Continental SIM2K-510 on Hyundai & Kia 1.6 CRDi: DPF, EGR, AdBlue OFF, Stage 1, DTC OFF, Map Packs and DAMOS

Language: English · Русский · Español · Türkçe · Polski

The Continental SIM2K-510 is the engine ECU of the newest Hyundai and Kia small diesels — the 1.6 CRDi in the Kona, Tucson, i30, Ceed, XCeed, Sportage and Stonic, including the 136 hp 48V mild-hybrid versions. For years it was one of the hardest units to work with: no tool could read it over OBD, and workshops were left with emulators for AdBlue and DPF problems.

That has just changed. Reading by OBD has arrived in the professional tools, and we have finished our own software solutions for this ECU — DPF, EGR and AdBlue/SCR OFF, Stage 1, Start/Stop OFF and selective DTC OFF, plus WinOLS map packs and DAMOS for almost any software version on request. This guide shows which cars carry the SIM2K-510, how to read it, what we do in the file and how to order.

What the SIM2K-510 is

SIM2K is the family of engine control units that Continental (formerly Siemens VDO) develops for Hyundai Motor Group. Most SIM2K versions run petrol engines — the SIM2K-24x units in the 1.6 T-GDI and 2.0 T-GDI, for example. The SIM2K-510 is the diesel member of the family: it controls the 1.6 CRDi U-series engine (marketed on newer models as Smartstream D1.6) in its 115 hp and 136 hp versions.

Inside is a 32-bit Infineon AURIX controller with several megabytes of flash. The software is split into a bootloader, the program and the calibration. On the newest cars the ECU talks to the diagnostic port over CAN-FD, the faster CAN standard Hyundai and Kia introduced on their recent platforms.

The emission hardware around it is complete: diesel particulate filter, high- and low-pressure EGR, NOx sensors and, on Euro 6d versions, SCR with AdBlue — the AdBlue dosing has its own control module (DCU, often called ACM in workshops), but the engine ECU decides whether the SCR system is active.

Which Hyundai and Kia models use it

The list follows our file-service vehicle database and the vehicle lists published by the tool makers. Torque goes from 260 to about 320 Nm on the 115 hp version and from 280 to about 330 Nm on the 136 hp version; exact figures per car are on the linked catalog pages. Other Hyundai and Kia diesels — the older 1.7 CRDi and the 2.0 / 2.2 CRDi — use Bosch EDC17 or Delphi ECUs instead, and the petrol 1.6 T-GDI uses other SIM2K versions.

Check the ECU, not only the model. Engine and ECU changed during production of several of these cars. If the car is from 2018 or later and has the 1.6 CRDi, it is almost certainly a SIM2K-510 — your tool will confirm it in seconds.

How to recognise the ECU

• The label carries a Hyundai part number (for example 39100-2U720), a Continental serial number and the text SIM2K-510.
• Your tool identifies it as Continental, Kefico or Siemens SIM2K-510 — the name depends on the tool, the unit is the same.
• The software ID in the file starts with the calibration name of the vehicle line. Send us the read and we will tell you which version you have and which options are available for it.

Reading: OBD, CAN-FD and bench

Until recently the SIM2K-510 could not be read by OBD at all. In 2026 professional tools added support: Magic Motorsport, for example, announced OBD reading and writing for the SIM2K-510 on Hyundai and Kia with automatic unlock, including the CAN-FD versions (writing on CAN-FD needs their newer adapter). Bench and boot reading of the unit is also possible.

Always keep the original read. If you do not have one, look in our original files database for SIM2K-510.

What we change in the file

DPF OFF

The regeneration strategy and the soot model are switched off, so the ECU no longer requests regenerations or post-injection. Monitoring of the differential-pressure sensor and the particulate filter efficiency is disabled, and the related fault codes and warning lights are removed. Combined with EGR OFF it gives a clean, stable engine without the classic short-trip problems.

EGR OFF

The 1.6 CRDi uses both a high-pressure EGR valve and a low-pressure EGR loop with an exhaust back-pressure flap. We close the EGR in every operating mode, take the flap out of the control loop and remove the related codes (EGR flow, position, cooler and flap circuits such as P0475–P0478). The air path is recalibrated so the engine runs as if the system were healthy.

SCR / AdBlue OFF

On Euro 6d versions the AdBlue dosing has its own control module (DCU / ACM), but the engine ECU decides whether the SCR system exists. We configure the SCR system off in the engine ECU, neutralise the inducement logic (the distance countdown to a start inhibit) and remove the AdBlue, NOx-efficiency and communication codes — including the codes for the missing module.

A complete solution — the AdBlue module can be removed. The modified file works with the DCU / ACM disconnected or taken out of the car: no communication errors, no AdBlue warnings, no countdown. No emulator and no extra wiring are needed. You can also leave the module in place — the file works either way.

Start/Stop OFF

The automatic stop is disabled in the engine ECU itself, including the temperature conditions it uses, so the system stays off after every start — no button press, no warning on the dashboard.

DTC OFF

The SIM2K-510 keeps about a thousand diagnostic events in its own tables. We disable exactly the codes you name — for a removed sensor, a known false alarm or a component that is no longer fitted — and leave all other diagnostics as from the factory.

Stage 1: power and torque

Stage 1 is calibrated on the real limiters of this ECU: the torque limitation, the smoke limiter by air mass, injection quantity and timing per combustion mode, rail pressure and boost. Rail pressure and boost stay within the limits of the stock hardware, and the gearbox torque limits are respected — on manual and DCT versions alike. The mild-hybrid 48V system keeps working as before.

WinOLS map packs and DAMOS

Tuners who prefer to write the file themselves can order a WinOLS map pack for the SIM2K-510. For the reference 1.6 CRDi calibrations it contains more than 1,300 named maps — torque and smoke limiters, injection and rail-pressure maps per combustion mode, boost, EGR, DPF, SCR, Start/Stop and the diagnostic tables — with correct axes, factors and units. For other software versions the maps are transferred and checked against the program code before delivery.

We also create DAMOS files for almost any SIM2K-510 software version on request. Send the read, we check the version and quote the price and delivery time. Read more about custom DAMOS creation or browse the map pack database.
