Help! Problems with both ABC & SRS lights, plus accelarating shudder. Any suggestions?

Asked by Dec 06, 2007 at 11:56 AM about the 2003 Mercedes-Benz S-Class S 55 AMG

Question type: Maintenance & Repair

Since purchasing in 05 as certified/pre-owned, it's been in the shop constantly for 3 issues: #1) the "ABC" light comes on intermittently, the "SRS" light is on and #3) at about 50 mph there's a hard shift that starts a shudder which worsens when accelerating.  Among other things, in addition to normal maintenance, for problem #1 the dealer has performed the ABC hose campaign (#97533), replaced the ABC hydraulic line for pressure supply and the replaced rear ABC valve block. For #2 the seat's been removed & reinstalled. For #3 the dealer has replaced the idler pulley, reset & performed shift adaptation.  Is this common with this YR/MAKE/MODEL? Can you help us figure the thing out?

Thx,
D.K. Blanchard

1. It sounds as if your dealership has taken care of this issue. Is it resolved? 2. The SRS light is safety related and may have nothing to do with your performance problems. There is usually an SRS module that needs replacing in order to resolve this issue. 3. The hard shift and shudder could be transmission related or could be related to the ABS issue. The shudder could be the brakes being applied intermittently (pulsing) causing the car to shudder. If the ABS issue is not resolved I would get it taken care of before going further with this issue.
