My Euro did the same thing and after several attempts to lubricate it (up to 40,00klms). The dealer finally istened to my complaints and replaced the master cylinder and it has been going strong for 3 years now with no creaking. Having said that I complained about a noisy clutch (which is a dry thrust washer) and they ignored me until it was out of warranty. I will never buy another car from them or get my car serviced there. It was with great pleasure that I bought another car from another dealer and then emailed my local dealer to tell them.
