  1. B5.5 Bosch 5.7 ABS Login/Coding issues

    Volkswagen Passat B5 Discussion
    Thanks especially to the fellow forum members at Forums.ross-tech.com, the mystery has been solved and I have my ABS module correctly coded and functioning. The key issue was that I missed the asterisked T7F engine entry in line #5 for both the login and coding (which specifies that code if...

    Also - I tried an ABS controller out of an identically optioned wrecking yard car, but it does the exact same thing.

    Additional info: I contacted the prior owner (who was the 2nd owner and only owned it a few months but he had been given a huge box of receipts from the original owner who was meticulous about maintenance). He have never experienced a single fault with the car, but the dealer he traded it in to...

    I have a 2004 Passat 2.8L, auto trans, 4Motion wagon that I bought a few months ago at auction. At that time it had mutiple engine fault codes and would get the infamous beeps and flashing brake & ESP lights along with the following ABS fault codes: 00778 - Steering Angle Sensor (G85)...

    Passed emissions and it now has registration!!! To summarize: Several vacuum leaks in hard plastic lines under the hood (likely from the detailer pressure washing the engine compartment), then replacing the post-cat O2 sensors and adding spacers to them (which may not have been necessary but I...

    I ran errands in the car tonight, then ran through the "Set Readiness" sequence in VCDS. Success!!! Finally got this thing to show complete emissions readiness, so as long as it doesn't get a fault on the way to the inspection station I can finally license this thing! I don't want to touch a...

    My great plans didn't work so well due to UPS. I ordered the O2 sensor extenders and paid for next day shipping, but it took almost a week to get here thanks to UPS misrouting. After trying to get the same thing locally I decided to try drilling out some "spark plug anti foulers" (Dorman...
  9. Bosch 16073 O2 connector issue

    Volkswagen Passat B5 Discussion
    I just ran across this same problem this morning. Per the cryptic pictorial Ikea-like instructions with the 16073 replacement sensor, you need to swap the brown vehicle-side connector housing with the black one that comes in the package. OR if you are in a huge hurry like I was this morning...

    The breather hose fixed the prior fault codes, but now I am getting the following after running a "Set Readiness" step with VCDS: 16805 - Warm Up Catalyst; Bank 1 P0421 - 35-00 - Efficiency Below Threshold I drove it to work today to see if more drive time would remove that code...

    It's pretty crude but effective. Made from a new quart paint can, a heating element and wick, and a BBQ pressure regulator.

    My smoke test machine got delayed for several days by our local post office, but finally arrived yesterday. As soon as I hooked it up this morning it showed a leak from the hard plastic breather hose that runs to the passenger valve cover. I previously tried pressurizing the whole vacuum...
  15. New 2004 4Motion Passat owner, trying to fix ABS faults!

    New Member Introductions
    I still have not figured out this issue, but I have been focusing on trying to fix the emissions faults lately. When I tried coding the ABS controller it immediately quits communicating (showing a fault on the Engine controller for losing communication with the ABS controller), until power is...

    I am new to Passats but have been wrenching on my own 2000 Jetta TDI for 11 years. I have Vag-Com and a lot of the specialized tools if anyone needs a hand. I just bought a 126k mile 2004 Passat 2.8 4Motion wagon, will be doing a timing belt on it soon, and am now trying to chase down...

    I have a newly-purchased 2004 Passat V6 4Motion with ESP with 126k miles, and it has the following ABS system faults: 00778 - Steering Angle Sensor (G85) 66-10 - Not Matched - Intermittent 01044 - Control Module Incorrectly Coded 35-00 - - So I assume it needs the...

    Hi everyone! I have been a longtime VW owner (2000 Jetta TDI for the past 11 years) and do all of my own wrenching, so I am fairly well versed in Bentley manuals and VCDS/VagCom. I have a newly-purchased 2004 Passat V6 4Motion with ESP with 126k miles, and it has the following ABS system...
