Caring for a Higher mileage C43
2018 Facelift and absolutely in love after coming from S3 and then Golf R ownership.
Its at 54k (miles) and wondered what others do to keep higher mileage C43’s happy.
Its had correct services done and the transmission service so thats sorted.
Ive always done oil and filter changes between services and only ever fill with Shell V power (99Ron) on all cars so will maintain that, but wondered if there are other regular or irregular maintenance bits you guys do to really keep the car ticking along.
Plan is to keep it for 3/4 years to 90k miles.
Cheers!

Don't forget the transfer case and front and rear diff fluids.

Next on list is the cam shaft magnets and the sacrificial pig tails, struggling to find the parts in the UK though so hoping my local indi can do it.




Oh, by the way, I WANT YOUR CAR!!! I would love to have a C43 wagon, not sold here in USA, and that is the perfect color. Great choice! Keep up the maintenance. Not that maintenance prevents all breakdowns. Example: watch for leaky dynamic engine mounts as they are VERY expensive to replace. Lots of labor to drop front subframe on an AWD car.

Cant believe they dont sell em over there rapid soccer mom vibes, its the only C43 or AMG ive seen in that colour which i like, love then motor. Enjoying it.
I took it to an Indy for the diff work so they did both on request.
Going in for a check on cam shaft parts for oil wicking next week and a replacement of the magnets, solenoid and sensors if so. Fingers crossed.
Appreciate the heads up on engine mounts. Is it just luck of the draw then?
