Hi new beetle team,
I bought last month ago a 2000 VW 2.0L beetle, before I bought it the first owner told me that nobody was able to start the car and was already 9 years that it was staying in the owners garage. They was unable the determine why the car doesn't turn on, so I bought it and took it to my home, I bought a brand new battery, put it in, the lights doesn't even come on, so I started to check wires, after 2 days running every cable I found in a lot of dirt, chicken bones and a lot of old mango's in the car at the top of the dash, the rats eat most of the cables, so I start repair every cable, after that the car started, I changed the spark plugs, ignition coil, spark plug wires, clean the fuel tank, changed the fuel filter, change the fuel pump, bought new camshaft positioning sensor, replace the o2 oxygen sensor, clean the injectors, changed the maf sensor, timing belt, water pump, timing belt, everything, but I still having problems, my vag com computer is giving me code p0300, p0304, and the car doesn't idle good, it's like losing electricity power, it comes and goes back, and the check engine comes when the car is cold, do you guys know if there some sensors or something that is causing this? Or a wire that could be damaged in the car? In the engine compartment every cable was ok...

Cylinder 4 Misfire Detected: so, you could check that cylinder specifically.

Lots of possibilities; read the above links, to start doing some testing and a process of elimination. You have just about; replaced everything that controls the engine! Did you use; high quality parts for: maf, wires, coil, spark plugs, sensors etc. poor quality parts, can cause even more problems and complicate, you troubleshooting process!

A "hard" reset; can never hurt, remove positive and negative battery cables, touch together for 30 seconds and re-install.

One thing; that I noticed, you didn't do... was clean the throttle body and realign/adapt using VDCS. Maybe, after all these years; it might need to be realigned? Worth a shot; people have mentioned fixing poor idle issues by doing this! Aside from that; it seems to me, #4 cylinder misfire is your primary issue, you need to figure out.

What scanner; are you using (hand held, VCDS lite, full etc.)?


Using VCDS: choose: control module: engine: measuring blocks: channel 019? Should show misfire counter and show which cylinder is the problem. This would be in real time (engine running); so, it would confirm #4 and eliminate other possible misfires. Other channels; show more info, just click on the button and click the "up arrow" to see more info, on other channels.

Thanks billy, I wake this morning and clean the throttle body like you said, no succes, after 3 hours of troubleshooting, I decided to take the car and drive it for 1 hour, at 120 km, after that went to the garage back, and boem, no misfire, no check engine, it start working like new, I don't don't know what clean, or what was dirty, I took it on high way and start racing, I think all the dirt came out.

One question, someone here knows why the left door doesn't open with the fob key?
I replaced the door accurator and window motor, it doesn't open the door, even if you try to open it using the buttons at the door, only the passenger door opens, with the fob, when you press the fob 1 time, the lights outside the car flicks, but the driver door doesn't open, if you press it twice, the passenger door opens correctly, any suggestions?

Wow! Very cool; on the throttle body cleaning; every time I have done this cleaning/adaptation, I can't believe the difference it makes! Many have said; the 2.0L TB can get really dirty and will kill power of the engine. I'm so glad; things seem much better! :D

On the door unlock issue; are you saying you replaced the door control module or just the actuator? I wonder; if that dcm, needs to be adapted to the ecm?

I would start testing; for power at the switches, unlocking actuator/switch, it maybe the wiring has problems (many people; have had wiring insulation/wires break near the hinges). Any codes with VCDS; there are probably output tests for the actuator. You might try removing switches on the "good" side and vice/versa ; to confirm that they are good/bad.

By the way; "chicken/mangos", makes me wonder where you live! Why not start a threat; showing off your new beetle and some info, about where you are from? It would be nice; if you wold fill in your year/model of your beetle and location. :)
