So, changed my oil yesterday and found that both my intercoolers have oil residue and staining at the bottom - brilliant Seems like another item to add to the list of substandard parts fitted to our RS6's.
I am now unsure what best to do. I imagine these intercoolers are repairable, probably the best way by sending them to a radiator specialist for re-welding, but as my car runs considerably higher than standard boost due to the MTM568 conversion I wonder if they would even hold up then. The leak is visible at the bottom seams due to the oil stains but I can see no reason why the top of the intercooler would not be leaking as well.
Obviously fitting new OEM intercoolers is a (cheaper) option but to be honest I am not a great fan of fitting new parts without looking at the available upgraded options. Also, I am not keen on fitting parts that will likely fail again...
I know there are 2 other alternatives available - Wagner and Sportec, but sadly my budget cannnot justify these at the moment.
I have also seen a few RS6's on the internet with proper front mount intercoolers and there is a kit available for the 2.7TT Audis, but I doubt this would fit the RS6. I would quite like to go down the full FMIC route as I have done 2 custom installatons in the past with excellent results on my Legacy TT and my Saab convertible. Does anyone have experience of FMIC on RS6? Can anyone offer advice? Is there any other options I should also consider here?
