Het OD relais de baas over het lampje, ik zou daar beginnen. D andere spelers in de OD wereld zijn allemaal schakelaars type aan/uit, als die stuk zijn merk je dat direct. Misschien heb je hier wat aan:

O/D Relay. [Duane Hoberg] Relays for the manual trannies rarely fail, whereas the automatic tranny relays drop like flies after a frost. Manual transmission relays (blue) and automatic relays (white) are two different devices and ARE NOT interchangable. To diagnose a suspected relay problem, watch the reaction of the dash light. If the dash light illuminates when you push the button on the shifter, the relay is OK and your OD not engaging is caused by something else. IF the dash light does not come on, you have either a blown fuse or a 4th gear switch that is not working. Plug your relay in and with the engine OFF, ignition ON, shifter in 4th, try to engage the OD. If the dash light comes on, does the solenoid by the OD unit click at the same time? If it clicks and still no OD, you need new actuating piston seals to get your OD working again. If the dash light does not come on, pull the shift lever further to the rear and right and holding it there try the button again. If the dash light comes on then goes out when you move the shift lever, the 4th gear switch is bad.
Bosch relays can have a habit of becoming intermittent and/or temperature sensitive due to solder cracks on the boards. See the FAQ file on relay resoldering if you need to do this.
