Are you "low" on oil??

No the oil level is just fine--the oil temp sensor id on the blip--meaning it doesn't work anymore

Interesting - the first Bentley reference to the oil temp P-code is on the M54 4/00+. P0197 denotes that the sensor is low, and P0198, high. So this must have been a mid-year addition.

There is no P-code for the M62. Perhaps they discovered that the M54 had an oil-temp problem, and sought to monitor it.

How about item 13? http://www.realoem.com/bmw/showparts.do?model=DT63&mospid=47587&btnr=11_2201&hg=11&fg=30

Edjack--Thanks, that is what I was a huntin--I thought that the sensor was located there, just wanted to be sure --PM

Funny, I think I remember posting to take a look at this very sensor as well...

You might call the dealer or an independent mechanic and see if there is another oil sensor besides the #13 shown in the Real OEM diagram above...

Thanks!
