Thanks for choosing Just Answer . I'm Wolfgang here to help!!

I am confident we can resolve your problem together. Please
understand that I don't know your skill level. In most cases when you have a problem
with the way the vehicle performs, specialized tooling is required to acquire computer
data/information or engine testing results. We didn’t build these complicated vehicles; we
just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the
vehicle either, so it may take a few replies to get to satisfactory results. Note there may be an issue where the complexity of the issue will require a Premium Service. This service will be an addition to the normal question cost. Usually it does not come down to this but keep in mind!! I am also going to direct you with the fastest, easiest and most common things to check first. Please be
patient and permit me to do what I do best.
I also try to give all of the information you may need, expecting a “positive rating” in
return. I will also continue assisting you after you have rated me, if necessary. If there
is any reason I cannot get a positive rating, please let me know why “in advance”, so I
can go another direction for you. I am sorry you’re having this problem; I’ll help you
through it.
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail.

now if you have the car running and you pull the hose back with the bleeder hose till its open then raise the rpms to 2000 does the coolant spit out of the hole?

if not yet stab the trottle a couple of times to 3000 to idle then monitor the coolant out of the bleeder hole!!

please do let me know!!!

thanks

some coolant spit out and i’m doing the bleeding but still less heat coming out. Is there any type of heater valve or something in my vehicle?
Customer reply replied 8 months ago
Heater core and heater core hoses are hot. But still blows warm, no heat at all. It’s like fan blowing..
Audi Mechanic: Wolfgang, Audi master tech replied 8 months ago
There is no heater valve. Did you flush the coolant out and new is used?
Out of the bleed hole should be a stream

Customer reply replied 8 months ago
Yeah i put new coolant on it and bleed it then the air starting to come out then after its solid so i assume no more air in the system and still both hoses are hot but still no heat coming out
Audi Mechanic: Wolfgang, Audi master tech replied 8 months ago
Did you scan the climate control for codes?
Ask Your Own Audi Question
Customer reply replied 8 months ago

Audi Mechanic: Wolfgang, Audi master tech replied 8 months ago
