The threads on a/c problems seems endless so I hope I don't bore everybody with yet another one, but my problem is becoming very frustrating and, potentially, expensive and I'd welcome any input that might help narrow down the problem.
Firstly, the car is a UK registered, 2006 Golf GT with the 2.0 litre PD engine developing 170hp. It has had the DPF filter removed and chipped accordingly and now developing something in the region of 220hp. It has been in this state for 3½ years. Six months before the re-chip/DPF work the a/c compressor was changed due to the original being seized but, significantly, the system was NOT flushed at the time.
Last summer I noticed that the a/c wasn't working - it doesn't usually get THAT hot over here in the UK!!) and it transpired that the compressor had, again, seized - some have suggested because the system wasn't flushed with the original change. However, now knowing that the flush was important I paid for a full system flush, new compressor, a new condenser and receiver/dryer and all was well again.
Three months down the line (only THREE MONTHS, note) exactly the same has occurred - except this time the compressor hadn't seized but the three plastic lugs that transfer the drive from the pulley to the spindle had broken. The supplier decided to put it down to a faulty compressor having checked the operation of the cooling fans which he suspected might be at fault.
Now, only THREE WEEKS from that replacement it seems the same has happened again. I haven't had the plastic links checked yet and it's possible THIS failure is unrelated to the previous ones but somehow, I doubt it.
Has anyone any suggestions as to what could cause this problem. When the latest failure occurred it was noticeable that immediately before the a/c stopped working completely it was putting out exceptionally cold air - noticeably colder than usual and, coincidentally, on quite a hot day (25 deg C - hot for the UK!!). The car was parked for approx 90 minutes and on a restart there was no a/c.
The shop that did the most recent work have said they have never seen failures like this and want the car for a few days to diagnose. Any pointers to help them would be appreciated.
Regards
Dave
