BMW 740iL Oil/Fluid Leak Inspection at your home or office.

Common reasons for this to happen:

Now that you know, or at least suspect, what is leaking from your vehicle, you have an indication as to what may be wrong. This allows you to estimate the severity of the problem.

Here are some potential issues based on the type of liquid that is leaking:

• Windshield wiper fluid: Your vehicle may have a hole or crack in the fluid reservoir or system-related tubing.

• AC condensation: If you’ve run your air conditioner for any length of time, it’s not unusual for a little clear condensation to escape your A/C system. In this case, it’s likely there is no problem at all, and you can go about business as usual.

• Brake fluid: Although it is relatively easy to confuse older brake fluid with motor oil, a brake fluid leak is not an issue to take lightly. Brake fluid maintains the hydraulic pressure in your brake system, and without it, brake failure is a high possibility. If you suspect the liquid beneath your vehicle (usually around the wheels or just under where the brake pedal is situated) is brake fluid, call a mechanic. Do not take the risk of driving.

• Motor oil: Oil leaks at the front of your vehicle can be indicative of a wide range of problems. These include a worn gasket, corroded oil line, improperly attached oil filter, or a stripped or leaky drain plug. Before driving further, be sure to verify the oil level in your vehicle is not dangerously low.

• Antifreeze/coolant: Cars manufactured prior to fuel injection used coolant containing silicates to help seal small leaks. Modern cars cannot use silicates, so even minute pores can allow small amounts of coolant to leak. If, however, the leak is more severe, it could indicate a faulty water pump, loose clamp, damaged hose, or worn O-ring. Since antifreeze is poisonous to pets and local wildlife, such leaks always merit a call to a mechanic.

• Gear lubricant: This type of leak – often on or near the wheels – suggests a worn seal or that it is time to service the gearbox.

• Power steering fluid: If your power steering fluid leaks around the front of your vehicle, it is indicative of a faulty fluid line or worn seal. This type of leak is typically accompanied by a high pitch whine.

• Transmission fluid: When this fluid escapes, usually around the center of your vehicle, it may be indicative of a leaking gasket, seal, or cooler line. Some modern transmissions do not have dipsticks to verify fluid levels, so if you suspect a transmission fluid leak, it is best to have the vehicle serviced as soon as possible to avoid further damage.
