Passat estate boot lock fixed

[jenny35]

I had a problem with my boot lock on my X reg (2000 model) passat estate in that it wouldn't lock with central locking. Found out it was the solenoid & thought i'd let all u folks know that u don't have to buy the whole locking mechanism, u can get the part from VW & only costs £13. Part number is 1MO 959 781 A. Got my mechanic friend to fit & only took about half an hour. Hope this helps somebody

I seem to have the same issue with my 2000 W Passat saloon, the boot lock works with the key (to dead lock it) it is pretty stiff, the actuator isn't operating but at least I can secure the boot. Will have a look at the internal workings in the week. Thanks for your info.

Hi
My B5 Passat estate 03 reg. tailgate lock worked fine for a number of years but now it's stopped.
It actually locks when you shut the tailgate and it opens manually with the key.
I took off the trim and operating the solenoid mechanically by hand opens the lock ok but it does not operate with the key fob or the inside door switch.
I used a meter and I am getting a reading across the solenoid of about 3 Ohms which I guess could be OK. I also checked across the micro switch on the back of the lock unit ( Not quite sure what this is for ) and I got a reading of 183 Ohms which I presume is possibly to high.
Not knowing how the system works leaves me at a loss.

Is there anybody out there that could provide a link or a work through to help me locate the actual problem?
P.S.
The unit under the passenger side carpet was replaced a year ago because of a flood and appears fine now as all the other doors lock and open OK.

Cheers Kev

Had a similar problem on my 52 reg Passat estate. Decided at £23 it was worth changing the solenoid just to see if it was the problem. It was, and now works with the remote.

It's not too difficult to replace just a little fiddly, especially removing the solenoid and the part it's screwed to from the hatch.

Rather than creating a new thread, how do you replace the solenoid? Does it involve removing the whole handle and locking mechanism?

on my saloon there is just 2 bolts holding it in then it pulls off the rod.

[KieranM]

On mine (B5 Estate 97 tdi 110 AFN) The bolts are facing toward the rear of the car, so it looks as if I would have to take the mechanism off juist to undo the bolts.

I noticed that I had some corrosion in the pins to the lock sensor, potentially this could be a problem (I liberally sprayed some GT45 as I could n't find my WD40 at it, so hopefully that'll help), or could also be related to my CCM wirings, maybe?!

yep my bolts are the same, i just put a small pair of mole grips on them and turned them out and off it comes.

[KieranM]

I can't take mine off using mole grips, the bolt head is too tightly packed and the thread is too recessed to get any purchase on it. What a daft idea putting them that way round!

On a brighter note, it's definitely the solenoid as I tested a new one and it worked!
