Reported: 1993-04-28 (April 28, 1993)
DURING THE REMOVAL AND INSTALLATION OF THE AIR FILTER HOUSING WHILE SERVICING THE VEHICLE, IT IS POSSIBLE TO MISROUTE THE PREFORMED VACUUM HOSE AND DAMAGE THE CHECK VALVE IN THE VACUUM HOSE. IF THE CHECK VALVE IS DAMAGED, LOSS OF SUFFICIENT BRAKE POWER ASSIST WILL OCCUR.
Consequence: LACK OF SUFFICIENT BRAKE POWER ASSIST WILL INCREASESTOPPING DISTANCE AND COULD RESULT IN A VEHICLE ACCIDENT.
Remedy: REPLACE THE PREFORMED VACUUM HOSE WITH A NEWLY DESIGNED PREFORMED HOSE WITH A RELOCATED CHECK VALVE WHICH WILL ELIMINATE THE POSSIBILITY OF THE CHECK VALVE BEING DAMAGED.

WHILE DRIVING, MY 1991 500SL CONVERTIBLE FOR NO APPARENT REASON WILL NOT ACCELERATE AND THE ASR LIGHT COMES ON. IF I SHUT DOWN AND RESTART IT GOES AWAY BUT WILL COME RIGHT BACK IF I GOOSE THE GAS AT ALL. THIS HAPPENS A LOT!
