He seems professional. I paid for the lights to be addressed and they are all still on including a low engine oil light. He said he would return to check it out further after his next appointment but I did not hear back from him. I was told by BMW that the power steering fluid needs to be drained, flushed and refilled. He sucked it out with a hose twice and this will not ensure that the oil that was accidentally placed in there would be completely removed. I am no mechanic but I am going off of what BMW told me. I wanted to get a lot more work done. I want all the lights to be addressed and fixed so I started with the check engine lights to be looked at and not just reset. I want everything to be fixed. Thank you

Pete was great! I got an oil change and tire rotation on my BMW 328i. Pete arrived a few minutes early, worked fast, and was friendly. He even helped me out by providing me the service engine warning light codes since he needed to clear my oil change light anyways. I'd highly recommend Pete!

I thought David was great. He was very courteous and professional. He did a pre-used car inspection for me on May 7, 2016. However, I filled the vehicle with gas yesterday and it has serious gas leak. So this is an aspect of his inspection that he missed. Again, I thought he was very professional and would recommend him. But any such inspections in the future should include the gas tank.

All about Drive Belt Tensioner Replacement

A Drive Belt Tensioner is a pulley mounted to either a spring mechanism or to an adjustable pivot point that is used to keep constant tension on your serpentine belt. That is the big long belt in the front of your engine. The tensioner rides on the outside surface of the belt to put pressure, or tension, on the belt and against the pulleys that drive things like the alternator, power steering, air conditioner, etc.
