A pre-purchase inspection by a Mercedes specialist is highly recommended, especially for the starter, alternator, and suspension components.

      How much does it cost to replace the starter on a 2002 Mercedes-Benz C240, and what steps are involved?

      Replacing the starter on a 2002 C240 typically costs $300–$800 (parts + labor). The starter is located behind the engine’s right side, near the alternator. Disconnect the battery, remove the air intake, and unbolt the starter—labor can vary by shop, but expect 1–2 hours of work.

      What are the most common problems reported with the 2002 Mercedes-Benz C240?

      The 2002 C240 is notorious for starter failures, oil leaks (valve cover gasket, oil pan), and electrical issues (window regulators, door lock actuators). Suspension wear (control arms, bushings) and transmission hesitation (if equipped with the 5-speed auto) are also frequent complaints.

      Is the 2002 Mercedes-Benz C240 reliable, and what should potential owners expect long-term?

      The C240 is moderately reliable but plagued by electrical and mechanical quirks. With proper maintenance (regular oil changes, starter/alternator checks), it can last 200K+ miles, but owners often face costly repairs for the starter, suspension, or interior wear. It’s a solid driver but not as bulletproof as later models.

      Where can I find a 2002 Mercedes-Benz C240 fuse box diagram with accurate fuse locations?

      Official diagrams are available in the 2002 C240 owner’s manual (Chapter 12) or via Mercedes-Benz’s WIS (Workshop Information System). Free alternatives include Haynes repair manuals or online forums like MercedesBenzForum.com, which host user-uploaded fuse box images with labeled locations.

      What is the oil capacity for a 2002 Mercedes-Benz C240 with the 2.4L engine, and what type of oil should I use?

      The 2002 C240’s 2.4L M240 engine holds 5.5 quarts (5.2 liters) with filter change. Use Mercedes-Benz 229.51 or 229.52 (5W-40 or 5W-30 synthetic) or equivalent API SL/CF oil meeting MB 229.5 specs. Always drain old oil first, then refill to the "max" dipstick mark.
