Citroën C4 X
Stronger turbo variant of the PSA three-cylinder. Same wet belt issue as the EB2-DT in production years before 2019. Punchy mid-range, good compromise between performance and consumption.
Spacious fastback with economical character
The PureTech 130 moves the C4 X with the EAT8 automatic comfortably and economically — real-world tests measure around 4.1 litres per 100 km, better than comparable compact rivals. The Advanced Comfort suspension with progressive hydraulic bump stops delivers a smooth glide; the C4 X has no sporting intentions. 510 litres of boot space and 200 km/h top speed make it a relaxed touring companion.
Engine Weaknesses 6
Oil-bath timing belt delaminates due to fuel dilution of the oil; stop-start operation of the mild hybrid system adds additional belt stress. Newer Gen 3 engines from 2022 feature a revised design.
Symptoms: Oil pressure warning light, engine noises, power drop, potential engine damage
Oil scraper rings coke up from short-trip use with direct injection; engine can consume up to 3 l/1,000 km. Stellantis offers extended goodwill up to 175,000 km for build years before 2022.
Symptoms: Elevated oil consumption, blue smoke on throttle, frequent oil checks needed
Higher boost levels increase thermal stress; fuel-diluted engine oil reduces lubricity and damages the turbo journal bearings. Warning signs are often not detectable in advance.
Symptoms: Whistling or rattling turbo noise, bluish exhaust smoke, power drop
The EB2-DTS 1.2 Turbo 130 shares with all EB2 engines the problem of crankshaft bearing end-float wear. Excessive axial play causes the timing belt to shift sideways and increases the risk of belt failure.
Symptoms: Axial clicking on throttle changes, oil pressure warning, belt debris visible in oil, in extreme cases sudden belt failure
Like all turbocharged EB2 variants, the EB2-DTS 130 is prone to fuel contamination of engine oil during short-trip operation. The consequences are timing belt damage, bearing wear, and oil pump problems.
Symptoms: Petrol smell in oil, oil level rises above maximum, thin oil, occasional oil pressure warning
EB2-DTS engines were fitted with vacuum pumps containing manufacturing defects. Faulty pumps can lead to insufficient brake servo supply. Stellantis treated approximately 370,000 vehicles with turbocharged EB2 engines (March 2013 – April 2017) with a pump replacement.
Symptoms: Firmer brake pedal feel, delayed brake system response, reduced brake assist, occasional brake system warning messages
Vehicle Weaknesses 4
Like other C4 models, C4 X owners report rapidly wearing brake discs. The braking system is a known weak point across this generation of Citroën/PSA compact cars.
The MY-Citroën infotainment system on the C4 X shows occasional crashes and faulty Bluetooth/smartphone connections. Remote functions of the Citroën app only work with limited reliability.
Defects in electrically folding door mirrors are reported on the C4 X. Corroded contacts or failed mirror motors prevent folding — a typical problem on Citroën models of this platform.
C4 X owners report that the air conditioning does not cool sufficiently in high outside temperatures. The A/C is a known problem area on PSA compact models; compressor and refrigerant leak are the causes.
