2014 A5 Premium Plus Cabriolet Quattro 2.0T
I'm the original owner of a 2014 A5 2.0T, with a CPMB 2.0 turbo 4 cylinder engine, now at 66,000 miles. I've long been aware of various older Audi engine issues, oil consumption and cam chain tensioner failures with this engine type, but I've never seen specific correlation of either of those issues with the generation of engine in my car, built late in the 2014 model year. "CPMB" is a code you can see on the white computer printout sticker underneath the trunk floor and I think elsewhere on the car, the "B" meaning that my car can burn E85 ethanol (but I've never used that; it's virtually never seen here in the PNW). So I have various curiosity questions... Am I right the CPMB engine has a better reputation than earlier versions? My car still gives virtually zero detectible oil consumption between changes I do every 5,000 miles. Do problematic cam chains give audible or other symptoms of problems, with some amount of time to react, before catastrophic failure? When/how so? (My car sounds great at every startup and during all driving, I think just like it did when new.) Is other preventive maintenance advisable, other than the normal maintenance I'm doing now?
