Main product description

Vacuum valve / pressure converter 9665886280 9801887680 (PSA 1618.KC) for Citroen and Peugeot cars. It is used to control the vacuum actuators – typically the regulation of the turbocharger (VGT/wastegate) and intake flaps. This is a used, fully functional part with a functionality guarantee. An ideal solution for repairs where you want to maintain the correct behavior of the turbo and intake control while keeping the load on the ground.

Why this part
– Verified used part with tested functionality
– Correct PSA parameters and connector – plug & play
– Frequent cause of turbo regulation errors – quick correction of defects such as loss of power, pressure fluctuations, emergency mode

Typical usage and compatibility
– Citroen and Peugeot cars with HDi and e-HDi engines (often 1.6 HDi DV6, sometimes 2.0 HDi) with vacuum control of the turbo and intake flaps.
– Commonly installed in models such as C3, C4, C5, Berlingo, DS3/DS4; Peugeot 207, 208, 301, 307, 308, 407, 508, 2008, 3008, 5008, Partner, etc.
Note: Always verify the match against the part number on your original valve or VIN before ordering.

Part numbers / designations for searching
– PSA: 1618KC / 1618.KC
– OEM: 9665886280, 9801887680
– Equivalent names: “electrovalve vacuum”, “turbo pressure converter”, “vacuum valve turbo/intake valve”
(If you search by number, at least one of the above must match.)

Technical information
– Type: electromagnetic vacuum valve (3-way)
– Power supply: 12 V, 2-pin PSA connector
– Connection: 3 outlets for vacuum tubes (usually Ø 4–5 mm) – vacuum inlet, actuator outlet, ventilation
– Function: vacuum switching/regulation for VGT/wastegate control of the turbocharger and intake flaps according to the instructions of the control unit
– Location: engine compartment (near the turbo/intake tract; specific position according to the model)

Condition and packaging
– Used part, tested, functionality guaranteed
– Supplied as valve itself (without tubing and brackets unless otherwise stated)

Symptoms of a faulty valve
– Loss of power, erratic acceleration, emergency mode
– Turbo pressure control/intake flap control error codes
– Audible “click” with no actuator response or vacuum leak

Installation recommendations
– Replace cracked vacuum hoses and check check valves
– Connect the tubes according to the port markings (VAC/OUT/VENT) – the confusion will cause incorrect regulation
– After assembly, delete the errors in ŘJ and perform a test drive; in some cars, a reset will help by adapting the turbo regulation

Are you looking for a reliable original vacuum valve for PSA cars? This used, fully functional solenoid valve controls the vacuum for controlling the turbocharger (wastegate/VTG), EGR valve or vacuum actuators. It’s a common source of trouble for HDi engines – a faulty piece causes power fluctuations, idle, erratic boost and P0234/P0243 type fault codes. The exchange is plug & play.

Key benefits
– Original PSA part – correct function and long service life
– Verified by OEM numbers: 9665886280, 9801887680, 1618.KC
– Fits many Citroën and Peugeot models with HDi engines (eg 3008 I, 5008 I – always check against VIN/OEM number)
– Quick assembly without the need for programming

Technical information
– Type: vacuum control solenoid valve (solenoid)
– Power supply: 12 V, 2-pin PSA electrical connector
– Vacuum connection: 3 outlets (vacuum – actuator – vent; tube diameter approx. 3–4 mm)
– Function: modulation of vacuum according to the requirements of the engine control unit for the regulation of boost pressure/EGR
– Mounting: on the holder in the engine compartment (location varies by model and engine)

Compatibility and Use
– Peugeot 3008 I, 5008 I and other Peugeot/Citroën models with 1.6 HDi and 2.0 HDi engines
– Before purchasing, always compare the part number on your original valve with the listed OEMs: 9665886280, 9801887680, 1618.KC
– Check compatibility by VIN if unsure

Typical symptoms of a defect (when to change the part)
– Loss of power, idle mode, turbo pressure fluctuations
– Whistling/incorrect regulation, turbo/EGR related error codes
– Damaged or leaking vacuum hoses (we recommend checking and possibly replacing at the same time)

Condition and packaging
– Used original PSA part, functionally tested
– Supplied without mounting accessories unless otherwise stated
– The condition corresponds to the product photos

Replacement/OEM numbers to search
– 9665886280
– 9801887680
– 1618.KC (1618KC)

Assembly tip
– Check the vacuum hoses and their routing (VAC/OUT/VENT), replace fragile hoses if necessary
– After assembly, clear error codes and perform a test drive, adaptation is usually not required
