'99 ML 430 new battery install & BAS/ESP light
 

51,000 miles. Orig battery died REALLY suddenly and REALLY dead - would not crank even jumped from towtruck. Took dead battery out, had it checked at Kragen (parts store). Bought new replacement battery, drove back to ML430, and installed. (Car was without battery for maybe 1 hour.) Car now starts as usual, but BAS/ESP warning light is now on (and stays on) and once I press gas pedal the motor keeps searching for an idle speed. Also gas pedal seems ineffective. I could idle the car to a dealership, on surface streets. Owners Manual is missing, so I'm at a loss re the meaning of this warning light. My guess is that something(s) need to be reset after having been without power??

response on other thread

i responded above

For those interested - carson 356's solution (worked like a charm!!) is this: 1.) turn on engine and rotate steering wheel lock-to-lock several times; 2.) turn ignition OFF; 3.) turn ignition to ACCESSORY (engine OFF); 4.) wait 5 minutes; 5.) start engine. I did all of the above ONE time and ML430 runs like it should. (I thought I should leave a follow up here since I posted at 2 areas - and I noticed plenty of viewing)

Same problem
 

Guys, I seem to have the same problem. My ML430 battery died, replaced battery, now car starts first time but wont drive at anything more than idle speed plus my bas/esp light is own. tried every reset mentioned on this forum plus others and it wont work. Any other ideas?

My car is doing that too but the thing is the battery light is still on even tho i put the new battery in and the next morning my bas abs esp and srs and battery light was all on?!?!?!?!?!?
whats that suppose to mean

What to do to reset things after dead/removed battery is included in owners manual.

Throttle relearn procedure needs carrying out. ESP/BAS prolly needs code/s cleared for ''Low Battery or '' + Short To Ground.'...... common code when battery goes flat.

If you don't have a scanner..Launch or SDS, try leaving engine running for 20 minutes at idle and then turn engine off. Restart and check throttle action.

I did get one to relearn by just turning on ignition, and off again after 1 minute.

ESP/BAS likely needs Steering Angle Relearn procedure...turn steering lock to lock with engine at idle, turn off ignition and restart after 10 minutes.
