BMS VW GTI JB4 info thread

You need to slit the rubber grommet under the brake booster.

Ive removed trim around centre console and can just feed it straight through to other side. Is the rubber grommet piercing necessary (cant really see it) or should i be ok to just push the cable through?

You're RHD so I don't know for sure, but on US models there's no straight path from the engine bay to the cockpit without goiing through a grommet.

The grommet is there, just to the right of where the wiring loom meets the bulkhead. Pull the black foam out of the way and you’ll see a rubber cone. Poke it through with a screw driver and feed a long cable tie through with the obd cable taped to the end.

Hey, does anyone know if the wireless connect kit can be used with an early model JB1?

This worked! Thanks. Took a while mind you but got there in the end

If it is a unpinned version where you connect the blue power wire to the red wire in the JB harness it will work. On JB1 it can only change settings, maps and display boost and rpm.

So I got the o2 sensor code. Now I do have a downpipe...but the reason I'm asking here is because it started happening with the JB4. I ran the DP with the Neuspeed module for about 900 miles with no CEL. The JB4 went for about 200 miles...then the CEL came on. I cleared it...then within about 70 ish miles...the CEL came back. The DP I have is a Wagner Tuning. The cat is in the stock location...and so is the bung for the o2 sensor. Is this something related to the JB4?

I wanted to add that coincidentally...it came on after the intercooler install.

Bank 1 is the first o2...the one with the black sleeve? That's the wire I tapped for the AFR wire.

I just got a 66A7 error code after some canyon driving. Anyone know what it means?

I just installed my JB4 and can't get the data logging to work. I'm using the data cable, it connects to my laptop just fine. I am able to view the data in real time in the boxes below the graph, and I am able to change maps. It seems everything is working, but when I try to log nothing happens. In the top of the window it says something like "starting logging", but nothing happens. Am I missing a step?

Thankss

MAP sensor fault. Have you done anything to that area lately?

It was the "nail it" part I was missing. Looks like the software defaults to logging only at WOT, I was just testing it out when I was revving the engine at idle, so nothing was recording. It worked once I un-checked that option.
