BMW E31 8 Series

Chassis guide

BMW E31 parts — what fails, and what we reproduce

Commonly unavailable parts

• Interior door pulls and handle cups

  Typical failure — The plastic behind the mounting clips goes brittle with age and heat, then splits the first time the door is pulled hard. Cracks usually start at the screw boss rather than the visible face.

  MMG approach — Reproduced with thicker material around the boss and clip lands, so the reinforced area sits where the original failed while the visible surface keeps the factory profile and grain.

• Seat switch bezels and console switch surrounds

  Typical failure — Retaining tabs snap off, leaving the switch pack loose in the panel and rattling over expansion joints.

  MMG approach — We rebuild the tab geometry from an intact original and check the switch pack clicks home with the correct retention before the part ships.

• Headlight and front-end trim components

  Typical failure — Sun exposure embrittles trim and mounting lugs; a part that looks intact will often shear at the lug during removal.

  MMG approach — Produced in a UV-tolerant material with a matte finish, and dimensioned against the original mounting points rather than the deformed used part.

• Centre console and shifter surround panels

  Typical failure — Warping and shrinkage around the shifter aperture, plus stress cracks at the fixing points on high-mileage cars.

  MMG approach — Reproduced as a full panel so the aperture and every fixing point stay in the same relationship as the factory moulding.

• Mirror covers and exterior trim caps

  Typical failure — Colour fade and cracked clips; matching an aged painted finish is usually harder than making the part.

  MMG approach — Supplied ready for paint so a body shop can colour-match to your car rather than to a factory code that no longer matches a 30-year-old panel.

• Interior brackets, clips and retainers

  Typical failure — Small hidden components that fail during a trim removal and stop a reassembly dead, because no supplier lists them individually.

  MMG approach — Made to order from the broken original — this is the most common E31 custom request we receive, and usually the quickest to turn around.
