Sir,
Firstly, I really appreciate your help, thanks a lot.
I took mine to the authorized dealer. Techincian says (as you mentioned)that changing the thermostat is a must. The bad thing is the hurrible cost : 800$, 130$ for the part+670$ working.
I'm really mad because a part like this shouldn't be repalced before years and years.
Warranty is only up to 37000 miles or 3 years so I have to pay for it.
I asked a good local shop technician and he said replacing Q7 thermostat takes around 5 hours working unlike other cars.
I was expecting to replace it for free because I have nothing to do with this issue, it's the fault of Audi engineering.
I drove lexus 2002 for more than 200,000 miles and before that Camry, Honda Accord and never had this problem.

Did the Audi tech check for any codes?
did it come up with Thermostat code or a temp sensor G62 code?

It's very hard to be a German car fan when you hear of these types of issues. If the engineers would devote a little more time into ease of access and a little less time on making things as complicated as possible we would all be better off. I changed the T-stat on my Sea Ray boat which uses a Chevy 305 block and it was about a 15 minute job.
Hell, a starter on a Boeing 737NG can be R&R'd in about an hour and an entire engine can be exchanged in about 4 hours.

smith2010Q7 : soon I'll report you.

An issue like this is no doubt has to be a recall. I never been in traffic in a hot weather, and I always drive it for a short distance.

Audi charged me 370$, they fixed it with ''Recall Number: 15V019000''. Now thermostat gauge seems little bit lower than usual.
thank you all for participating here.

Few days ago I changed all 4 tyres, I bought Continental ( the one made in Germany not Czech) instead of pirelli. More comfortable than Pirelli. I feel like I changed shock absorbers too.
