i asked them to do an oil change, which costs twice what i pay elsewhere but I thought well its overdue so i might as well kill 2 birds with one stone.

Now they say there is an oil leak that has contaminated the engine module and is causing a short that is causing the engine light to come on. But they can't find the leak. Ive never seen any oil whatsoever on the floor under the car in the 4 years ive had it. I bet they spilt some during the oil change.

I only put in the dealers because its due an emissions test and the EML light being on is a fail even if there are no codes.
