How has this happened?

[CycleSi]

Bought a SL55 AMG (2004) from a MB dealer last November.

The car 'told me' it was 5000 miles until the next service - less than 4 months on and 1800 miles later, it has gone from last week saying 3800 miles until the next service to today when it says a service is due in 29 days !!!

Despite it being a SL55, it isn't driven that hard so why does it suddenly think it almost needs a service especially when l figured l had a year's motoring ahead of me before the next service.

ls this normal or should l be taking it up with MB?

Not happy.....

very normal, it reverts to a time based system if you do low mileage.
dont worry,

How do l set it so it only needs servicing every 1 to 1.5 years?

I dont think you can, its based on preset parameters and/or information from sensors around the car.... so suck it up and let MB rape you for changing the oil and calling it a full service...!

it's set to two years anyway, if it only came on after 4 months and the dealer told you he serviced it he lied.
