low oil pressure warning
 

So today driving my E70 X5 4.8i I got an error light saying oil pressure is to low and stop driving immediately. The oil level is fine and no weird sounds.

Does anyone have any experience with this? Could it be a faulty oil pressure switch?

Thanks for any insight.:thumbup:

N62 low oil pressure

I have experience with automotive low oil pressure indications in general, not particularly BMW. It is much less expensive to follow your indications and shut off the engine than to continue with low oil pressure.

I believe that the NHTSA/SAE design requirements for low oil pressure alarm indications are stringent.

Did you??????????

low oil pressure warning = stop within SECONDS and TOW TO A SHOP.

Here's a newbie Q; how does one emergency stop our BMW X5 motor
 

Here's a newbie Q; how does one emergency stop our BMW X5 motor in the likely scenarios, and what are they?

My VW TDI previous car was susceptible to diesel runaway and broken timing belts, though they never happened to me, I reviewed the procedures in my mind while starting the car for a long time. I knew that switch off, to shut the anti-shudder valve on runaway, would not lock the steering until the key was removed.

Runaway - indicated by smoke, inappropriate power without throttle. Key off, both feet on brake, no clutch!!, ABS to the side of the road.

Broken timing belt - loud ugly noise. Key off, clutch, neutral, coast to the side of the road.

How do we ensure that an overly helpful tow truck-driver, or ignorant service writer, will not roll our possibly damaged interference motor?

My career was testing small agile nuclear power plants and I got lots of gray hair learning, memorizing and being tested on emergency procedures. My reactor operator roommate would wake screaming in casualty nightmares. Thirty years ago.

If our moderator wants to fork this to its own thread, I certainly understand.

This happened to me on my 2008 X5 4.8i. I was 30 miles into a 175 mile trip. Of course, I did the mandatory pull over immediately and stop engine to investigate. I quickly determined that I had not lost oil, the engine was not making collapsed lift noises and thus concluded that the oil pressure sending switch was at fault. I continued on my way while doing rpm experiments. Above 2500rpms, the sender would work fine. I replaced the sender yesterday and all is well again. My 2004 545i needs its third sender due to leaking oil and making a mess.

Oil pressure switch most likely. Good insurance to replace this switch every 100000 miles. If this switch blows you will lose all your oil in about a minute. I have 107000 miles and I'm in the process of changing this switch as I see fluorescence from some Tracer dye I put in my oil. Also seeing leakage around the oil cooler thermostat housing.... The switch is located under the vacuum pump. need a deep 24mm socket to remove. very easy... Always use OEM parts, this is a critical item. I recommend a tracer dye as you will be guessing where leaks are coming from on the 4.8. They are very easy to spot with the Tracer dye and a blacklight flashlight.

With low oil pressure being one of the most devastating failures possible, I am surprised people suggest 'its just the sender'.

While that might be true 50, 60, 95% of the time, until it is definitively diagnosed do you risk a $20k motor with such a guess?

You can lose oil pressure without an oil leak.

Is there a reliable way an owner can assess this on the side of the road?

NO. There can be a variety possible causes. Have it towed.
