    One question, when I was looking at the coding for the ECU today, when you go into "coding", there's a pop-up balloon with coding info in it ... and it says something to the effect of (should have taken a screen shot of it) ...

    0000x?x
    +1 = ABS Brakes
    +2 = Airbags
    +3 = Climate Control

    0000xx?
    4 = Manual Transmission
    5 = Automatic Transmission

    The above may be inaccurate, but you get the idea ... what does this mean? If it's accurate, then my ECU is coded wrong.

    And concerning the EPB ... what if you were to leave it fully connected to power, but disconnect it from the CANbus altogether ... then disable it (in ABS and the CANbus, and anywhere else?).

    It would simply be a 12V electrical device in the car that was fully functional, but not "seen" by the electrical system.

    Although obviously, Auto-Hold would not work.

    Using that example your ECU coding would be 0000065 if you have ABS, airbags, climate control and an Auto transmission.

    The EPB is a fickle controller. Unless it is properly coded and connected it will not function, just throw faults.
    There may well be some way of getting it to work but it's well beyond my meager levels of expertise unfortunately...

    Interesting, here's a 2013 VW Passat 2.5L listed under "Reference Scans and Maps" ... it has no EPB! So maybe they simply don't pair up the 2.5 engine with the EPB for some reason ...

    Yeah the NMS is not a B7 Passat....at least not in the RoW sense.
    Its some sort of mutant mashup of a Passat and a Jetta.
    So I don't know what the best path towards a working car for you is...is it easier to lose the EPB and install a manual park brake, is there some way to integrate an EPB into a NMS, is it all a bridge too far?

    Thanks for all your help, I guess I'll just have to do more research on the ABS.

    Yesterday, I eliminated the "Trunk Elec." fault. Apparently, it was looking for an electric trunk release (I've got a wagon) ... or something. I unchecked it in the CANbus coding (I think), and the fault went away. I really do have to remember to document exactly what changes I'm making.

    I've still got a Brake Light Sw. fault and a Secondary Air Injection Relay fault that I've got to figure out (wiring issues). The Jetta uses a 4-terminal brake light switch ... the Passat uses a 3-terminal. That's probably why the Cruise Control will turn on, but it won't "set". The SAI works fine, so I may have wired it in a way that the Passat system doesn't "see".

    Other than those two things, and the ABS issue (some or all of which may be causing the EPC light and EPB lights to come on) ... everything else seems to work fine. The EPB works fine, it gives me a fault simply because it can't "talk" with the ABS unit. If I can eliminate that line of communication, then maybe I can eliminate the Parking Brake fault ... and pave the way for a Jetta or newer Passat ABS pump.

    I'll let you know what the outcome is, or if I have any other questions.

    Here's my last scan from yesterday (I recoded the ABS controller with the original Passat coding, then disabled ABS) ...

    I forgot to ask, is there any way to program the correct Passat VIN number into the ECU? Any dangers or side-effects of doing so?

    Today I fixed the Secondary Air Injection Pump Relay problem.

    Apparently, there are several electrical components on these cars that must be run through the J271 relay ... because the car continues to do functions and calculations ... even up to 15 minutes AFTER the car is turned off, and the J271 relay powers them to do that! The Secondary Air Injection Pump Relay is one of those components.

    I had it wired into a fuse that turns off with the ignition ... so hence, I got the following error code ...

    005173 - Secondary Air Pump Relay (J299)
    P1435 - 002 - Short to Ground - Intermittent
    Freeze Frame:
    Fault Status: 00100010
    Fault Priority: 0
    Fault Frequency: 8
    Reset counter: 255
    Mileage: 219399 km
    Time Indication: 0

    Freeze Frame:
    RPM: 281 /min
    Load: 72.5 %
    Speed: 0.0 km/h
    Temperature: 88.0C
    Temperature: 44.0C
    Absolute Pres.: 970.0 mbar
    Voltage: 11.303 V

    I rewired it into an unused fuse that feeds off of Relay J271 and ... the code is gone! Now I've just got the brake light switch and the ABS pump to deal with.

    By the end of this week I hope to take the car into the VW dealer, to see if I qualify for the 12-year rust through warranty.

    After much research, yesterday I ordered a used 2008 VW Jetta ABS pump with control module (1K0 907 379 AC), mounting bracket, and plug end from eBay .... $85 including shipping.

    After looking at the ABS wiring diagrams for both the 2008 Jetta and my 2007 Passat ... it looks like it will work. There are many VCDS scans on the internet using both my ECU and this ABS unit ... so coding between the two shouldn't be a problem. The above ABS unit also has ESP, so I should be able to retain that. The only downside is ... it doesn't have provisions for the Electric Parking Brake ... so I'll loose the Auto-Hold feature.

    I'll have to rewire the Passat ABS plug since the Passat and Jetta ABS units use different plugs ... and of course, the wiring is slightly different. It won't be such a daunting task as the ECU was since there are only about 16 wires.

    We'll see if this works! If it does, then that's the final frontier for this project!

    I'll deal with the brake light switch fault after I get the ABS installed and working ... the fault may be at least partially because of the ABS problem ... we'll see.
