Oil-bath belt on the 1.2 Turbo and chain on the 1.5 Diesel in the Astra K

Engine / equipment

Opel Astra K from 2019: three-cylinder 1.2 Turbo and 1.5 Diesel

Period mentioned

2019–2021

Symptoms

1.2 Turbo: the timing belt runs in oil and, with the manual gearbox, there have been cases of crankshaft end play. 1.5 Diesel: rattling on a cold start or under load changes from a stretched chain, risking engine failure. On all: oil leaks that fail the roadworthiness test.

Possible cause described

The 1.2 Turbo lasts if oil changes are kept with the correct oil; the German guide recommends the automatic. The chain problems of the earlier 1.6 CDTI were never fully solved and also affect the 1.5 Diesel. Recalls: high lambda at inspection (2017–2019, software), seat welding (2019), AdBlue-pump diagnostics (from 2019) and wheel-bolt torque (2019–2020).

Check for the garage

Ask for the oil-change history; listen on a cold start; check for oil leaks and campaigns by VIN.
