I've searched all the forums, and could not find any additional information. In need of assistance.

My driver side door sensor stopped working. I ordered the correct part, and installed. The door sensor did not work. I read some posts where some people replaced one, and needed to replace the sensor in the other door. So I replaced the passenger door sensor as well. Still does not work. Is there something I'm missing? Is there any other reason why the door sensors would not work? Any help is appreciated.

How did you troubleshoot the issue...how do you know it was the driver side sensor? Did you VAG-COM to get codes, validate they were related to the sensors, or perhaps pointed to something else? What part number, is it correct for your VIN? There isn't much to go on here. Codes and other specifics would help considerably.

I read through the forums, and found that many other people had the same issue, and replacing the door sensor resolved it. Part number I ordered was 4G8927753A/B (A - Passenger Side/B - Driver Side) from Genuine VW/Audi Parts. I included my VIN in the order to make sure I was getting the correct parts. As far as codes - I did use the VAG cable with my laptop, and saw codes, but they were for my ABS & Park Brake, which recently came on. I can hook up the VAG again, but what codes would I be looking for?

GBW

I would auto-scan the entire car...takes about 5 minutes and goes through all the controllers, save the codes to a notepad file...this is your baseline. I would then clear the codes and see if any return after a few days.

Go through your baseline and see what issues you have.

Also, there is a VIN split on the part number you provided....is that the right part for your car...that sensor is to VIN 8T8029964

Yes - my VIN falls in the range of VINs covered by the part. I'll plug up my car some time today and see if there are any codes that need to be cleared.

Stock Boy

The codes were in there. I cleared them. The passenger side works, and the drivers side won't lock, but it will unlock intermittently.

GBW

Can you paste the codes? Were they all on the left side?

Stock Boy

They were on the right and left side. I'll post when I get my car back from the mechanic. I didn't save them to my computer.

Mine started acting up as well and I read that if your battery is weak in your key fob, that will cause your keyless entry not to work since it picks up signal from your key fob. I bought a new battery, put it in my key ob and now no more issues.

I believe his case is slightly different. His key fob probably
still works and probably enables/disables the security component of the smart key. What it's not doing is triggering the electronically controlled mechanical actuator within the door panel itself. Usually it's just a servo arm within the actuator that has slipped off (perhaps from too much slamming and/or door internals subjected to extreme cold) and that arm has to be slipped back on. This type of fault is often linked to or associated with a faulty door handle touch sensor.
There's a good How-To repair for this in the A/S/RS5 Owners page on facebook.
