Frequently Asked Questions: OE 13940874-00
Will this parking brake motor fit my car?
This EPB motor carries the OE number 13940874-00, though a model name on its own is not enough to confirm a match for your specific car. Compare the number stamped on the motor you are removing with the entries in the fitment table on this page, which sets out the exact vehicles and years this part covers. If the two do not match, do not fit it, since an incorrect motor will not work correctly in the parking brake system.
What if the number on my old motor does not match?
If the number stamped on your old motor does not read 13940874-00, do not assume straight away that it is the wrong part, since this motor is also listed under a second reference. Look closely at the photographs on this page and compare the shape and connector against the unit currently fitted to your car. A visual check against the photographs is a safer way to confirm the match before you order and remove anything further.
Can I fit this EPB motor myself or does it need a professional?
This sits within the braking system, so fitting is not something to guess at. Before you do anything, check the old part against OE number 13940874-00. This assembly is also listed under reference TA-3502310S, so if your old part or a workshop manual only shows that code, it still points to the same unit. Match either number against what is on the car, then use the fitment table on this page to confirm before ordering or booking it in.
What is this parking brake motor made of?
The housing is metal rather than plastic. Before you order, have the old part sitting in front of you so you can check its size and condition against this one, rather than relying on memory once you are back at the vehicle. A quick side by side look now is easier than discovering a mismatch after you have already started the job.
Where does this parking brake motor fit on the car?
Underbody is where this sits, working as part of the parking brake system rather than anywhere visible from inside the car. Because of that position, confirm exactly what your car needs before you commit to an order, rather than guessing from a general description. Use the quote route on this page and send a photograph of the old part and its label, so the fitting is checked against the OE number before anything is booked in.
