Air con NOT WORKING on my Audi S3 8P - Error Code 00819

My air conditioning stopped working on my 2008 Audi S3 8P a few weeks after buying it. In this video I found out it was error code 00819 which points to the High Pressure Sensor for the air conditioning system. Also known as the G65 sensor it is in quite a tight spot on the S3 engine but it was surprising how easy it turned out to be with a few tools. This fixed my air con and I am a happy chappy.

[@ilderaga]

hi,
i had the same problem, so i changed the high pressure sensor.
which i buyed from the local sparepart shop. NOT original.
The problem was still there.
We checked on gasleak, everything was ok.
i put 12 v on the compressor. was ok
after i buyed another sensor from a different manufacturer.
Still same problem :)
i cheked the whole wiring nothing strange about it.
later i ordered an original one from audi.
that solved everything !!! it took me 3 days to solve the issiue ;)
BUY ORGINAL SENSORS

[@projectfearn]

Original every time 🙌🙌🙌

Hello Danny, another fix solved,good job to find it on the reader,and it's working perfect.

[@projectfearn]

Ice cold mate 👌

[@macgregorsd]

Thanks for the documented fix! You inserted a screen shot of what looks like a cell phone diagnostic app. Can you share what the app is and buying instructions for the diagnostic tool.

[@projectfearn]

Its an OBD reader called OBDeleven 👍

[@phil_law]

Well done fella! Thats amazing! Well worth doing

[@projectfearn]

Cheers Phil ✌️

[@georgetgr7625]

Have the same issue. But my sensor is not in that location? My engine code 1.4 TFSI CAXC

[@Bionik1980]

Does anybody have similar problem but the interior fan isn't working for AC or heating?

[@waynepennock115]

Hi which OBD 11 reader do you have?

[@adzhx]

Was the air blowing warm when at the lowest temperature? My s3 ac is doing the same but I thought it needed a Regas ?

[@projectfearn]

When I tried turning the air con on the red light would not stay on if I remember right 🙏

[@thejupiter2]

Why did you spend £68 on a OEM part for a 12 year old car? Do you plan keeping it for a further 12 years? I've just paid £15 for one of these off eBay. It was absolutely identical to the original and works perfectly.

[@projectfearn]

Had bad experience with some ebay parts pal so would rather spend the extra money 😎

[@alc1212]

In my car, the same sensor seems to be leaking coolant. What do you make of that? Would replacing sensor as you did, solve the problem? Thanks

[@projectfearn]

Leaking coolant? As in gas? How do you know its leaking from there have you had the dye put in? Danny

[@alc1212]

@@projectfearn well I'm not exactly sure what's leaking out. It's green like antifreez/coolant. I just bought the car so its possible that the last owner used the die and that's why its green. But either way, the liquid coming out is green. Around the same time I noticed that my ac stopped blowing cold air. What could be going on?

[@projectfearn]

The seal may have gone in the sensor 😎

[@joshrides1967]

Can we get an update on the green fiesta.

[@projectfearn]

Coming soon mate :)

[@yusufkral7091]

hi my car econ button does not burn constantly and give cold air

[@04087140]

did you change that sensor and dident loose gas???

[@projectfearn]

Yeah there is a valve in the pipe that cuts the gas off when you take the sensor off

[@jihadgulizaxoy2434]

I have thime problem in my audi

[@fezie404]

Mate you do know the red light on aircon button means aircon is off when it's off the light aircon is on

[@projectfearn]

So the lights staying on constantly?

[@fezie404]

@@projectfearn well yea so when it'd all working properly when the red light is on constantly that means the aircon is switched off to turn it on press it untill the light go's off then air con is activated.

[@projectfearn]

Its the other way round. When the red light is on that means the air con is on. Light off means air con off

[@fezie404]

@@projectfearn it's not on the a3 models with the same dial set up lol look it up mate it's all over the net solid red means off
