Title: Key fob not wokring - next to try
Post by: Technane on 14 March 2015, 21:34

OK so heres the deal,

Swapped stereo and Keyfob stopped, so thought Fuse, but can't find one blown, then thought key had lost synchronization. but seems not

using VCDS - i ran a measure on the central Conv,  checked how many keys i had, 1 as i thought.
then used an old vagcom and did a new key mapping and the car made a beep when I pressed the button.
which tells me the car picked up the key and acknowledged it.

so then back into vcds - back into measure, found the measurment set that shows which button I am pressing on the keyfob,

and sure enough i can see position 1 and 2 changing when i press buttons on the key

so that says to me

Key fob is fine,
Sensor is fine

so why wont it lock / unlock the car? what can i look for next?

i assume its an aftermarket stereo and you've used an iso adapter. if so the kline is your issue.. its too early on a sunday for me to be technical :grin: so have a look here http://uk-mkivs.net/topic/11361-how-to-upgrade-the-stereo-in-mk4-golfsboras/

Cheers just before the questions come,

Yes its aftermarket
yes i have an ISO adapter on there ..

Ill check the cabling as it is not SWITCHED power which is pissing me off anyway ;)

Ok so my thinking,

if the stereo is disconnected, so if the kline was not being interrupted or connected, shouldnt the locking spring back into life?

as it does not?

noted somone was a dick though and cut behind the original connector, looks like one of the lives has been disconected but i cant see why.

Yeah but surely with the stereo disconnected then it should start working if the stereo is causing the issue?

OK So i've checked with VAGcom and the key re-syncs fine,

I have disconnected the Car Battery for 10 minutes to give it a bit of a reboot,

removed stereo had it sat completely disconnected and still nothing?

Checked all the fuses that i can see are relevant nothing blown

i'm pulling my hair out on this? can anyone think of a series of things to check / try that i have failed to see so far?
