I've got a 2003 E320 and yesterday the dash warning light at the speedo came out in bright red,

BRAKE Stopping distance effected or something like that.

Today I changed all 4 brakes sets, front and back and replaced al thee pad sensors. All came from the dealer parts dept here.

But the big red brake warning is still on.

Will the computer see all is OK in the brake system and turn off the warning after so many miles or will the warning light have to be reset by the dealer or service shop?

I trust the Mercedes dealer in town but I don't know the reputation of local shops.

I don't think brake pads were your problem. From your description the warning message sounds like the SBC unit (the brake by wire thing) has faulted. You'll need to go to either the dealer or a Mercedes specialist independent for repair. The SBC unit will need to be replaced. Expect the cost to be $1500-$2000.

SBC unit has a fault code. Get someone to read it and you will probably find the SBC unit has "timed out". Did you disconnect the module during the brake job?

No way that your parking brake is on, right? Probably not, since you already did the brakes.

Another case of throwing parts at a problem before finding out what the problem is. I would have read all codes FIRST then decided which way to go.

It was time to replace all 4 brakes sets. The rotors had just started to rub all three sensors. The hole for the sensor was open on the side of each brake pad, but I don't think the sensor detected the rotor yet.

SO it was time but I don't think that set off the warning light. But I did replace all three sensors, and all 4 sets of pads from the dealer.

I checked the Brake stop light switch with a ohm meter and it was still working too.

No I did not disconnect the module, what module? Please tell me more.

Would that have reset the brake light warning on the dash?

Brake wear and SBC failure are two distinctly different phenomenon. Disconnecting the SBC module is a safeguard against having the system wake up during brake service. If the SBC comes online it can exert enough pressure on the caliper to easily crush any fleshy digits in the way.

Try googling "Mercedes w211 sbc problem" and do some reading of the threads at peachparts and mbworld which come up as results.

Two hours ago I dropped off the E320 at Moss Mercedes in Lafayette Louisiana.

We expect the worst but hope for the best. The car only has 70K miles and otherwise in great condition.

I'll post when it's done.

I got the cause of the Red Warning light and the estimate from the MB dealer.

$1,550.00 total

The dealer found several other items they demmed needed fixing (Duh) but most are minor to me. I approved a few replacements of those.

The fault readings was a replacement of the brake fluid and the fluid container, hoses etc, and a defective brake light switch.
I checked the old switch with an OHM meter and it seemed OK to me, but I was just looking for a good short on the meter.

It was not the SBC unit, for now.

The car will be ready next week

You will KNOW when the SBC unit fails.

It'll be almost impossible to stop. You'll get the same red warning message and then your braking power will be drastically reduced.
