*** This post is still in work, but will be complete in the next few days ***
Electronic Parking Brake Retrofit is done! (physically anyway, need to code everything, I consider that minor)
Edit: Coding is now done as well, everything works, including Autohold... with green (P) indication if you have a ROW cluster... shout out to @Kushdaiin
So I guess I'll try to make this into a semi-informative post now that I've done it...
The
prices are MSRP from VW unless otherwise stated but generally found at some sort of discount, and sourced from various vendors
- I often order from VenturaVW here "in" LA because they offer the most discount, they will then source the parts from the dealer that's actually closest to me that seems to have a large warehouse but offers very little discount
.
Rear EPB Calipers/Carriers
Left Caliper:
5Q0 615 405 CT (this is a part number for caliper and EPB motor, VW doesn't sell it but eBay does)
- You could buy left caliper
8V0 615 423 E $410 and left EPB motor
3Q0 998 281 $683
Right Caliper:
5Q0 615 406 CT (this is a part number for caliper and EPB motor, VW doesn't sell it but eBay does)
- You could buy right caliper
8V0 615 424 E $390 and right EPB motor
3Q0 998 281 A $521
Left and Right Carriers:
8V0 615 425 B $205/each
Sourcing these was kind of a pain, but I ended up buying a full set of Golf R brakes on eBay, then selling the fronts in the classifieds. People don't do much more than replace pads/rotors for the rear. I couldn't get any of the eBay folks to sell me just the rears. If you're willing to wait then getting these on eBay international is probably the way to go. Only the Golf R (and I suppose S3) got the EPB brake here in the states but ROW the GTI got EPB also (along with the Audis). The used part market across the way is better in general.
Assuming you source the above parts used...
- I opened up the EPB motors to clean/inspect/grease... EPB motor seal kit -
5Q0 698 365 or
8V0 611 243 $6/each
- Also popped the pistons out just to make sure all looked okay... piston seal kit -
8V0 698 671 A $24/each... or Centric PN
143.34021 $7/each
- Caliper Pin Kit, might as well right -
8V0 698 647 $34
EPB Motor Connectors/Plugs
EPB motor plug (2x) -
6X0 973 722 G $35/each
- On the Golf R this is an integrated harness with abs sensors, which your car will already have
EPB motor plug boot/dust seal (2x) -
1J0 906 102 $6/each
EPB motor plug repair wire (2x, so 4 pins) -
000 979 133 E $15/each
- Back of the connector where the wires enter should be sealed. I used a bit of RTV.
- If you're patient and/or smart you may be able to save some money by getting pre-built sealed pigtails
from here. I have not ordered from them (yet) but they have pretty much every wire/connector/pin I've ever mentioned and for good prices. They are in the UK so shipping will make ordering from there not worth it unless you're buying lots of stuff.
ABS Module
If your car came with 38 pin ABS (probably a 5Q0 part number) you will need to replace with a 46 pin ABS (3Q0 part)
- Part called out for the Mk7 Golf R by VW is
3Q0 614 517 AF (previously 3Q0 614 517 AA) $1655
- I went with a used Golf R module, part number 3Q0 907 379 AA for under $100
The ABS "unit" is 2 parts... the 3Q0 614 517 xx part is the hydraulic pump, the 3Q0 907 379 xx part is the electronic module
- A 3Q0 614 517 AA (or AF) pump should be mated to module 3Q0 907 379 AA (or AF)... sellers typically list the module part number, just verify both in the pictures
46 Pin ABS Connector
4M0 998 046 $50, or
8V0 998 623 $11 (I have no idea why the Audi PN is so much cheaper
)
46 Pin ABS has an extra ground, you need to splice to one of the 38 pin large grounds, repair wire
000 979 308 E $34
EPB motor pins, medium size, need 2 for each motor, repair wire
000 979 242 (4 pins, so 2 wires)
$41/each
You'll need some miscellaneous pins as well, small
000 979 046 E $9
- I recommend
@Nuje's
guide for replacing the ABS pump, it mentions the fun you'll have due to the DPF, but ignore that on a gasser
- I also recommend
@golfdave's addition of
ESC Control and
TPMS Set buttons (if you don't have them), a classic "while you're in there" job
- AliExpress sells an ABS pigtail fully loaded with wires, as PN 5Q0 973 046 for about $25
- Cheaper than repair wires, replace the wires in the pigtail with your existing ones as needed, use the new pigtail wires as needed
- In retrospect I would go this route for the connector/repair wires, save time (not really, Ali shipping is slow) and money
Electronic Parking Brake Switch/Button
EPB switch/button -
5G0 927 225 D $91
EPB switch/button plug -
8E0 972 112 $16
- I bought 2 pigtails on eBay, but I
think the repair wire is
000 979 009 E (11 pins, so 6 wires)
$20/each
- Note: I bought two pigtails and scavenged a few pins... cars that have an EPB module use the same switch/plug but have fewer wires. On our car the EPB "module" is integrated into the ABS Module. I suspect a few wires that used to go from EPB Module to ABS Module are now going straight from EPB switch to ABS Module.
- You need 11 pins wires so if you get a pigtail with 11 you're good... the pigtails I found in eBay had fewer, so I stole some from one to make a complete one. Still cheaper than buying the connector and repair wires.
Center console is getting it's own post, next...
