Service Brakes Problems of BMW 525

I am encountering persistent issues with my 2005 BMW 525i. Despite having replaced several critical components, including the ignition coils, spark plugs, mass air flow sensor, and throttle body sensors, the vehicle continues to experience performance problems, specifically failing to advance beyond the fourth cylinder when driving uphill. After conducting numerous diagnostic tests, I have concluded that there may be an air leak in the intake manifold. Additionally, after prolonged use under these conditions, the positive battery cable from the trunk has shown signs of overheating, evidenced by smoke, which I suspect is related to repeated uphill driving. While the vehicle performs adequately on flat surfaces, it exhibits hesitation and jerking once it surpasses the fourth cylinder.

Brake booster is loosing vacuum when sitting over night causing the brake pedal to be rock hard at startup. The brakes are fine again as soon as the car starts. I know that the e65 from the same years has a recall on the brake booster vacuum line and check valve.

Brakes are not working (stalling) after fully stopping and reaplying brake at a lower speed. Brake padel is becoming very hard and even with all foot force brake padel is not being depressed. I had my kids in the car when this happened. I read it online similar problem accured in other BMW model and recall bulletin was issued. This issue is very serious and I'm willing to let investigators check my vehicle if they wish to check out the problem. Thank you iftikhar a. 7086126105.

When I realized a lightbulb in my headlights went out I bought the bulb online ready to replace it. I realized when replacing that the wires connecting to the headlights are completely flaked off. So I wanted money on a new bulb because it won't light up regardless. Now this not only causes the bulb to not work but it messes with the lights in the whole side of the headlight. My entire left headlight tweaks. Sometimes jus one parking light is out, then it's the high beam that doesn't work, then it's the low beam. Sometimes when I have low beams on the left headlight has its high beams on by itself. All this happened because I tried to change a bulb and the wirings jus flaked off as soon as they moved or bended a bit. This is very dangerous because my headlight won't work sometimes and that makes me not so visible at night. Also I end up unintentionally having my high beams on with no way for me to turn it off besides completely turning off my headlights. Pretty sure it's an electrical or fire hazard too to have a bunch of naked wires side by side. Fault number 2 is the brakes. When coming to complete stop my car jerks. There's nothing wrong with the brake system. I talked to a couple people with the same model car as me and they all had the same problem. It just happens once the car gets to a high number of miles. Something should be done about this because a functional car shouldn't be jerking when coming to a stop. Especially if the brakes are in perfect condition.

I experienced a rough idle while parked or stopped at light. Independent mechanic said there was a vac leak associated with the brake vac pump which could cause brake damage and/or failure. BMW stated that the recall for this problem was VIN specific. #2 passenger restraint and air bag lite are on, same answer from BMW.

I was traveling approximately 40 mph on a city causeway. I went to apply the brakes for a red light and had none. The pedal was very stiff and had no hydraulic assist.

I had no warning light or anything to alert me to the failure. I have since found out that BMW issued a recall for this very issue on the v8 engine but not for the i6 engine which I have.
