Timing Chain Fault Audi A1

We’ve recently had this Audi A1 TSFI in with a Timing Chain fault.

Symptoms for issues with the timing chain will give 1 of 2 faults. The engine will either be rattly from cold start/just generally rattly or you will get an engine management fault code for cam crank coherent.

The issues arise as worn out oil can no longer lubricate the chain and will cause the rollers and links to wear against each other. As the chain runs around the gears of the camshafts and crankshaft, the movement between the rollers and links causes wear and elongation. Timing chain stretch is not the stretching of the timing chain, it is an elongation of the timing chain.This is caused by wear to the chain’s components. The most common cause of timing chain stretch is lack of maintenance and regular oil changes.

As the timing chain wears, this can change the timing of the camshaft and crankshaft. The change in timing is sensed by the camshaft and crankshaft position sensors. This can cause codes that indicate a correlation problem with the engine position sensors.

If the driver ignores the check engine light; Eventually the timing chain will elongate to the point that the engine may have a significant loss of power.

Chains were designed to last the lifetime of the engine. However, due to poor design, the chains stretch, tensioners fail therefore inevitably this causes severe engine damage.

This is a common problem in vehicles with 1.4 TFSI and 2.0 TSI engines.

In conclusion if you have any untoward noises on the engine please seek advise!

Timing chain fault audi

Modern day engine design is seeing the use of timing chain in 70% of engines. But with failures happening on a regular basis have they got the designs right?

We are replacing timing chains on engines from as low as 40,000 miles. Why you may ask?

In the pursuit of a light weight, low drag, eco friendly engines some cutbacks have to be made. The design of modern engines is not so over engineered as engines were 15 years ago.

The most common early signs of chain failure are:

Rattle on engine from cold start

Engine management light on with fault codes such as P0016  P0008  P1340  P0011    16400   17748

Lumpy and uneven idle

loss in power

We only use genuine timing chains when replacing the worn / stretched parts. Using the manufactures tooling we can accurately set the engine timing prior to removal and replacement of components.

If a chain is left un replaced when it is showing signs of pre failure the results can be extensive if failure occurs. This normally results in extensive repair costs, or in some cases replacement of engine is more cost efficient.

Keeping your vehicles service history up to date can help prolong the life of the chain.
