Symptoms of this failure include; overall loss of power and torque particularly in the lower RPM range, loss of power with air conditioning on, rattling sounds from the Vanos unit, louder idle, increased fuel consumption and difficult cold weather starts and even stalls.
THE CAUSE
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.
It is also common for the Vanos unit to develop a rattle which can often be heard within the vehicles cabin. This rattle is caused by wear in the variable valve timing gears. This wear allows axial play and causes components to rattle. Removing the Vanos pistons axial play reduces this rattle significantly.
