  1. 05 1.8t No Start MAF or MAP or ????

    B5 Garage
    After a very long day of replacing my washer reservoir, my 05 started bucking about a mile from home and then died. No CEL and no restart. Had it towed home. Checked fuel pressure - was ok. Having done the bad MAF dance before, I pulled the connector to the MAF and it started right up in...
  2. MAF Mass Air Flow sensor wire test

    Volkswagen Passat B5 Discussion
    My 2003 VW Passat 1.8T automatic is in limp mode so I've checked codes and it shows a P0102. I ran data on the MAF with code reader but it didn't register anything on code reader. I had issues with a bad relay so no power to MAF at one time so I want to rule out lack of current at wire harness...

  4. Maf graph spikes at idle

    New Member Introductions
    Bought a 2004 b5.5 Passat 1.9tdi recently and have been having some trouble with the car going in to limp mode. Scanned it with a torque obd2 scanner and discovered that the maf graph spikes like crazy even at idle. This led me to replace the maf sensor, but this has still not solved the issue...

    Vag-Com and OBD11 Coding
    Been throwing a p0102 code for maf. Got my cable in and downloaded vcds lite and got it running. First time I have used this program. Was easy to get setup. Plugged it in read the code and logged a reading of 3.3 on the maf that didn't change with the rpm change. From what I've read it should...
  7. V6: false air to intake, bypassing MAF sensor

    B5 Garage
    I discovered today a loose worm clamp on my rubber pipe connecting intake manifold with the air filter housing. Not only clamp was loose but the rubber slip of the air filter housing and there was visible gap letting the air in, bypassing the air flow sensor... What symptoms would you expect...

    Volkswagen Passat B5 Discussion
    Hello everyone, Can someone help me find the right MAF for my '99 Passat V6 2.8L AHA (99.9% confident it's AHA engine)? I have tried multiple sources and I believe that the part number is 078133471C. However, I cannot decide whether I want to go with VDO (Siemens) or Hitachi. Bosch does not...
  9. MAF sensor causes engine to cut out for split second otherwise runs fine

    Volkswagen Passat B5 Discussion
    I am not asking for help or advice. I am posting this as a solution that worked for me in case anybody else has the same problem. My car was running fine except intermittently the engine would stop for a split second and then start again and continue as if nothing had happened. It shocked me...

    New Member Introductions
    HI so long time stalker, first time poster. I'm looking at buying a 98-99 VW Passat or Audi A4 with the 1.8T AEB motor and I've read a lot about how you can run K04 or Big Turbo on the stock ECU with a tune and add larger injectors/Adjustable Fuel pressure Regulator (along with FMIC/Exhaust...
  12. Looks like my MAF is shot. May I just disconnect it? (for a while)

    Volkswagen Passat B5 Discussion
    Yo there. Yesterday I was getting back from the grocery when my IDLE became pretty rough. The engine didn't stall but it was amazing how nuts the RPM gauge on the cluster performed. I pulled over for a moment and when I tried to get back to the street the car was completely out for power. As...

    B6 Garage
    Hi Folks, Just thought I'd throw this out there, my 2009 Passat wagon B6 2.0T is throwing a MAF code and appears to have zero turbo boost. So first of all, does that even make sense? I tried cleaning it with denatured alcohol and then again with electronics cleaner per suggestions elsewhere...
  16. MAF Wires damaged. How do I change them?

    Volkswagen Passat B5 Discussion
    I had taken out the MAF over the weekend to clean it. Apparently, I haven't been very careful with the wiring and they are damaged. Have had several issues in the past couple of days and now I am convinced they were all related to the damaged MAF wires. Today I cranked the engine and went on to...
