04 E55 AMG: Brake fluid flush
Posted: Thu Jul 30, 2020 12:43 pm
This needs to be done every 2 years. Also, it has the whole SBC thing so the brakes are extra complicated. As a result DIY bleeding/flushing is cumbersome at best and ineffective at worst. Not great. Also I recently had a thought that I could run into issues with that SBC warranty (should the need ever arise) if the failure can in any way be pegged to insufficient brake fluid maintenance. It would suck if I couldn't prove that I had flushed the brakes. Also, according to the records, the SBC pump was done in October 2014 along with the brake fluid (in classic German car form, about 3 months after he bought it). Granted mileage was only 118k so only 13k ago but as Mercedes correctly shows, it's really more a function of time not mileage. So if that's really true, it is quite overdue. I'm sure mine isn't the only one to have lax brake fluid changes but still doesn't seem ideal.
So with that, I'm going to do it myself.
Just kidding.
I called Mercedes-Benz of Warwick and they get like $185 all in for the job. They have the fancy computer and probably do this all the time. Plus, this will actually be logged in my service history. Other benefits include making sure Mercedes knows I own this car for any future recalls/campaigns. Speaking of, they'll also look at the sunroof recall which apparently actually takes an hour to determine if there is a bonding issue and if so I guess I would need a new sunroof? My car may not be effected which is fine and then they can close the open recall which is also good.
I'm going for the full experience so I am dropping it off Monday morning and getting a loaner.
I may get bold and actually ask what they think about fluid changes and the SBC warranty. They are a dealer so their answer would most likely be "service the car here, please" which doesn't tell me anything. I suppose the burden would be on Mercedes to prove that a future SBC failure was solely (or a heavy contributor) the fault of insufficient brake fluid changes. Then, I guess the burden would be on me to prove that it had been done. In a DIY setting I'm not sure what evidence would be good enough. Written records and brake fluid receipts?
At least as long as I have that SBC warranty (it's currently 25 years and I'd think that's the last extension, so I guess until 2029), I might make it a habit to have this done every 2 years...
EDIT: Warranty in service date is 4/21/04 so the coverage is through 4/21/29 (or 4/20? lol). I might not even have the car that long....but I digress.
Word is it may also improve general brake feel so I am curious about that. I think the brake feel is meh so that would be welcomed. It is a little amusing that computer controlled brakes have brake feel that is at all related to the mechanical/hydraulic system performance but I think it is linked. Besides, I wouldn't necessarily want the computer to hide an issue by making the pedal feel exactly the same even if there is air in the system and stuff like that.
OK that's enough on that - I will update after my drop off experience (and my loaner) and again on pickup, and then the road test. And any conversation of interest that occurs along the way. I will say the service receptionist was very patient and polite.
