Steering column (universal intermediate shaft bushings)
Poor-quality bushings in the sealed steering column wear out, causing play and noise.[4] · Typical repair: £400-£700 (full column replacement at indie).
Horn wiring in steering wheel
Faulty wiring chafes, shorting intermittently.[1] · Typical repair: £80-£150 (rewire/insulate at indie, estimated).
Gear selection (5MX65 5-speed manual gearbox linkage)
Worn selector mechanism or cable adjustment fails, preventing 1st/reverse engagement.[1] · Typical repair: £200-£400 (linkage adjust/replace at indie).
M1DA
Faulty sensor signal with voltage drops/spikes, misinterpreted by ECU as extra crank counts, causing misfires or injector cut-out. Likely poor contact at sensor socket or 5V reference supply vibration.
