Hello everyone!

 

I've got a quick question relating to the replacement of the tailgate lock in my Kodiaq.  Came back home last night, and pressed the button to open the tailgate, heard the long beep and the boot never opened. Tried few things (opening it with the key/door button/tailgate button/waving my foot) and nothing worked. After trip to Skoda Aberdeen this morning, the mechanic initially said that it's going to be easy to unlock it from the inside, but after good 5 minutes, the door was still closed solid. He finally used his fist and bumped the tailgate where the lock is and hey pronto - the boot opened.  We then opened and closed it few times, it seems to be working fine (the struts seem to be doing the work) but the tailgate does not close fully - it is up by 2-3mm, there is still a message on the dash that the boot is open.  We then tested it few times and came to conclusion that the lock is faulty and need to be replaced.

 

As I will need to take the car for a long drive over Christmas, and there is no chance to get the car booked to get this done by Skoda, and my friendly garage I used in the past is closed for Xmas already, I will attempt to do this myself - TPS had the replacement lock, and I have already found some information on the forum how to take off the plastic trim - so hopefully not too difficult.

 

However, I was wondering:

1) Is there a service manual available somewhere that would explain step by step what needs to be done?

2) Is there any coding required after the new unit is installed (or perhaps even before I take the old unit out?). Only asking as I remember when some repairs were done by the garage (namely replacing rear brakes and replacing Haldex oil) they were using VCDS to make some changes. Is that required as well with the tailgate lock replacement? I've got an access to VCDS, but have not used it really in the past, so hoping it's a simple parts swap and no programming required?

 

Best Regards,

Raf

Have you tried lubricating the lock mechanism?  It might just be jammed / stiff.

I have used some GT85 (with PTFE) and looks like the mechanism closes, but fails to do the "close assist" function - so it doesn't tighten the tailgate against the body (+light on the dash for open tailgate). Seems like it opens normally, but again, that's opening now from not fully locked position. 

Also, just wonder if it's just the lock mechanism that is faulty - it appears there is also a servo-motor for the soft-close function of the door?

I'm planning to start changing the lock tonight - any advice before start? VCDS coding required? Any other tips? All help hugely appreciated!

No coding required.

 

unbolt and replace, align new one, sorted.

Thanks! So far I managed to take half of the plastic trim off, the other side (next to the window) is stuck solid. Oh well, tonight is another night

New lock installed, unfortunately it works just the same way as the old one. The tailgate goes down but it is not locking properly - it sits 2-3mm above it's final position and dashboard still shows open tailgate...   So it looks like it's the servo motor (attached) for the soft close that needs replacing...    Is there anything I should know before replacing that? Seems easy enough, 4 plastic fittings holding it, one electrical plug and the cable that needs to be adjusted.... Again, not sure if there is anything to do with the VCDS?

 

 

I have also borrowed VCDS and found some things...

 

1) In the series of the sensors on the bottom, one of hte sensors (IDE09519-MAS09067) seems to be showing 1. I think when I open the tailgate all of them are ones, which would indicate that tailgate is open - but when it's closed, this sensor still shows that tailgate is open?

2) this other fault seems to be confirming the servo motor failure? This error appeared on the day when I couldn't open the tailgate

3) This is other fault seems to be pointing to the rear lid opener control module - but this error was logged back in September, so not sure if this is relevant ? (if memory serves me right, there was one time when my battery gone a bit low after car was sitting for few weeks, and I had to recharge it, but cannot remember if this was around the same time)

I really hope it's the servo motor .... after a bit of reading last night realized it could be also the foot sensor, or the sensor in one of the struts... Asked local TPS if they got the struts just in case... they don't stock them, and the guy said - they are quite expensive, each is 570 (or 507, I think I've fainted when he started "five hundred... :D:D:D).  Hope it's the cheaper option!

Replaced the servo motor, in temp position now, it works! Tailgate closes, and soft-close locks the tailgate, then the light on the dash (boot open) disappears .  Before I put everything back together in final places, is there anything in VCDS coding that needs to be done to this module? Checked all (I think) the service manuals and this servo motor is not shown anywhere, so no idea if there is any coding/basic setting to be done? Would be good to know so I don't end up breaking the new (£132) part shortly. 

quick update, friend from VW garage confirmed this is plug-and-play part, so all good. Just need to put it all back together, make sure all works correctly ... just in time for Xmas!

Excellent...   Looks like a result!

Hi there,

 

im having the same issue with my kodiaq sportline (2018). Do you have any additional photos to remove the trim etc? Any extra info would be greatly appreciated.

 

thanks

Unfortunately not, but I think I was using Skoda manual which is downloadable on this forum (

). 

From memory, the clips were sitting very tight and I tried to pry them with multiple plastic tools - as I was worried that I will break something. Eventually, one clip popped-off and it was then a bit easier to remove the rest of the trim...
