JCLS55AMG

Hey guys I am taking my Cls55 AMG in for an oil change with engine oil filter change.

What other fluids should be done?

Transmission oil fluid and transmission filter?

Differential fluid also?

supercharger oil?

As for preventive maintenance. What should be done as a must?

Have you got the 010 intercooler pump in? If not I would replace. You can find plenty if them online for cheap let me know if u need help finding one. When were spark plugs done lsst? Transmission needs to be done every 60000 km so maybe that is due too. It's good to stay on top of oil intransmission like in engine.

I have the renntech stage 1 tune witch came with there intercooler pump, ecu tune and SC pulley.

Should I request a full transmission fluid flush or just drain and replace transmission fluid?

I have no idea wen spark plugs were done.

Okay then yeah you might want new plugs. Is the idle silky smooth or a bit rough? Since you're modded you can go one step colder ngk reccomend going one step colder when power increased 75 to 100hp. Here is a link to a good deal on the plugs you want.

Yeah if trans not been done in 40 to 60 thousand kilometers I'd ask them to flush it.

Brake fluid every 2 years, and you should really know the condition of your supercharger. the oil in the front goes away over the years, and the bearings in the back tend to lose their grease then get loose after 10 years or so. There is good info on all of this if you search the 211 amg forum.

Make sure the spark plugs are authentic when buying online! There is alot of fake denso, ngk and others online.

Need to buy them from a reputable online source. Ebay has alot of fakes. You would need to check the part really well for authenticity.
