2012 Ford C-Max 1.6 TDCi (95) Titanium – Workshop Service & Repair Manual

Turbo failure in the 2012 Ford C-Max 1.6 TDCi can lead to reduced engine performance, excessive smoke, or strange noises. Here’s a step-by-step guide to address the issue:

1. Check for oil leaks: Inspect the turbo and surrounding areas for any signs of oil leakage, which could indicate a failing turbo seal.
2. Examine the turbocharger for damage: Remove the intake hose and visually inspect the turbocharger for damage to the turbine blades or excessive play in the shaft.
3. Check the intercooler: Ensure the intercooler is clean and free from obstructions, as a clogged intercooler can cause turbo failure.
4. Inspect the turbo hoses: Look for cracks or splits in the turbo hoses that might cause pressure loss.

Replace the turbocharger: If damage is evident, the turbocharger may need to be replaced. Follow the instructions in our Workshop Service & Repair Manual for a detailed guide on turbo replacement.

Oil supply issues can lead to engine wear and potential failure if not addressed promptly. Here’s how to resolve the problem:

1. Check the oil level: Start by checking the oil level using the dipstick. Ensure it's within the recommended range.
2. Inspect the oil filter: A clogged oil filter can restrict oil flow. Replace it if it hasn’t been changed recently.
3. Examine the oil pump: If oil pressure is low, the oil pump might be failing. Check for any unusual noises coming from the pump.
4. Check for leaks: Inspect the oil pan, gaskets, and seals for any signs of leaks.

Top up or change the oil: If the oil is low or dirty, top it up or change it as needed. Use the oil grade recommended in our manual for the best results.

Electrical problems in the Ford C-Max can range from faulty wiring to malfunctioning sensors. Follow these steps to troubleshoot and fix common electrical issues:

1. Check the fuses: Start by checking the fuse box for any blown fuses. Replace any that are damaged.
2. Test the battery: Use a multimeter to check the battery voltage. A weak battery can cause electrical issues.
3. Inspect the wiring: Look for any frayed or damaged wires, especially around the engine bay and under the dashboard.
4. Check the alternator: A failing alternator can lead to electrical failures. Test the alternator output with a multimeter.

Scan for fault codes: Use an OBD-II scanner to check for any fault codes that might indicate the source of the problem.

Poor door seals can lead to water ingress and increased road noise. Here’s how to address door sealing problems:

1. Inspect the door seals: Check all door seals for signs of wear, tears, or hardening of the rubber.
2. Clean the seals: Use a mild detergent and water to clean the seals, removing any dirt or debris that might be causing leaks.
3. Lubricate the seals: Apply a silicone-based lubricant to keep the seals supple and improve their effectiveness.
4. Replace damaged seals: If the seals are damaged, replace them with new ones following the instructions in our manual.

Check door alignment: Ensure the door is properly aligned, as misalignment can cause sealing issues.

1. Identify the leak: Check under the vehicle and around the coolant pump for signs of coolant leakage.
2. Inspect the coolant hoses: Ensure the hoses connected to the pump are secure and free from cracks or wear.
3. Check the coolant pump gasket: A worn gasket can cause leaks. Inspect the gasket for any signs of wear or damage.
4. Replace the coolant pump: If the pump itself is leaking, it will need to be replaced. Follow the detailed procedure in our manual to ensure proper installation.

Refill and bleed the system: After replacing the pump, refill the cooling system with the correct coolant and bleed any air from the system.
