A/C Recharge / R134a Charge Specs
Just had my 3yr old S A/C recharged at Kwik Fit (£45 versus £160 at Mini dealer). Print out tells me they removed 125g of R134a and 20ml PAG oil. They then recharged with 415g R134a and 30ml PAG oil. Print out also states no leak detected.
I cant believe it is normal for an A/C system to lose 2/3 of its R134a in 3 years (although Kwik fit tell me it is). I know R134a leaks more than the old R12 gas used to but is this kind of leakage normal?
Does anyone have access to the Mini specs on what the correct charge rate is (did Kwik fit overcharge it) and what is their spec for leakage (I am an auto engineer working with Ford and I know Ford have a leakage spec so Mini must have one)?
