Hi, I own a cls 63 amg 2006 plate and I was wondering about service intervals. It still has over 4000 miles to next service on the ASSYST but was serviced this time last year. I'm not sure whether to go off time or mileage as I know the modern mercedes' ASSYST claims a fixed mileage or time interval (whatever comes first) opposed to the ASSYST that is installed on the less modern car which only claims a mileage figure. Any help will be greatly appreciated. Thanks.
