Question 1

How much is a high-pressure pump for a SSANGYONG Rexton?

Accepted Answer

An exchange high-pressure pump for the SSANGYONG Rexton starts at €365.00. A single reference, R9044A051A, covers this model: the price shown is that one part, with no variant to compare.

Question 2

Which high-pressure pump reference fits a SSANGYONG Rexton?

Accepted Answer

The reference is R9044A051A. It is what settles the match on a SSANGYONG Rexton — not the vehicle's trade name, nor its year.

Question 3

Why is only one pump reference offered for the Rexton?

Accepted Answer

Because the Rexton engines listed here were built with the same high-pressure pump. The choice is unique, which rules out any risk of mismatch.

Question 4

Where is the reference found on a pump removed from a SSANGYONG Rexton?

Accepted Answer

It is stamped on the nameplate. The marking stays readable even on a part coated with grime. It is the only reading that confirms the match with the reference expected on a SSANGYONG Rexton.

Question 5

How do I find out which engine my Rexton has?

Accepted Answer

The registration document states the version and the rated power of the vehicle; the engine code itself is stamped on the block. That engine-and-power pairing places the car within the Rexton range, and leads to the right pump reference.

Question 6

Is the year of my Rexton enough to choose the high-pressure pump?

Accepted Answer

No. Two Rexton of the same year can take different pumps depending on their engine. It is the engine-and-power pairing that determines the reference, and the reading on the nameplate that confirms it.

Question 7

What happens to the old pump from my SSANGYONG Rexton?

Accepted Answer

The part ordered is sold as an exchange unit: it has already been remanufactured, and the pump you remove from the Rexton goes back into the reconditioning circuit. Return terms are stated at checkout.

Question 8

How does an exchange pump differ from a new part?

Accepted Answer

An exchange high-pressure pump is an original part restored to working order: wear parts are replaced and the assembly is pressure-tested. It carries the same reference as the pump removed from the Rexton and fits in its place.

Question 9

How do I spot a worn high-pressure pump on a SSANGYONG Rexton?

Accepted Answer

On a SSANGYONG Rexton, a failing pump shows up as long cranking, hesitation under acceleration, a loss of power under load and a drop into limp mode. These signs overlap with other fuel system faults: diagnosis is a job for a qualified technician.

Question 10

Why does my Rexton go into limp mode?

Accepted Answer

The ECU of the Rexton limits the engine when rail pressure no longer reaches the value the engine expects. A high-pressure pump that no longer holds pressure is one possible cause, alongside a clogged filter or a faulty regulator.

Question 11

Does long cranking always come from the high-pressure pump?

Accepted Answer

No. Long cranking can come from the pump itself, but equally from a fault on the fuel filter, the pressure regulator or the common rail. The symptom alone is not enough to condemn the part.

Question 12

Which common rail pump range does a Rexton take?

Accepted Answer

The CP1, CP3 and CP4 pumps of the Bosch range are covered, and it is the reference that names the one fitted from the factory to the engine in the Rexton. The range alone is not enough to order: the reading on the nameplate settles it.

Question 13

How do I confirm the fault before ordering a pump for the Rexton?

Accepted Answer

By a fault code read and a rail pressure check, carried out by a qualified technician, before any order for a SSANGYONG Rexton. That check separates a failed pump from a clogged filter or a leak elsewhere on the circuit — faults with similar symptoms but different remedies.

Question 14

Can I order a pump for the Rexton without knowing the exact reference?

Accepted Answer

This page lists a single reference for the Rexton, R9044A051A: the reading on the nameplate then serves to confirm, not to choose. Where the engine is in doubt, the check belongs to a qualified technician before ordering.

Question 15

Does a pump ordered for a SSANGYONG Rexton fit straight on?

Accepted Answer

Yes, provided the reference is the original fitment for the engine in the Rexton: it keeps the drive, the mounting and the connections of the part removed. Fitting is a job for a qualified automotive technician.
