If the electric power steering becomes heavy, chances are the Koyo ECU has developed a fault (it’s indicated by the fault code ‘C1554’). If you’re buying secondhand, it’s easier to replace the whole column (from around £60), otherwise the ECU can be repaired by the likes of BBA Reman for around £175.
Being such a light car – it weighs just 820kg – suspension components last well. However, tyre wear has been an issue, as have noisy wheel bearings – they don’t seem to last very long on the Aygo.
