BMW 2 Series M240i Engine Replacement Compare Prices & Get Quotes

A BMW 2 Series M240i engine replacement typically costs between £2,800 and £5,200 depending on the condition (used, reconditioned, or rebuilt) and the specific engine code. Used engines start from around £1,800, reconditioned units from £2,800, and fully rebuilt engines with a 12-month warranty from £3,000. Labour for supply and fit adds approximately £800-£1,500 depending on the workshop. Main dealer replacement costs can exceed £4,200.

• Used: £1,800-£2,800
• Reconditioned: £2,800-£4,200
• Rebuilt: £3,000-£5,200

The most common symptoms are coolant loss without visible external leaks, oil contamination (milky appearance), and a sweet smell from the engine bay. The B58's plastic oil filter housing is prone to cracking, which can lead to oil and coolant mixing - a known potentially catastrophic problem. If left unchecked, this can cause bearing failure and engine seizure.

• Coolant loss is the primary symptom
• Oil may appear milky (coolant contamination)
• Ignoring it can lead to catastrophic engine failure

It depends on the vehicle's value and the extent of the damage. For an F22 M240i (2017-2021) worth £18,000-£28,000, a reconditioned engine at £2,800-£3,800 is often worthwhile if you plan to keep the car. For G42 models (2021+) worth £25,000-£45,000, replacement is almost always justified. If the car is worth under £5,000, a used engine or repair may be more cost-effective.

• Vehicle value is the key deciding factor
• Rebuilt engines come with a 12-month warranty for peace of mind
• Compare quotes to find the best value option
