large rubber rings) is running. It is designed to run for about 90 seconds or so after shutting down the engine. It also starts up about 90 seconds after starting the engine but you won't hear it.

 

The pump is fixable (usully worn out carbon brushes) if you are a patient person prone to fiddling with very small awkward things. If you replace it can I have your old one because I seriously butchered mine doing a rushed repair job on the brushes.

Thanks for that - I got my heater working over the weekend, used a new glow plug from ford (one with wires attached), replaced the filter/gauze for the glow plug, and cleaned the combustion chamber and replaced the gaskets. Did not bother with the fuel filter in the end, everything worked after clearing the flame out codes with vag-com - car nice a warm quickly now, many thanks to all the useful posts here.

Thanks for the reply Dave I went down euro car parts and picked up a new pump on the of chance mine is duff but I will try test it but I do seem to remmember hearing something running when I switched off when I first got the car 12 months ago but wasnt aware of this pump arrangement and now thicking about I havent heard it So I reckon its had it, THE CARS DONE 90,000 I will let you know how I get on. By the way the pump part is

BOSCH PART No 0 392 020 073

 

EURO CAR PART No 201 44 0180 ADD WATER PUMP VARIOUS MODEL

I read somewhere that the pumps fail at something like 80,000 miles so it's very likely yours has the issues. That's a good price you found one for too apparently.

 

 

All the best with it Andy.

I thought so I use them alot good price on OE parts I mean the additional water pump came in a bosch box with the audi badge stamped on the pump body so Iam happy. Iam going to try to fit it on friday so fingers crossed will let you know how it goes.

I came on here looking for heated mirrors info and started to read this thread with interest as my 04 tdi ghia used to take an age to get warm. Now thanks to this i got a new heater plug followed ivor's pics and i now have a nice warm galaxy so warm that the wife is complaining its now to hot(cant win).

cheers

does anyone know if a mk1 has a run on pump ?

 

also why previous owner would short circut the water hoses to the rear heater to bypass it?

Probably a leak on the pipes or heater matrix

Well I fitted the new run on pump which is working perfectly but the code reader is still say over temp sensor so I was wondering if it could be anything else,metering pump,fan or even a faulty sensor. Abit stuck at the moment what I will do is strip the heater down again and double check everything,stumped is a under statement any advice welcome.

 

ANDY

[Dave-G]

That's stumped me I'm afraid Andy and I now feel a bit guilty unless you established the older pump definitely wasn't working (did you get my PM about your old pump?)

 

If you code read the faults I'm assuming you cleared them. Does the blower fan in the heater work ok? The next thing I would look at after that as you suggest is the sensor.

 

Is you code reader vagcom - can you read the measuring blocks? I find sometimes the thing dont want to work but persist in clearing the codes (multiple flameouts) then it's all good again.

[chrispb123456]

Hi Andy

It does sound from your previous posts that you are only reading your fault codes and not clearing them, the heater is probably locked out and you need to clear the faults codes before it will start

Any chance of reinstating the photos?
