The mechanism I replaced is still sitting on my workbench, so I took it apart. Tested all the microswitches in it, and they all worked fine. The circuit board is covered in some sort of orange glue. My guess would, it was a fix VW rolled out to address exactly what he found. Broken solder connections. For fun I'm going to resolder the whole board and test it. What could it hurt? May do the same on the passenger side.
any luck sesn

I haven't had time to dig into the PCB on the mechanism. Been working like 70 hours a week. However, with all the extra work, I finally had the money to order a PC based laptop and durametric. Just ordered it about an hour ago. With it, I think I can dig a little deeper.

Swhitcomb 06-08-2017 04:47 PM
Well, my durametric cable came today. I hooked it up and read the codes. There were 10 or 12 of them. Like a dumbass, I cleared them before I screen shot it. None have returned yet. What's weird though is none of the activations would work on the alarm module. I only played for about 10 mins. This weekend I'll dig farther.

Swhitcomb 06-15-2017 05:37 PM
Well, some of the codes came back. I downloaded the diagnostic manual and can't find the flow chart for error code 60 or 49.

Hi had a chance to play today did all switch testing all ok all connections good. I have the same mechanism as you Sean cm2. Still no luck once the Immobiliser kicks in loose all power until I open with key and turn ignition on

Found this website scroll down to section 90 for Immobiliser fault finding v12.dyndns.org

Has anyone been able to figure this out? My factory remote recently gave up the ghost as well and I turned to Ebay for an aftermarket solution. I have an 02 Base and after wiring up the unit, I can also get the doors to lock and unlock. Unfortunately, similar to the previous posts, once the dash LED kicks on (30 seconds after the door locks), I cannot unlock the doors using the remote. I have an M535 immobilizer.

Thanks in advance.

Swhitcomb 05-01-2018 04:11 PM
That actually makes me feel better. Maybe it’s something in the M535 that causes it not to function the way it would with an m531.

I know I'm repeating myself, but it shouldn't be any different than locking and unlocking using the key in the door. If the key didn't work in the door after 30 seconds, that would cause some serious issues.

I wish one of you guys were closer to me so I could solve this thing once and for all. :(

That makes 2 of us. :)

Yep, definitely something to do with the fact that it's an M535.

I can unlock the driver door manually with the physical key but I have to put the key in the ignition within 10 seconds or the alarm goes off.

Swhitcomb 05-02-2018 03:05 AM
Mine does exactly the same thing.

particlewave 05-25-2018 09:52 PM
Sean - do you still have that list of trouble codes?

Swhitcomb 05-26-2018 05:15 AM
I can pull them when I get home from work.

particlewave 05-26-2018 11:51 AM
I can see it now. The picture wasn't showing up last night.

I was going through the 2000 or so pages of the workshop manuals and thought I'd do some more checking. I doubt any light will be shed, though...and it looks like you have already looked in them.

That is normal if you don't / can't use the keyfob to open the doors.

You have to turn the key in the doorlock to the right for approx. 10 secs and hold it there. Than turn the key left and the central locking system will open the car. Also the alarm system is deactivated.

You can try to resync the keys to get the original keyfobs to work again.

Or you could just unlock normally and insert the key within 10 seconds...seems like this would be the easiest route in most cases.

Difference is, that the alarm system is still activated, which leads to a lot of DTCs.

Thanks exactly what I have to do - unlocking with a physical key and inserting the key into the ignition within 10 seconds. Unfortunately, the remote doesn't unlock once the alarm arms. Only the interior lights light up.

None of the key resyncing procedures I've tried have worked...and I've tried all of them.

This is exactly what mine does.
