Question 1

Which Renault models are covered in this turbocharger section?

Accepted Answer

The section covers Renault turbochargers supplied as exchange units, from the Master, Trafic and Kangoo vans to the Clio, Scenic and Megane passenger cars. Each model leads to the engines and power outputs actually listed.

Question 2

How do I know whether my Clio 3 turbocharger has failed?

Accepted Answer

The classic signals are a loss of pull between 1,800 and 2,500 rpm, a whistle rising with engine speed and blue or black smoke. A diagnosis is still needed: clogged variable geometry produces exactly the same symptoms.

Question 3

Is a Clio 2 1.5 dCi turbocharger the same as a Clio 3 one?

Accepted Answer

No. Both generations use the K9K, but the reference changes with power output and year of production. Compare the number stamped on your part with the one on the product listing.

Question 4

What is the difference between a Scenic 2 1.9 dCi and a Scenic 2 1.5 dCi?

Accepted Answer

They are two distinct engines, the F9Q and the K9K, with different turbochargers. An identical body shape says nothing about compatibility: the engine code settles it.

Question 5

Which turbocharger fits a Scenic 3 1.5 dCi 110?

Accepted Answer

The 110 hp 1.5 dCi in the Scenic 3 belongs to the K9K family. The Scenic model listing states the references covered for that exact power output, to be cross-checked with the year of production.

Question 6

And for a Scenic 3 1.6 dCi 130?

Accepted Answer

The 130 hp 1.6 dCi corresponds to the R9M, a more recent engine than the K9K and a different turbocharger reference. Check the power output on the registration document before ordering.

Question 7

Does a Megane 3 1.5 dCi 110 turbocharger fit a Megane 4?

Accepted Answer

Not automatically. The Megane 4 received engines distinct from those of the Megane 3, including at similar displacements. The model listing states what is covered per generation.

Question 8

Does the Megane 3 RS take the same turbocharger as the diesel versions?

Accepted Answer

No. The Megane 3 RS is a petrol turbo, unrelated to the dCi turbochargers of the diesel versions. It is a family of parts in its own right.

Question 9

Kangoo 1.5 dCi turbocharger: what should I check first?

Accepted Answer

The diesel Kangoo uses the K9K across several power levels and several model years. Note the exact power output and the year of production: on this model, two seemingly identical vehicles can differ.

Question 10

Master 3 turbocharger: what needs checking?

Accepted Answer

On the Master 3, the 2.3 dCi exists at several power levels depending on the model year. Note the power output and the year, and check the state of the exhaust line before blaming the turbocharger.

Question 11

Do the Trafic 2 and Trafic 3 take the same turbocharger?

Accepted Answer

No. The Trafic 2 runs 1.9 and 2.0 dCi, the Trafic 3 the 1.6 dCi of the R9M family. These are different turbocharger references.

Question 12

How does the core deposit work on an exchange turbocharger?

Accepted Answer

Your old part keeps a value: it returns into the circuit and is deducted. The core deposit section details the amount withheld and the return arrangements.

Question 13

Does clogged variable geometry always mean replacing the turbocharger?

Accepted Answer

Not always: vanes seized in carbon deposits produce the same power loss as a failed turbocharger while the part may be mechanically sound. Diagnosis must come before the order.

Question 14

Where is the reference stamped on the turbocharger?

Accepted Answer

It appears on a plate or an engraving on the housing, on the compressor side. If the engine is already open, that is the safest marker: search by reference then removes any model ambiguity.

Question 15

Do older Renault turbo models such as the R19 or R21 belong in this section?

Accepted Answer

These petrol generations follow a different logic and their availability is checked model by model in the section. On such vehicles the state of the oil lines counts as much as the part itself.
