Audi A5 timing belt cost
The Audi A5 mirrors the A4: the 1.8 and 2.0 TFSI petrols use a timing chain, the 2.0 TDI diesel uses a timing belt, and the 3.0 TDI V6 uses rear-mounted chains rather than a serviceable cambelt. A timing belt change at a UK independent garage typically costs £265–£752 for a Audi A5 (belt, tensioner and water pump), depending on engine.
Does the Audi A5 have a belt or chain?
It depends on the engine. Here's the belt-vs-chain breakdown for the main UK Audi A5 engines, with typical manufacturer replacement intervals (always confirm against your own handbook):
| Engine | Type | Interval |
|---|---|---|
2.0 TFSI petrol (EA888, B8/B9) Chain, no scheduled interval. Earlier Gen 1/Gen 2 engines are prone to chain stretch; the Gen 3 redesign improved durability. | Timing chain | No set interval |
1.8 TFSI petrol (EA888) Chain, no fixed interval; same family and chain concerns as the 2.0 TFSI. | Timing chain | No set interval |
2.0 TDI diesel Cambelt. Audi UK guidance has commonly been around 5 years or 75k miles. Replace water pump and tensioners with the belt. | Timing belt | 75,000 mi / 5 yr |
3.0 TDI V6 diesel Several timing chains mounted at the rear of the engine, not a conventional serviceable cambelt; no routine interval. | Timing chain | No set interval |
3.0 TFSI V6 supercharged petrol (S5) Chain, no scheduled interval. | Timing chain | No set interval |
Audi A5 timing belt cost
For belt engines, a full timing belt service (belt, tensioner and water pump) at a UK independent garage typically costs £265–£752. Main dealers charge 30–50% more. Chain-driven variants have no scheduled change but cost more in labour if a chain fails.
Key things to know
- The A5 follows the A4 mechanically: TFSI petrols are chain, the 2.0 TDI is belt.
- The 3.0 TDI V6 has rear-mounted chains, so it has no routine cambelt service.
- EA888 petrol chains have no fixed interval but can stretch on earlier engines — watch for cold-start rattle.
- UK dealers often apply a 5-year safeguard on the TDI belt even where mileage limits are higher.
Good question
Questions Okay gets asked a lot
How much does a timing belt cost for a Audi A5?
+
A timing belt replacement on a Audi A5 typically costs £265–£752 at a UK independent garage in 2026, covering the belt, tensioner and water pump together. The exact figure depends on the engine and your area; main dealers charge more. Use our cost calculator to estimate the price for your specific car and region.
Does the Audi A5 have a timing belt or a timing chain?
+
It depends on the engine. The 1.8 and 2.0 TFSI petrol engines use a timing chain with no scheduled replacement. The 2.0 TDI diesel uses a timing belt that must be replaced periodically. The 3.0 TDI V6 uses chains mounted at the rear of the engine rather than a serviceable cambelt. Identify your engine code to be sure which system your particular A5 uses.
What is the cambelt interval on an Audi A5 2.0 TDI?
+
Audi UK has commonly recommended changing the cambelt on the 2.0 TDI at around 5 years or roughly 75,000 miles, whichever comes first, though some guidance and later engines allow considerably higher mileage. It is sensible to replace the water pump, tensioners and any secondary oil-pump belt at the same time. Because intervals vary by build year, always confirm against your own service schedule.
What happens if the timing belt snaps on a Audi A5?
+
Its belt-driven engines are interference designs, which means if the belt snaps the pistons strike the open valves. That causes bent valves and often piston and cylinder-head damage — a repair that frequently runs to four figures and can write off an older car. This is why replacing the belt on schedule, by age as well as mileage, is far cheaper than risking a failure.
