This could be the fuel injection system or something could be loose in the engine like an engine mount. It is dangerous to have this situation so it might be best to take it to a mechanic.
Actually not all E class 9r especially E320 like mine has a fuel pump relay in the fuse box under rear passenger side seat. Mine actually is part of the K40 fuse/relay box under passenger side of hood near the firewall
you must replace a sensor that is located on top of the bell housing unit . you must stick your hand between the fire wall and the engine. this is nothing but a magnet that detects the #1 piston in your engine. it costs around $120.00 if you do it yourself you will be saving around $400.00 in labor. I think it's called a cranking sensor good luck
What would cause my VW golf to cut out whist driving
If you mean 'cut off' as in the car dies while driving its probably your alternator.
On my 1998 E320 the glass had cracked or something and the light differentiating fluid had leaked out leaving me with two images. The dealer wanted $450 for the mirror. I carefully cut out a piece of cardboard the size I wanted and had a local glass shop cut a mirror. I attached it with double stick white cushy tape and caulking onto the existing mirror. Cost $20.
why does it matter if you're driving down a hill? At least it didn't cut off when you were driving up a hill? And I don't know why it would cut off I'm 13.
Several things can cause your car to cut off while driving. Run a computer check for possible bad codes to see what may show up as a cause.
yes
No spark .no fuel.

main fuel relay going bad. Eventually car will cut off while driving.
