The button at the top of the lever, the switches among different functions of the trip computer doesn't work anymore. The trip computer works fine, but the trigger simply does not switch. Since it is all "sealed", at Peugeot Assistance they told me they got to change all the levers system (right and left one) by the steering wheel...for an awful amount of 450 euro. Can anyone give me a hint on how to work it out, without paying the big ticket?? Many thanks
