Well, my New Plus Four radiator sprung a leak today, just 680 miles on the clock, front passenger side just below the rack and pinion.
Sorry to hear that P8mog mine is now at the dealer for the second time in a very short time with a leaking radiator apparently it has something to do with the radiator rubbing against the intercooler. The dealer is now looking with MSC for a permanent solution because it is a lot of work changing them. They warned me it could take some time 🥴. Let's hope they will find a solution fast.
