Yes totally understand thanks for the help I don't expect anyone to pull their car apart just to help me ha ha .a friend says he has a rosstech hexcan usb but it seemed very limited on what we can do on the Bentley he was saying that he needed the Bentley code? Does this make sense or is it that the lead is about 10 years old?

 

What part of the UK are you in, as i have the cable and laptop

 

I'm in Plymouth probably a million miles away from you guys I expect

 

sorry 220 miles to far

 

There have been revisions over the years. Also there's a shareware version which is limited. The current version referred to earlier will be an eye-opener. This is the setup other fellows on this forum have been using with success. The latest version is interactive with the modules allowing for adaptation or programming. There for a degree of computer literacy is necessary. The same stubbornness that is required for fixing these cars will lead to learning how to use the program.🤔😉

A guy is selling a VW/Audi garage computer with the above programme with unlimited vins on it.lookinh at the list of things it covers what are the certain things blued out? Are these things that it won't read?

 

This guy is in the UK (Cardiff),go for the 3 vin one its less money but will do the job.

 

Thanks jo

 

Did you ever get this figured out? As 1eapplebaum stated, it looks like your missing a vital piece to your airfoil. In this picture, yours is on the top, mines on the bottom.

 

Ok playing with this spoiler I can get it to go up through the positions then it returns back the rest position closed.not having had one before I'm unsure if what these things do.but now if I drive away spoiler pops up returns to close and the light on the dash comes on is this correct??

 

Hello ... Let me get this right, when you're not driving and lift the spoiler at the switch it should fully open as in lift. when you press the button the opposite way the spoiler should go down in 3 stages to rest. When the vehicle is driven (don't know what speed your spoiler goes up) but when it does it should stay up until you hit the brakes or the vehicle slows to a speed that the spoiler returns to its resting position in one sweep (not in 3 stages) ...

 

It will be a broken wire usually in the LHS conduit ( as you stand at the back looking in the boot / trunk ) .
The ECU module misses a signal and when you ,or if fast enough causes it to activate the thing pops up then defaults closed / down and the light comes on , telling you there’s a problem.

A scan normally tells the tech which wires “ open “ repair is reconnect it .

I guess it’s possible to investigate without a scan and try and eyeball the wires in the LHS umbilical.

 

I can’t be sure but these short movement one direction for up and the reverse for lowering work by coming to a stop while running .
Then as the movement stops the resistance / temperature increases because current is still flowing .
A module in the ECU or control module sensors this and switches off the current .

So may be the BMW sunroof motor is not quite the same internally and the control module can’t tell when to cut the power so it ( too clever ) defaults to lowering the spoiler and throwing a light on the dash .

That might explain why the control arms under the spoiler on the pics have ripped / popped off ?? I

Obviously as said above check the umbilical wires for a open circuit .

 

I think that's a very good theory.

A similar dilemma is the Audi dust cover for the shift lever. It fits and is much cheaper than the Bentley part. However the placement of the magnets are slightly different. The result is the Tiptronic manual shift lever does not function properly. This took a while to figure out.

 

Ok on inspection the motor is exactly the same as one used for the Bentley Samer serial etc do that our if the question I'll go through what it does .if I sit in car ignition on no start,I press up and is raises in three stages then returns to rest closed and illuminates dash light.if I start car and drive it pops up one stage then returns to rest and illuminates light and won't work with buttons .
I will check wiring tomorrow I'm determined to sort this
