How much does a BMW X1 25e / 30e engine replacement cost in the UK?

A reconditioned X1 25e/30e (B38) engine typically costs £3,500–£5,500 supply only. Fitting adds £2,000–£3,000 depending on location and workshop rates. A blown engine can cost £7,000–£12,000 to replace. Use our calculator for a figure specific to your car.

What are the common problems with the X1 25e / 30e?

The main known issues are: (1) 'Antrieb gestört' drivetrain malfunction -a well-documented issue on U11 PHEV models, (2) Hybrid battery and charging problems -faulty charging ports or battery degradation, and (3) Timing chain tensioner wear -causing cold-start rattle on the B38 engine.

Is it worth replacing an X1 25e / 30e engine, or should I scrap the car?

Depends on vehicle value and condition. Against a well-kept £20,000–£35,000 X1 PHEV, a £4,500–£6,500 recon is 15–30% of the car's value -worth it given the X1's strong retained values. However, if the hybrid battery also needs replacement (£3,000–£6,000+), evaluate total repair costs against the vehicle's value.

How do I find my BMW X1 25e / 30e engine code?

The X1 25e/30e uses the B38A15 family. F48 generation (2020–2022, 25e only) uses B38A15A. U11 generation (2022–present, 25e and 30e) uses B38A15M0. The engine code is stamped on the cylinder block. Tell us your registration and we'll confirm it for free.

Does the B38 have timing chain issues?

While the B38 is significantly more reliable than the N47 diesel and earlier N-series petrol engines, timing chain tensioner wear is still documented. Symptoms include rattling or clattering noises from the engine on cold start. BMW recommends regular oil changes using the correct BMW-approved oil to minimise wear. At the first sign of cold-start rattle, book an inspection immediately.

Common Problems With BMW 320d Engines

1. "Antrieb gestört" -Drivetrain Malfunction Warning (U11 PHEV)

Symptoms: "Antrieb gestört. Weiterfahrt möglich" or "Antrieb gestört, Weiterfahrt nicht möglich" message on dashboard, loss of hybrid drive, reduced power, vehicle may not start or may stall

Typical mileage: Can occur from new -reported on vehicles with only a few weeks of age

Repair cost: £200–£1,500 (diagnosis + software update / component replacement)

Replacement cost: N/A -repair only (does not progress to engine replacement if addressed)

🟠 Check - book inspection urgently if warning appears

Our recommendation:

The "Antrieb gestört" (drivetrain malfunction) warning is a well-documented issue on the U11 X1 PHEV. One owner reported their 25e stranded at a petrol station with the message. Another reported the same issue on a weeks-old 30e. The fault can range from a software glitch to a more serious hybrid component failure. If this warning appears, have the vehicle diagnosed immediately. Some cases require software updates; others may need hybrid component replacement. Do not ignore this warning -it can leave you stranded.

2. Hybrid Battery & Charging Issues

Symptoms: Slow or no charging, reduced electric range, battery not holding charge, "charging error" messages, 12V battery drain

Typical mileage: Any mileage -can occur from new

Repair cost: £300–£800 (charging port / cable replacement) / £3,000–£6,000+ (battery replacement)

Replacement cost: N/A -repair only (does not progress to engine replacement if addressed)

🟡 Monitor - book inspection if charging problems develop

Our recommendation:

BMW hybrids can suffer from battery and charging issues. Some hybrids fail to charge properly due to faulty charging ports, cables, or battery issues. The U11 generation uses a 14.2 kWh lithium-ion battery. Symptoms include slow or no charging and reduced electric range. If you experience charging problems, have the charging components inspected. The high-voltage battery is expensive to replace -check if the vehicle is still under the BMW battery warranty (8 years / 100,000 miles in many markets).

Read the full hybrid battery guide

3. Timing Chain Tensioner Wear (B38 Engine)

Symptoms: Rattling or clattering noise from the engine on cold start, rough idling, engine misfires, check engine light

Typical mileage: 60,000–100,000 miles -less common than N-series engines but documented

Repair cost: £800–£1,800 (chain tensioner, guides and chains)

Replacement cost: £4,500–£8,500 (if chain snaps -full engine replacement)

🔴 Immediate - if you hear rattle on cold start, book an inspection today

Our recommendation:

While the B38 is more reliable than the N47 diesel, timing chain tensioner wear is still a documented issue on B38 engines. Symptoms include metallic rattling noises on cold start, rough idling and engine misfires. The timing chain can stretch over time due to wear and tear, affecting the engine's timing. At the first sign of cold-start rattle, get the chain inspected immediately. A £800–£1,800 preventative repair is dramatically cheaper than a £4,500–£8,500 engine replacement.

Buying This X1 25e / 30e? Check These First

Buy If

Full service history with BMW-approved oil changes
Remaining manufacturer warranty -PHEV systems are complex and benefit from cover
Documented software updates applied -especially for drivetrain issues
U11 generation (2022+) with larger 14.2 kWh battery and improved range

Avoid If

"Antrieb gestört" warnings without documented fix -this is a known U11 issue
Charging problems or reduced electric range -could indicate battery issues
No service history -the B38 is reliable but needs proper maintenance
Cold-start rattle -this is a warning sign of timing chain tensioner wear

Closing Verdict

The X1 25e and 30e are BMW's plug-in hybrid compact SUVs, sharing the same 1.5-litre three-cylinder B38 petrol engine with different electric motor outputs. The 30e delivers an impressive 326 hp and 0-60 in 5.6 seconds. The B38 engine is generally robust and more reliable than the N-series engines that preceded it. However, the PHEV system has documented issues -"Antrieb gestört" drivetrain warnings and charging problems. Buy with full service history and remaining warranty, and you'll have a refined and efficient plug-in hybrid SUV. Without history? Proceed with caution -hybrid repairs can be expensive.
