Hi Experts ,

Can someone please advice if VCDS can help to investigate the button locking issue - this button does not lock any/all doors , no relay sound is heard when it is clicked ( possibly relay if yes then please advice location of it ), but the button behaves fine with unlocking behaviour and surprisingly the button also glows LED when doors are locked form outside with mechanically key. Car Key Fob is also NOT working .

This issue is making unpredicted behaviour of car it gets automatically locks itself and cannot be even opened mechanically with KEY ( fortunately I keep one/2 glass down so that we can unlock using inner handle . Is it faulty button switch or Body management controller any thought also any approach to disgnosie issue using vcds .

VCDS shows door lock/unlcok open/close all option works as expected

Any input would be highly appreciated.

Thanks

Kind regrds

.

Looked the BCM part seems fine for car , but can we test and check the coding of it? . Any thoughts please on approach ? Anybody can share screen shot of configuration please ?

Analysed and found issue with resolution plan : This was achieved using VCDS in my case central locking button switch was not locking doors but unclock was working fine so I have tested live data of ECU and found that the button when clicked for locking is un-operational in VCDS status means button may have circuit/ mechanism issue or soldiering issue . please find attached screen shot it may help , the live option was inside under number 9 Cent Elect option I think.

Thanks kind regards
