Diagnostics
How we diagnose Polestar engine faults
First we isolate the root cause, then we choose the repair. That avoids unnecessary parts and makes the estimate reliable.
Brand-specific fault-code and live-data check
We start with diagnostics matched to Polestar 2 Single/Dual Motor, Polestar 1 Plug-in Hybrid engines. Fault codes and live data are compared against the symptom so we separate an electrical issue from mechanical damage before ordering parts.
Compression, leak-down and pressure tests
If the symptom points to a fault such as hv charging system issues, we measure compression, leak-down and coolant or boost pressure. That confirms whether the fault is in the head, timing system, piston rings or an ancillary component.
Endoscope and visual inspection
When needed, we inspect the cylinders with an endoscope, check leaks, carbon build-up and crankcase ventilation, then document the findings before you approve the repair.
Repair scope
Polestar engine repair from small faults to full rebuilds
Timing system and valve-train repairs
We repair faults such as software updates by replacing chains, belts, tensioners, guides and required seals as one controlled package.
Oil consumption, smoke and compression repairs
When the fault is in piston rings, valve-stem seals or the head gasket, the repair follows the root cause. We do not mask symptoms with additives; worn parts are repaired or renewed.
Ancillaries, turbochargers and emissions systems
We also diagnose faults such as 12 v battery replacement, EGR, DPF, water pump, turbo and fuel-system issues before recommending an unnecessarily large engine repair.
Repair or replacement engine
Repair is often safer than an unknown replacement engine
A repaired engine is known inside out
A used replacement engine can carry the same model-specific fault as the failed one. In a repair, wear parts, seals and risk points are inspected and documented.
Lower risk when the damage is scoped correctly
After diagnosis we compare repair, partial repair and replacement-engine costs. If an engine swap is the better route, we say so directly.
Warranty on labour and installed parts
The repair uses OE-quality parts and a written estimate. You get a clear repair scope, not just an unknown used component.
Price and scope
Polestar engine repair pricing depends on diagnosis
The starting price is a baseline, not a guess
A full engine rebuild starts from EUR 1,999 on common four-cylinder engines. The final price depends on engine code, damage scope and parts availability.
Individual jobs are priced separately
If a full rebuild is not needed, the cards below show typical engine jobs such as timing belt, head gasket, EGR, turbo and water pump work.
Work starts only after approval
After diagnosis you receive a written estimate. We start only once scope, price and schedule are clear to you.

FAQ
Polestar engine repair — frequently asked
Is Polestar the same as Volvo?
It shares a lot of tech, but Polestar 2 is fully electric and needs EV know-how.
How often should a Polestar be serviced?
Typically every 30,000 km or two years — EV servicing is lighter than for combustion cars.
Can you service the Polestar 1 plug-in hybrid?
Yes, both the electric side and the T8 combustion engine.
