Check engine (MIL) P‑codes
🔍 Issue:ECM detects emission/reduced power fault. Over 200 possible DTCs. Grandland specific: P20EE (AdBlue), P049B (EGR), P0420 (cat), P0171 (lean).
⚠️ Symptoms:
- Amber light steady/flashing (misfire).
- Loss of power, reduced acceleration.
- Fuel smell, rough idle, increased consumption.
- Sometimes no noticeable symptoms – silent code.
🔧 Diagnosis (advanced):
- 1. Professional scan: Autel/Foxwell with PSA software. Read global OBD + manufacturer specific.
- 2. Check freeze frame data – rpm, load, temp at fault.
- 3. Grandland 1.2 PureTech: inspect timing belt condition (wet belt degradation).
- 4. 1.5/2.0 CDTI: EGR cooler leaks, swirl flap faults.
- 5. Fuel pressure test (high pressure pump on HDi).
- 6. Smoke test for vacuum/intake leaks.
- 7. Check software level – many Grandland need ECU reflash for false P0420.
💰 Repair cost:$85 – $1250 (diagnostic $85–$150, O2 sensor $180, EGR valve $420, cat $950+, timing belt $1100 with labor)
More Grandland data: 2018‑2020 1.6 CDTI: P20EE often requires AdBlue injector replacement + tank cleaning. 2021+ 1.2 PureTech: excessive oil consumption triggers cat damage – extended warranty in some regions.
