Done lots of searching and reading on this and other forums and still wrestling with this issue.
Car is a 2006 Jetta TDI 5MT (MKV) with a bad battery drain issue. Started by charging and disconnecting the battery, will hold a charge for days disconnected from the car so the battery is fine. Then began with a VCDS scan that is showing only one pertinent DTC, 00470 Combination Comfort Databus in One Wire Mode. Measuring blocks show the CAN gateway will not go to sleep due to this assumed broken CAN wire somewhere. Following TSB 27_08_04 I checked the fuses and found fuse #15 for that module is pulling around 100mA after the door switch is fooled closed and the interior lights go out like normal. That one circuit is pulling way more than the >40mA the whole car should consume at rest. This makes sense considering the CAN gateway will no go to sleep.
Going with the most likely causes, the radio and driver door wiring harness, I first made note that neither had any DTCs set. Unplugging either will cause the CAN gateway to not see that controller (or radio) but will recognize them again as soon as plugged back in. Both are behaving normally and a physical inspection (as much as can be seen) of the harness to the driver door shows no damage to the wires in the normal breakage spot.
Before I post the VCDS Auto Scan results, I will ask if anyone can guide me on the next step for troubleshooting?

I found a TSB for the airbag DTC, looks like a high connectivity resistance under the passenger seat that the TSB is guiding the tech to wire around the questionable connector. I don't see that causing this. The DTC for the steering angle sensor is likely from having had the battery disconnected. A recalibration once the issue is resolved should take care of that - again, thinking that is not going to pertain to the battery drain either.
Thanks in advance!
Car is a 2006 Jetta TDI 5MT (MKV) with a bad battery drain issue. Started by charging and disconnecting the battery, will hold a charge for days disconnected from the car so the battery is fine. Then began with a VCDS scan that is showing only one pertinent DTC, 00470 Combination Comfort Databus in One Wire Mode. Measuring blocks show the CAN gateway will not go to sleep due to this assumed broken CAN wire somewhere. Following TSB 27_08_04 I checked the fuses and found fuse #15 for that module is pulling around 100mA after the door switch is fooled closed and the interior lights go out like normal. That one circuit is pulling way more than the >40mA the whole car should consume at rest. This makes sense considering the CAN gateway will no go to sleep.
Going with the most likely causes, the radio and driver door wiring harness, I first made note that neither had any DTCs set. Unplugging either will cause the CAN gateway to not see that controller (or radio) but will recognize them again as soon as plugged back in. Both are behaving normally and a physical inspection (as much as can be seen) of the harness to the driver door shows no damage to the wires in the normal breakage spot.
Before I post the VCDS Auto Scan results, I will ask if anyone can guide me on the next step for troubleshooting?
- Is it possible to have a fault, say in the driver door, that is still recognized by the CAN gateway but has a broken wire or bad module? Perhaps I still have a broken wire buried in the driver door I just cannot see (old bellows style doesn't give much room to look) and the remaining single unbroken wire is enough for the door latch to report back to the CAN gateway?
- Anyone see a central electronics control module go "bad"? Seems unlikely, just odd that every single module is reporting in fine but the DTC for one wire mode is still present.

I found a TSB for the airbag DTC, looks like a high connectivity resistance under the passenger seat that the TSB is guiding the tech to wire around the questionable connector. I don't see that causing this. The DTC for the steering angle sensor is likely from having had the battery disconnected. A recalibration once the issue is resolved should take care of that - again, thinking that is not going to pertain to the battery drain either.
Thanks in advance!
