      Alright here this is my second time posting for the same car and same issue but now it has intensified! The car will just die for no apparent reason and decides it does not want to start again until...it decides to. It does not matter whether its hot or cold. You could drive it all day or you wont even make it out of the driveway.It has many and I say many new parts and 130,xxx on the clock. When it is running, it runs mint. There is no real rhythm to its chaos. I have checked and rechecked, tune-up, new coils (less than 3,xxx miles ago), new starter and battery. I am at wits end and don't know what to think!?! or where to start

      sounds like it could be a faulty ECM relay. the relay is located is position 3 of the fuse/relay panel. the fuse/relay panel is under the dash on the drivers side. iirc those relays are known for failing. i would order a new relay but wait for the problem to occur again with the old relay. when it does swap the relays, this will tell you if you actually fixed the problem. if it doesnt, the relay is cheap and its never a bad thing to have a spare

      Worth a shot, I had the same issue and replaced the ECU relay (357 906 381 A);
      however, IIRC it is for OBD1 only - yet OP has a 1995 B4, which may or may not be OBD1.
      Double-check the ECU # to confirm.

      With all of this happening with no real reason....when it does die, like I said it won't start unless it wants to. It will turn over beautifully and like it should but, it seems as if it is not getting fuel. With that you can here the fuel pump kick on but still no start. When it dies you may be lucky enough to restart it right away and if not it takes atleast 20 minutes or so if not longer. The problem has been getting worse, before it would pop off right away. When it does restart (sometimes) it acts as if it is missing or struggling something fierce, than will clear up as if nothing happened. Also the check engine light will be on occasionally but only at start up. This will also turn off within minutes of driving. When the engine light is on, it feels sluggish and you can literally feel when it goes off and once again as if nothing were wrong. Fuel mileage is excellent, pick up is there and doesn't smell rich or too lean.

      again, it really sounds to me like the ECM relay. often times as a relay gets worse the problem will start happening more frequently. its cheap, easy to install and if you dont wanna wait for shipping most dealers should have it in stock since they used the same relay in the mk4's. i believe it lists for around $30 at the dealer, p/n for the updated relay is 1J0 906 381A

      Alright...got enough nerve to take it out regardless the chance of being stranded. It did not kill but, it ran mint than it seems to miss or as I say like lawnmower. This happened all through out the test drive. Now it keeps doing it without dying. But runs as if someone switches a switch onto pile mode.

      Back again....now my problem is taking turns to where ever it wants to go. The stalling part of the problem seems to no longer be there. It will switch over to lawn mower mode (as I call it) after it is warm and it will go back and fourth from running kick ass to barely running at all, occasionally it may stall but it will fire right back up sounding like a performance mower.
      What I have done since this problem,
      1. Battery and starter (went weak and needed replacing after several no start situations)
      2. Replaced all relays (except the 109 ECU relay)
      My BIG question about this relay is...Some say it wont start and run if this relay is bad, correct or incorrect?
      3. Checked starter signal wire from ignition to starter
      4. Checked fuel pump operation
      5. Checked other fuel related possibilities
      6. Replaced the "Blue" coolant sensor
      7. Replaced Spark plugs
      8. New coil
      Symptoms:
      Car will run and drive fine for roughly a half hour or so, than it will just start to sputter and miss. You really have to ride it right in hopes of not being stuck in a bad situation. If you shut it down it may start or not, everything seem to be working properly (starter, fuel pump). The car will not fire up but turns over as if it has no fuel or spark. If this happens it will take up to 10-30 minutes to restart and than the problem will be gone...if your lucky.
      PLEASE HELP! This is my daily driver, I have never given up on a Dub and do not plan on starting with this one.

      Check the crank position sensor, aka ESS. I get intermittent problems where my car won't start aswell, and I have had the Implausible CPS signal code before.

      Well since my last post and many responded throughout the week...I replaced the 109 relay today and thought it was fixed of all problems. Test drove and was not to easy on her and wouldn't you know it......nothing runs like a deer all over again. Kept my foot in her til I got home and pulled into the under ground parking and boy did she smell hot! To a peek underneath and wouldn't ya know it looked as if I had some neon lights that matched my neighbors ugly Honda. Well guess this is onto installing the exhaust I had already ordered upon purchasing this B4.

      It is missing on 3-4...only when it gets warm. Problem persists until you leave it to completely cool down
      . Had the car on a short test drive and no problems, came home and let her idle and to let the temp come up. The temp came to operating temp 2-3 different times with the fans doing their cycle. After roughly 20 minutes into all of this, it was as if someone pulled the wires and it began to mis again. I did notice when replacing all the relays that is missing the A/C and #43 low coolant relay, will these make any sort of difference? I am hesitant on purchasing these after dumping a load on 12 relays already.
