Diagnostics

How we diagnose Citroen engine faults

First we isolate the root cause, then we choose the repair. That avoids unnecessary parts and makes the estimate reliable.

Brand-specific fault-code and live-data check

We start with diagnostics matched to 1.2 PureTech, 1.6 THP, 1.6 HDi, 2.0 HDi engines. Fault codes and live data are compared against the symptom so we separate an electrical issue from mechanical damage before ordering parts.

Compression, leak-down and pressure tests

If the symptom points to a fault such as 1.6 thp carbon deposits, we measure compression, leak-down and coolant or boost pressure. That confirms whether the fault is in the head, timing system, piston rings or an ancillary component.

Endoscope and visual inspection

When needed, we inspect the cylinders with an endoscope, check leaks, carbon build-up and crankcase ventilation, then document the findings before you approve the repair.

Repair scope

Citroen engine repair from small faults to full rebuilds

Timing system and valve-train repairs

We repair faults such as hdi eolys system issues by replacing chains, belts, tensioners, guides and required seals as one controlled package.

Oil consumption, smoke and compression repairs

When the fault is in piston rings, valve-stem seals or the head gasket, the repair follows the root cause. We do not mask symptoms with additives; worn parts are repaired or renewed.

Repair or replacement engine

Repair is often safer than an unknown replacement engine

A repaired engine is known inside out

A used replacement engine can carry the same model-specific fault as the failed one. In a repair, wear parts, seals and risk points are inspected and documented.

Lower risk when the damage is scoped correctly

After diagnosis we compare repair, partial repair and replacement-engine costs. If an engine swap is the better route, we say so directly.

Warranty on labour and installed parts

The repair uses OE-quality parts and a written estimate. You get a clear repair scope, not just an unknown used component.

Price and scope

Citroen engine repair pricing depends on diagnosis

The starting price is a baseline, not a guess

A full engine rebuild starts from EUR 1,999 on common four-cylinder engines. The final price depends on engine code, damage scope and parts availability.

Work starts only after approval

After diagnosis you receive a written estimate. We start only once scope, price and schedule are clear to you.
