Hi. There is a strange looking unit just in front of the drivers side front wheel, on my 2.2 tdi cdx 51 plate face lift omega saloon. It looks like there is a small exhaust pipe on it as well, I would say its made from stainless steel because its shiny. The trouble is there is water dripping from it. I have had a look at it, there are Three pipes, I think Two are water (One in & One out) and one small diameter pipe. Also there is a power supply (disconnected) It must have been disconnected for some time, because the connections are very corroded. Does any one know what it is for, and what the small diameter pipe is for, and can I just bypass it ie. join the Two water pipes together. If I do this will it have any effect on any of the systems. I have asked the main stealers and they just walked around scratching their heads. Saying "der we don't know" They are about as much use as a One legged bloke at an arse kicking party. I hope some one on here can shed some light on it. thanks
