Whatever penetrating oil you use, you have to shock those bolts with 
large hammer and solid rod, some time several times before been able to 
unscrew them. Same goes for any other allen key type screw on the car. 
Otherwise, the key slot is rounded and the torch or drill is the only 
answer. Penetrating oil helps significantly, especially after the first 
shock treatment. Next time change those bolts with standard head or 
torx, as used on some VAG cars, and always renew them in any case.

HTH and regards,
