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,

  • 1995 T4 transporter 2 ltr petrol fluctuating revs ?

    Have what could be the start of a problem. Occasionally (50% time) when revs come back to idle the revs drop to almost stall, about 200 rpm then settles back fine, likewise if I hold accelerator at about 1000 to 1200 revs the revs keeping dropping and rising by about 300 rpm. Any ideas of where I should look. Thanks

    a wild stab in the dark..
    have you checked air mass meter/air flow meter, and possibly any vacum lines, tho I'm not to familiar with the petrol engine, might run a different middle control set up as the diesel unit.

      As above, check AFM and vacuum lines. Other possibility is the O2 sensor/s if the 2ltr has them???
      Had my AFM disconnected for a while without realising and had similar idle issues...
