Hi all , 03/auto/diesel 140k miles , trying to get the aircon working.Replaced the compressor and the pipe that wears through.Had the system pressurised with dye and there is a leak near the condenser/receiver-drier area.I'm trying to source all the o rings/seals to give to my local garage to complete the job in one go .I've tried my local Landy dealer/online and Rave for part numbers.Only O ring part numbers I can find are STC3176/STC3177 for the compressor.The O ring for the dual pressure switch and other pipes are shown (drawing M82 0543 PG82-84 service manual) but no part numbers come up so far.Does anyone know of a specific source/specification? It could be a bit hit and miss with an o ring kit as the garage can't test it only the aircon recharge people.Thanks ! Pete
