WHY SHOULD I CONSIDER VANOS RENEWAL?
Symptoms of this failure include; overall loss of power and torque particularly in the lower RPM range, loss of power with air conditioning on, louder idle, increased fuel consumption and difficult cold weather starts and even stalls.
The seals fitted to the pistons within your vehicles Vanos unit wear prematurely because they are constructed of poor quality materials; causing loss of torque and power!
If you drive a BMW 6 cylinder vehicle 1993-2006 your Vanos (variable valve timing unit) is most likely failing. The O-rings ﬁtted to the pistons within the Vanos unit wear prematurely because they are constructed of poor quality Buna rubber which is not suited to the elevated temperatures of their location. The seals fail and lead to Vanos unit failure. BMW do not provide replacement seals, they do provide complete Vanos units at vast expense but these again are ﬁtted with the same poor quality seals that will fail again.
Even if your car is a low mileage example- your seals will very likely be at end of useful life.
MY BMW Z4 ROOF HAS STOPPED WORKING!
A common fault seen on all BMW E85 models-
The electric motor that drives the roof mechanism is located in a pocket, tucked away behind the passenger side door.
Poor design means the drain in that area gets blocked by leaves, the well fills with water and enters the motor, causing it to fail: no roof operation!
Your roof motor is removed from the well and inspected. In most cases it can be restarted. Once its operating again, it is relocated to the boot areas if it fails again, its easier to inspect, refill and replace.
Other common issues resolved from wiring/loom issues.
