I am at my wit's end with this. This is New Beetle #5 for me. It is an 07 Triple White convertible with the 09G transmission. I got it for relatively short money, with some issues. Needed a battery and alternator, and throwing codes 00268 for the N93 solenoid and 01045 for the Tiptronic switch. Put in a new battery and an aftermarket alternator. Also picked up a used Tiptronic board for the shifter, and that took care of the 01045. No, it wasn't the magnets. Now for the 00268, which I can clear but keeps coming back. I put in 2 different aftermarket solenoids. Code comes back. I tried 2 TCMTCUs (same exact moded), code comes back. I checked and cleaned every ground. I check all of the wiring. Everything checks out as it should. Back to alternator for a moment. So I noticed that after I installed the new alternator, the battery would drain after a few days. If i used a screwdriver as a stethoscope and touch the alternator, i can hear the alternator humming with the car off. It's drawing about .4 amps with the care off. So I have sent out my original alternator to be rebuilt at a local trusted shop.
I have seen at least one or two posts with the same issue (battery draining and 00268), but no solution posted! Any thoughts at all out there? I would gladly throw in a rebuilt throttle body from Reamann if I thought that would fix it. I do not have VAG COM (I've been able to get by without it through 4 other Beetle on which I have done tons of work, as this forum has always had the answer). Do you think it might be the ECM/ECU?
I do have ODBeleven. Here's the outoput.
Fault code: 00268 (268)
Measurements: 1.2 v.OT
Frequency Counter: 3
Mileage 226477 km
Driving cycle: 0
Any help at all would be appreciated. Thanks!
