Citroen C5 2.0 HDI 136 Tuning options available:

Citroen C5 HDI 110

Stage 1 Remap DPF delete (Siemens SID803) - Our Stage 1 remap gives 170BHP and a torque increase of +40Nm. We've developed these remaps not only to give optimal performance, but also to remain within the limits of the stock hardware of your vehicle so you don't need to worry about your clutch or your dual mass flywheel. Power delivery will be smooth and constant through the entire engine range and will make overtaking much easier.

The 2.0 HDI 136 comes fitted with a DPF system, you'll need to remove this for the full power stage 1 remap. Luckily HDI Tuning Ltd have a safe and reliable DPF delete solution which won't give future problems (many other companies will use software to remove the DPF which can cause turbo problems).

Take a look at a dyno print out for the 2.0 136 engine:

Mild Stage 1 Remap - If you're looking for a power increase without modifying your car, then the best option for you is our DPF friendly remap. This keeps AFR high to prevent the DPF filter from clogging. You'll still get good power gains with 160 BHP and +30 Nm of torque.

Online price: If you have a BDM100 tool and the required adaptors you can read/write the ECU yourself. Price £120. This requires you to open the ECU and solder to the BDM pads, we have a video guide available.

Postal remap service: You can post us your ECU and let us do all the hard work for you. Price £150.


EGR Delete

The EGR is tricky to get to on the 2.0 16v engine, and the plug needs to be removed from the solenoid before we can delete the EGR function. If you can fit an EGR blanking plate before your remap this will be beneficial, but it isn't 100% necessary if the EGR is not stuck open, as removing the electrical connector will prevent it from operating, associated faults will be removed from the ECU.

You can't remove the EGR without removing the DPF system as it is required during regeneration. If you're not sure if you require EGR delete, please read here.

Important: These options are only available for cars fitted with the SIemens SID803 or SID803A ECU, please double check before bringing the car in to us.
