Gentlemen - I've noticed that some used RCM's are numbered A 170 545 00 05 and embossed is Germany on the case. I've seen others numbered A 170 545 01 05 and embossed is Hungary. Note the 00 05 and the 01 05 and the two different countries. Is there a difference in the operation of the two parts? Are they interchangeable? My car is a 2005 Limited Coupe with the NA engine and auto trans. I want to get a spare RCM that is correct for my car. Any thoughts on the two different part numbers and their application?
