In E53 X5
Hello All, I have 2006 x5 4.4i that out of nowhere won't start. I was headed to take my dad to the hospital and we had 30 min to kill so we drove to a park and hung out for a sec. Went back to the car and ... doesn't start. Always happens like that! The car turns over(tick tick tick tick tick...) but doesn't start. While attempting to start, the temp gauge for the oil whips across the gauge and shows overheating. After a few goes, there is a smell of gasoline in the cabin. We haven't had any issues with the car up until this. We did do some preventative repairs in December replacing the left and right valve covers (which are plastic.. what the? ) , eccentric shaft sensor seal, crank shaft solenoid gasket and crankshaft adjuster o-ring. After these a fault code came up periodically saying that the thermostat is faulty. I had the shop look into this at the time and clear the codes and it was nothing at the time they said. The car is at a mechanics right now and they mentioned that they are still reading a fault code with the thermostat and a missfire on the 6th cylinder along with burning oil and rich exhaust. Any ideas what my issue is/ could possibly be? The shop is saying that we have damage to the cylinder head, due to overheating. I believe that it is a sensor issue. I can't help to feel like this shop(anyshop) is trying to bilk me of my hard earned moolah. Thoughts? Hopes? Prayers? Thanks!
