    Thread: My 2003 New Beetle Convertible 1.8L Turbo won't start!!

    1. 07-04-2020 03:15 AM #1
      My 2003 New Beetle 1.8L Turbo turns over but never starts. In the past few months it occasionally took 2 or 3 times but in the end it always started. This time it won't start at all.
      So far I have replaced the speed sensor with 2 known good ones but that didn't help.
      The only thing out of the ordinary I noticed was that it idled high (1200 rpm) after start up. Once warm that went back down..

      The following is my latest scan:

      Unsure what to tackle first because if it doesn't start it is hard to test or fix some of the fault codes.
      So I am trying to figure out which one is most likely the reason it won't start.
      Any ideas?

      Got it started for a minute by unplugging the mass air flow sensor. But now the EPC light on dash came on. Can I drive it like that?

      You have a ton of codes and your immobilizer, has been kicking on, which will cause a no start condition. Have you had any issues with low battery or charging problems? This can cause havoc with these cars and throw, all sorts of random codes and kick the immo on, which will cause the immo light in the dash to flash, the car will start for a moment and then, die. You might try a hard reset of the ecu; clear all codes and see, what comes back. If you have had charging/voltage issues; I would have that checked out and repair/replace, anything that is not working as it should. Report back, any codes; that come up (again), then you can work through each one and try to resolve those problems and we can go from there, thanks.

      My battery was stolen so I had to replace it but no low battery voltage. Like I said, unplugging the mass airflow sensor got the car started so I am definitely replacing that. Unfortunately the wrecking yard close by has closed down until further notice so I have no idea when I'll be able to get that.
      And now that I was able to drive around for a bit I will re-scan and get back to you with the results.

      see what your mass air flow reading is using the live readings feature on vcds. I recently had a MAF problem, but it was a blown fuse for the fuel pump relay.

      Many times a low voltage/charge issue; will goof up the immobilizer, which will kick on and kill the ignition. After the install of the new battery; you might run down to a local auto parts store and have them, do a full charging system test and confirm, everything is working as it should. You might do a hard reset of the ecu: remove the positive and negative terminals on the battery, touch them together for a moment, then reinstall. This can clear the ecu and many times, can solve goofy immo issues. Then, test drive the car and do a full autoscan, see if any trouble codes come back, report what you find, we can go from there, thanks!

      Haven't had the chance to drive the car anywhere because they have rolled back all the covid re-openings here in San Francisco.
      I did drive the car today finally so I am running another scan this evening and I'll get back with the results tomorrow.

      Today the car wouldn't start again. I tried unplugging the mass airflow sensor but that didn't help either this time.
      I ran the scan anyway. This is what I got:

      After that I cleared the codes for the engine. Tried to start the car but nothing.
      Checked the engine codes again but they were still clear.
      Where to go from here?

      You have allot of codes; this code, could be a clue to the no start issue?

      http://wiki.ross-tech.com/wiki/index...5/P0321/000801

      Basics should be checked: ignition spark, fuel pressure, compression, etc.

      I have already replaced the speed sensor twice but after a while that code keeps coming back.
      Meanwhile I have unplugged the mass airflow sensor. It now starts again but it sounds unhappy at idle but when I drive it it sounds fine.

      Actual testing, will be required; to find the problem.

      The basics, need to be checked; if no start: is there ignition spark, fuel pressure, compression?

      You have a wide range of trouble codes; for example, the crank/engine speed sensor, code is still being thrown. So, in that case, is there ignition spark? If not then, testing and troubleshooting is needed.
