this, this
the antifreeze is gone.
I made a few phone calls and checked on Aika, and found that this was a common problem. The thermostat was stuck and had to be replaced.

I made a few phone calls and checked on Aika, and found that this was a common problem. The thermostat was stuck and had to be replaced.
I saw that the lower guard plate was so wet
Add some purified water, find a specialized repair shop, and repair the car.
Record the number of kilometers. It’s been four and a half years.
When I ran to the repair shop, the liquid in the pot was obviously less.
Look again
Look, it’s wet again…
Start tearing it down
It seems that this third-generation EA888 needs to be cleaned for 20,000 kilometers. The last time it traveled 20,000 kilometers, the engine turned on yellow.
I think this is related to the engine tuning. The Q5 tuning is more fuel-efficient and the speed range is relatively low…
To remove the thermostat, you have to remove this first and wash it immediately.
After washing it clean, it looks different.
Keep tearing it down
steaming
Wait until the temperature drops before continuing
Remove all kinds of connecting pipes
Young master, you have worked hard
The construction environment is not ideal
Finally, it was taken out.
There are obvious water stains
Here, it’s broken and leaked.
This is the original part label
Audi, Volkswagen…
Condition after removing the thermostat
Look here again
Look again…
Look at it from all angles
Wipe this location clean and try to determine if there is a leak here.
Preliminary judgment is that this place is actually okay
This part is prone to problems, and I don’t know whether the latest loading parts have been improved.
New parts are here
Except there is no Audi logo
The biggest advantage of Volkswagen and Audi is that there are many spare parts suppliers. Brand parts and imitation original parts are everywhere, and the prices are not expensive.
INA is also a spare parts supplier
Of course it was quite good
Except there is no such thing.
Czech
I always think of an English translator from Slovakia haha
To ensure no misjudgment, replace the assembly directly.
Put it back on
Connect the pipes
Complete various installations
Add original antifreeze
Fill it up…
clean it
There is antifreeze that leaked before on the lower engine guard. Wash it with water.
cleaned up
This is the information of the online seller,”Replace the improved thermostat”…
The online seller’s information and description are clear and clear
Even the spare parts numbers of the parts were clearly stated
These prices are for reference.
There are many original parts, brand parts, and imitation original parts, and there are also price differences.
It is said that only replacing the electronic thermostat will cost more than 3000 yuan at the 4S standard.
The water pump and the electronic thermostat are two parts. Since I couldn’t accurately judge whether the water pump was hung, I directly replaced the complete set as a precaution and avoid trouble.
