2010 Ford C-Max 2.0 TDCi (140) Trend (Zetec) PowerShift (d-cl. 6) – Workshop Service & Repair Manual

Transmission problems can manifest as hard shifting, slipping, or unusual noises. Follow these steps to diagnose and address the issue:

1. Check Fluid Levels: Ensure the transmission fluid is at the correct level. Low fluid can cause shifting problems.
2. Inspect Fluid Condition: Look for signs of contamination, such as a burnt smell or dark color. If the fluid is contaminated, consider a transmission flush.
3. Scan for Error Codes: Use an OBD-II scanner to check for transmission-related error codes.

Check for Leaks: Inspect the transmission for any fluid leaks, which might indicate a faulty seal or gasket.

 Common turbocharger issues include loss of power or excessive smoke. To address these:

1. Check for Boost Leaks: Inspect the turbocharger and associated hoses for any signs of leaks or damage.
2. Inspect the Turbocharger: Look for any signs of excessive play in the turbo shaft or unusual noises.
3. Clean the Turbo: Accumulated debris can impair turbo function. Consider a professional cleaning if necessary.

Check Oil Supply: Ensure the turbocharger has adequate oil supply and that the oil lines are not clogged.

EGR valve failure can lead to poor engine performance and increased emissions. Here’s how to address it:

1. Inspect the EGR Valve: Look for signs of carbon buildup or damage.
2. Clean the Valve: Use a suitable cleaner to remove carbon deposits from the valve and its passages.
3. Check the EGR System: Ensure all connections and hoses are intact and free of leaks.

Replace if Necessary: If cleaning doesn’t resolve the issue, consider replacing the EGR valve with a new one.

DPF clogging can cause performance issues and increased emissions. Follow these steps to address it:

1. Perform a Regeneration: Drive the vehicle at high speeds for a sustained period to allow the DPF to regenerate and burn off soot.
2. Check for Fault Codes: Use an OBD-II scanner to check for DPF-related error codes.
3. Inspect the DPF: Look for physical signs of damage or excessive blockage.

Clean or Replace the DPF: If regeneration does not clear the clog, professional cleaning or replacement may be required.

 Electrical issues can manifest as warning lights, malfunctioning accessories, or dead batteries. Here’s how to troubleshoot:

1. Check Battery Connections: Ensure the battery terminals are clean and securely connected.
2. Inspect Fuses and Relays: Look for blown fuses or faulty relays in the fuse box.
3. Scan for Error Codes: Use an OBD-II scanner to identify any electrical system-related error codes.

Examine Wiring: Inspect visible wiring for damage or loose connections.
