Strange (Hydraulic-like) buzz/ vibration when the vehicle is coming to rest @ ~5mph

I just got an 06 E350 pewter 4matic, prod date 02/05... I have some questions:

1) My tire size is 225 over 16"s. I've seen E350s with 17" over 245 (non-sport packs) ? Is this an option for me ? Just want to make sure there's enough clearance for 245

2) When the car is coming to rest and the foot is on the brake pedal, for good 3 secs I feel a bee-like buzz (seems some sort of a hydraulic function -either in the transmission or Brake Master Cylinder.. just guessing), you can feel the vibration in your foot as well .... and then after abt 3 secs its gone ... This also happens when the Reverse is engaged .... Is this normal ? does anyone experience this ?

3) My service D+ is due, would the dealer run all recalls automatically ? Is there anything in particular that I need to ask him to do ?

Thanks Folks!

1) don't count on me but I don't see why those wheels would not fit to this car, I assume those are standard on some 4-Matics, if not wider tyres.

2) SBC pump.

3) They should, and there should not be any recall pending but I would still remind them and specifically ask them to check this.

Question

I also recently purchased a 2006 E350 and have this problem at slow speed - is this vibration normal?

06 E500 sport
I tried out my neighbors Dunlop Azzera (245/45/17) tires/wheels on my E500.
I thought my steering pump was going out it was so loud.
Put my stock staggered wheels/tires on and all was back to normal.

Could be some tire noise like I felt, too.

I have the same issue when coming to a stop and my noise starts around 10mph-0mph and when I come to a stop I hear a 'pssssh' like something is relieving pressure? I'm bringing it to the dealer Friday so we'll see.

2. SBC Pump. Have the dealer inspect if the recall was performed on this.

Recall Campaign 2005070007 APR06
Inspect SBC hydraulic unit, replace as directed
E / SL (2004)

Recall Campaign 2005110001 APR06
Installation of ground wires and bracket to SBC wiring harness
E (2003-2006) / CLS (2006) / SL (2003-2005)

Recall Campaign 2004050014 OCT04
Programming SBC hydraulic unit
E / SL (2003-2005)

Netstar message “Extended Limited Warranty on SBC Hydraulic Units” dated 5/5/06 now provides coverage for 10 years / unlimited mileage. Recall campaigns 2005110001 & 2005070007 have both been revised accordingly.

MBUSA DTB P-B-42.46/27c DEC03 - Buzzing noise during pressure buildup from SBC system. They should install a pulsation damper. The noise will not be eliminated completely however, it should be reduced substantially. Copy forwarded.

Thankyou all.

I took the car in and the dealer showed me VMI which had all Recalls taken care of (atleast on the paper)

Next thing I'm worried about is: Depreciation!! I'm seeing 06s E350s for low $20s under 40k miles ..... after a year 06s wont sell for over $15k!!! thats horrible..

Anyway, my 4matic is giving 25 mpg on the highway, Is that a norm ? I'd say to hell with snow, 7 speed would atleast give 28~ 29 ... plus who drives a Benz in a blizzard ?! thoughts??
