Common Problems with the
1989 BMW M3

Buying Tips for 1989 BMW M3

• ✓On E46 and E90/E92 models, demand proof that the rod bearings have been replaced; failure to do so will result in a destroyed engine.
• ✓On the F80 generation (S55 engine), check if the crank hub has been upgraded or pinned, especially if the car has an aftermarket tune.
• ✓Inspect the boot floor on E46 models for the notorious subframe mounting cracks; this is a guaranteed failure point requiring structural welding.
• ✓Check the electronic damper control (EDC) suspension for leaks; replacement M-specific shock absorbers are eye-wateringly expensive.
• ✓Verify the 1,200-mile running-in service was completed precisely on time, as BMW can deny warranty or goodwill claims if it was missed.
• ✓Examine the carbon fibre roof (if fitted) for peeling clear coat or stone chips, as repairs require specialist carbon fiber work.
