Timing Chain Replacement

The timing chain synchronises the rotation of the crankshaft and camshaft(s), ensuring that the engine's valves open and close at the correct point in the combustion cycle. Unlike a timing belt, a timing chain is designed to last the life of the engine - but in practice, chain stretch, guide wear, and tensioner failure can cause the chain to become loose, skip teeth, or in worst cases, snap. A failed timing chain on an interference engine causes catastrophic damage as the pistons strike the open valves. At Luxury Auto Care Dubai, we perform timing chain inspections and replacements for all luxury car brands.

Symptoms of a worn or failing timing chain include a rattling noise from the engine on startup (especially when cold), rough idling, engine misfires, and a check engine light with camshaft position correlation fault codes. In some engines, the chain stretch is gradual and may not produce obvious symptoms until significant damage has occurred. We recommend inspection of the timing chain system at regular intervals, particularly on engines known for premature chain wear such as certain BMW, Audi, and Mercedes-Benz models.

Our timing chain replacement service includes removal of the timing cover, inspection of the chain, guides, tensioners, and sprockets, and replacement of all components in the timing system. We use genuine OEM or high-quality aftermarket timing chain kits that include the chain, guides, tensioners, and sprockets as a complete set. After installation, we verify timing alignment and engine performance through diagnostic scanning and road testing. Timing chain replacement is a preventive investment that protects your engine from catastrophic failure.
