several weeks ago. Mine was a bad oil cooler. The oil has probably fouled your thermostat and it will need to be replaced. You will have to flush your coolant several times to get the oil out of the system. Expect to pay $400-500 for the intallation and purchase of a new oil cooler, thermostat, and multiple coolant flush. Also, I would schedule a second flush in a couple of weeks. You might want to consider upgrading your oil cooler to a S4 part (some minor modification needed) since it has a larger capacity.

I'll burn it when I get back to the sane north and mail it out. Unless it fvcks up, too.
