Buying This BMW X5 xDrive45e? Check These First
Buy if:
- Full BMW service history with documented battery health checks
- Recent software updates applied (PCM, BMS, TCU)
- Low-mileage with documented charging history (AC charging preferred)
- Still under the 6-year/100,000-mile battery warranty (check transferability)
- Cooling system history -water pump and expansion tank checked
Avoid if:
- Significant reduction in electric-only range (battery degradation warning)
- Any hybrid system warnings or drive mode malfunctions without a documented fix
- Poor charging history (frequent rapid charging or deep discharges)
- Missing service history -the PHEV system is complex and unforgiving
- Poor service history on the combustion engine -the B58 is robust but needs proper oil
Closing verdict
The xDrive45e is a landmark plug-in hybrid -combining BMW's excellent B58 inline-six with a powerful 105kW electric motor for 394bhp of seamless performance. The combustion engine is the proven B58, while the 24kWh battery offers genuine electric range. Battery health is the long-term question mark -buy on documented history, charge it properly, and this is a genuinely compelling plug-in hybrid SUV.

Buying Checklist
Before you buy a used BMW X5 xDrive45e (or before you commit to a powertrain replacement), check these:
1. Battery Health -Check the estimated electric range; any significant drop from the 54-mile (WLTP) claim?
2. Charging History -Has the vehicle been charged correctly? Frequent rapid charging can degrade batteries
3. Cold Start -Listen for any rattle on startup (B58 should be smooth)
4. Service History -Must show hybrid system checks; 8,000–10,000 mile oil changes are essential
5. Coolant Level -Check for any loss -water pump and expansion tank are key risks
6. PCV System -Any whistling from the engine? Increased oil consumption?
7. Hybrid System -Check all drive modes work; any warning lights or messages?
8. Engine Warning Light -Have codes been read? Hybrid system codes are common

Frequently Asked Questions
A reconditioned BMW X5 xDrive45e powertrain (B58B30 + e-motor) typically costs £6,500–£10,000 supply only. Fitting adds £1,500–£2,200. Hybrid system work requires specialist training. Battery replacement is a separate cost -approximately £8,000–£12,000.
The xDrive45e combines the proven B58 3.0-litre inline-six with a 105kW electric motor and 24kWh battery. The combustion engine is well-developed and reliable, with cooling system leaks as the main concern. The hybrid system adds complexity, but early owner reports indicate strong reliability. Battery health is the long-term question mark -all lithium-ion batteries degrade over time.
PHEV battery degradation (reduced electric range, £8,000–£12,000 replacement), cooling system leaks on the combustion engine (water pump, expansion tank, £400–£1,000), PCV valve/oil separator failure (whistling, oil consumption, £400–£800), and hybrid system software issues (drive mode malfunctions, warning lights, £150–£500 software update).
X5 xDrive45e values range from £30,000–£60,000 depending on year, condition and mileage. A £6,500–£10,000 reconditioned powertrain represents 10–30% of vehicle value -well within our 70% BMW scrap threshold. For most examples, replacement is financially viable. Battery replacement at £8,000–£12,000 is a separate consideration.
The xDrive45e uses the B58B30 engine code -BMW's 3.0-litre inline-six -combined with a 105kW electric motor. This is the same engine as the 40i but with additional hybrid hardware. The total system output is 394bhp. The code is stamped on the engine block; your VIN and vehicle documentation will also confirm the specification.
In many cases, individual battery modules can be replaced (£2,000–£4,000 per module) rather than the entire pack (£8,000–£12,000). A BMW specialist can perform a battery health check to determine which cells have degraded. At the first sign of significant range reduction, book a health check. Regular AC charging (rather than rapid DC charging) and avoiding deep discharges help preserve battery life.
