Hello All,

On our beloved 2009 EOS Lux, the convertible top stopped working. We bought the car in 2011 and had only minor issues with the headliner only folding 90 degrees instead of the required 180 degrees after the rear window part opened. That was fixed by VW.

My wife came home a couple of weeks ago and while closing the top it stopped working with the boot lid open and the roof frame lifted half out of the trunk. She stopped the engine and waited for me to come home. I found the roof as described above.
I tried to close it but it didn't work with the switch. It took a while and I was able to manually close the top. When I operate the switch to open the top a message comes up in the centre display:

System fault, Convertible Top, Workshop.

I made sure the roof is locked and we continued to drive the car.

Now I want the roof repaired for spring.

I used VAG Com and got the following codes: G560, G562, and G558 all implausible signals.

The measuring block 002 showed: HS1: 11G1G1100G100:HS13

The "G" shows the implausible signal on said sensors.

After reading through SSP 379 I read that only G562 causes the roof operation to stop, even emergency closing of the roof because there is only one of these sensors where all others are pairs of sensors.

Another clue: all sensors affected are on the left side of the car.

So I think the problem is either around hall sensor 562 or it's a wiring problem affecting all three sensors on that side.

Unfortunately, I could access his pictures with all roof coverings and headliner pieces removed.

My trunk is pulled shut when closed.

Any suggestions from the forum if I missed something in my assumptions?
I looked at Silvershadows post about his roof repair.

Thanks for your help.

Seems like you did your homework already. I know of reports from people finding strange objects in the boot which had to do with the hall sensors, magnet etc. and their roof not working. Just fell of and glued back again and the problem was solved.
In later FL models the, I think 562, has been duplicated also to the right side!
The implausible signals from the others sensors may as well be because you manually closed the roof.

 

[Shep]

Hmm. Mine stopped working also.

Though it doesn't show on that, But I have a V for that halls sensor. Wonder what the G and the V mean, and what's the difference.
I'm suspecting broken wire at the splice on the left side of the car.

 

[Shep]

I notice that when the plug for the sensors is unplugged it turns into a G, so looks like you have a broken wire.
Spent ages on mine, still no further. Could do with plug pin diagram, but every loom just disappears into the roof, is wrapped, and is dam near impossible to check it for damage. Started pulling bit of roof trim off, but VW don't want you to do that and the more you look the further in the pooh you get.
Just have to keep my laptop in the car and use it to open the roof, far easier than trying to repair it.

You might be miffed at what you have to do to execute your repair, but I wish all my diagnostics faults were as credible as yours: Wire or sensor dead, remove headlining and fix sensor or wire. Their Hall sensors are usually 3 wires: + 5 volt supply and ground with the third sense wire 'output' either near +5V or Ground when close to the magnet or steel. If you have to remove the headlining (without breaking it) we expect a full write up with photos!

Before you start taking things apart, check for those faulty sensors that you do have a +5V and ground coming from the roof controller. Compare with one of the other working sensors that I'm right about how they work.

That's the trouble with diagnostics, whilst it's highly probably there's a wiring or sensor fault, if the roof controller module has damaged connector pins, water damaged tracks or wires broken in the connector, you will get the same fault code. Faults on more than one sensor would suggest a broken common ground.

Hello All,

I fixed my roof yesterday.

As suspected it was a broken wire at the point where sensor 558, 560 and 562 meet and change color from yellow to red/wht.

I worked from the outside and left the headliner alone. The rear window was up. Boot lid closed.

It's the wiring harness that runs from the control module up the left roof support bar. The harness runs right under the water run off. The wire split location is right under the rear window water runoff (see pictures).
VW uses a metal sleeve that is pinched to hold the wires together.
I unwrapped too much of the harness. I cut 10 cable ties to get some slack in the harness.
I reconnected the wires (confirmed with VAG Com), rewrapped the harness, replaced the cable ties and cleaned up.

Let me know if you have any questions.

Well done. I thought yours might have been that joint, was going to look at that side myself. Mine is the other side, so do I go that side or the side you done, decisions, decisions lol.
Forgot, cheers for the pictures, well helpful.

Alas... can you elaborate on this? I had a really "fun" time dealing with my non-closing roof today.
Incidentally, I fixed my roof today as well, but the problem was NOT on the three-to-one splice, but where VW decided to splice the wire coming from the sensor (brown) to the harness (white). I'll write something on the thread I started late last year (here).

In any case: THANK YOU for the pictures!!!

Everything you need to know about future EOS roof wiring loom problems is here. You may fix one common tap, but there are plenty more waiting to fail! I've now found and replaced every single roof wiring joint, tap and splice in my EOS roof wiring loom with soldered and double covered heatshrink joints. These are then wrapped with cloth tape and soaked with acrylic lacquer. Every sensor of 12 (or 13) has two splices to the loom wires, additionally there are some crappy hidden 2 pin connectors and several taps for 'commons' split into groups, with some interlinked to each other. And that's before you get to the roof controller plugs!

The write up for ODIS and VAS would be helpful, but it's only any good for a sensor type fault when there's still diagnostics communication. Diagnostics won't help if the roof controller or pump is bad unless you did my 'jailbreak' mods, because software won't communicate and a faulty pump can't drive anything, including the trunk lid and roof 'C' locks holding it closed.

Hi - Thanks for the info. Is there any chance you can post the photos of the "General Location", "Harness Before", "Harness fixed" and "Sensor 558". I was unable to access them. Thank you for all the information you provided.

As every EOS gets older beset by internal condensation and seal leaks, the chances of just one wiring fault in the roof sensor wiring become greater. One wiring fault can cause a roof stuck out on the road with no easy fix and you never know when it might happen. If you spend time unwrapping the loom and going through all the EOS wiring taps and juntions like I did in post #11 you will avoid future intermittent wiring faults. If you find one problem wiring junction following what others did, you will not find the other bad boys!

You start unwrapping the loom inside the trunk left side, up into the roof rear section under the headliner and across to the right, inside the roof top sections and then forwards into each 'A' pillar. The roof needs to be propped open using the V.W service tool or my Vox props to access these wiring looms.

what program you use to open it with laptop ?

 

[voxmagna]

You can try VCDS or OBDEleven but this procedure is strictly regarded as workshop intervention and really not for those just familiar with phones and laptops. The roof operation has stopped to protect itself from further damage and writing off your roof (and car) if you force an operation it wouldn't normally do. The correct fault finding approach is to scan for roof fault codes, analyze the results and consider what has stopped the roof from operating.

There is a manual workshop procedure to open/close the roof requiring two people and you should look at that as safer and less likely to (bend/distort) write off your roof

VCDS and OBD Eleven both have a diagnostics routine to force roof operations with sensors disabled, although the procedure for doing it is partly hidden with warnings given.

The best way to inflict permanent damage to an EOS roof and total the car is using this workshop procedure without knowing what you are doing, what kind of roof fault is present and misunderstand the roof system stops to prevent damage. Moving roof parts manually using 2 people may sound more work than tapping options on a laptop, but it's the safest way for DIYers to start roof fault finding.

If a fault locks out access to the trunk and roof pump, diagnostics may seem the only way to get in. Even if you spend a couple of hours fishing to open the trunk locking claws, there is far less risk of roof damage or motoring itself (hydraulically speaking) to destruction.
