Stupid ways you've damaged your W203 while working on it




Please keep all posts relevant to DIY work (direct or indirect). No backing into a wall etc.
I'll start. Broke a coolant hose connector when leaning over to fix my vaccum pump (famous M271 leak). Sprayed coolant all over the engine and ground. Thank goodness I had a spare one lying around, and extra coolant!
Another time, I rounded a caliper bolt due to using cheap/crappy tools. Had to pay a mechanic to drill it out.

Also over-torqued the stretch bolts (x10) in the cylinder head. Broke one off and had to drill it out + replace them all. Sigh.

Also! Broke an exhaust header stud off right in the block


Also!
Broke a bolt that holds down the cam 'tray'

and later ran my fingers over with a parked car :-\

Once accidentally lowered an open back door onto a jack stand (side of car was in the air only held by the open door (don't know how it didn't bed anything)
While changing belt tensioner my dad and I had a torque wrench seize up and never clicked and broke the bolt off in the timing case cover. (had to drill out and use helicoil to fix)
Took out ac controls and broke ribbon cable to all steeper motors on accident and had to super glue connector back together the cable is cheap but the insulation would have killed me.
Put too much weight in glove box and the catch broke and now I have to hold glove box when it is open or it fall off.
I probably have more but that is all I can think of at the moment

That's my first mistake on this Benz so there's not so much benz action going on (yet
)I've owned an '07 Fiat Palio before, only managed to forget a wrench under the hood, drove with it for a long time until it decided to fall onto the belts and pulled one of them off the pulley, had to buy a new one (just in case).
I've also owned a '69 Beetle, just dropped it of the jack, ofcourse nothing happened to it, the asphalt was hurt a bit though

leaned on the engine and broke the plastic hose connector for the rad and hence my post https://mbworld.org/forums/c-class-w...ance-item.html
Shattered the engine cover while trying to remove it to change the spark plugs as the locator pins in the front were stuck. I epoxied (tinted) and fiberglassed it back together underneath and you can only see a faint line with a very bright light see post https://mbworld.org/forums/c-class-w...ngine-bay.html

Snapped a RAD lug bolt when changing over to summer tires, tried all sorts of ways of getting the rest of the bolt out and finally had to succumb to the dealer and they tried every method and the only fix was a new hub and bearings ~$600 incl labour

and finally almost damaged myself almost 30yrs ago when my Renault 5 came down the ramps with me still under the car, my chest got compressed by 2" and turned my head at the right moment and still here to talk about it

Add another 2 to the list
- nicked the rocker panel with the screw part of the jack when I didn't position the jack correctly and tried to raise the car.
- rubbed some of the reflector silver off one of the fog lights trying to wash some fingerprints off.
Obviously there's no way to fix this, so I painted those plastic pieces flat black instead. You wouldn't know by looking at the lights unless I pointed it out.
