I was able to find the Audi Webasto Decal that goes under my hood, so I got curious and looked up the Touareg and it seems there is no replacement part for the factory sticker on the T-Regg that goes inside the drivers door sill.. but with some google foo I was able to find a part number for a Transporter w/Thermo Top C in english, that also gets installed in the door sill.. you guys could use if you wanted an OEM Webasto Decal..

Part# 7E0010856E

There is another decal for the fuel door, Part# 7E0010739J

If your wanting to put those final touches on so your vehicle has all OEM identifying plates for the parking heater since it wont be on the build codes.

The only thing is that 7P Touaregs feature an Eberpacher Hydronic heater, rather than a Webasto Thermo-top.
But thanks anyway.
With regards to the Thermotop that you purchased for your Q7, they have two weak points:
  • Corroded control boards.
  • The NTC thermistor, that is, the coolant temperature sensor. It failed on my VW Phaeton and had to replace it.
My advise would be to reseal the control board casing before you install it on your Q7. I used aluminum foil adhesive tape, although somebody else have used silicon based sealants.
Should you need further advise, do not hesitate to ask.

thanks for the tips, the unit I got has a 2015 build date on it and the vehicle it came off of was very low mileage so I'm hoping its practically new.. but I've got a roll of foil tape here, might as well seal it up.. I'll have to double check the wiring diagrams, Ive got to use the T-Regg harness as they dont offer a Q7 specific one.. hopefully it dont need any modifications.

Hey so you guys know, the Audi Q7 comes with the parking heater standpipe in north america.. so if you want an OEM flange for parking heater just find a Q7 in your local salvage yard:

Mine's up and working great, no real troubles with the install until the very end and then I had to deal with Audi Component Protection, which is only something someone w/an Audi ODIS Subscription could clear, my VCDS was useless for that.. luckily I found an indy guy who did it in like 3 mins and the heater was operational... I did have to cut the plugs off the Kufatec harness and solder on webasto ones with the correct pin out, but other than that the wiring harness was perfect.

Now only 5 months before I really get to start using it heh.. oh well that gives me time to get the control unit for the remote and stuff before winter.

Basically, pull the left front wheel, pull the rear half of the wheel well liner, then disconnect hoses from tubes (plug the hoses or drain your coolant), then remove fasteners and pull the heater out of the fender. There is a peg at the rear of the heater that fits into a rubber grommet for support.

As mentioned, read this thread from the start for detailed instructions with photos!

Thanks @Scubacruiser! I've read this thread and its no use for me. This eber can be removed without all the hoses and the manual (i have all of them) shows something different from what i have (4 zone clima). In manual there is one bracket, i have 2 with totally different bolts locations. The ideea was to remove the eber and to connect the hoses between them so i can use the car during all this time. I'll keep searching.

I don't believe you can "connect the hoses between them" and rub without the heater. There is a valve in all that plumbing that gets controlled by the heater.

Since you have all the manuals, look at the Workshop Manual for the Supplementary Heater.... it tells you all about it.

I'll keep trying but i think its pretty complicated to take it out without all those hoses. Very tight place also. I have one guy who is specialised in aux heaters.
Winter is comming and its a good ideea to make it work before the cold comes.

It's not as bad as it looks. Disconnect the hoses away from the heater so it looks a bit like the photo that dreadlocks has in post #104. Disconnect the exhaust. There are only a couple wire connectors on it and just a few bolts holding the unit in. A good set of hose clamp pliers helps as do caps to minimize coolant loss. The hardest parts are getting the wheel liner out without damaging anything and dislodging the hoses from the pipes if they have been in place for several years.

I just did "annual maintenance" to my OEM heater. Cleaned internals etc and now it is back in the car but I don't get any heat to cabin. It seems that heater core for cabin is out of coolant. VAG instructions says that "all out, new fluid in". I think that I wont to do it. Yet.

How did You bleed the coolant system?

take your car for a drive with the heat set to high. This will open the magnetic valve and allow full cooling system flow. Also turn on the rest function to operate the aux heater coolant pump.

I used VCDS and found a basic test output in HVAC that ran the water pump continuously, it took a while for the pump to get all the air out, sounded like hell til it it purged it all out.. meanwhile I was burping the high point at EGR.

All clear now.

Heater is working, no air in system and cabin is warm.

It helps a lot when all fuses are in place.


Fuse sb21 was out (because of dashcam installation) and when I put it back pump started to run.

So much mess and bad words in mancave because of this. Now have to clean garage and my mouth.
