Common Problems
Peugeot iOn Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The Peugeot iOn's electric powertrain is generally robust, but three issues dominate replacement enquiries: Motor Control Unit (MCU) failure on 2011-2012 models, Transmission Control Unit (TCU) faults causing grinding or limp mode, and high-voltage errors often triggered by the 12V auxiliary battery. Every rebuilt motor supplied through EngineMarket...

Root cause
Internal power electronics failure in the inverter module, exacerbated by thermal cycling and known manufacturing defect covered by recall ZZZ.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Diagnostic & Software Reset - Check for fault codes and attempt reprogramming | £150 - £300 | £95 - £200 | OBD2 diagnostic scan, software update attempt | Only viable if failure is software-related; temporary fix for hardware faults |
| MCU Replacement - Reconditioned Unit - Swap faulty control module | £1,200 - £2,000 | £600 - £1,200 | Remove old MCU, install tested reconditioned unit with updated firmware | Restores full function; 12-month warranty covers recurrence |
| Full Drive Unit Replacement - Motor + MCU assembly | £2,500 - £4,000 | £1,500 - £2,500 | Replace entire electric motor and control unit assembly | Most comprehensive solution; recommended for high-mileage vehicles |
Our recommendation
For 2011-2012 iOn models showing MCU-related faults, a reconditioned MCU replacement offers the best value. Given the iOn's low residual value (£2,000-£3,500), spending over £1,500 on repairs warrants careful consideration against vehicle worth.
