Active Spoiler Electrical Issue

[g60jaime 10]

4-6 weeks ago I had a fully functioning active rear spoiler.

 

It then had a new steering rack fitted and a heated seat loom connected up to the fuseboard. On the 60 mile journey home from the garage that did the work i noticed the spoiler wasn't going up and down at the appropriate speeds, but was working using the over-ride switch on the dash.

 

I contacted the garage in the following days who said a connection must have come out somewhere behind the dash but didn't elaborate any further on how to go about fixing this.

 

Therefore I did some research on the forum into the issue and found out the usual, head unit and blue and white cable being disconnected etc. I investigated into the connections at the fuseboard and found a few connectors unconnected. I can not tell what they are or if they should be connected or not.

 

Disconnected as follows:

 

Cable connected to the fuseboard leading away to the car:

Blue coloured female connector with a single blue/white cable

 

Coming to the fuseboard from the car:

Brown coloured female connector with grey/white and yellow cable

Olive Green coloured male connector with black cable

Green coloured male connector with black/white cable

White coloured female spade connector with blue and white cable

Yellow coloured female connector with green cable (connector has capacity for an extre cable)

 

I don't know where to start, all obvious connections to and from the spoiler control unit are fine. I hate electrics and don't know how to fix this once working part of the car, fuseboards are too confusing with all the cables, different colours connections etc.

 

I've tried looking through the Bentley manual but can't find much useful on the spoiler.

 

Any help is appreciated.

Had hoped a non working active rear spoiler would have got a response or two, as it is a seemingly fairly common problem (couldn't find my fault on here though), was hoping for a tip or two.

 

Will be seeking advice from a local auto electirican in the next few days to see if they can help on this and on fitting a new immobiliser unit because the current one gets dangerously hot!

PLEASE SOMEONE! This is a nightmare! I've been out under torchlight investigating just found a whole bundle more unconnected cables. The auto electrician didn't want to know and refered me to a local VW specialist who I've used before and wasn't very impressed for the expensive work they undertook so not confident. The well known specialist who fitted the steering rack have said to check the stereo even though they shouldn't have been anywhere near it when it was last with them, I'm beyond fustrated.

 

I've done loads of research on the forum, its not fuse 16, its not the Stereo as it it worked fine before the heated seat loom went in and steering rack was changed. Still works on the manual button etc........ I've found two unconnected blue and white cables, neither of which seem to have the right connector to plug in anywhere.

 

PLEASE!

I had this exact same problem on my last VR and it turned out to be the blue/white (or was it grey? :scratch: ) cable that was unplugged. Just plugged it in and it worked perfectly after that.

Sounds like maybe the spoiler control module has been disconnected? :shrug:

 

Im no expert tho, lol :lol:

 

My VR's spoiler went down automatically, but not up, and it worked both ways with the manual switch. I changed the module and it solved it. Dunno if its worth investigating?

There is a blue/grey wire, as cazza says.......it is part of the wires to the back of the radio, i had my radio out recently and hadn't connected this, same symptoms as yours, re connected and all was good

hopefully going to get some time this afternoon to look. I just can't beleive the number of cables and what is unpluged to what is pluged in. IT can't be hard, just got to find it. Thanks to everyone will update with findings.

Right, I found that the heated seat cables (1xblack cable with Green terminal connection and 1xgrey/blue cable with grey terminal connection) were interfering with the spoiler. I unplugged them and now the spoiler works.

 

I now don't have my heated seat plugged in and therefore not working. Does anyone know a suitable connection for these to plug into without causing interference with other circuits? thanks

Now have heated seats AND active spoiler. Just plugged black cable (green connector) back in for the seat loom. Does anyone know where to plug the blue/grey cable (grey connector) in? Presume this will illuminate the heated seat switch when i turn the headlights on?
