hi all.

my air con light just decied to go out one day and the air con stopped. sometimes i can get it to light up but it dont blow cold air.

ive scanned it with this error showing on the air con.
1 Fault Found:
00256 - A/C Pressure/Temperature Sensor (G395)

now ive look around the net and theres tons of info on faulty sensors but as mine is reading something as its says lower limit exceeded and is reading 1.4bar am i right in assuming i dont need to read too far into this and it just needs a regas. if it had a hole anywhere im guessing it wouldnt be showing 1.4 bar. does any one know what a normal figure would be???

hi all, I went to shitefit and they regased my system, although the guy didnt fully know what he was doing with the machine but i was watching it and i know it did all the pressure vacum tests and it passed them all. it them regassed the system and it lasted 6 months unitl it stopped getting cold then a week latter back to no air con light in the car . ive scanned it and its excattly the same code and pressure. can any one suggest things i should be trying before getting it regassed yet again.???
