Adaptive suspension: knocking sounds over minor bumps. Since I got the car end of December, I noticed a mild knocking sound when going over minor bumps on the road. It sounds like a loose exhaust mounting, or even like worn ball-joints on an old car, albeit quieter than that.

Took my car in to the dealer today for them to look over, expecting it to be a case of a missing exhaust mouth or two. The drew a blank on that and want the car back in two weeks to look at suspension. Not worried, as I'm sure they'll fix it but has anyone else heard of this or experienced it?

If your BMW suffers from VANOS rattling, then read on to find out how it affects your vehicle and what steps you can take to fix the problem once and for all. To get an idea of what causes VANOS rattling, you first need to know how the variable valve timing system works. VANOS consists of a camshaft gear that operates independently of the intake cam, a splined shaft that slots into the cam gear and a solenoid that controls oil flow to the VANOS shaft.

This action advances the intake valve timing for better fuel efficiency during cruising. Excessive axial play can also develop over time, leading to camshaft lash and the telltale VANOS rattle. The pistons, seals, and bearings within can also fail with age and use, eventually leading to VANOS rattling, if not complete failure of the variable valve timing system.

Engines fitted with high-performance camshafts are not only more susceptible to VANOS rattling, but the noise will likely be worse due to the higher cam lift and greater instances of camshaft lash. What Are the Warning Signs? Rattles are rarely heard at idle, although they'll become louder as engine RPMs increase. A noisy VANOS may drive you up the wall while driving, but it won't result in poor performance or engine damage, in most cases.

Signs such as a check engine light, rough idling, or a noticeable decrease in low-end power are usually a prelude to complete VANOS failure. If you're experiencing these issues in addition to rattling noises, then you'll need to have the entire VANOS system serviced as soon as possible. How Can You Fix the Problem? If a rattle is present, you should let your mechanic inspect the VANOS system and make any repairs or replacements that are needed.

VANOS is an amazing feature that gives your BMW engine better performance and efficiency, so it only makes sense to keep it in great shape for as long as possible. Some auto services are essential to maintain safety in your vehicle.

I have a i e My problems all started when I noticed that on some occasions I should have idle issues. I checked the DISA valve on my intake and saw that there was not flap in place.

I assumed that the previous owner removed the flap if the unit was faulty. Anyway, I purchased a second hand unit and the car seemed to run fine for a day or so. Then, I noticed that the car started to misfire and there was a knocking noise coming from the engine. The knocks increased with revs. Upon further inspection, I noticed that it was coming from the valvetronic motor.

The first thing I looked for was air leaks but could not find any.

While these noises may be a symptom of some different issues, all are usually related to a suspension component that has failed. When a suspension component has failed, the ride or the vehicle may be altered. If the failed component is not dealt with, it can lead to increasingly difficult and dangerous problems.

Many of the components that may cause a clunking or knocking noise are not only a part of the suspension, but help control the steering of the vehicle. Any issues regarding the steering or suspension of the vehicle should be looked at by a mechanic as they will only become worse over time. Depending on the vehicle, one or two ball joints per wheel and may or may not be load bearing. If a ball joint is beginning to fail, you may notice a clunking noise coming from the front wheels.

This clunking noise will become louder and more frequent over time. You may also notice that your steering has been affected by the bad ball joint, potentially causing vibration in the steering wheel. Sway bars can help keep a vehicle from rolling over when going around a sharp corner.

If the sway bar breaks or is damaged it may produce a clunking or knocking sound, especially when going over bumps. Your vehicle may also had more difficulty handling when the sway bar is damaged.

This helps translate the turning of the steering wheel to the direction of the tires. When a tie rod end is worn or loose, they may produce a clunking noise. Worn tie rod ends may also cause more play in the steering wheel, making turning more vague. A top-rated mobile mechanic will come to your home or office to determine the reason for the clunking or knocking noise from the wheels. The mechanic will then provide a detailed inspection report outlining the reason for the noise and the cost of any repairs that need to be made.

Telling a mechanic about any unusual sensations, in addition to the clunking or knocking noise, you may have observed, will help him or her understand what went wrong with the vehicle. The mechanic will begin by lifting the front of the vehicle off the ground and shaking the front tires to check for play. If there is play in the front tires, the mechanic will suspect bad ball joints. The mechanic will then remove the wheel and the control arm s in order to access the faulty ball joint.

He or she will then remove the old ball joint and replace it with a new one. The mechanic should also ensure that the new ball joint is properly lubricated in order to ensure longer life.

If the mechanic suspects that the sway bar has gone bad, the mechanic will begin by examining the sway bar bushings.
