Summary We rebuild Hella electronic turbo actuators, the motorised units bolted to most Garrett variable-geometry diesel turbochargers and to a few others, from £100 + VAT. Your own unit is rebuilt at component level, bench-tested and returned ready to refit without coding, typically after one to two working days on the bench, with a lifetime, unlimited-mileage warranty.
This page works from the part rather than the car. Find the Hella 6NW number on your actuator, see every vehicle our model pages record it against, and follow the link to the page that holds the detail for that vehicle.
Hella 6NW009420 is recorded against a BMW 530d, a Mercedes E280 CDI, a Jeep Grand Cherokee 3.0 CRD and the Vito: three manufacturers, one Hella number.
Most people searching for a Hella turbo actuator already have one in their hand, or a photograph of one, and want two answers: what it fits, and whether it can be saved. The lookup table answers the first from the references our vehicle pages already document. The rest of the page answers the second.
- The maker: Hella, the German component maker, supplies the electronic actuator fitted to many Garrett variable-geometry turbochargers
- Not only Garrett: our pages also record Hella numbers on a Mitsubishi-family turbocharger (BMW 520d F10) and on a BV45 (Nissan Navara D40)
- What is on the casing: a Hella number in the 6NW form, often a base number such as 712120 or 781751, and a G-code
- Numbers indexed here: 6NW008412, 6NW009206, 6NW009228, 6NW009412, 6NW009420, 6NW009483, 6NW009543, 6NW009550, 6NW009660, 6NW010099 and 6NW010430
- Typical faults: a broken worm gear or burnt-out motor behind a carbon-stiff vane ring, loosened board connections, oil or fuel contamination
- Our service: your own unit rebuilt from £100 + VAT, typically 1–2 working days, no coding on refit, lifetime unlimited-mileage warranty
Hella Actuator Reference Lookup
Each row starts from a Hella number and lists the G-codes and vehicles our model pages record against it. If only the G-code is legible, search this page for it: every code sits in the row of the Hella number it was listed with. For where each marking sits on the unit, see how to read the reference on your casing.

Read the table as a record of what catalogues and listings say, not as a fitment promise. A row tells you which pages to read. The full set of references on your own casing, the Hella number, base number and G-code together, decides which unit you have.
Where the Same Hella Unit Turns Up Across Makes
Hella does not design an actuator for a car. It supplies the unit to the turbocharger maker, and the turbocharger is then fitted to whatever engine it was specified for. That is why the table crosses manufacturer lines so often, and the crossings follow three patterns.
One engine, several badges
The Mercedes-built 3.0 V6 diesel went into the C-Class, E-Class, CLS, CLK, Vito and Sprinter, and the same engine family powers the Chrysler 300C, Jeep Grand Cherokee and Jeep Commander 3.0 CRD. Their actuators follow the engine, so 6NW009420, 6NW009660 and 6NW008412 appear across all of those pages under G-219, G-277 and G-001. Our Mercedes CLS page sets out the reference combinations for that family most fully.
The 2.2 diesel catalogued as DW12B does the same thing across two brands. The early Freelander 2 2.2 TD4 and the S-Max, Galaxy and Mondeo 2.2 TDCi share Hella 6NW009483, but the Land Rover listing carries G-62 and the Ford listing G-50.
Different engines, one Hella number
The less obvious crossings join vehicles with no engine in common. 6NW009550 is recorded as G-013 on the BMW 525d, 530d and 730d, against a 758351 turbocharger, and as G-59 on the Ford Transit 2.2 TDCi built from 2011 to 2016, against a Garrett GTB1749VK. The detail sits on our BMW 5 Series and Ford Transit pages, and the G-code is what keeps the saloon’s unit and the van’s unit apart.
6NW008412 travels further than any other number here. BMW four- and six-cylinder diesels, the Ford Mondeo and Jaguar X-Type four-cylinders, and the Mercedes-built V6 all carry it, so matching it proves very little on its own.
Hella is not a synonym for Garrett
Most Hella actuators on UK diesels sit on Garrett turbochargers, and many listings use the two names interchangeably. Our pages record exceptions. The BMW 520d F10 and F11 carry 6NW010430-04 on a Mitsubishi-family turbocharger, and the 140 kW Navara D40 carries 6NW010099-01 on a BV45.
The naming also runs the other way. Some Transit 2.2 TDCi vans carry a Garrett-coded variant, numbered 6NW010430-22, where others carry the Hella-branded 6NW009206 or 6NW009550. A brand name on a listing tells you less than the numbers on the part.

When Two Units With One 6NW Number Are Not the Same Part
The table already shows the pattern: 6NW009660 under three G-codes, 6NW009228 under five, 6NW009483 under two. Our BMW 5 Series page explains why the G-code rather than the Hella number identifies the unit, so that argument is not repeated here. Two further points apply to every number on this page.
The suffix is part of the number
Some Hella numbers carry a dash suffix, and the suffix changes the part. 6NW010430-04 is the BMW 520d F10 and N47 3 Series unit, while 6NW010430-22 is the Garrett-coded Transit variant. 6NW010099-01 is catalogued for the Navara and 6NW010099-02 for the BMW N47. Record the number with its suffix, exactly as printed, and treat a number without one as incomplete.
