    I get my car back today. They say they test drove it 3 times trying to get the oil temp overheat warning to come on; to no avail, of course. I pick it up and drive it home and guess what comes on before I even get home (~5 miles away)? The f'ing oil temp overheat warning. I wanna just scream at them. So ridiculous. This is why I, and others, hate dealing with the service department.
    Perhaps they are lying to you, but then again maybe they are not. It is possible they did test drive it 3 times and the problem did not occur. My point is just that intermittent problems can be frustrating for everyone involved. I wish you luck.

    It happens every time I drive it more than 5 minutes. They're either retarded or liars. Or both.

    I had mine going off on the way to the dealer - So when I pulled in I didnt shut the car down - I ran in Grabbed my Service Writer turned on the A/C, and BAM 270...280... DING DING - But they still cant fix it!! I've even contacted Cadillac directly, and they have been no HELP at all.

    re: Damn! High Oil Temp and alarms? Here is a fix for it (page 7 post #98).

    So does anyone know what is really causing this behavior?? I can reduce the behavior by cleaning the ground connections, etc., but I can't completely eliminate it. I also can turn the car off and right back on and the issue will go away again. (That tells me that the temp isn't really the temp at that point because it goes from 325 (ding, ding) to 210'ish simply by turning car off and on.)

    What else can I do here to get it to go away? (How do I know when the sensor itself is bad? Is that DIY changeable?)

    Same deal here had it in 3 times for same thing, last time they did the wiring bulletin and changed the oil temp sensor, it is a little better but still not right, running 240 and with AC and hot day in the 270 range, still way off.
    I don't know what to do either at this point! Cant understand why they cant fix it if so many cars have the same problem, mine is an 05. BTW the service manager drove with me and observed the crazy 20-30 degree changes in a matter of seconds.

    re: Damn! High Oil Temp and alarms? Here is a fix for it (page 7 post #98).

    I'm going to bump this oldish thread. Anyone have any updates on the issue? Anybody found the winning solution?

    My '05 has the same issue. I'm going to take it to the dealer to have it looked at but I'm not hopeful.

    This seems like a grounding issue: the change with the A/C being turned on and off, the improvement with cleaning the engine block grounds, large reduction in the temp reading by just turning the ignition on and off. As discussed earlier, it sound like a floating ground on the temp sensor, and the voltage difference between the temp sensor ground and the real ground slowly increases as the car is operated.

    Do any 06 or 07 V's have the problem?

    Perhaps we could examine how their oil temp sensor is wired.

    Wow My Old Thread... Still have not fixed the problem.... Its actually going back to the dealer tomorrow for this issue again.

    I know for sure its electrical. It's also linked to the Tail lights (while Braking), and after the car is nice and warmed up 30+ mins. But it sure is anoying!!!

    Some V owners might have the same issue, just dont even know it.

    It only happens when I've been in Traffic for 30+ mins.

    Driving for 30+ mins, sometimes coming to stop w/ AC On.

    So If your driving short trips, and not using AC, etc. You might never get this issue.

    I can make it come on now though... Since I've dealt with it for soo long. Just wait for the Car to Warm up (30+ mins) Hit the Brakes, Turn on AC, Hit the Window Up Buttons, and WA LAH!!! Ding Ding Ding - Pisses me OFF!!

    I had this problem all last summer... too lazy to take it in... first "nice" day this year with a 1 hour drive... trouble kicks in...

    I really need to get off my rump and just take it in... I have started a nice laundry list of warranty items, so it will be "worth my while"...

    Where is the sensor? I may end up unplugging it. But I wanna clean up all the connections first.

    I was just thinking about that last night. Now that I'm watching it, it seems that it's usually just a little high. I wouldn't wanna have this problem with a cooler, cuz the temp may be too low, and I wouldn't know about it.
