A210 servicing intervals?

[CharleyNokia]

Hi guys, I've finally got my A210 back from the garage after some work doing for the RWC. I was wondering what this service A and B are. what mileages are these at? I ask because the car has no history, and I've just had the garage change the oil and filter, air filter, fuel filter and coolant. what about the serpentine belt/drive belt/s? Also, should I get the timing chain tensioner changed too?

The ESS website will e a good start - put the vehicle details into the search boxes here:
Mercedes-Benz ESS

Best if you can buy a replacement service book as that will have the detail of what's required and when.
