Problem with the automatic tailgate on Audi A4

I have a problem with my Audi A4 tailgate. It does not open automatically and can only be opened with the key. It also closes automatically after about a minute. Which safety function could be set here and why? What do I have to do to restore the normal state?

It sounds like your tailgate's automatic opening and closing mechanism might be malfunctioning. This could be due to a faulty latch, a problem with the wiring, or a malfunctioning control module. Start by checking the fuse for the tailgate in your car's fuse box. If the fuse is blown, replace it. If the fuse is fine, the next step would be to inspect the wiring and the latch. If you're not comfortable doing these checks yourself, I would recommend taking your car to a professional mechanic. The tailgate is a crucial part of your vehicle's safety system, and any malfunction could potentially be dangerous. Please let us know how you get on with these checks, or if you have any other questions.

Since the door closes automatically, the fuse and wiring are probably OK! The question is, are there any parameters or alarms in the control unit that prevent the door from opening via the door contact? Are the tailgate drives misaligned and if so, how can they be adjusted? Another question: Who are you, CarlyMechanic? Just software??

I need help with my A4 B6. I have a problem with the doors; two of the doors won't open from the inside or outside. Only the front two doors lock/unlock with the key; the rear doors don't work. I don't know what to do!

Start by checking if the child safety locks are engaged on the rear doors, as this could prevent them from opening from the inside. If the child locks are not the issue, the problem might be with the door lock actuators or the central locking system. Try manually unlocking the rear doors from the inside using the lock switch, if accessible. If this doesn't work, you may need to remove the door panel to inspect the lock mechanism and actuator. If you're not comfortable doing this, it's best to consult a professional mechanic. Let me know how it goes or if you have more questions!

No. I didn't lock it with the child lock, so I couldn't open it once. I closed it today and couldn't open it with the two front keys.

Try checking the central locking system fuse in the fuse box to ensure it's not blown. If the fuse is intact, the issue might be with the central locking control module or the door lock actuators themselves. You may need to access the rear door panels to inspect the actuators for any signs of damage or disconnection. If you're unsure about handling this, consider seeking help from a professional mechanic. Let me know if you need further assistance or have any updates!

Could you tell me which insurance lock control is on?

The insurance lock control, often referred to as the central locking system fuse, is typically located in the fuse box. For the Audi A4 B6, you can find the fuse box on the driver's side dashboard or under the hood. Refer to your owner's manual for the exact location and the specific fuse number related to the central locking system. If the fuse is intact, further inspection of the central locking module and door actuators might be necessary. Let me know if you need more help or have any updates!
