Title: Driver's door sometimes doesn't unlock with the remote (not battery)
Post by: Ytee on November 02, 2020, 02:51:03 pm
Hi all.

My mk5 GTI recently developed a weird and extremely annoying issue. Sometimes (initially it was occasional, now it's most of the time) the driver's door does not unlock along with the rest of the car when using the remote. I need to use the key to unlock the driver's door. All other locks work fine. Car starts and drives normally. When removing the key from the ignition after stopping the engine though, the drivers door doesn't unlock like it used to either, I have to pull the door handle twice.

"Change the remote battery!" I hear you scream. And I have... twice. It helps for a few goes, then it just stops again. It happens with both remotes as well.

If it was consistent, I might think that the remote needs re-registering... but that's the thing... sometimes it works perfectly fine.

Am I right to suspect the the infrared receiver in the car? If so, how easy is that to replace DIY?

Cheers.

Your drivers door lock module has failed and needs to be replaced or the wiring at the door hinge is broken.

Yep, makes sense. My garage seems to agree so I'll get that changed. I don't have the daylight time to tackle it myself at the moment sadly... thanks for the tip.

I've got exactly the same issue and it's been intermittent for a while. Changed the battery and I thought it went away, but randomly every 1 in 20 days or so, it'll happen again.

If you've got any links to parts that need replacing, I'd appreciate it also
