OBD-II diagnostic trouble codes do not and, indeed, cannot identify failed parts. Once you have a trouble code in hand, what you have to do is perform a diagnostic. In the course of that diagnostic individual parts are tested often...

Hi Marvin. Thanks for contacting us today. The main cause of over-torquing is using an impact or air wrench. However, the majority of damage occurs when the torqued component is in use, develops heat then cools. In your situation, catching...

Hi Imperia. Thanks for contacting us today. As fuel system components age and are continually used, they will begin to clog with carbon deposits from fuel. When this occurs, they essentially become like clogged arteries, and can lead to fuel...

The first thing I check for in any drivability problem is air leaks. Any air that gets into the engine without going through proper channels will lean out the system and cause these kinds of problems. Look under the hood...

Unless you could prove that the mechanic cracked the valve cover and it was not already cracked before they did the gasket. This would be hard to prove since it may take a few months for a leak to show...

This code relates to a fuel tank ventilation/purge system leak. Three years ago, BMW issued a Technical Service Bulletin - TSB (https://static.nhtsa.gov/odi/tsbs/2014/SB-10057341-3735.pdf) that documents a common cause of the code, namely a defective pressure switch. While other faults can cause...

If the pump has failed, depending on the failure mode of the pump, you can diagnose the fuel pump yourself. Turn the key to the ignition (run) position. At that instant, you should hear a momentary whirring noise from the...

The transmission shift points can be checked to see if the transmission is causing the jerking or it is caused by the brakes. A scanner can monitor the shift points to see if the transmission has sticking shift solenoids or...

Hello! A window losing operation can be the result of a failed window regulator and motor assembly. Have a mechanic inspect for electrical faults (https://www.yourmechanic.com/services/electric-problems-inspection) concerning the window first. Are both front headlights and tail lights not turning on? This...

Hi! The white smoke is a sign that the engines head gasket has blown and is leaking coolant into the combustion chamber. The coolant leaked into the hot combustion chamber then burns off in the form of white smoke exiting...

The noise you are describing is marked and thus the origin will be obvious to a mechanic on inspection. There may be evidence of direct impact for instance. Among the components closest to the ground are exhaust system components. The...

Hi Wendy. Thanks for contacting us tonight. After these repairs are completed, 80% of the time, this symptom is caused by the spark plug wires being connected to the wrong plugs, a vacuum line that is loose or an electrical...

You will need to have the cylinder number 6 compression tested to see if there is low compression in that cylinder? If it is low then have the cylinder pressure tested to see if the valves or piston rings are...

This could be serious. Driving a car while it is overheating can do a lot of damage to the engine. The cylinder walls need to be bathed in coolant at all times or the surfaces become so hot that the...

Hi Deshawnda. Thanks for contacting us today. Although some "mechanics" recommend using a liquid head gasket sealer, the truth is that 80% of the time - it doesn't completely do the job - or it causes additional problems. These sealers...

Well, if you've removed the belt and still get the noise, that eliminates most of the normal causes like alternators and idler pulleys. I doubt it has anything to do with the water in the cooling system although you absolutely...

Using the wrong coolant shouldn't have any short-term effects like that. The consequences of using the wrong coolant usually relate to seal and head gasket failures over a long period and if you have replaced it, everything should be fine....

This is most likely the result of a clogged windshield wiper nozzle (https://www.yourmechanic.com/services/clean-windshield-washer-tubes-and-jets-inspection). Try blowing compressed air through the nozzle or cleaning the head of the nozzle out with a pin. Try tracing the washer hose from the nozzles back...

Hello, thanks for writing in. I'd be happy to help. White smoke from the exhaust can be caused by a few things. First off, keep in mind that white smoke coming from the tailpipe after a cold start can be...

The front wheel bearings would need to be replaced with the front hub assembly unless you have the very specialized puller and press tools to remove and install the bearings. It is recommended to replace hub and bearing as an...
