If the Battery Light is illuminated and the battery passes a load test, then you most likely have a faulty alternator; a charging system test would need to be performed to verify this. On the 2001 540i, the power steering...

The battery should be load tested by a professional. Load testing can only be reliably performed on a fully charged battery. If the battery passes a load test be sure it is NOT a marginal pass in which case you...

An easy way to isolate if the ignition coil is the problem is to swap the #8 coil with another cylinder. Swap the #8 coil with the coil from the adjacent cylinder, then clear the codes. If the code remains...

Hello, thank you for writing in. Your guess that the heater core is to blame is very likely correct. Not only are they common components to form leaks, but it is also the component located in that area. It would...

The transmission control module has various sensors such as vehicle speed sensors, wheel speed sensors, throttle position sensors, turbine speed sensor, and transmission fluid temperature sensors that all direct information to it in order for it to perform it’s function....

Hello. I suspect this accident damaged a wheel or tire, which is causing the vibration you are experiencing. Bent wheels or a damaged tire which has tread separation are the likely problem. If you jack up the car, carefully blocking...

Hi there. This sounds like a case of a failed alternator & battery duet. Many times these can fail within close time frames of each other and are usually recommended to be replaced together so that it has a new...

With the vehicle overheating I would advise caution as overheating the vehicle can cause extensive damage if left unchecked. A stuck closed thermostat along with coolant leaks are among the most common causes of overheating. A qualified technician, such as...

Most of the time, cold weather starting issues are caused by low cranking amps in the battery. However, if you're able to crank it over rather easily, you may have a throttle body that needs to be cleaned. Sometimes fuel...

The Advancetrac is the name for your traction control system that is used by Ford. The traction control system monitors the steering stability of the vehicle and engages when loss of traction has been detected. This is done by the...

I would recommend first making sure that an exhaust heat shield is not the issue. This can be done by having a professional get under your vehicle and check for any loose parts on your exhaust system. Replace any faulty...

Hello. The code P0108 means the manifold absolute pressure (MAP) circuit is detecting a high input voltage. The PCM and MAP sensor communicate through a 5 volt wire that changes voltages as the sensor's reading changes. When the sensor detects...

Hello - the required maintenance depends on which problem code is setting off the Check Engine light, and what the other symptoms are. A throttle position sensor failure will cause different behavior (and set different codes) than will a dirty...

If the car is burning oil, you may notice a bi of blue smoke coming from the exhaust. Blue smoke coming from your exhaust generally means that the motor is burning the engine oil. This can happen for a couple...

This may be related to a faulty throttle position sensor or potentially a dirty or failing mass air flow sensor. The mass air flow sensor monitors air intake as it is mixed with fuel prior to being injected into the...

Low voltage is one of the main causes for a starter solenoid to click continuously without turning the engine over. An electromagnet pulls the contacts together in the solenoid. As soon as contact is made and the starter motor is...

What you are describing is a sign of warped brake rotors. When you press on your brake pedal, this activates a hydraulic pressure which forces small pistons inside your brake calipers to push the brake pads against the brake rotors...

There is nothing that an owner of a 2009 Chevy Traverse, or most GM vehicles from 2007 thru 2011 that are equipped with this design power steering pumps/Rack and Pinions, can do to prevent these failures. Chevrolet has known about...

Hello there. Many faults could cause your vehicle to consume excessive fuel. The most common faults are a misfire condition, a bad mass airflow (MAF) sensor, a fuel leak, a vacuum leak, a faulty oxygen sensor, or an exhaust leak....

The GMC Yukon 1995 came with 2 different motors and the 5.7 was the most common. The most common problems with this vehicle from most to least common are: the fuel pump and filter, starter motor, ignition module, crankshaft position...

When a sensor is detecting one of the wheels stopping, it will cause the brake pedal to bounce and the vehicle will stop differently than normal. The bad sensor may be causing a bad signal to the ABS module telling...

If your vehicle has ABS brakes, it is possible that there is an air bubble in the ABS system. Many vehicles require a special bleeding procedure for vehicles with ABS. This will require you to do the bleeding in a...

Your car’s message center (if equipped) is “information central” for a wide range of different things. It can show information about tire pressure, about doors that aren’t closed and a great deal more. Of course, there are a few things...

If it's running rich, it can easily flood the engine out and cause it to burn oil. So I would work on that first. But that said, realize that the only thing you are testing the engine compression is the...
