    If her Mercedes is like my BMW, there may be a sub-frame under the cast aluminum oil pan and a power steering rack. German engineers like to make things too complicated.

    If the steering rack is in the way, you can leave the steering rack assembly in one piece (not disconnecting the ends) and just remove bolts to let it flop down loose on to your chest and you won't have to pay for a new front-end alignment.

    Before the sub-frame can come out, you have to support the full engine weight from the top with a hoist or a truss that goes across from fender to fender. My BMW sub-frame was held in with 9mm metric fine thread self-tapping bolts. Replace those with new ones to be sure that the bolts hold factory torque.

    2015 oil pan may be hard to find used. Pay for the real Mercedes OEM gasket set.

        That might need replacing of pan
        IMO
        That’s definitely a hole not a crack

          I hope she didn't drive it very far with a hole that size

          If so I would be ready to spend some money

              Goggle Belzona Molecular Metal. I have used it before on holes in both steel and aluminum. If used properly it is almost miracle like in performance. The product is expensive because it comes in larger sizes mainly for industrial usage. Per oz it not that expensive, but most people shy away because of the size of containers. It will keep for years, if stored properly. Any product tough enough to be machined is very good. You may have to search around for it, but industrial supply houses are good sources for it

                  Not sure why they leave these aluminum oil pans so exposed.

                    Looks to me like a good man with a tig could fix that in place.

                      Have it towed to a shop and get it fixed right. If it's expensive, file an insurance claim... County or city may be liable if the pot hole was on a public street.

                      I would never have my wife drive a car with our kids hoping jb weld is going to hold up...

I am out of town and told her not to drive the car with a baby in it. What do you recommend I have somebody due being cost efficient..

                        Tell her to not drive the car even if the baby is not on board! She will really have an expensive repair job then.

                        When the baby is in the car be sure she puts the BABY ON BOARD sign in the window.

                          This quote above. I hope you find the broken piece, im willing to bet it is still inside. Maybe flush some more oil thru it and hope it falls out.

                                Road Hazard. Call insurance.
