Air filter housing lid screws corroded... any bright ideas how to remove please?

Managed to get the under tray off, various screws are missing, so will be needing a new batch to make good.

Got to the air filter housing and one of the screws is in a very bad way, no pozi left and the head won't take a socket.

Just wondered if anyone had had this issue before and could suggest a way round, thinking screw removers now, but never used it and it's a tight fit. Was hoping not to remove housing (if possible) or bumper.

It's the screw that's partially obscured by the bumper, so really need three hands! 😬

Never had much luck with screw removers especially in difficult to access areas, most successful I have found is mole grips if you can get a set on. Recently bought some Engineer grips pz-64/65 expensive but the did get the job done on a screw sheared off in brickwork, they have vertical jaw section to grip the screw head or whatever is left of the screw

Thanks, but I can't get grips round it, due to it being recessed. Can get needle nose pliers round it, but they are not strong enough to turn it.

So bloody frustrating, thought it was going to be a quick job o_O

I would try to drill it out at an angle - else take the housing off the car. Once the lid is off you should be able to get grips on the stub.
 
Remove the filter housing and you will have full access to the damaged bolt. Then your choice of repair existing housing by removing by whatever means and replacing the bolt or fit a whole replacement unit from @A2Steve
 
I did my airfilter today, and I thought about this thread.
Luckily mine came out and went back in, no problem.
I feel guilty now.
 
Steve's option is the optimum however you could drill the head and then remove lid and old filter and try to get the remnants out with some vise grips, failing that when mine sheared in I grooved the plastic to allow a cable tie to sit in a channel and pull the lid tight to the housing
