Good Day TDI Clubsters. A bit about me, I'm a 60yr old licensed mechanic/milwright. Drove mostly GM all my life. I've troubleshoot and resolved alot of issues, some highly technical and some downright silly. I recently bought a 2006 jetta tdi, in search of better fuel mileage. 400k and it runs great and unbelievable mileage. So here's the thing, my ps low beam drl bulb burned out recently and so I replaced it. Didn't work. (ds was fine) Too cold out to check the fuse so I packed it in for the day. Next morning I went to troubleshoot but now it was working fine and I didn't do anything. So, my question is , , W T F ? Anybody ever experience this before?
