The S54 vanos is now known for rattling, and a rebuild is a much cheaper option than the dealers. If you're looking for an inexpensive alternative to a new E46 M3 vanos from the dealer, we can provide a fully rebuilt unit with brand new solenoids and solenoid valves at a very reasonable price.
Another problem we have discovered is down to 12 bolts that hold the cam wheels to the cam. They are working loose and eventually snapping. There are 6 per cam and if they fail then the engine would be destroyed. The pictures below show the state of 6 bolts on the intake camshaft. 2 snapped are 4 stripped and grooved. This was repaired just in time.
On this particular car the exhaust camshaft, vanos oil pump spline had sheared off. This car had covered 70,000 miles.
The E46 M3 vanos comes fully rebuilt with brand new solenoids and solenoid valves. This is the exact same package the dealers sells, but ours is half the price.
IF YOUR VANOS IS NOT SERVICEABLE THERE IS A SURCHARGE PAYABLE. ANY FAULTY SOLENOIDS ARE ALSO CHARGABLE PER PAIR.
You can come to our workshop to have the vanos fitted, if you are travelling a long distance you can stay overnight at our expense.
If you visit us why not have your car serviced at the same time. We only use geunine BMW parts and all work is carried out to a high standard. Warranty will not be affected
