Engine / equipment
115 hp 1.6 VTi (EC5, a development of the TU5): Peugeot 301 and Citroën C-Elysée
Period mentioned
2012–2018
Symptoms
Oil has to be topped up between changes; oil stains under the engine; misfires or hesitation; rough idle or an engine warning from the throttle body.
Possible cause described
This 1.6 VTi is not the BMW-designed (Prince) VTi but the EC5, derived from the long-serving TU5. The AutoCentrum.pl engine encyclopedia (2022) rates it durable and cheap to run, but says owners often complain of high oil consumption, that an ignition coil or the throttle body sometimes fails and that oil leaks can be the biggest problem; early engines had ignition faults linked to poor servicing.
Check for the garage
Measure oil consumption between two changes and look underneath for leaks; read misfire and throttle-body codes; ask for the timing-belt invoices.
