Well, Just got my Service B today. They say I have a seal leak that requires the axls to be dropped $700.00, rear brakes and rotors and fluid change $600, Service B $400 and they are saying I need to change the air filter, spark plugs. They are saying that codes are coming up on my transmission but the visisual inspection did not show any metal. They said that something that helps the transmission communicate during driving is going bad and needs to be changed. They said this was why I am feeling hesitation when accelerating at times. First thing. Are spark plugs DIY? Can I do this myself or does it have to been done by prof?

Thanks

Yes, plugs are DIY. Do a search. Takes about 1 to 2.5 hours depending on your handiness.

Thanks Newton,
Did a search and I see alot of threads on DIY plugs. None for S430. Do you change yours? Could you give me the steps? This would be a tremendous favor. Thanks for considering.

The S500 and S430 are the same as far as plug changing

lorinserSclass

oh yea air filter change is super easy...do a search..thats how I learned...took only 5 mins to do

It's the same for just about all newer Mercedes V8s. Keep in mind we have 16 plugs. Any thread depicting swapping the plugs out on a newer Mercedes should apply to the S-class aswell. PM if you need any help.

I still have my 16 Denso plugs in my trunk... have not found the time to change them yet... so one said it's impossible to get to all of them without removing stuff from the engine compartment.

Are Denso good plugs? I see them available at autozone and advanced auto.

The general concensus says that the Denso IK16's are "da bomb"...

Literally. They're hot plugs. Anyone tried running IK20s in the M113?
