Hi everyone,

My car is an a3 8v 1.8tfsi fwd (2014)model

Never had any issues with the car until today.
Started in the morning like I usually do, gave it a couple minutes to warm up like I usually do.

After about 10 minutes of driving i noticed the coolant temperature guage was about 2 or 3 blocks above the half mark (it never ever gets higher than the half mark).

I stopped the car, there were no leaks, coolant level was fine. Fans were coming on.

After letting it cool a bit I drove back home.

The strange thing is later in the afternoon I did another start and the car maintained the temperature at normal level with fan switching on and off. I let the fan cycle about 3-4 times and all was fine. Then i switched off and started back the car soon after and I noticed the coolant gauge begin to increase suddenly. It would go to the top with 1 more led block to go.
When it crossed the mid point i thought the fan would switch on to cool it, but it did not. I put on a/c to force the fan to come on and the fan did come on but temp guage did not drop.

I turned off a/c , then turned off car, then turned the car back on and the temp was right up (one less than highest LED) , this time the fans did come on and were blowing hard. But the temp did not drop.

I did a VCDS scan and this is what came up

The intake manifold flap faults were logged earlier this year so i'm not sure if they are related to the temp. issues that were logged today.


I appreciate your help very much as my car is just out of warranty.

Thanks

Water pump internal valve not opening correctly when the engine has reached its warm up operating temperature.

It remains closed and doesnt allow the correct coolant flow.

Common vag issus, I had it on my octavia vrs
 
Thanks RSS , so are you referring to the thermostat ? Or the actual pump ?

The pump itself has a valve inside that remains closed when the engine is cold, to initially stop the full flow of coolant to allow for a quicker engine warm up.

When the engine has decided it has got to its comfortable temperature, the mechanical valve is supposed to open.

The pumps suffer with the valve either partially opening or not opening at all, causing a very slow circulation of the engine coolant.

Good afternoon.

So recently i have had the same issue, did you just replace the thermostat? as if i look for the thermostat and housing online all i find is one with a water pump. i have had an email through from audi, and just for the part and the gasket they want to charge me £250.
so i ask could one of you please help me with what parts you would suggest to fix this issue.

many thanks Joshua
