Opel Astra
Factory-prepared B10XE with hardened valve seats for LPG use. Shares all B10XE weak points; LPG switchover problems in cold weather are known.
Three-cylinder entry level
66 kW from the 1.0 three-cylinder – tight but rev-happy in the Astra K.
Engine Weaknesses 8
The timing cover can develop an internal leak: coolant enters the oil. No external leak visible, so it is often detected late.
Symptoms: Slow coolant loss, milky oil, no visible external leak.
Turbocharger failures were reported in the 1.0 Turbo in Adam and Astra K/Corsa E after around 75,000 km. Typical: whistling noise even at idle. Repair costs approx. 800–2,500 €.
Symptoms: Whistling or rattling noise from the engine bay, power loss, bluish smoke when accelerating.
Identical problem to the B10XE: solenoid fails, fault codes P0011/P0014/P0017. Engine hesitates.
Symptoms: Hesitation and rough idle, MIL light, fault codes P0011/P0014/P0017.
The turbo oil feed line on the B10XFL becomes porous from heat and age. Oil contacts the hot turbocharger and evaporates, which can lead to turbo bearing damage internally. Opel covered costs partially as goodwill for vehicles within mileage limits.
Symptoms: Oil smell in the cabin and engine bay, bluish smoke from the engine bay, power loss if oil loss is severe.
The B10XFL Turbo generates higher combustion pressure due to turbocharging, which wears piston rings earlier. From around 100,000 km drivers report consumption above 0.5 litres/1,000 km. Short oil change intervals slow wear.
Symptoms: Dropping oil level between change intervals, bluish smoke under load changes, occasional power loss.
Like the B10XE, the B10XFL in the Opel Astra K and Corsa E also tends to ignition coil failure with misfires under part throttle. Spark plugs should be replaced at the same time.
Symptoms: Hesitation at low RPM, MIL with misfire detection, rough idle during warm-up phase.
At sub-zero temperatures the engine switches from petrol to LPG late or not at all. The vaporiser takes too long to reach operating temperature.
Symptoms: Vehicle stays on petrol after cold start, LPG indicator does not switch, elevated consumption in winter.
The VVT solenoid on the B10XFL develops an oil leak at the timing cover. Visible as a light oil stain in the engine bay. Replacing the solenoid including seal costs 150–300 € at a workshop.
Symptoms: Light oil contamination at the timing cover, occasional oil smell after driving, rarely fault codes for variable valve timing.

The clutch slave cylinder seal dissolves and contaminates the hydraulic system. Affects diesel manual gearbox models 2016–2018. Recall number 181803130.
The M32 6-speed manual gearbox shows stiff gear engagement especially cold, particularly 2nd and 3rd gears. Air in the clutch hydraulics or a faulty clutch slave cylinder are the common causes.
Water from the wheel arch runs onto the plastic mounting bracket of the engine carrier and promotes corrosion from the inside out. Rust warranty applies for 12 years with a complete service history.
Rear coil springs can break prematurely due to corrosion at the spring seat, sometimes as early as 38,000 km. Rust grips the spring root. Grounds for MOT failure.
LED headlights on the Astra K fail sporadically due to loose connectors and faulty control units. Mainly affects early production years 2015–2017.
The Astra K shows chronic oil loss at various gaskets according to ADAC and MOT reports. Visible oil residue on the underbody leads to rejection at the MOT.
Squealing noises from the EPS steering at high temperatures are a known Astra K issue. In severe cases the steering assist cuts out. Cause: steering rack wear or electrical connections.
The display on the Navi 900 IntelliLink flickers, stays black, or shows colour errors. Hardware defect at the display panel. Replacement costs around €160 (used) to €1,250 (new).
The first HMI module in the Astra K (pre-2016 recall) freezes or becomes unresponsive. Sporadic audio dropouts can still occur even after updates.
The infotainment system on the Astra K regularly freezes or crashes. Navigation and Apple CarPlay stop responding. Often fixable by a software update, but the problem returns.
The rear brake discs on the Astra K corrode noticeably faster than the fronts according to MOT reports. With standing time or low brake usage they rust up and must be replaced prematurely.
On the Astra K the fresh air channel drain becomes blocked by leaves and debris. Water then runs into the cabin (driver's footwell or rear left).
The blend door actuator in the Astra K fails. Temperature can then no longer be regulated — regardless of the dial position, only cold or only hot air comes out.
The A-pillar trim on the Astra K detaches or warps and rattles while driving. Also crackling noises from the passenger door.
Reports & Tests
Oil loss remains the dominant problem. On the Astra K, infotainment failures, juddering 1.4 turbo engines and fogged driver assistance camera lenses are additional issues. Recalls affected defective airbag inflators and brake master cylinders.
