I have a 2002 ( '52) tdi/se fitted with a webasto heater.....great for those frosty mornings.until it packed up !!!!!!! I have had the car to several webasto agents all of who scratched their heads and came up with blank looks !!!! This was the same result from Audi dealerships with most of them stating ''have you fitted it yourself??'' I have spoken with audi tech people and webasto and this is where the problem is;-

The glowplug/pin in the heater is faulty and will not ignite the diesel;-

If i went and bought the same webasto thermo top heater for my narrow boat the faulty part can easily be replaced by a webasto agent £ 103 !.... but because webasto supply this heater to audi to be fitted at the factory the part numbers are different ! and no one can tell me if the audi/webasto part numbers are the same article !!!!

Audi have quoted me just short of £600 for supply and fit of an igniter unit which inlcudes the faulty part ( not available as a seperate unit from audi )

I have the audi part number - 4E0261433C.......but NO-ONE can tell me if this is the same as webasto part number - 92995D !!!!!!!

i AM ABSOLOUTELY FUMING WITH AUDI AND WEBASTO....what an aboloute shambles.after care is nil unless you want to spend hundreds of pounds !
does anyone have any ideas or suggestions on where i can get this repaired.
Live near to Skipton in North Yorkshire. thhanks :mad:

Sorry to hear of your problems and unfortunately, I can't shed any light on the cross-correlation of part numbers.

What I can tell you though, is that the part number you have is valid and the dealer price is £263.72, that is before any discount you can get.

I have the full exploded diagram of the heater showing the insert and it looks like it should be user changeable.

As these heaters were only fitted to the earlier A2s, it's not surprising that a dealer was ignorant of it, but Webasto should be able to tell you what they supply to Audi.

Keep us informed of how you get on.

Cheers,

Webasto

Hi Moorlander,

Do Webasto heaters start to go faulty after five winters? I have a 2001 A2 and found that the Webasto aux' heater was not working at the start of the 2006/2007 winter. A year later, it is still not fixed, so I would be interested in reading about how you get on. The winter weather here in Northern Ireland is quite mild, so the Webasto was not called upon too often. I have been able to get by, by making sure that the inside of the windows are spotlessly clean and the car is garaged overnight. I also keep the climate control set to 19 degrees when I am stuck in slow moving traffic, as setting it any higher causes the engine temperature to drop slightly, when it is freezing outside...

When did they stop fitting the aux heater as I am sure my 2004 has it - below 5 DegC within 2 minutes I get warm air from cold
 
Hi Moorland
I can understand your frustration with Webasto but this is typical for Original Equipment suppliers whose hands will be tied by their contract with Audi.
If you have not already tried them, there is a slight chance that Webasto at Doncaster may be able to help. Maybe if you took the car there they would strip the heater down and replace the faulty parts, assuming they are not unique to the Audi spec heater(very unlikely)
http://www.webasto.co.uk/company/en/company_locations.html
I have a contact there through work so if you don't mind waiting a couple of days I will get in touch and check it out (hopefully he still works there) No promises but it may be slightly more fruitful than you 'cold calling'

Cheers Spike
 
The later vehicles (A3, A4 and A6) did away with Webasto and fitted a 1kw!!! PTC electric unit in the system - result INSTANT heat from the vents in TDIs in cold weather. MUCH better than the Webasto although a different variant is still available for cold climates to aallow PRE heating of the coolant system and interior by remote control.
 
Hi Moorland, more info on the A2 Webasto heater -
As expected, the unit was developed by Webasto-Germany to an Audi spec
It's likely that all the internal parts are standard Webasto but the unit has been packaged to suit the A2 installation so may have some external differences.
There is no Audi / Webasto parts list cross reference available to Webasto UK dealers.
Standard heaters have a 'W.Bus' 2 pin diagnostic plug for fault code reading by the Webasto dealer. I don't think this is fitted on the Audi version so fault codes can only be read by the Audi dealer or VagCom user.
There is a small fuel pump (under the car, somewhere near the fuel filter I think) which supplies the heater - it's worth checking the fuel delivery
The heater is controlled by an ECU which can shut everything down if a fault is recorded on any part of the system. This could be anything from a temp sensor or the fuel supply pump to a wiring fault. Just because it won't fire up, it does not mean the glow plug igniter unit is duff.

