CERMA FOR VANOS SYSTEMS Cerma STM-3 Vanos is designed to be used AFTER vehicle has been TREATED with Cerma STM-3 Engine Treatment. If you have already treated your vehicle, select Cerma Vanos Treatment only. If you have not, select the Cerma Engine Treatment additional option. The combined Vanos and Engine Treatment price have been discounted for your benefit. BMW Vanos Seal Extended Life: Do you own a BMW, 1993-2006? If so then your vanos, engine variable valve timing unit, is most likely failing. These vanos units have been consistently diagnosed to fail due to deteriorating piston seal O-rings. The O-rings are made of rubber that is drying out in the engines environment. This causes the vanos piston seals to lose their sealing function and for the vanos unit to fail. BMW does not provide the vanos seals separately. It sells rebuilt vanos units for ~$1500 installed. New rebuilt vanos units are supplied with the same failing rubber O-rings and have been found to fail in as little as 20k miles (32k kilometers) of use. Vanos seal extended life is here!. Cerma STM-3 Vanos Treatment will revitalize the O-rings and provide an easy to apply fix. No need to be without your car while mechanic replaces vanos unit, just pour in oil and drive. So easy! Even a novice can do it. Cerma Vanos is a "one-time" treatment, no need for additional product for the life of the unit. Within 100-500 miles you will notice improved performance, no rattle start ups, more power, overall performance gains. AGREE: I understand that vehicle must be treated with Cerma STM-3 Engine Treatment prior to using Cerma Vanos
