Hi there. Today's modern cars, trucks and SUV's are much more complex than older vehicles. As such, there really isn't a general "tune-up" service. Instead, manufacturers have created recommended maintenance service, which is unique for each make, model and year....

This is a problem in the garage a lot. You connect a battery and the alarm sets, then the car goes into lockdown and you can't start it. Sometimes it takes some experimenting. I would start by charging the battery...

Hi there. It really depends on what type of noise you are hearing that will determine what is causing the noise. If it's a constant ticking noise, it's possible your serpentine belt or the pulleys that drive that belt are...

Hello - there is an air bleed hose that runs across the top of the radiator (under a plastic cover) and into the expansion tank. There is a coolant level sensor, and a coolant transfer hose (expansion tank to the...

Hello - unfortunately, this is not a service YourMechanic.com can offer at this time. Thanks for thinking of us though!

Billing question sent to CS for the cost to replace the coolant hoses by the turbo and the engine oil pan gasket.

The first thing to do with a draw is to check and make sure nothing is on that can be turned on by a human. Some common sources are interior lights, exterior lights, after market stereo systems or other after...

As with most modern cars, things are more complicated than they seem. The BMW uses a lamp control module to power up the lights. It's not a simple switch-load connection anymore. Among other functions, the lamp control module senses malfunctions...

Your engine has gone into "limp" mode. The engine computer senses that one side (or the other) is performing inadequately, which causes it to shut down that side. This is most commonly caused by fuel pump(s) failing. The fuel pump...

Hi there, thanks for writing in about your 2006 BMW 750Li. The two causes of an engine to burn oil are faulty piston rings and faulty valve guides or seals. If the piston rings are faulty, this will allow oil...

This engine has eight cylinders with only one spark plug per cylinder. You have a total of eight spark plugs.

It takes "roughly" 8 hours but if you have the Xdrive version, add 2 hours. The cost depends on exactly what you want. A new transmission? A used transmission? A rebuilt transmission? The recommended approach is to install a rebuilt...

The calipers could have a piston that is sticking or the combination valve on the brake system is sticking causing the brakes to be locking up after touching the brake pedal. I recommend seeking out a professional, such as one...

Hi there. That is a very interesting situation you have with your BMW. To be honest, I've never seen tire valve stems cause any type of noise; especially under the conditions you're describing. It is possible that you may have...

Hello. From what you describe it would appear that your vehicle is experiencing some sort of electrical issues. If the Idrive system is not working properly then it may be possible that the Idrive computer has failed, or possibly the...

The 750 is a great car, but when it gets some age and miles it can become pretty high maintenance. There is no way I can tell you what is leaking from here at my desk, the car will have...

Hello. A fuel leak from underneath the vehicle is probably going to be caused by a faulty fuel line. I would carefully examine all the fuel lines that run underneath the vehicle, placing extra attention on the ones that run...

Your vehicle uses a high-pressure hydraulic brake booster. It's likely that the pressure regulator sensors that provide the braking assistance are not functioning correctly, providing too much "braking assistance". A professional mechanic, like YourMechanic, can assist with diagnosis of your...
