Re: auto box changing to soon
Have to have a Merc reader. Just checked on one machine that had no warning lights and Torque Pro found nothing but a Merc reader found 30 separate issues in history. Crossie is really a facelift SLK320 under the skin and has the same computers.
Trouble is that replacing the battery trigger some "low voltage" faults so the Merc advice is to read all codes, save them, then clear them, and see what comes back.
