P0175 on Your 2024 Volvo XC60: What It Means
The 2024 Volvo XC60 features the refined Drive-E 2.0L four-cylinder in B5 (mild-hybrid turbo, 247 hp) and B6 (mild-hybrid turbo + supercharged, 295 hp) variants, plus the T8 Recharge plug-in hybrid. When P0175 appears, the ECM has detected a persistent rich-running condition that it cannot correct through standard fuel trim adjustments. The system is delivering more fuel than the engine needs for optimal combustion.
Symptoms to Look For
- Check engine light illuminated
- Noticeable fuel economy decrease
- Dark exhaust smoke, especially on cold starts
- Unsteady idle
- Fuel smell from the exhaust
- Possible performance reduction message on the driver display
What Causes P0175 on the 2024 XC60
1. MAF Sensor Contamination — High Likelihood
The Bosch hot-film MAF sensor in the XC60's intake tract is the most common source of rich-running codes on Drive-E engines. Even on a new 2024 model, installation of an oiled aftermarket air filter or exposure to unusual conditions can contaminate the sensor. The 48V mild-hybrid system doesn't affect this — the combustion engine's fueling is still controlled by the MAF input.
2. Oxygen Sensor Malfunction — Medium Likelihood
The upstream wideband O2 sensor monitors exhaust gas composition in real time. On the 2024 XC60, a manufacturing defect could cause early failure, reporting falsely lean readings that prompt the ECM to add unnecessary fuel. This sensor is positioned near the turbo outlet in a very hot environment.
3. Fuel Injector Issue — Medium Likelihood
High-pressure direct injection (2,500+ PSI) is standard on all Drive-E variants. A defective injector on a new vehicle would be a manufacturing flaw — the injector may not seat properly or may have a tolerance issue that allows excess fuel delivery.
4. ECM Software Calibration — Low Likelihood
Volvo periodically releases software updates for the ECM that refine fuel maps and sensor interpretation. On a 2024 model, a software update or TSB (Technical Service Bulletin) may address P0175 without any hardware replacement needed.
Diagnostic Steps
- Dealer TSB check — First step should be checking for any active Technical Service Bulletins addressing P0175 on the 2024 XC60.
- Fuel trim analysis — STFT and LTFT values using VIDA diagnostics. Values above +15-20% confirm the rich condition.
- MAF sensor inspection — Check for contamination. If an aftermarket air filter is installed, return to OEM.
- O2 sensor test — Monitor response time and signal accuracy using VIDA's graphing capabilities.
- Injector performance test — VIDA can run cylinder-specific contribution tests.
Costs and Warranty Coverage
The 2024 XC60 is covered by Volvo's 4-year/50,000-mile new vehicle limited warranty:
- MAF sensor cleaning: $10–$15 (DIY, but consider warranty)
- MAF sensor replacement: $250–$450 (warranty covered)
- O2 sensor replacement: $300–$550 (warranty covered)
- Fuel injector replacement: $350–$650 (warranty covered)
- Software update: $0 (warranty covered)
Go to the Dealer
On a 2024 model under warranty, the correct move is taking the XC60 to your Volvo dealer. They have VIDA diagnostics, access to TSBs, and can perform warranty repairs at no cost to you. DIY troubleshooting on a warranty vehicle can sometimes complicate coverage claims.
Driving Safety
You can drive to the dealer without concern. Avoid heavy loads and aggressive driving, as the rich condition creates additional heat that can stress the close-coupled catalytic converter. The XC60's converter runs $2,000–$3,500 to replace, so timely warranty service protects against that potential expense.
