If there is a leak, you will usually see a buildup of oil underneath. N54 Valve Cover Oil Leak Replacement There are one of two scenarios here: you could have a simple leak from a worn down gasket, or you could have a cracked valve cover that it causing the leaking. Some people panic at the first sign of any irregularity. I went to the dealer and was told that this happens all the time, simply due to how hot and dry this model gets under the hood and the headlights being sealed. That is excellent that those repair jobs were previously performed. The affected vehicles may have been programmed with new software that inadvertently makes the front side marker lights inoperative in conjunction with the parking lights or the headlights.
It broke and the timing chain chewed it up and sucked belt bits into the engine. Only under extreme conditions during racing is that a problem. This leads to a buildup of carbon deposits inside the valves and ports. Hazard: Should the system fail, in the event of a crash, the front passenger air bag would be deactivated, increasing the risk of personal injury. He also stated the car had no visible signs of damage, to undercarriage that would suggest any damage.
They said it's usually covered by the extended warranty, however not in the case of my vehicle's mileage. Road tested and no boost leak, but still a little rough idle and some stuttering when maxing the throttle. Oil-coolers, over-heating etc etc Are their still problems for 2008 models of the 335i? Even at its entry level, the 3 Series package provides an engaging mix of character, quality and performance. The approximate failure mileage was 69,138. These headlights have a mechanism in them that control the movement and it breaks quite often especially on bumpy roads. The N54 water pumps typically fail around 70k-80k miles. While traveling at a high rate of speed, the vehicle made a noise, sputtered, and decelerated.
If you chose to, just know you have been warned. Hazard: If the fuel pump fails, the vehicle may stall without warning, increasing the risk of a crash. This primary failure could cause adjacent components on the fan assembly motor circuit board to overheat and short. Fortunately, there are some useful preventative measures that can be taken to reduce the likelihood of leaky fuel injectors. Only under extreme conditions during racing is that a problem. No one had to get 'new' oil coolers; some models were not equipped with them, and some of those owners felt that they needed them, even though they had not experienced any overheating problems. Its tough to place an exact number on it as there are certainly many instances of these parts failing prior to that 60,000 number while there are also plenty of examples of those parts lasting well longer.
They gave me what I wanted for my trade-in and will hold this car until I can return to make the trade in 1-2 weeks. Per my message above, I had an error code for a boost leak. N54 Carbon Build-up If you read our fuel injectors section above, we touched on natural carbon buildup inside the N54 engines and how it can lead to problems with the injectors. Over time, the high current flow and heat from electrical resistance may lead to a breakage of the connection, and a loss of electrical power to the vehicle. Not just the power supply insulation on the wires for the ballast was chipping, all of it was chipping.
It's not a delay which decreases a transient surge. So yes, I would say that the 2009 335 looks like a very reliable car. By this time, I noticed smoke coming out of my headlight mount. The manufacturer was not made aware of the failure. This is jammed so far up that it lights the roof in my garage and I can't see anything on the road in front of me. Thank you for the comment, Sdub.
The approximate failure mileage was 78,000. The water pump is responsible for pumping water into the radiator, in order to cool engine temperatures. It increases the transient surge as the car does not respond to the throttle for a half second then bolts forward with an awkward lurch and a slam. Unique headlamp and taillight treatments help define the 3 Series' character, and the 17- and 18-inch wheels that are part of the optional Sport Package impart an even more aggressive stance than the standard 16-inch alloy rims. Bought the car in June. I keep up with the maintenance.
The rpms will spike to 750-800 rpms and drop below 5-400 rpms randomly causing the entire car to shake violently, and stall at times. Any inputs are appreciated; thanks! The bolts are made from aluminum -- they break. This also causes a huge issue for the driver of the car as you can't see the road in front of you. But the dealers told our producers that it was not a safety concern. When the injectors leak a considerable amount, this will make the spark plugs very wet, which will in turn make it harder for the engine to ignite the spark plug and start the engine. It's just a question of who pays for it.
