Just killin' time on a Saturday evening watching Audi repair videos and stumbled upon this one. I wasn't in the best of moods but this video caught me so off-guard and made me laugh SO freakin' hard. I owned a couple Audi's MANY years ago (well before Audi became notorious for being over-engineered money pits) and even then I can recall flipping into fits of rage over repair jobs. Oddly, Audi's remain on my list of favorite vehicles despite those frustrating experiences. You have to admit that when they're running good, they are awesome vehicles!
I know this video is old but it helped a lot when doing the repair on my car. To sum up the cluster fuck that is the a8 d3. when the car reaches 90*c it opens the termostat which redirects its coolant to the webasto unit's cutof valve (not active when heating activated) then it passes trough the webasto with no opstruction to a metal pipe near the right fender and goes up as a direct intake to the solenoid valves. the valves then (i unjacked them to get 100% open valves) pass trough the coolant via secondery magnetic pump to the heater cores *yes 2 of them. So it goes in the solenoid with a large hose and splits of to 4 litle hoses, on the left side of the solenoid its the passanger side (lhd model) and the upper hose is the return line and the bottom is the feed line, the same goes for the drivers right side. So here is where the trouble can come up, you can get heat up to the cores, but for some reason they are ice cold a second later and that is due to a air pocket ether in the cores (you have 2 bleeder screws for that) and one nasty litle bleader screw that is behind the engine in the middle of the car. (when you look at the turbine 3.0tdi and look at the firewall and 30 cm down you will se a T pipe that has a bleader screw, what happens is that air gets traped there and because the coolant system is massive, you dont have a vacum there and you dont have regular circulation of coolant. when you air that one out, you should get a regular return of coolant which the water pump it self creates and thus you have heeting. Hope this helps someone.
Hi, my car does not give any hot air. I scanned the car and it shows a fault with the heater valve. Is there anything I can do to fix the existing heater valve or will I need a new one
" this car is overly complicated, as soon as i fix it im selling it. And gonna get a tesla" AHHAHAHAHAH! Then you wont have to fix the tesla since tesla wont sell you the parts you need . :p Comedy gold

Yes. Was GTG after this.
No solenoids were hurt in this video

Hi, I do have same issue with my 2008 3.0 TDI Audi A8 ,have you fixed the issue? What was the cause? Thanks!
@@paulroman7587 there was no heater valve in my car. Previous owner took it out to bypass it. There was a issue with my car related to the head gasket
