My 04 jetta will not go above 3000 RPM, any ideas?
i would check the MAF sensor, if it has a fault it goes into limp mode and runs on fixed parameters, most of the time that won't allow the car to go over 3000 rpm
make sure your not using the valet key too, the car doesnt go over 3k or 4k rpm's with the valet key
I know this probally isn't much help but I am having the same issue. Maybe you can save some money here, I have replaced the camshaft positioning sensor, spark plugs and wires and the problem was not solved.... Thinking the knock sensors next than the speed sensor.
I had a similar problem a few years ago with misfiring cylinders
crank position sensor
now i had posted about the cam sensor and after alot of wasted money it turns out that I had purchased a defective cam sensor...... when i scanned the computer the camshaft sensor code displayed...... changed the sensor and the car is as good as new.. this was on the 2.0 vw engine
