We offer a complete solenoid valve seal kit / repair kit for the VANOS adjuster unit in S50B30 engines for various BMW models. Another well known problem with VANOS adjuster units is the special sealing rings of the solenoid valves in the VANOS adjuster unit, which tend to leak relatively quickly. This is due to the material used (NBR, nitrile butadiene rubber), which is not suitable for the high temperatures in the engine compartment.The problem is related to the unique shape of the groove. Although it is possible to use Viton (FPM/FKM) o-rings (we use these o-rings in our seal kits for the entire VANOS adjuster unit), there is a slightly higher risk of extrusion due to the unqiue shape of the groove.Therefore we opted, based on the shape of the standard sealing rings, for a special design that significantly reduces the risk of extrusion due to the flat and slightly wider inner side and offers higher contact pressure thanks to a u-profile on the outside with significantly stronger flanks. Here you have the opportunity to purchase these 4 sealing rings (2 small sealing rings, BMW reference number 11 36 7 830 828, 2 large sealing rings, BMW reference number 11 36 7 830 829) and therefore to ensure that the VANOS adjuster unit works as intended.

We offer a complete DISA repair kit (intake manifold adjuster unit) for M54 3.0l engines for various BMW models. In M54 engines, the DISA flap's very fragile plastic mounting can lead to engine damage if parts of the DISA unit enter the combustion chamber. The original parts are also very susceptible to wear due to their material (mainly plastic) and their double-sided rather than continuous mounting. A malfunctioning DISA unit quickly leads to power losses, as the optimal air supply can no longer be guaranteed depending on engine speed and load.If your engine is equipped with a DISA adjuster unit, you might experience the following symptoms: - loss of torque and power- loud clicking noises- suction noisesHere you have the option to replace the old, fragile plastic parts of the DISA unit with CNC-machined aluminum and steel parts, thus preventing engine damage. Replacing the plastic parts will restore the flap control to its original function, and installing the sealing ring will effectively prevent the intake of unwanted air.Like almost all of our products, the parts in this repair kit, especially the milled parts made of aluminum and stainless steel, were manufactured entirely in Germany. The tolerances of the milled parts are within tolerance class DIN ISO 2768-1-m to ensure a high level of precision.This repair kit includes the following parts: 1 x DISA flap1 x DISA indexing pin1 x DISA screw 1 x retaining ring 1 x screw for removing the old indexing pin 1 x stainless steel wire 1 x 5g temperature-resistant grease with PTFE additives1 x Viton o-ring

We offer a seal kit / repair kit for the top hydraulic cylinder 54347193449 / 54 34 7 193 449 (hinge cylinder) used in BMW E85 Z4 models.  The issue: A lot of BMW convertible owners are aware of the well known problem: After a while the hydraulic cylinders responsible for opening and closing the soft top start leaking and do not work properly anymore. The leak occurs when the installed o-rings, rod seals and piston seals wear out to a point that they are not able to withstand the pressure inside the hydraulic cylinder anymore. This is especially noticeable during the summer in warmer regions since the original materials are limited in terms of temperature resistance. What others offer: Most competitors source cheap, low-quality polyurethane rod seals (usually green or blue) from China, most of which are even lower-grade than the original rod seals which were already limited in terms of service life and heat resistance. Our solution: We wanted more than just a simple and cheap replacement but a solution that incorporated unparalleled longevity and durability. Therefore we developed two kinds of rod seals made from high-tech materials: High-Performance Polyurethane (HPU, red color) as well as heat and wear resistant Viton® (FPM/FKM, brown color). Viton has the same mechanical properties as our High-Performance Polyurethane, but has a far greater temperature resistance (from -20°C/-4°F to +204°C/+400°F) and is therefore the preferred material for vehicles in warmer regions. The rod seals are CNC-milled to our specifications within tolerance class DIN ISO 2768-1-f (fine) in Germany to ensure a high level of accuracy. Seal types: A hydraulic cylinder contains a rod seal, an o-ring (depending on the model, not always installed) and a one- or two-piece piston seal. If the hydraulic cylinder is leaking, you'll need to replace the rod seal (and the o-ring). If the hydraulic cylinder is not able to open and close the soft top properly anymore, you'll need to replace the piston seal. Attention: The provided seals may only be used with the following types of hydraulic fluid to ensure smooth operation and a long service life:- Genuine BMW hydraulic fluid CHF 11S/CHF 202, hydraulic fluids in accordance with standard DIN 51 524, HLP 32 or standard ISO 11158, HM 32

Viton has the same mechanical properties as our High-Performance Polyurethane, but has a far greater temperature resistance (from -20°C/-4°F to +204°C/+400°F) and is therefore the preferred material for vehicles in warmer regions. The rod seals are CNC-milled to our specifications within tolerance class DIN ISO 2768-1-f (fine) in Germany to ensure a high level of accuracy. Seal types: A hydraulic cylinder contains a rod seal, an o-ring (depending on the model, not always installed) and a one- or two-piece piston seal. If the hydraulic cylinder is leaking, you'll need to replace the rod seal (and the o-ring). If the hydraulic cylinder is not able to open and close the soft top properly anymore, you'll need to replace the piston seal. Attention: The provided seals may only be used with the following types of hydraulic fluid to ensure smooth operation and a long service life:- Genuine BMW hydraulic fluid CHF 11S/CHF 202, hydraulic fluids in accordance with standard DIN 51 524, HLP 32 or standard ISO 11158, HM 32

We offer a seal kit / repair kit for the top hydraulic cylinder 54347193450 / 54 34 7 193 450 (hinge cylinder) used in BMW E85 Z4 models.  The issue: A lot of BMW convertible owners are aware of the well known problem: After a while the hydraulic cylinders responsible for opening and closing the soft top start leaking and do not work properly anymore. The leak occurs when the installed o-rings, rod seals and piston seals wear out to a point that they are not able to withstand the pressure inside the hydraulic cylinder anymore. This is especially noticeable during the summer in warmer regions since the original materials are limited in terms of temperature resistance. What others offer: Most competitors source cheap, low-quality polyurethane rod seals (usually green or blue) from China, most of which are even lower-grade than the original rod seals which were already limited in terms of service life and heat resistance.
