G'day all,

Have X3 3.0i e83 2004 and had a amber engine light come up recently. Did a smoke test and had to replace lower intake, and also AMF, cleared the codes and all was good for few days. Today i get the engine light on again and it gives me this error code 2777.DME-selftest: AD-converter
Trying to search some info about it and possible fix or cause of it. If anyone had this I would appretiate to hear some info.
