No, timing chains can outlast the life of the car. Only a problem if it starts making noise from getting too much slack, or jumping timing.
But that will probably be after the next 100,000, or more.

Too many causes. The best way to know what causes the check engine light to turn on would be to connect the diagnostic tool and read the codes. If you are new to this, take your car to any professional mechanic, and he will diagnose your vehicle for free mostly.

No the ML 350 uses a timing chain and the water pump is external on the front side of the engine. No timing belts to worry about on those engines.

This car uses a timing chain and that means unkless there is a problem with it it is not replaced, it is n0ot like a timing belt.

The gas cap or the gas cover?

If the cap wont go back on then I don't know whats going on there.

If you mean the COVER or fuel door, then I would say your cable release is gummed up and sticking. Get some WD and spray the latching point on the car and then push the door in and let it spring back a couple times..spray again and repeat.....do this until the door stays shut. Then the next time you are getting an oil change get the station mechanic to spray the latch with some white lithium or other approved lubricant.

good luck and be careful.

sounds like piston has failed in caliper. cost is equal rebuild or replace,i think you would want to replace.
