Cleared the codes out and the CEL came back on 30 minutes later. Today after changing the oil i noticed a very loud vacuum leaking sound. Sorry I don't have a camera to show this better.... The front of the engine there two vacuum hoses coming out of the lower part of the intake manifold which go into a sleeve together and come out and into two separate stitch things.... The one on the lower right has semi disintegrated at the connector. Will replace tomorrow and see where it leads me...

Sorry about the lack of knowledge on the terms here.... W126s are more my speed. Luckily this is the first headscratcher I've had with the W210.
