Hi, I’m troubleshooting central locking on a 2008 Golf 5 (1.6).

Symptoms:

• Remote key adapts successfully in VCDS
• Measuring blocks show signal (0 → 1) when pressing remote
• Hazard lights blink during adaptation
• But no lock/unlock action occurs at all
• Interior central locking button works (except one rear door lock module is faulty)

What’s been done:

• Steering lock was replaced recently
• Battery was disconnected during that work
• Full battery reset performed (including discharge)
• Ignition (Terminal 15) is recognized correctly in measuring blocks
• No obvious communication issues with module 46
• Oil change etc. irrelevant but done recently

Issue during adaptation:

• “Save” button in VCDS was grey / not always clickable
• Unclear if remote slots were actually cleared (Channel 00) and written to EEPROM

Other notes:

• One rear right door lock module is faulty (does not lock/unlock electrically)
• Not sure if that could block remote execution entirely
• Remote signal is definitely received by the comfort module

Question:
What could cause a situation where:

• remote signal is received
• adaptation appears successful
• but central locking does not execute?

Could this be:

• adaptation not properly committed (EEPROM issue)?
• comfort module coding problem?
• door module blocking execution?
• something related to steering lock replacement?

Any ideas or known Golf 5 quirks appreciated.

Hiya.

A few days ago the LED on it stopped lighting on button press, and I didnt investigate it at that time.
Today - changed batteries to brand new (1.55V) - no joy, as they say at Nasa.

Hasnt been damaged, nothing loose when shakin against ears.
Is within warantee, obviously... but.... "hmph".

Update: (pasted from below)

"I had my remote changed out for a new one, inserted the batteries and... turns out the LED no longer lights up when a button is pressed. Re-paired, and it works as normal.
The reason why i though it was dead was because the first remote also had unpaired, lost connection, so buttons didnt do anything.

So, basically Wiim, via some supposed update managed to confuse the hell out of me, and I obviously sucked at trouble shooting it properly."
