Inside Line: Meyle

Sven Nielsen, Technical Director from MEYLE, says the following difficulties may arise with the BMW 3 Series:

Damaged oil pans

Problem:

Oil pans fit BMW models with 6 speed automatic transmissions. Supposedly a sealed for life system but the plastic sump can warp causing loss of ATF.  This is indicated by a lumpy gearchange. It must be used with non-conductive ATF to protect the transmission mechatronics.

MEYLE Solution: MEYLE oil pans for BMW ensure increased reliability

Normally, the oil pan is also replaced with every repair or filter replacement. Exchanging the oil pan sometimes helps remedy early-stage shifting problems making it a cost-effective yet short-term alternative to time and cost intensive automatic transmission repair.

Oil pans help dissipate gearbox heat which is why they are subjected to high temperature fluctuations. As they are made from different materials with different thermal expansion properties, oil pans must have an extremely robust design. In addition, the materials used for the plastic pan and rubber pan sealing must ensure superior long-term resistance to the oil in the system, whether new, used or contaminated. The oil pan has two permanent magnets, just like the original. These are intended to bind iron particles, which may rub off and collect in the oil during the vehicle’s life and prevent them from continuing to circulate in the gears. This reduces wear and tear on the parts in the gears.

Worn out control arm bushings

Problem:

Control arm bushings are exposed to strong forces during acceleration, braking and cornering. Bad roads or weather conditions can also contribute towards them becoming worn and less effective. Steering play may arise and an accurate lateral guidance is no longer possible. Worn control arm bushings will in turn place increased stress on other suspension components and can cause wear throughout the suspension. This may lead to lower levels of safety and costly repairs to the chassis.

MEYLE Solution:

Hydro-filled mounts are the latest trend in OE engineering, they often fail to live up to expectations as they are susceptible to leaking and hence early failure. Therefore, the expert team at MEYLE uses only full-rubber mounts to increase the reliability of MEYLE-HD spare parts. In addition, MEYLE in-house engineers precisely attune the damping performance of MEYLE-mounts to the characteristics of the OE system, thereby ensuring sustained driving comfort. With MEYLE-HD full-rubber mounts MEYLE offer a fail-safe alternative to hydro-filled mounts and a solution that delivers what it promises.

Stabiliser links often worn out

Problem:

Intense strain and high surface pressure wear and stress on the ball joint (head Ø 16mm). This causes a premature failure of the ball joint and generates noise at the front axle.

MEYLE-HD Solution:

MEYLE in-house engineers increased the diameter of the ball head of the ball joint to 22 mm, in addition to using wear-resistant synthetic ball sockets with high-tech grease. The reduction of the surface pressure ensures a significantly longer lifetime.

Owing to the larger ball head the ball surface on MEYLE-HD stabilizer links has been increased by 50%. This way we have managed to significantly improve the part‘s load carrying capacity along with its service life. The blue clip-on plastic socket adds additional strength to the MEYLE-HD part.
