Hi All,
I am currently having some air conditioning issues with my Audi A3 and was wondering if anyone would know what it could potentially be!
The problem seems to happened after the battery died and it was jump started (at least i think this is when it happened)
Initially when i pressed the aircon button it would turn straight of, i ran a code checker on it and i got a readback of low pressure (B10ABF0). as i had the car re-gassed the year before i read online its common for the pressure sensors to go bad so i replaced it and still had the same issue, i then brought the the AC pro regas from Halford and the pressure reader thinking this would also seal any potential leaks.
on starting the car and reading the pressure i noticed it was in the middle of the Green (just the right amount) i Still then topped it up to the max green. the air-conditioning light then stayed on, i thought result! however there was still no cold air 😞.
i also checked the compressor and it seems to be spinning ok, so i thought to take it out for a drive to see if maybe driving it would help..... it didn't
After getting home i noticed the radiator fan was not on even after a hard drive which it normally does, it also wasn't coming on when i put the air conditioning on. i tested the voltage to fan plug and there was current going to it.so my initial thought was a faulty fan i took the fan out of the car and plugged it into a friends a3 and it came on.
i then tested the voltage to the compressor plug and there is voltage going there - so iam thinking the compressor is bad i don't want to replace if its not faulty as it can be expensive.
Does anyone know what it could be?
P.S there are no codes coming up and i have also checked the fuses and they seem all ok. i tried to find the fan relay as well but can - (its not under the support arms).
Any help would be much appreciated
