If you drive a BMW 6 cylinder vehicle 1993-2006 your Vanos (variable valve timing unit) is most likely failing. The seals fitted to the pistons within the Vanos unit wear prematurely. These seals are constructed of poor quality Buna rubber which is not suited to the elevated temperatures of their location; this leads to the seals failing and ultimately the Vanos unit failing.
Symptoms of fault
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. BMW does not provide replacement seals, they do provide complete rebuilt units at vast expense but these again are fitted with the same poor quality Buna rubber seals.
The fault
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!
