So I was getting a single 2a99 shadow code being stored in the DME. In reading a few threads on various sites people recommended pulling the VANOS solenoids, cleaning, then swapping locations. I completed that a few weeks back and all seemed well with no new codes being stored. Well today I decided to scan for codes and found I am now getting the 2a98 and 2a99 codes. In talking with a couple people they are recommending that I replace both solenoids. My biggest fear is I have a bearing ledge issue, but that seems to be more common in the N54 engines and not the N52 engines. I was wondering if anyone on this forum had some advise to share in resolving my issue before I spend $220 on two new solenoids for my 2006 E90. Thanks.
