SLK/R171: P0025/P0015 codes
Recently had a check engine light come on in my 2007 slk350 in conjunction with a noticeable squeak at startup (likely from a tensioner or pulley which will be addressed separately). Reading the codes I got a P0015 and P0025, and after some research found that it’s probably the intake/exhaust camshaft solenoids for both banks 1 and 2. Checked oil level and condition and they’re both looking good, anyone ran into this issue before? Just want to confirm that what I’ve stated previously is the issue. That being said, should I replace all 4 sensors (both intake and exhaust on banks 1 and 2)? Appreciate any advice
