200 just for a bub is really too much for fog light in such cases you can approach the scrap yards i am very sure they may have them and they are far chaper. less then half.
Sure there is no issue at all. Actually on high speed it is good to have low stance. Only restriction is certain speed on highest most setting. But on lowest setting no restrictions.
Try ARM, Alex reinner they might help you sourcing one good used engine.
Alternatively try to source some guy in Shj Industrial area that deals in Porsche Half cuts (accidentals) and scraps.
Check the battery BIG fuse which is BOLTED usually. If during the first jump start or while changing the battery some short circuit might have happen. Then this fuse busted. Its a big AMP fuse.
Electrical issue are most difficult to catch, better concern qualiied porsche technician like ARM or Naboodah guys and let them diagnose the loose wire or connection.
