Rookie X5 Owner Confirming my trifecta issue
 

First off, I've been all over this forum for the last 2 weeks. You guys are awesome! Would never have pulled the trigger on my 03 4.4i without reading through here.

So...I've had the trifecta a few times as well. In my case, my speedometer doesn't move. From what I'm reading here, it seems that's a rear wheel speed sensor? If so I will dig in and see what's involved in the DIY fix. If it's "above my pay grade", what can I expect to see by taking it to one of the smaller shops?

Thanks and absolutely LOVING this ride! First BMW and definitely enjoying it!

Yeah if the speedo doesnt work its a wheel sensor - I forget which one but I think its right rear? Should be an easy R&R - you have to remove the wheel, caliper, and brake rotor to get to it I think - not too bad, an indy should have it done within an hour

Get the Genuine wheel sensor, not chinese aftermarket

Thanks for the reply/confirmation! From everything I've read seems to be a somewhat easy fix. I'll order 2 sensors just to have the extra and try and get to it in the next day or two.

No such thing as an easy fix especially for a newbie. Buy yourself a new plastic connector in addition to the wheel sensor. The plastic for the connector normally falls apart when you go to remove the wheel sensor from the main wiring harness. Replace three wheels sensors on my X and all three times the plastic connector just crumble when I went to unplug the wheel sensor.

Is it at the wheel and not in the differential? I my old 2wd E36, the speedo sending unit was in the diff and could get funky, fixed with a differential gear oil. As RB says, may be completely different in our E53s.

OEM
 

Appreciate the input! I've read different opinions on the OEM vs non-OEM for the sensors. What do you guys think? Looks like I found an OEM sensor for $60 vs the $90-$100 I've seen. Any major difference other than time it will last?

Sensors are at the wheels.

Sensor ordered, any info on eEuroparts
 

Ok, ordered my rear wheel sensor. Ordered it from eEuroparts in CT. They had some very positive feedback/reviews so pulled the trigger. $44 for the part, $52 total for shipping. Anyone used them before? Regardless, part is on the way and I'll make the replacement attempt when it gets here on Tuesday.

Thanks again for all the input!

What brand is the sensor.

I order parts from eeuro every once in awhile. Sometimes they have a better brand selection than FCPeuro as well as lower prices.
