Auxiliary Heater

[JRWR]

Hi again folks

 

I have VAG-COM (the free version) and so I know my aux heater has been disabled due to a number of flame-outs so I decided today that it was time to remove the heater to remove the glow plug so I could take it to a VW or Seat garage for a replacement.

 

Car jacked up and with the pictures from the FAQ #1 in hand (full colour - no expense spared! It was the company's printer after all!) I tried to match up what they showed to what I was seeing. Tricky! It doesn't help that the first, and a few later, pictures don't show for me - is that the same for everyone? Also, I have a 2004 1.9TDi so do they apply? My aux heater appears to be held in a sort of metal frame by 4 torqs screws - the frame itself is held in place by 3 10mm hex screws and one smaller one to the underside of the car.

 

I undid all 4 torqs screws and while it seemed to become loose it wouldn't drop down. So I guess I have to drop it down with the frame. Light was fading by then so I put it all back together and left it. The pictures on the FAQ (those I can see) may be helpful once I can drop the unit off the car (assuming it's the same as mine) but any other guidance would be much appreciated.

 

Cheers,

JRWR

Yes, sounds like its the same as my 2003 tdi. I found th easiest way is to...

 

1. Remove the exhaust and air intake pipes
   
2. Loosen the 2 bolts holding the frame togeather
   
3. Unplug the electrics (the hardest part for me!)
   
4. remove the 4 bolts holding the frame to the car
   

 

Once thats done you should find with a little bit of twisting about the unit will drop down. Just watch the fuel pipe as on mine it seemed to be somewhat tangled in the frame.

There are two PDF's are more photos later on in that big FAQ thread...

Thanks Mirez, that is a big FAQ thread and I've found one PDF .. will keep looking for the second one.

 

Does everyone do this at least twice - once to remove the glow plug and determine the type (and take it to the VW/Seat garage spares desk) and then again to install the new glow plug? Or is there a way to order the right part in advance and so do the job just once?

 

I'm still not sure why it's necessary to remove the exhaust and the air inlet pipe - is that just so they don't get damaged as it doesn't seem necessary to enable access to any securing screws.

There are 2 PDF's, the first I wrote and the second is in Russian (I think) and towards the end of the thread, or at least it was when I last looked lol - Its got some usefull diagrams and photos in so worth a look even if you don't speak Russian :D

 

The exhaust and intake both help support the unit which basically sits in a metal securing frame which you need to "open" to get to the heater. Without removing both pipes you can't drop the unit down to gain access to the plug - it might be possible not to remove them but I doubt it, though as with most things you'll find a way that works for you and if you dont need to... great, let us know!

 

The plugs...ahhh yes. As far as I can tell there are 3 plugs, one for the early 3Kw heater (you certainly wont have that). The "normal" one that's in the PDF and seems most common and a revised version on flying leads that seems to have been fitted (sadly for you) sometime in 2004.
