Ok in that case this is not a common problem. Take a look at fuse D7 in case....As you can see on the wiring diagram the spoiler system use two relays. One for the extension one for the retraction. Can the extension one be at fault, may be. I cannot found the year of your car in your profile but this is a diagram for the MY2002. Those spoiler relays are located on the relay support #2. The relay support #2 is located besides the ecu behind the left rear passenger seat. See third pics. And on the fourth pic the actual relay carrier. Those relays are not too expensive and some are interchangeable..... Also the extension signal before it reach the spoiler system goes through the instrument cluster. Do you have a durametric? You should begin by trying a master reset since a triggering message is missing here. Got your radio code? Disconnect the battery....

will try and see if this happens,but if the relay was no good would it still go up and down with switch inside the car,as said the spoiler will go up and down all day long with the switch in the car but will not go up automatically at the 75 mph speed reached the car is 2001 many thanks mark

I agree with you Mark but always depend of the logic inside the cluster computer. Of course we don't have access to this information. The signal goes in , something happen, and the signals goes out. What happen in there depend of the "and" gate or the "or" gate. In the wiring diagram you got the manual switch which goes to the cluster and ???? But after a night of rest I consider the triggering signal is at fault. Which comes from the cluster.....Try the "master" reset and will see. May be we will learn something new...

I have to admit I was a bit confused by the first statement "when i reach 75mph the sign on the dash will come up saying not working but is up" because when you trigger this fault you have to reset it with piwis or durametric... Anyway, give it a try....

The relays are under the rear parcel shelf in the cabriolets.

 

I just had the same issue with my rear spoiler. The dealer suggested that I need to replace the whole system at an installed cost of £3,000. 

I insisted that first of all they replaced the micro switches which are taped into the wiring loom, but this didn’t work. They then checked the relay and it turned out the contacts were a little corroded - new relay and now all’s OK.
