Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before. We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

  • Need to run some wires through the firewall

    Need to run some wires through the firewall. What's the best way to do it? I want the wires to end up at the fuse box under the glove compartment

    If you pull some of the carpet back up near where it meets the glovebox, there's a rubber grommet which can be pierced to accommodate wiring. This is how the OBD2 wire for a JB4 is typically routed.

    It's a bugger to get to though, and you will ideally need to create a small slit in the grommet to pass the wiring through. A metal coathanger or similar stiff wire is useful to help draw/push the wire through the hole.

    The wiring will pop out behind the battery. It can be fiddly to reach - two people (one wiggling from inside the cabin and one waiting with a torch from the engine bay side) makes the job easier.

      Even better... a walk-through with pics! This applies to the Passat too.

          Just to note on my rline Passat, which has the battery in the boot, I found it impossible to add sealant on the engine side of the firewall as it is very hard to get you hand in where the cable comes through.
