febi bilstein 37606 Parking Brake Switch (pack of one) – black plastic replacement
Product description
The essentials
The febi bilstein 37606 parking brake switch (pack of one) is a straightforward replacement part for your car’s parking brake system. As the name suggests, it’s a switch unit intended to replicate the “original spare part” style fit, so the goal is simple: get the switch function back where it belongs.
On paper, it’s the kind of part you buy when the current switch is causing warnings, inconsistent behaviour, or simply stops doing its job. It’s not a high-tech add-on or a performance upgrade—more of a practical fix aimed at restoring normal operation.
What it’s for, and what you’ll notice in use
A parking brake switch is part of the logic that helps the vehicle recognise the parking brake state. When that recognition is wrong, you can end up with annoying dashboard indications or behaviour that makes you double-check whether the car is actually secured.

With this switch, the main promise is that it’s designed to be a like-for-like replacement, using black plastic and a key activation type. In day-to-day terms, that typically means you’re looking to return the system to consistent operation rather than chasing anything fancy.
A small, human example: say you finish parking, pull the parking brake as normal, and the warning light doesn’t behave as expected. Replacing the faulty switch is exactly the kind of job that often clears up that “why is it still showing?” hassle—assuming the original issue is indeed with the switch.
Key features that matter for fit
febi bilstein positions this as an original spare part solution, and it comes with a set of details that help you judge whether it’s the right one before you order:


- 8 connections (so it’s not just any generic switch)
- Black plastic body
- Key activation type
- Low stated weight for a small switch component

You also get OE reference numbers listed for cross-checking purposes. The entry includes VW reference 3C0 927 225 C (for comparison purposes only). That’s useful when you’re matching parts by number rather than relying purely on description.
Where it fits (and where it may not)
The listing is explicit that compatibility must be confirmed using vehicle identification details. It also notes that all restrictions must be observed. In other words, don’t assume fit purely from “it’s for a parking brake switch”—this is one of those parts where the exact car application really matters.
It’s described as suitable for certain VW models, including:
- Passat 5 (3C)
- Passat 5 4motion (3C)
- Passat CC (35)
- Passat CC 4motion (35)

It might not be a great match if your car’s parking brake switch specification differs from the connection count or activation type. If you’re missing the correct reference for your vehicle, you may end up with the right-looking part that still doesn’t fit properly.
Warranty and installation reality check
The entry states a 12 month / 12,000 mile warranty. That’s reasonable for a small electronic/actuator-style replacement in this category.


It also flags that specialist fitting equipment may be required. That’s worth taking seriously: some vehicle switch replacements are “simple” only if you already have the right tools and access. If you’re going DIY, make sure you’re comfortable with the process and don’t count on it being a five-minute job. If you’re booking a garage, having the correct vehicle identification confirmed up front can save time.
What to verify before buying

If you want to avoid returns or delays, the practical checklist is:
- Confirm compatibility using the vehicle identification at the top of the page (as the listing instructs)
- Cross-check the OE number (VW 3C0 927 225 C is provided for comparison)
- Make sure the connection count (8) and activation type (key activation) align with your current component
If those points don’t match, it’s not the sort of item you “might make work”. Better to check properly first.
Is it worth it?
This febi bilstein 37606 parking brake switch is a sensible buy if you’re chasing a specific parking brake switch fault on a compatible VW application, and you’re happy to use the vehicle identification and OE reference to confirm the match. For many owners, that’s the best way to get back to normal behaviour without paying for guesswork.

It’s not the best choice if you can’t confidently confirm compatibility, because parking brake switches can vary in connection layout and activation style. And if you were hoping for a universal, plug-and-play replacement, this is more “correct part for the job” than “generic fix”.
