Mercedes-Benz W211 Models are equipped with two batteries. The batteries in your w211 are an absorbed glass mat (AGM) type, which is different from the older style lead acid batteries. AGM batteries house the battery acid in glass mats. Lead acid batteries house the fluid between lead plates. AGM batteries are made of very thin glass fibers woven into a mat. This increases the surface area enough to hold sufficient electrolytes on the cells for their lifetime. Lead tends to absorb some of the acid, shortening battery life. There are positives and negatives when using AGM over lead acid batteries. For example, an AGM may charge faster, but is more susceptible to damage from overcharging. They produce less gas than a lead acid battery, can be mounted in any position (do not leak) and are safer for the environment because of this. One downside is the increased cost. Also, charging systems have evolved along with the battery type, allowing greater control of charging current via sensors and computer controlled adaptation.
The main battery in W211 models is located in the center of the trunk, mounted in a well, below the trunk carpet. The auxiliary battery is located in the right side of the engine compartment, near the HVAC intake. When replacing your battery, be sure to use a high quality unit. Replacing the battery can be done in a short amount of time. Read the battery connection notes before disconnecting the battery. Before disconnecting your battery, remove the key from the vehicle and store it in a safe place and note the radio presets. When the battery is reconnected or loses its charge, the following items may need attention (depending on vehicle equipment). You may have to reset your clock, enter the radio presets, initialize power windows, initialize the sunroof and normalize the steering angle sensor. See our tech article on battery replacing, for info on the main battery and jump-starting.
The auxiliary battery supplies power for a limited time if system charging or battery voltage drops. The battery control module monitors system voltage. If voltage reaches a low point, the auxiliary battery relay closes to connect the battery to the vehicle fuse blocks.
Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.
Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Have you tried both fobs? sounds to me like the button itself on the fob above the MBZ symbol for locking isn't working. You can take the key fob apart, and check the little buttons on the PCB / board itself for function. Sometimes they get stuck with dirt / grime to the point where the button itself under the plastic shell is not engaging.

You may be overfilling and allowing excess gas go into canisters sensor "smells" excess fuel. Always stop at first bowser click-off and proceed slowly.

Starter high up on back of motor/gearbox bell housing.
If motor cranks but not firing - sounds like fuel not starter.
Check fuel relays and if you have sufficient fuel pressure?

All the computers are needing to be reset. One thing to try is to start the car and then turn the steering wheel lock to lock several times. This sometimes rests everything. There are also several club sites online that have all kinds of assistance.

You are addressing the problem backwards. Plug a Scanner into the OBD2 port, read the codes, look up the codes and it will tell you how to fix the problem.

There may be some residue from the oil change, or something was left loose . It needs to be looked at. Return to the service center and have them take a look.
