Where is the cam sensor on a 1997 325I BMW located and cost to repair?

The camshaft position sensor (CPS) on a 1997 BMW 325i (E36) is located on the rear of the cylinder head, near the firewall (the metal bulkhead separating the engine compartment from the passenger compartment). It's usually quite accessible once you get to it, although working in that area can be tight. You'll likely need to remove some components to get a clear view and reach.

Exact location can vary slightly depending on the engine variant (M52TU or M52). A detailed diagram in a repair manual specific to your car's VIN will be the most accurate.

Cost to Repair:

The cost to repair a faulty camshaft position sensor varies greatly depending on where you get the work done and whether you do it yourself.

* Part Cost: The sensor itself is relatively inexpensive. You can find them online or at auto parts stores for anywhere from $30 to $100, depending on the brand (OEM vs. aftermarket).

* Labor Cost: This is where the cost can escalate significantly. If you take it to a shop, expect to pay anywhere from $100 to $300+ in labor charges, depending on the shop's hourly rate and the difficulty accessing the sensor in your particular car. Factors like the need to remove other parts to access the sensor will add to the labor.

* DIY Cost: If you're mechanically inclined, you can significantly reduce the cost. The main expense would then be the sensor itself. However, factor in the cost of any special tools you might need.

In summary: Expect to pay anywhere from $50 (DIY with inexpensive sensor) to $400+ (professional repair) for the repair of a faulty camshaft position sensor on your 1997 BMW 325i. A more precise estimate requires knowing the specific issues and if any related problems were discovered during diagnostics.
