Engine And Engine Cooling Problems of BMW 740

Stopping without notice can cause an accident and any of the issues can cause safety issues. What I sent them. I am writing to express my concerns regarding a series of issues with my 2017 BMW 740i and to request your assistance in resolving these matters. I have been working with my local BMW dealership to address several problems, but I believe there may be underlying issues that require further attention. I would appreciate it if you could review my case and consider the points outlined below. Background: recently, my vehicle was brought in for service to replace the spark plugs and address a few concerns, including the replacement of the fuel tank cover. During this visit, it was discovered that the pressure control valve was faulty and needed replacement. I was not previously informed of any issues with the pressure valve, and I have learned that BMW has issued an extended warranty on this part due to known faults. My understanding is that a faulty pressure valve can cause erratic fuel pressure, leading to premature spark plug failure. Given that my car has only been driven about 8,000 miles annually and is used weekly, not sitting idle for long periods, the spark plugs should still have life left. However, they may have worn prematurely due to the pressure valve issue. Concerns: pressure control valve and spark plug failure: it is highly unusual for three spark plugs to fail simultaneously, as spark plugs generally wear out gradually over time. In most cases, one spark plug would fail before the others if there were a gradual wear issue. The simultaneous failure of three spark plugs suggests a potential underlying issue, such as a problem with the ignition system, electrical issues, or a direct result of a faulty pressure control valve. I request that BMW cover the replacement cost of the spark plugs under the extended warranty for the pressure valve, considering the potential causation between these issues. Hard jerk when.

Apparently BMW models like mine have been having the coolant expansion tanks leaking between 60 and 70 thousand miles. This causes the coolant levels to drop and causes engine failures.

Active air flap fault, upper and lower actuator is not working and that is why engine is overheating. BMW has extended this warranty to 10 years/120k miles for 750 and 550 series manufactured up to Aug 2019. But they have not done that on 740 series. My vehicle has the same problem and should be covered under the same in order to avoid engine damage. Please advice the next step. The fault code are: p05a0, p05ae, p05a2, p059f.

A chevy pickup pulled into the one way road leading to a hotel and immediately went around an ellipse and hit me as I was exiting my hotel and got hit in the drivers front quarter panel while he was pulling around in the elliptical one way drive. The engine was checked and it needs $5500 worth of mechanical work in order for it "to be safe to drive.

BMW e38 have a high tendency for the guides for the camshaft chain (s) to fracture and come apart. This leads to plastic pieces to cause catastrophic failure, plastic and metal shavings to be observed in the lower oil pan as well as jump in timing for the owner who has to either pay$$$ or junk the car. The should have at least utilized carbon fiber guides. Many of these failures occur even before 125k. . I find it incomprehensible that someone who pays 70k for this vehicle to have to endure spending another 5-6k to get the car running again. Just look at youtube. Com and you will see what I am referring to. Wish I'd bought a used Ford.
