The ECU is unlocked in the sense that the immobiliser is removed, so you can connect this ECU straight to your vehicle and the engine will start without you needing to recode the ECU.
The ECU is also remapped, this is set to 125 BHP and 270Nm, this will make a big difference to overall drive ability and you'll also get slightly better fuel consumption during normal driving.
We specialise in making high quality remaps for the HDI engines, so you can buy this ECU knowing that you'll get the best remap and it's completely safe for your engine to run.
It's important you match up the codes on the ECU which are Siemens SID801 5WS40020H-T, if this is different, get in touch and we can match one up for you.
These ECUs are a good buy if you have an immobiliser problem.
