Most common problems, symptoms & fixes for the QQDB engine.

Engine QQDB, found in Ford Focus 1.8 16V (2005–2011) and C-Max 1.8 16V (2009–2010), commonly faces issues like timing chain wear, leading to rattling noises and potential engine damage. Diagnosis involves listening for unusual sounds and checking timing chain tension. Prevent by adhering to regular oil changes with quality oil to ensure proper lubrication. Another frequent problem is EGR valve clogging, causing rough idling and reduced performance; cleaning or replacing the EGR valve resolves this. Additionally, inspect ignition coils and spark plugs regularly to prevent misfires. Timely maintenance and addressing symptoms early help prolong engine life and reliability.
