About this category
This category brings together exchange-standard components for vehicles fitted with the 1.6 dCi 140 diesel engine, a unit shared across several Renault, Nissan and Dacia models over the years. It is built for anyone who needs a working replacement rather than a full repair: the independent garage juggling several jobs a day, the driver stranded with a warning light, the owner who prefers to fit the part themselves, and buyers in Germany, Austria and Switzerland searching in their own language. Every reference here is tied to this specific engine, not a generic turbo family.
The range is built the way a parts distributor thinks about stock: each reference is checked against the engine it fits before it is listed, then grouped so that a search by engine code returns exchange-standard units rather than a mix of unrelated turbos. A wholesaler's role here is to keep that mapping current as vehicles age and part numbers evolve, and to make the exchange process itself - sending back the worn core - straightforward for both a workshop and an individual buyer.
Professional uses by trade
The same 1.6 dCi 140 turbocharger reference gets searched for very different reasons depending on who is looking. A workshop, a stranded driver, a home mechanic and a German-speaking buyer each start from a different symptom or a different question, but they converge on the same engine and the same part.
- Le garagiste independant : Checks the 1.6 dCi 140 reference against a vehicle's registration document before ordering, so the exchange turbocharger fits correctly on the first attempt.
- Le garagiste independant : Orders the exchange unit ahead of a scheduled job so the worn core can be returned the same day the replacement part goes on the vehicle.
- L'automobiliste depanne : Searches for the exact 1.6 dCi 140 turbocharger reference after a warning light or a sudden loss of power, hoping to get back on the road quickly.
- L'automobiliste depanne : Reads through the compatibility details before contacting a garage, so the conversation about a replacement part starts from a confirmed reference rather than a guess.
- Le passionne qui fait lui-meme : Compares the exchange-standard turbocharger against the original part removed from the engine bay, checking the fitment points before placing an order.
- Der deutsche Kaeufer (DACH) : Looks for the 1.6 dCi 140 reference in a catalogue that lists compatibility clearly, since engine details matter more than the brand printed on the box.
Range comparison
The two references available for this engine cover the exchange-standard turbochargers most commonly requested for the 1.6 dCi 140. The table below groups them by intended use and by the wholesale format they are supplied in, for a quick side-by-side comparison.
| Range | Use | Format |
|---|---|---|
| SL Turbo 883861-5001S | replacement for 1.6 dCi 140 | |

How to choose
Choosing between references on this page comes down to a handful of practical checks rather than brand preference. The points below cover what actually changes between one exchange-standard turbocharger and another for the 1.6 dCi 140 engine.
- Confirm the exact reference against the vehicle's engine code before ordering, since two engines with a similar power rating can still take a different turbocharger.
- Check how the exchange unit is packaged for transport, since a turbocharger travelling loose in a box is more exposed to damage than one secured on a dedicated support.
- Ask how the core return process works before the order ships, since the worn unit usually needs to go back within a set window to close the exchange.
- Look for consistency between units of the same reference, since a garage ordering the same part twice expects the same fitment and the same connectors.
- Consider how quickly a reference turns over in stock, since a part that moves regularly is less likely to have sat unused for an extended period.
- Compare the wholesale terms offered to professional buyers against the retail price shown to an individual customer, since the two audiences rarely order the same way.
Storage & logistics
Storing a reconditioned turbocharger between arrival and installation is less about temperature control and more about handling: the unit should stay upright, supported at its housing rather than by its actuator or hoses, and kept away from dust before the seals are exposed. For a workshop holding several references at once, grouping stock by engine family rather than by supplier makes a busy morning faster, since the 1.6 dCi 140 references stay together instead of scattered across shelves organised by brand. Returning the worn core promptly keeps the exchange cycle moving for the next order.
We have followed the 1.6 dCi 140 engine family since 2026, and the exchange turbocharger references for it remain among the parts our team checks most carefully before every listing goes live.— autoKUR team
