Central Locking Control Module - Board Help.

[pjd131]

Trying to tackle central locking issue (not working). This is part 91161811301 out of an 89 911 3.2. If anyone has a pic or a unit about, could you please post a picture of the board. A friend noticed an apparent solder break. Not sure what this is, but it doesn't look right. This may be a Hail Mary, but worth a try. Thanks.

Board with potential issue.

Very common break, your friend is right, solder that piece back and I bet your system will work properly

Thanks for your response 964TargaC2. You happen to know what it is. Not critically important but just curious. I'll clean it up and solder it and give it a try then post the result. Thanks, Paul

Yes, cold solder joints can be very elusive.

Hope this helps.

Best,
