2013 C250 Coupe
Service A7 and BG
Hi, my C250 Coupe was serviced last year with the oil, oil filter and spark plugs changed. Why would it be requesting a service A7, to change the spark plugs again? The second question I have is that I had to change the coolant pipes and the mechanic fitted the same gaskets (from the manifold intake) back as he advised that it wasn't hard or deformed. From online posts (google) many have said to change it to prevent damage to the engine. I'm not sure what to do. Then I also occasionally have a metal grinding sound near the rear tyres when driving up the driveway at home. I'm not sure what it is but have only had this issue after the dealership had opened the under of the car to check if the gearbox oil was leaking - this after the oil pipe under the bonnet had a crack and was changed. My mileage is around
