Buying Tips for the 2010 Citroën C4 (Mk2)

✓Be wary of 1.6 THP petrols without proof of timing-chain work and short oil-change intervals
✓On later 1.2 PureTech models, inspect the timing belt through the oil filler and check for recall R/2020/331 history
✓If it has the EGS or ETG automated manual, make sure you can tolerate the shift quality and verify it is not slipping or hunting for gears
✓Check front suspension top mounts and drop links carefully because comfort-biased C4s still wear them on UK roads
