Timing Chain
What's that rattling?!
If you've started hearing a metallic rattling engine noise for a few seconds when starting your car, a worn or stretched timing chain could be the culprit.
Check your dashboard warning lights
Timing chain issues often trigger engine warning lights or camshaft/crankshaft fault messages.
Diagnosing a Timing Chain fault
We employ the latest in diagnostic equipment to detect and decode errors captured by your vehicle's computer system. There isn't a specific Timing Chain error code but here are some typical fault codes that can often be associated with timing chain issues:
-
P0016/P0017 (cam/crank correlation)
-
P0340/P0341 (camshaft position)
-
P0335 (crankshaft position)
Our experienced technicians will use these codes and their wealth of working knowledge to diagnose any engine faults including issues with your timing chain.
Why diagnostics is often required
Timing chains are not inspected as part of a routine service or MOT because they run inside the engine. Diagnosis of a timing chain issue usually involves a combination of diagnostics, noise assessment, and manufacturer guidance rather than visual inspection alone.
If you believe there may be an issue with your timing chain we recommend booking a diagnostic test.
