3.0L S58 - M3 Competition
Petrol
Test drive task: Perform several low-speed, full-lock turns in a parking lot. | Description: Listen for any clicking or binding sounds from the front end, as the complex suspension geometry on the G20 M3 can occasionally exhibit minor noise that warrants an inspection of the control arm bushings.
Check this by: Cycling through all M-Drive modes on a smooth road. | Description: Ensure the adaptive dampers adjust noticeably between Comfort and Sport Plus, as any electronic fault in the damper system can be costly to rectify given the sophisticated nature of the M-suspension.
While parked: Check the alignment of the front bumper and bonnet gaps. | Description: These performance models are often driven enthusiastically; checking body panel gaps can offer clues about whether the vehicle has experienced minor bumper scuffs or front-end impacts in its past.
Test drive task: Execute a few firm, controlled stops from moderate speed. | Description: Pay close attention to any shudder through the steering wheel, as the large M-compound brake discs are high-performance parts that can be sensitive to uneven pad deposits if not bedded in correctly.
Time to inspect brake pad wear and assess the condition of the performance tyres.
Consider a full differential oil service and an inspection of the cooling system hoses.
A common point to check the health of the suspension bushings and verify spark plug service history.
Verify that the engine oil has been changed at least every 10,000km, as the S58 engine thrives on fresh, high-quality synthetic lubricants.
Confirm the brake fluid has been flushed, as moisture accumulation can affect the sensitive M-braking system responsiveness.
Inspect the front and rear wheel arches for excessive stone chipping, which is common on these wide-track models.
Check the iDrive system for any stored shadow codes or service messages that might indicate an intermittent electrical sensor fault.
Ensure all recall campaigns have been addressed through a local BMW service centre using the vehicle's VIN.
Estimated repair costs if issues arise
Given the stopping power of the M3 Competition, the braking components are high-performance items. Depending on your driving style, you might eventually need to budget for a full set of OEM discs and pads.
The S58 engine operates at high temperatures to maximize efficiency. It is wise to set aside funds for cooling system maintenance, such as checking the electric water pump or radiator hoses, as the car ages.
These dampers are electronically controlled for precision handling. If one begins to weep or fails to communicate with the ECU in the future, replacing them is a significant job that ensures the car maintains its factory handling characteristics.
