BMW E46 ABS Sensor 34526752683 – Rear Left or Right ABS Wheel Speed Sensor for 3 Series E46 320 323 325 330 M3
BMW E46 ABS Sensor 34526752683 – Rear Left or Right
This BMW E46 ABS sensor is a rear wheel speed sensor sold under reference number 34526752683, and the supplier lists it for the left or the right rear wheel of the 3 Series E46. One sensor comes in the pack. Easy Life Markets sells it for owners who have an ABS or traction warning on the dash and a fault code that points to one of the rear wheels.
The E46 is now old enough that rear sensors fail regularly. The sensor sits in the rear hub carrier where it is heated by the brake, soaked by road water and shaken for years, and the lead becomes brittle. When the signal drops out, the car disables the anti-lock braking system and the stability functions that depend on it. The normal brakes carry on working, but you lose the electronic help on a wet or loose surface.

What Is Included
- 1 x rear ABS wheel speed sensor with its lead and plug
The supplier's data sheet describes the contents as a "repair kit" with one item in the pack. In practice that means the sensor itself. A mounting bolt is not mentioned, so reuse the original.
Vehicles the Supplier Lists
The listing title names the BMW 3 Series E46 in 320, 323, 325, 330 and M3 form. The supplier's attribute list is more specific and gives these three entries:
- BMW M3, 1998–1999 and 2001–2005
- BMW 330Ci, 2001–2006
- BMW 325Ci, 2001–2005
You will notice the two lists do not line up neatly, and the supplier itself says its compatibility data may not be fully accurate. The E46 also changed its ABS and stability hardware during production, and different versions use different sensors. For those reasons, please match the part number and do not rely on the model name.
Three Ways to Confirm the Match
- Old sensor. The BMW number is printed on the lead or the plug of the original. You are looking for 34526752683.
- VIN lookup. Put the last seven characters of your VIN into a BMW parts catalogue and open the rear ABS sensor entry for your car.
- Ask us. Send us the VIN and we will compare it with the reference number before you pay for anything.
Owners of right-hand-drive cars should take extra care, as the supplier points out that part numbers can differ on those versions.
How a Bad Rear Sensor Shows Itself
- ABS and traction or stability warning lights stay on after start-up
- The brake warning light joins them, often in yellow
- The lights come on at a particular speed or after a bump
- Unexpected ABS activation when braking gently to a stop
- A stored code for the rear left or rear right wheel speed signal
Read the code first. A scan tool that can talk to the ABS unit will tell you which corner has the fault. If the code keeps returning after a new sensor, look at the wiring back to the body plug and at the toothed ring the sensor reads.
Fitting It
- Jack up the rear, support the car on stands and take off the wheel.
- Trace the lead from the hub carrier to its plug in the wheel arch area and disconnect it.
- Remove the single retaining bolt. Rear sensors on older cars corrode into the carrier, so soak the area with penetrating oil and twist the sensor gently to free it.
- If the old sensor breaks off, clean the remains out of the bore completely before fitting the new one.
- Wipe a little copper or silicone grease on the body of the new sensor, not on its tip, to make the next removal easier.
- Bolt it in, route the lead through the original clips and reconnect the plug.
- Clear the fault memory and road test.
Wear gloves and eye protection under the car. Because this part belongs to the braking system, ask a qualified mechanic to do the work if you are not confident.
One Sensor or Both?
Only the failed sensor needs to be replaced for the lights to go out. That said, both rear sensors have had the same life, and on a car of this age the second one often follows. If you are already paying for diagnosis and labour, changing the pair saves a repeat visit. This listing is for one sensor, so order two if you want to do both sides.
Who This Sensor Is For
It is aimed at E46 owners keeping an older BMW on the road, independent garages, and enthusiasts who are comfortable matching parts by number.
Common Questions
Is this a genuine BMW part? No. It is an unbranded aftermarket sensor sold under the BMW reference number 34526752683.
Does it fit the front wheels? No. The supplier lists it for the rear axle.
Will the warning light go out by itself? Often it does after a short drive, but on many cars the stored fault has to be cleared with a scan tool.
