Steering column lock vacuum valve "84" 300TD
 

I followed this links instruction. http://dieselgiant.com/repairignitionlock.htm

After reinstalling the ignition and steering column lock the car will start and run for about 3 seconds then it shuts off. I’m 100% sure that this issue, has to do with the steering column lock vacuum valve. If I physically hold the ignition vacuum valve and press in the piston to release the vacuum pressure the car will continue to run. If I release the piston then the vacuum builds and the engine shuts off

I don’t see what mechinism in the steering column / ignition that presses the piston in when the key is turn to the on position. Do you sell the mechinism that would ingauge the ignition vacuum piston?

Thanks
