my w203 has a couple of errors when we ran star diagnosis with it (the car is brandnew, stored for one year, and has been shipped for about 30days from europe to asia). i dont seem to notice any unusual things on the car though, except that my keys cannot lock/unlock the car using radio frequency. only the infrared system works. now my dilemma is that, i already brought my car to a remote island where star diagnosis is unavailable. one MB mech who happened to have been working on the mainland is offering to fix my car by erasing all "errors" by "removing the car's battery" for about an hour........is this solution possible???? he is saying that by doing so, my keyless entry could work again..... Any ideas from MB techs out there??????? Thanks!
