EPB Switch - Which One To Buy?

[Deep Blue]

After a scan with Foxwell scanner and a detailed read through this forum and others I reckon I need to swap out the EPB switch (2009 Passat CC 2.0L TDI) as an obvious and cheap first step. Prices for EPB switch part#: 3C0927225C as follows:


Melbourne dealer - $117.70 pick-up from dealership; incidentally the dealer uses part#: VW-3C0927225CREH

Melbourne based eBay seller (and VW mechanic) - $27 delivered (described as "...quality aftermarket...")

Aliexpress.com - USD 2.99 (many sellers, but most charging less than USD 8.00 delivered - standard delivery though is 4 - 6 weeks); aliexpress seller uses two alternative part #s: 3C0927225C or 3C0927225B

Any thoughts or experiences to share?

Given the price, might just buy one from aliexpress (from buyer who has more sales)?

Any suggestions or things to watch out for?

Get the genuine one. It's the latest version, and not considered problematic.

The genuine one then is the one with the "...CREH" at the end of the part number? I assume then this is the one available ONLY from the VW dealers for c. $117?

Okay, after a considerable forums search, internet sellers search, and a good deal of consideration, I purchased a Topran brand switch from runautoparts.com.au - AUD 32.95 delivered. Didn't realise so many companies made/supplied (to VW)/sold these switches! Anyway, Topran it is!

EPB switch arrives tomorrow, so guess it's as simple as:

1. Remove old switch and install new switch - looks pretty easy

2. Disconnect battery for 10 minutes and then touch both leads together to drain any residual charge to earth (?)

3. Reconnect battery leads to battery

4. Clear any induced faults (battery disconnected) with scanner

5. Test park brake switch and park brake


Is that correct? Did I miss anything?

You could probably get away with just swapping out the switch, no battery jiggery or pokery.

I'm now thinking of fitting a Polariser.

Okay, installed new Topran EPB switch. Didn't disconnect battery or anything, just removed switch (needs a bit of a tug to release plug from back of switch once popped out from dash). Popped new switch in, started car, pressed a couple of times - all good it seems (you can hear rear PB motor engage/disengage as switch is pressed). See how we go over next week or two...

Now, next one is flashing amber tyre pressure warning light, even though tyre pressures are spot on! Is this a faulty ABS sensor?

Okay, parking brake working perfectly and no warning light - all good, no recurrence so it looks like the AUD 32.95 Topran EPB switch (delivered) did the trick. That one was "simples"! Great to have a forum like this!

Flat battery in sensor probably

Just wanted to mention, I had the same problem and tried an ebay cheapie switch ($6)
Didn't work. Has the part number 3C0927225C but eventually gives an error.
The fake switch has noticeably more play in the sliding mechanism than the genuine one.

Topran switch (German) looked 100% like original and is a perfect fit. Was all good for some time but now need to check the driver's side EPB motor (other thread).

[minorityracer]

I've ordered the Topran switch. I'll let you know how it goes.

Yeah, bought electric window door control panel from aliexpress several years ago to replace the original. It was a cheapie but when I received it I was very impressed! Has worked like a charm for several years now. With the EPB switch, after a fair bit of research I settled on the Topran from RunAutoParts.com.au.

Swapping tyres from front to back today and going to inspect the driver's side (rear) EPB motor - have been getting a fault on the dash. Might have to buy a new EPB - will go with aliexpress on this one given the dealer price is around 20x higher!!!

When I get new tyres I'm going to look out for new TPMS modules.

I installed the Topran EPB switch yesterday. It works really well. I’m very happy. No further faults.

With the original and also the AliExpress switch I was getting both switch and module faults.

I ordered a spare AliExpress EPB motor a few weeks ago, just in case I need it. Hasn’t arrived yet.
