Having changed the 15 year old starter and aux batteries in my W164 ML500 I now have a couple of error codes. I don't have an OBDII reader / diagnostic tool but will be getting one shortly - Autel MaxiLink ML629 OBD2 Scanner Upgraded Version of ML619, DTC Lookup, Ready Test, ABS/SRS/Engine/Transmission Diagnoses: Amazon.co.uk: Car & Motorbike
(unless anyone convinces me otherwise)
I was getting spurious error codes as previously detailed which led me to changing the battery. (ABS/ESP/lights/tyre pressure sensors).
The current error codes are mostly the same, plus a reference to SRS. I believe this is possibly due to disconnecting the battery generating a fault.
Is it possible that stored faults can cause the vehicle to go into limp mode ? - I'm assuming it's limp mode (never experienced it before) as it won't change to higher gears so end up maxing out at 60mph @ 4krpm
Or, does this mean that the actual error condition is still there despite having swapped the battery?.
This is why I'm thinking of getting the OBDII tool, clear the fault codes and see if they come back, as in a genuine current fault or see if it clears the limp mode and generally makes everything better - at the worst/best I get a better view of what's occurring .....
