94 SL 500 ABS/ASR Lights

Just recently, my ABS and ASR lights have started coming on for no apparent reason. Restarting the car eliminates the lights, but at some random point, they return. It should be noted that a shimmy eminates from front rotors when brakes applied normally. This is new also. Any correlation? Had a friend with a code dx access computer. Code #3 and #11 lit. Any suggestions?

THANX

codes are:
# 3 = Lambda control faulty
#11 = TNA-signal (rpm signal) faulty

When I read Ralph's post, I assumed he meant those codes were from the ABS/ASR controller. If those are the ones you need, go to this part of JimF's site: http://pages.prodigy.net/jforgione/MB_ABS.html
