Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Did all of the other lights remain off besides this one?
Thank you. If the oil light is now coming on and if they have checked the oil pressure with a manual gauge then you may have a faulty oil pump or an issue with the valve lifters. Most of the time thought this it caused by a bad sensor. Did they verify this with a manual gauge or did they just scan the computer?
I am not sure which state you live in but most areas have protection against things like this. There is no way that you should be paying for anything unless it fixes it, unless they are asking you if you okay the repair knowing that it may not fix it. There are only a few things that can cause this, but they should be able to pull the oil pan and inspect and test these parts to see what it is. It may be the oil pump or it can be the variable timing lifters.
