P2263 on Volvo by model: symptoms, diagnosis and fix
The turbocharger on the XC70 2.5T (B5254T2) and T6 (B6304T4) engines develops wastegate rattle and eventual turbo failure. The wastegate actuator rod and pivot bushing wear, causing a rattling sound on cold start and under light boost. The turbo bearings also fail from oil coking (oil baked onto the bearing surface from heat-soak after shut-off) and PCV-related oil supply issues. The P2 platform XC70 (2001-2007) uses a Mitsubishi TD04 turbo, while the P3 platform (2008-2016) uses a Borg Warner BV50 or TD04L. Both are prone to failure with similar symptoms.
Common Symptoms
- Rattling noise from turbo area on cold start
- Rattling under light acceleration that disappears at full boost
- Blue smoke from exhaust under acceleration
- Loss of boost pressure
- Check engine light with overboost or underboost codes
- Oil in intercooler piping
How to Fix
For wastegate rattle only, the wastegate actuator can be replaced or adjusted without replacing the entire turbo (Volvo part 36012387 for actuator on P3 models). For turbo bearing failure, replace the complete turbo assembly (Volvo part 36002369 for P2, 36012488 for P3). Replace oil feed and return lines. Fix PCV system if contributing to oil starvation. Use quality synthetic oil and let engine idle 30 seconds before shutdown after hard driving to prevent oil coking.

Frequently asked questions
What does P2263 mean on a Volvo?
P2263 stands for "Turbo/Supercharger Boost System Performance." This code means the computer has detected that the turbocharger or supercharger boost system is not performing as expected, even though no single sensor circuit has failed. The computer compares the actual manifold boost pressure against the target it commanded and sets this code when they don't match for a sustained period. You may notice low power, sluggish acceleration, or limp mode. It signals an overall boost shortfall and usually points to leaks, a failing turbo/charger, or a control component rather than a specific wiring fault. On Volvo it is documented across 1 model: XC70.
What are the most common causes of P2263?
The most common causes of P2263 are: Boost/intake leak in piping, hoses, or couplers, Failing turbocharger or supercharger, Stuck or faulty wastegate or boost control actuator, Faulty boost/MAP pressure sensor, Clogged or damaged charge air cooler (intercooler), Sticking variable-vane (VGT) mechanism on diesels, Faulty boost control solenoid or vacuum supply, Restricted air filter or intake restriction. The specific cause varies by vehicle.
How much does it cost to fix P2263 on a Volvo?
Published repair estimates on Volvo range from $300 to $3,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
