1999 Audi A4 6 cyl All Wheel Drive Manual 147000 miles

Please help. The power door locks do not work at all anymore. I can shut the alarm system on/off with the remote but the locks do not move. They will not move by pushing the interior door lock button on the drivers side door either. Checked the fuses, they are fine. What is the problem, and if it could be multiple problems how do I check which one is correct? Thank you.

Do you
have the same problem?

Hi, I tried that already. The car cannot manually be locked/unlocked using the button on the drivers side door. So it's not synchronization. What else could it be? Thanks.

Yes they do, but only the door that I put the key in. They don't all go up or down together. Thanks.

"have you tried the synch using the key to lock the door after sing the button on fob?"

I apologize, but I'm not sure what you mean by this. What is "fob"? Thanks.

I'm sorry .. my english term's coming out !! .... the "fob" is the device (remote transmitter)that has the buttons on for opening the doors/turning alarm on/off etc.

1) Press any button on the remote transmitter for 2/3 seconds

Within 30 seconds Lock or unlock the drivers door using the key in the lock

Have you tried this way ??

Let me know

Yes, I didn't hold the transmitter button for 2/3 seconds, but since the car won't lock/unlock manually (via the button on the drivers side door), doesn't that basically mean that it's not a synching problem? The button should still work with the locks regardless of whether the remote is synched, correct? The remote turns the alarm on/off but not the locks, and the locks won't open/close at all using the remote or the door button. Thanks again.

Hey Groovis.

I was just making sure all base's were covered ! I have listed the most common faults on C/L system and causes you will need to check these !! of course the fault could be in the control module .. so it really could also do with scanning with a VAG diagnostic scanner !!

DTC 01360: DRIVER'S DOOR SWITCH
NOTE:This DTC is usually stored because of improper use of alarm system. Only carry out repairs if a complaint exists, otherwise just erase DTC. See FUNCTION MODE 05: ERASING DTC MEMORY under SELF-DIAGNOSTIC SYSTEM.

Possible Cause
Short to ground in wiring. Faulty driver's side door switch.
Corrective Steps
Repair short to ground in wiring. See WIRING DIAGRAMS . Replace driver's side door switch if necessary.
DTC 01361: PASSENGER'S DOOR SWITCH
NOTE:This DTC is usually stored because of improper use of alarm system. Only carry out repairs if a complaint exists, otherwise just erase DTC. See FUNCTION MODE 05: ERASING DTC MEMORY under SELF-DIAGNOSTIC SYSTEM.

Possible Cause
Short to ground in wiring. Faulty passenger's side door switch.
Corrective Steps
Repair short to ground in wiring. See WIRING DIAGRAMS . Replace passenger's side door switch if necessary.
ENTERING ON-BOARD DIAGNOSTIC FUNCTION MODES
NOTE:Additional operating instructions can be obtained by pressing HELP key on scan tool. During test procedures, the right arrow key advances program to next step. An incorrect entry can be cancelled with "C" key.

DTC 01367: CENTRAL LOCKING PUMP
Possible Cause
Pressure in air lines too low. Faulty central locking pump.
Corrective Steps
Check air lines for leaks. Check central locking pump. Check all actuating components of central locking system and replace as necessary.

Ensure battery is fully charged, fuses are not blown, and ground connections are okay. Ensure all accessories are off. Using Adapter Cable (VAG 1551/3), connect Scan Tool (VAG 1551) to Data Link Connector (DLC). If V.A.G SELF DIAGNOSIS HELP 1-RAPID DATA TRANSFER 2-BLINK CODE OUTPUT is displayed on scan tool, go to next step. If V.A.G SELF DIAGNOSIS HELP 1-RAPID DATA TRANSFER 2-BLINK CODE OUTPUT is not displayed on scan tool, check battery, fuses, ground and scan tool for proper connections.

Hope this helps, let me know !

OK, this is what I was looking for. I will get a diagnostic run and see if anything comes up. Then I will take it from there. I'll get back to you in a few days.

Thanks very much for your help. Will be in touch.

OK, had a diagnostic test performed with no error codes coming up. It may be a "short ground to wire" issue. What is the best way to figure out where the wiring issue may be?

PS, I'm going to try my other remote to see if it is a malfunctioning locking unit. Thanks for your help.

I would start at the drivers door switch as this controls all doors ! But I would still expect the other switches to work? You could check power and ground at pump !

Possible Cause
Short to ground in wiring. Faulty driver's side door switch.
Corrective Steps
Repair short to ground in wiring. See WIRING DIAGRAMS. Replace driver's side door switch if necessary.

For some reason I do not have a wiring diagram for the power door lock's. I will try and locate one and get back to you !

Found the problem with the locks. It was the Central Locking Control Module. My friend and I took it apart and found that the graphite compressor wheel was broken in 3 pieces. The unit was still working but the pump wasn't creating any suction to move the locks up/down. This is probably why no error code came up when I scanned it.

Anyway, gonna try to find the part at a junkyard and replace it. Appreciate your time helpingme. Thanks.
