Timing chain
Volkswagen · Audi · Škoda · SEAT · 2008 onwards. Chain, not belt — but early Gen 2 units suffered tensioner failure. A rattle for a second on cold start is the warning.
Commonly Golf GTI, A4, A5, Superb, Tiguan (2008 onwards). Engine codes changed through production, so confirm the code on the car in front of you before ordering parts or quoting the job.
The 1.8 / 2.0 TSI (EA888) used by Volkswagen, Audi, Škoda, SEAT (2008 onwards) runs a timing chain. Chain, not belt — but early Gen 2 units suffered tensioner failure. A rattle for a second on cold start is the warning.
There is no scheduled replacement interval for a chain. Judge it on cold-start noise, fault codes and oil-service history instead.
Expect roughly £900-£2,200 at a UK independent garage, depending on whether the water pump and tensioner go in at the same time and how much has to come off to reach the belt. Main-dealer quotes usually sit above that range.
On an interference engine the valves and pistons meet, which usually means a cylinder head at best and a replacement engine at worst. That is why an unproven timing history is a price conversation, not a detail.
Commonly Golf GTI, A4, A5, Superb, Tiguan (2008 onwards). The list is not exhaustive and engine codes changed through production, so confirm the exact code on the car in front of you before ordering parts or quoting work.