Some differences are inside the casing
Repair-kit listings show how far the variation goes. One UK supplier’s kit for Hella-style actuators on Garrett turbochargers, a replacement worm gear and drive motor, tells buyers to match from the part number and not the turbocharger frame size. It then asks them to unclip the six retainers holding the cover, count the teeth on the worm gear and check the motor’s own part number before ordering, warning that the many variants look very similar and carry similar numbers.
That is a hurdle for a kit buyer rather than for a rebuild. The unit we rebuild is the one already set up for your turbocharger, and what is inside it is examined on the bench instead of inferred from a listing.
What Fails Inside a Hella Actuator
A Hella unit packs a small DC motor, a plastic gear train, a position sensor and a circuit board into a sealed housing on the hot side of the turbocharger. The failures follow from that layout, and the one repair-part suppliers describe first starts outside the actuator.
- A jammed vane ring breaks the gear. When carbon stiffens the variable-nozzle mechanism, the motor keeps driving against it. Suppliers of Hella-style repair parts describe the plastic worm gear breaking under that load, and the motor burning out as it strains.
- Gear and rack wear. Short of breaking, stuck vanes wear the gears and rack in the mechanical section, and the unit loses the precision the engine control unit expects.
- Loosened board connections. Vibration can work connections on the circuit board loose.
- Oil or diesel contamination. A unit flooded with engine oil or fuel can suffer damaged board tracks and false position-sensor signals, and in the worst cases stops communicating with the engine control unit at all.
The first of those decides whether any repair lasts. An actuator that failed fighting a seized vane ring will fail again on the same turbocharger, so move the vane linkage by hand through its full travel before a rebuilt unit goes back on. Our Jeep Grand Cherokee page describes that check, and if the vanes are the problem our turbocharger rebuild service is the place to start.
For how these faults show up from the driver’s seat, see our guide to turbo actuator symptoms.
Our Hella Actuator Rebuild
You or your garage remove the actuator and post it to our workshop at Unit 102 Reaver House, 12 East Street, Epsom, Surrey, KT17 1HX, United Kingdom. Independent garages and main dealers send units in for their customers’ vehicles the same way.
- Complete the repair form. Give us the registration, the Hella number with any suffix, the G-code, a photograph of the label, the stored codes, and whether the vane linkage moved freely.
- Pack it carefully. Leave the connector intact and the housing unopened, and pad around the connector and output arm inside a rigid box. Our FAQs page covers packing and postage.
- We match it to your vehicle. The references are checked against your registration. If the unit is not one we can rebuild, we tell you before any work is done.
- We test it as received. The unit is run before it is opened, so the fault we report is the one we measured.
- We rebuild it at component level. The motor, gear train, position sensor and seals are renewed as needed and the circuit board is reworked. Where the original design has a known weakness, an uprated part goes in, so the unit meets or exceeds original specification.
- We calibrate it and send it back. Travel and feedback are set to the range the unit’s own reference demands and checked across the full sweep on dealer-level diagnostic and calibration tooling. It comes back ready to refit with no coding; clear the stored codes once it is on.
Repairs start from £100 + VAT, with the exact price confirmed once the unit has been identified and tested. Turnaround is typically one to two working days from arrival, plus postage each way. Every rebuild carries a lifetime, unlimited-mileage warranty, and we accept units posted from anywhere in the UK and from overseas.
Hella Turbo Actuator Repair FAQ
Is a Hella turbo actuator the same as a Garrett actuator?
Often it is one part under two names. Hella supplies the electronic actuator for many Garrett variable-geometry turbochargers, so listings sell it under either brand. It is not a rule, though: our pages also record Hella numbers on a Mitsubishi-family turbocharger and on a BV45, so go by the numbers on the casing.
Is the Transit’s 6NW009550 the same actuator as the BMW’s?
Not as a set-up. The Transit unit is listed as G-59 on a Garrett GTB1749VK, and the BMW six-cylinder unit as G-013 on a 758351 turbocharger. They share a Hella number, not a G-code, so neither should be fitted in place of the other.
My 6NW number is not in your table. Can you still rebuild it?
Very likely. The table lists only the references our model pages already document, not the limit of what we rebuild. Send a photograph of every marking with your registration through the repair form, and we confirm the unit before any work is done.
Can I buy a Hella turbo actuator on its own?
Rarely as a new part. Suppliers note that it usually cannot be bought separately from the turbocharger, which is why dealer quotes tend to be for a complete turbo. Repair kits for parts such as the worm gear, motor or gearbox are sold, but each has to match your unit’s internals. A rebuild renews the whole unit and calibrates it to the turbocharger it came off.
Does a rebuilt Hella actuator need coding?
Not one of ours. Your own unit is calibrated on the bench to the range its reference demands and refits without coding. Clear the stored fault codes with a diagnostic tool once it is back on.
How much does a Hella actuator repair cost, and how long does it take?
Repairs start from £100 + VAT, with the exact price confirmed once the unit has been identified and tested. Turnaround is typically one to two working days from arrival, plus postage each way, and every rebuild carries a lifetime, unlimited-mileage warranty.
Final Thoughts
A Hella number is the most useful marking on the casing for finding your way around and the least useful for settling a fitment. It tells you which vehicles, and which of our pages, to look at. The G-code and the suffix tell you which unit you actually have.
That difference only matters when you are buying a part to match. When the unit you post in is the one that comes back, rebuilt and calibrated for the turbocharger it came off, the numbers become a check we make on the bench rather than a bet you place on a listing. Make sure the vanes move freely, photograph every marking, and send the actuator.
