Hi all,
I've had an issue on my W204 twice now, last year the A/C would occasionally turn itself off by flashing the red light three times then going off. It didn't do it every time, just occasionally. I took it to my (now sadly closed) local Merc specialist and they regassed it, they didn't diagnose a leak but said the gas was low. It's now (after a year!) started doing it again
I imagine there must be a pinhole leak somewhere, does anyone know where the system is likely to leak on these cars? I would assume hoses, connections, valves, and the condenser itself? My plan is to use a decent garage I've used before to add dye to the system and check it thoroughly myself over a few days with my UV torch to see if I can find any leakage.
