All Known Issues

Cracked Alloy Wheels

SeriousSuspension & Chassis

The combination of large 19-inch alloy wheels (especially Style 296 and Style 326M), stiff low-profile run-flat tyres, and rigid M Sport damping causes the inner rim barrel to crack under impact from potholes.

Est. Repair Cost: £100 (Weld) / £400 (New wheel)
Warning Signs:

Slow puncture warning requiring weekly tyre reinflation, Steering wheel or seat vibration at motorway speeds, Hairline cracks visible along the rear inner wheel rim barrel

What to Inspect:
  • Remove wheels or inspect inner barrels with a torch and mirror on a ramp
  • Check if tyres are original run-flats or conventional replacements
  • Verify prior weld repairs on inner rim edges

High Pressure Fuel Pump (35i)

SeriousFuel System

The direct-injection twin-turbo N54 engine in 35i and 35is models features a high-pressure fuel pump (HPFP) that suffers internal mechanical seal and solenoid failure, causing long cranking times and limp-home mode under load.

Est. Repair Cost: £600–£1,000
Warning Signs:

Extended engine cranking time (5–10 seconds) on cold start, Engine malfunction half-power warning light illuminated, Hesitation, stutter, and limp mode during hard acceleration

What to Inspect:
  • Check cold engine start cranking duration
  • Review service receipts for updated Bosch/Continental HPFP part numbers
  • Scan DME for fuel rail pressure drop fault codes (2FBF, 29DC)

Folding Roof Relays/Pump

SeriousBodywork & Rust

The two-piece retractable electro-hydraulic hardtop relies on twin salmon-coloured relays located near the battery. Sticking relay contacts keep the hydraulic pump motor running continuously until it burns out or overheats.

Est. Repair Cost: £50–£1,000
Warning Signs:

Roof operation stalls halfway through opening or closing cycle, Hydraulic motor whines loudly or runs continuously without roof movement, Moisture, standing water, or hydraulic fluid pooling in lower boot battery tray

What to Inspect:
  • Cycle roof through 3 complete open and close cycles without hesitation
  • Check if salmon relays (part no. 12637591534) have been replaced every 3–4 years
  • Inspect boot floor under the battery tray for hydraulic oil leaks
