Check engine light (MIL) – complete dissection
- O2 sensor (P0130-): rough idle, fuel smell
- Ignition coil (P0300-): misfire, jerking
- AdBlue system (P20EE): reduced power, countdown
- EVAP (P0442): small leak, fuel cap
- EGR (P0401): pinging, hesitation
- 1. OBD2 scanner – read freeze frame, live data
- 2. Opel specific: Diagbox / GDS2 – actuator tests
- 3. Smoke test for evap/intake
- 4. Fuel trim analysis (LTFT/STFT)
- 5. Compression test (PureTech 1.2)
Oil pressure warning (red) – stop! engine damage risk
- 🔧 Step-by-step: Check level & viscosity – replace switch (common Crossland failure) – inspect wiring – if ok, suspect oil pump or blocked pickup (PureTech wet belt).
- 📊 Advanced: borescope oil pan, pressure test port. 1.5 CDTI diesel: often oil pressure regulator valve.
AdBlue & NOx warning – diesel Crossland
amber then red countdown (usually 1100km). Top 3 faults:
Brake warning (red) & electronic parking brake
- Red brake circle – low fluid, handbrake on, pad wear sensor (Crossland has rear pad wear sensor).
- Amber (PARK) – EPB fault: calibration, switch, motor. Often after battery change.
- Diagnosis: check fluid level, inspect pads, scan EPB codes. For EPB relearn: 12V supply, actuator reset via scan tool.
TPMS – indirect & direct systems
Opel Crossland: 2017-2020 indirect (ABS based), 2021+ direct sensors. Indirect: reset via menu, needs reinitialisation after tyre rotation. Direct: sensor battery life ~5-7y.
Power steering warning – EPS
red/amber: heavy steering, intermittent assist. Crossland (CMP platform) common torque sensor failure, also low battery voltage.
- Diagnose: battery test, EPS module codes, torque sensor calibration, steering angle sensor reset. GDS2 can perform calibration.
Airbag warning (SRS)
- Crossland specific: passenger occupancy sensor mat (under seat), clock spring, front seat belt tensioner. Codes B1000, B1340.
- Diagnosis: check under seat connectors (yellow), scan with Diagbox. Never measure resistance with multimeter – use proper diagnostic.
Coolant temperature / level warning
Blue = cold; red = overheating. 1.2 PureTech known for thermostat housing leaks, electric water pump failure. Also low coolant sensor on expansion tank.
DPF warning – regeneration required
amber / flashing: additive level, ash load, forced regen needed. 1.5 CDTI: DPF pressure sensor, add blue fluid (Eolys).
- Diagnosis: measure differential pressure, check additive level, perform forced regen with scanner.
Stop-start inactive / ECO warning
Usually amber symbol with A crossed. Causes: battery state of charge <75%, bonnet switch, outside temp, brake vacuum, recline seatbelt.
Lane departure / forward collision / traffic sign
Amber/orange symbol: camera blocked (frost, dirt), calibration off, windscreen replacement need recalibration.
Automatic transmission / gearbox fault
Crossland 1.2 with EAT6 / EAT8: “gearbox fault” message, limp mode. Common: oil pressure solenoid, valve body wear. Also low oil level.
Immobiliser / key not detected
Key symbol amber: dead key battery, damaged coil, or BSI/ECU communication. Try spare key. Diagnosis: EL50448 antenna, UCH module.
Opel Crossland: diagnostic master plan
EOBD / OBD2
Read global codes. Use ELM327 with Torque or Car Scanner. For manufacturer specific: Diagbox (PSA) or Autel MD808.
Pro-level scanners
Autel MaxiSys, Launch X431, GDS2 (Tech2Win). Access ABS, airbag, EPB, BSI, injector coding, AdBlue reset.
Electrical tests
Multimeter, oscilloscope for crank/cam, pressure transducer for fuel. Check ground points (under battery, gearbox).
Mechanical diag
Compression test, leak-down, coolant pressure tester, smoke machine for evap/vacuum leaks.
