Hi I'm new to the forum! Just a quick query regarding the 4th Service. I got a quote for a service as it's just turning 4 years old. The mymercedesservice website is coming up with the following: Service A £247.62 However, there are additional items which take the cost up to £928.72: Replace Brake Fluid £90.00 - I know this needs doing so I'm ok with this. Replace Air Filter element £140.28 Replace Fuel Filter £101.04 Automatic Transmission: Carry out oil and filter change with transmission 722.9 NAG 2 £349.78! Is the Automtaic Transmission oil and filter change, air and fuel filter change required? Or shall I just get the standard Service A and brake fluid change? Thanks in advance!
