From Gearbox Failures to Electrical Issues, MT Auto Parts Provides Affordable BMW Parts

When your BMW starts slipping gears or throws an electrical fault, the dealer quote can be enough to make you question keeping the car at all. In the UK, average BMW repair costs are among the highest of any mainstream manufacturer, with gearbox replacements often stretching well over £5,000 at main dealers. Add to that the rise of electrified BMWs with hybrid batteries and complex ECUs and the bills keep climbing.

That’s why garages and private owners alike are increasingly turning to BMW breakers such as MT Auto Parts — specialists in supplying BMW parts at a fraction of dealer prices.

Why used BMW parts are changing the game in the UK

The appeal is straightforward: every component sourced from a donor car is still an original BMW part, but offered at 50–70% less than a brand-new equivalent in dealerships. Add in mileage disclosure, warranty coverage and quick shipping across the UK and the argument for second-hand has never been stronger.

The reality of dealer pricing

• Automatic gearbox faults quoted at £5,000–£6,500.
• Hybrid battery failures priced at £4,500+.
• ECUs and charging modules often cost £2,000 or more.

Against that backdrop, dismantlers make complex BMW repairs financially viable again.

Affordable gearbox replacements

Tested and warranted units

Gearboxes remain one of the most common (and expensive) BMW repairs. At MT Auto Parts, every unit is tested and sold with warranty, giving garages the confidence to fit them straight away.

Examples include:

• BMW M5/M6 dual clutch gearbox (GS7D70SG) – between £1,700–£2,100, compared with £5,000+ from new.
• BMW X3M/X4M GA8X76AZ 8-speed auto – typically £2,400–£2,600.
• BMW 3 Series hybrid automatic gearbox (8HP75HZ) – often available for £2,000–£2,400, ideal for plug-in hybrid models.

For garages, these numbers can be the difference between quoting a repair that gets approved or losing the customer to a write-off.

Electrical and hybrid components made affordable

Modern BMWs depend on complex electrical systems — and when they fail, the costs can increase engine repairs highly. MT Auto Parts carefully dismantles newer donor cars and BMW accessories that would otherwise be prohibitively expensive.

High-voltage hybrid batteries

• BMW X5 G05 45e hybrid battery – around £1,799, instead of £5,000 from the dealer.
• BMW 3 Series G20 330e hybrid battery – near £900, helping keep plug-in 3 Series affordable to maintain.

Charging and inverter modules

• BMW i4 Series combined charging unit (G26) – anywhere from £750–£1,700, depending on model year.
• BMW 5 Series comfort charging module (G30) – often around £700, well below new dealer prices.

ECU and control units

• BMW 1 Series ECU (F70) – around £1,000.
• BMW M5 ECU (F90 Competition) – listed near £750.
• BMW 6 Series multifunctional speedometer display – at £700.

All of these give major saves, over new dealership prices.

Why garages and owners trust dismantlers

Genuine OEM fitment

All BMW parts are taken from BMW donor vehicles, meaning that most of the parts are genuine BMW components, no aftermarket auto parts.

Warranty-backed confidence

From gearboxes to hybrid batteries, warranties are included, giving peace of mind for both workshops and customers.

Nationwide delivery

With 24–48 hour shipping available, downtime is cut short and cars are back on the road faster.

Final thoughts
