The 1.2 PureTech turbo engine is still causing lots of trouble for its owners. At issue is premature
degradation of the engine oil, which leads to timing belt wear – a problem already discussed in
connection with the naturally aspirated version.
But in the turbo version, when the timing belt disintegrates, the residue gradually contaminates the
engine oil and can potentially plug the vacuum pump, the variable valve timing solenoids, or the
(filter) screen of the oil pump.
There are several adverse impacts: if the vacuum pump plugs up, the power brake system fails,
which is no small problem, as you can imagine. Braking then requires tremendous force on the
brake pedal. These engines have also experienced lubrication issues (loss of oil pressure) or
camshaft and valve fouling.
As a result, a safety recall has been issued.
The recalled vehicles include all Peugeot (recall code JZR), Citroën and DS (recall code HFC)
models equipped with the 1.2 Puretech 110 hp or 130 hp engine and manufactured between
March 2013 and April 2017.
The source of the problem relates to the rapid degradation of engine oil, primarily in vehicles
operated relatively infrequently (less than 15,000 km per year) and where the vast majority of that
usage involves city driving. Under these usage conditions, the 1.2 PureTech is susceptible to oil
dilution, whereby fine droplets of unburnt fuel slide down the cylinder walls and mix with the oil in
the pan below. The resulting mixture turns out to be abrasive for the belt – and this explains the
wear. In the absence of a technical solution that prevents this condition, the only way to protect the
belt on these infrequently used cars is to change their engine oil annually. Which explains why the
manufacturer recommends verifying the condition of the belt via the oil fill port during every routine
maintenance. Basically, when topping up the oil, you pour it into a hole situated over the timing belt.
Through that same hole, you can see part of the belt and this lets you determine its condition.
The belt should be inspected (belt width check) using a timing belt checking gauge at three
different points (crankshaft rotation).
Timing belt checking gauge
OE (G-0109-6)
NOTE: The replacement interval for the timing belt is now 100,000 km or 6 years.
KD459.70 /06-2022
Belt width must be checked.
If the belt width does not meet the specification, the lower oil pan must be removed to inspect the
oil pump screen.
➢ The belt need not be replaced unless it does not meet the specification. If it does require
replacement, the vacuum pump must also be replaced.
➢ If the oil pump screen is slightly plugged, it must be cleaned; the oil pump solenoid valve must
be replaced; the variable valve timing solenoid valves can either be cleaned or replaced; the
hollow screw of the oil supply line to the turbo must be replaced; and of course the vacuum
pump and the complete engine valve timing system must be replaced.
➢ If the screen is completely plugged, the oil pump must also be replaced.
And in all cases, the engine control unit must be reprogrammed to – as the recall notice
states – "update the engine control unit for the purposes of improving the power brake
system diagnostics and to eliminate any risk of reduction or loss of braking function."
In other words, the car will illuminate the oil pressure loss indicator on the instrument panel
earlier to show that there's a problem.

Recommendations
Turn the engine only by rotating the crankshaft pulley in the direction of operation.
Do not rotate the crankshaft or the camshafts while the timing belt has been removed.
Make timing belt adjustments only while the engine is cold.
It is recommended not to reuse accessory belts after removal: always replace them instead.
