Hi All My wife took her 2008 1.3 Copen in to Halfords for an air con check as there was no ice cool air coming out. They re-gassed it and all was well for about a week, when we noticed the cold air was not ice cool again. I suspected they just recharged the system without actually checking for leaks, so took the car back and explained. They apologised and did a free check and the diagnosis was.... "air conditioning compressor leaking, along with an "o-ring" seal on the bottom left hand side of the air con system. Advise replacement" Apart from the compressor replacement, I'm not entirely sure what size o-ring or part number this relates too, so will contact them again. They couldn't source any parts with the car being "rare and too old", so am now looking for suggestions please for places to source the parts. I did a Google search and it came back with a refurbed compressor on ebay, and an out of stock new compressor from "Autodoc". I still need to source the o-ring, but wondered also if there is a schematic of the air con system available at all, which may help to see which o-ring they are talking about. Any help would be greatly appreciated. Thank you!
Hi Technik, I'm afraid I'm experiencing a similar issue. I had an air con check at Halfords in June last year, and they confirmed there was no leakage, so they re-gassed it. However, this May, the cold air stopped again. In July, I took the car to an ex-Daihatsu dealer, and they re-gassed it with dye, explaining that they could detect leaks using UV light. Unfortunately, the cold air stopped after just 5 weeks. I still need to take the car back to the ex-Daihatsu dealer to identify the source of the leakage. I did some research on Japanese websites using Google Translate and found two part numbers for the air conditioning compressor, both of which are original Daihatsu OEM: 88320-97206, priced at £431 88320-97217, priced at £427 So far, I haven’t been able to determine which one is used for European models, but from what I understand, the first one is used in earlier models. From various Japanese websites, I've found that the Denso HFC134a is compatible with the OEM part, but whether it fits or not remains the big question. On this website: コペンL880Kエアコン修理 , it shows that there is an intercooler inside the dashboard that can also leak. As you can see on the website, they've removed the complete dashboard, which must be shockingly expensive and raises the risk of something breaking, adding to the cost. The O-ring is shown in the attached PDF. I haven’t been able to find the OEM part number, but I believe it's just a simple rubber O-ring.
Hi Shahram Azimi Nobar Thank you so much for your very comprehensive reply! Some very useful information there, and appreciate the schematic attachment you provided. There is a Japanese vehicle specialist garage nearby me, and am waiting to hear back from them with a price to provide the parts and complete the repair. I also contacted an Ebay seller that has a refurbished compressor, but I need to provide a photo and label details of our existing compressor to check compatability. Will have to see how easy to find and get a photo first. I don't want to be taking the dash out as per your link, so hopefully all is good behind there. I was told to replace the "dryer" unit when replacing the compressor, but from what I see this isn't too expensive. Will follow up with the outcome after some further research. Again, thank you for your time and the details!
