Go with the OE builder and save some $$ and you should be golden. Hopefully not much else is none functional.

Yes its true that they rarely ever go out but I have seen one on a 540i that went out with a fellow enthusiast's car and he had tell tale signs and yet he chose to ignore the warnings (repeated codes of the same). When it finally failed it left him stranded on the highway. I on the other hand would like to avoid such an occurrence and be proactive. I have ordered the VDO unit from autohaus which is the same manufacturer for the BMW branded unit. Thanks for the insight Stephen