First step is to get a diagnostic scan. If this points to an internal fault with the heater unit, the unit needs to be removed from the car. Doncaster don't have repair facilities so you would need to take it to a dealer (David Peel Auto Electrics was suggested)
As indicated above, it's 99% certain that all internal parts are standard Webasto so they should be able to fix it.
Not sure if I am the closest VagCom user to you but I would be happy to do the diagnostic scan if you care to drive over to Richmond (My postcode is DL11 7HU)

Cheers Spike
 
more on webasto

funny you should mention the fuel pump.......when the heater was working there was a slight knocking noise coming from under the floor pan ( exterior) and now there is nothing !! will have a look.

as for david peels ---------they had the car nearly three hours.....sat and waited-------and waited -----waited------they told me it was the glow plug---------but hadnt done one before-----would have to seek advice----------3 weeks ago and heard nothing since !!!!!!

:mad:
 
I think I've got Webasto woes too. The car interior doesn't heat up very quickly in these cold mornings. Having only had the car a short time, and not having read the manual, I was surprised, on switching the car off on one our first cold days, to hear a whirring noise from under the bonnet, the smell of diesel, followed by what looked like white smoke coming from under the o/s front corner. Panic ensued as I thought the thing was about to ignite! It was only later I came across A2OC and found it had a heater built in and this eased my mind somewhat (well done A2OC!) I guess this tells me that the diesel is getting to the heater but not igniting. Is there a way of telling where the fault lies? I don't have access to VAG-COM.
 
webasto heater

you need o get the vag-com test done......i went to my local vw dealership and they were happy to oblige.......be prepared for getting zero response from audi and the stealerships !! not had any positive feedback from any of them yet and still trying to get someone to repair it...even webasto agents havent got a clue !!

glow pin and burner assembly - £268 plus vat from audi
same part from webasto £108 plus vat

problem being neither can say if parts are compatible and no one can quote on fitting charge as no dealer appears to have fit/replaced this previously !!!

best of luck !!
 
i think dealers should be able to qoute even if theyve not done the job before as the software they use can generate labour times

Hi dilbert

From your description I think the Webasto heater is working as the built in fail safe system should prevent it running if there were faults with the igniter system. On a freezing day, with the Webasto working, the cabin still takes several minutes of gentle driving to get warm which is about half the time it would normally take. Note the Webasto is switched off when either the Econ or Off buttons on the CC panel are depressed.

As the climate control system blends hot and cold air to maintain the selected temp, a faulty temp sensor or motorised air distribution flaps could be the cause of the 'cool' cabin temperature. If you are convinced something is not right, a diagnostic check is the best way forward.

Cheers Spike
 
Thanks - I'll keep an eye on it. I was aware of the Econ setting disabling it. I don't get to drive it too often but her indoors (hates cold and dresses like Nanook of the North) says it begins to heat up within 3 miles of starting. I read another post that suggested the cabin should start to warm almost immediately. Perhaps I was just expecting too much?
 
Faulty glow plug

Just been told by my local garage that a diagnostic said that the glow plug in my diesel cabin heater was faulty. Any one know where to get a replacement from and how to change it. Please don't suggest the Audi dealer. I'm never going near them again.

Regards....
 
Unfortunately, there are no readily available spares for the Webasto heater fitted to your A2! This is not the most helpful of replies, but I fear a strip down and rebuild is the only option here.

Sorry,

Cheers,

Mike

Hi Alve, welcome to the A2oc
As you probably read, Moorlander has similar problems with his Webasto heater. I have spoken to Webasto on his behalf and can confirm the unit has built-in diagnostic capability. Aftermarket heaters are fitted with a 2 pin diagnostic plug but the Audi version appears to be linked into the car diagnostics and can only be tested by a VAG dealer (or with VagCom) Problem is that Webasto dealers have no technical data on the A2 installation or info on its removal while as Skipton said, Audi dealers have no internal parts available or any idea how to fix a broken heater.
Although not confirmed, its 99% certain the basic A2 unit is identical internally to the standard Webasto heater.
If you are handy with the spanners and can remove the heater unit (you would need to make up a bypass tube to connect the coolant supply and return hoses and blank off the fuel supply if you want to use the car) - then there is a good chance a Webasto dealer could fix it.
For info Moorlander had the diagnostic scan done at a VW dealer who identified the problem as a faulty Glow Pin.
I'm interested to know if you are able to remove the heater and take it to a Webasto dealer as suggested

Cheers Spike
 
Dear all,
Thanks for the replies.
I had the diagnostic scan done by a specialist VW garage (not the Audi dealer). He assured me that the glow plug was faulty, but couldn't do any more with the version of software he had. It may take some time before I pluck up courage to remove the heater but when I do I will let you know.
Once again, thanks for the replies.

Regards..

John...

Webasto aux heater

Hi Moorlander,

Thank you for reporting back with your good news. Would you be willing to tell how much this cost? (PM if you prefer not to post) I might let my local dealer have a go if I thought their price was competitive.

John.
