Custom remap stage 2 on this BMW 320d Msport diesel

We recently carried out a stage 2 on this F30 320D.
DPF,EGR and swirlflap delete all done with EGR Physically blanked and a mild hardcut limiter.

The customer had on going issues with the EGR which would cause the car to sometimes cut out and run rough, so we thought the best option would be to delete the emissions system and give it more power

We custom tuned this on the road making multiple logs and revisions the car now drives nice and smooth with an amazing powerband this 320d achieved around 220bhp however we where limited by not tuning the TCU which will be done in the near future.

🚗 NEW SERVICE – PETROL INJECTOR TESTING 🚗

We now offer injector testing for petrols including GDI,PIEZO and TFI

We have the correct specialist equipment to be able to repair and refurb your injector the SAME DAY.

We stock a wide range of injector seals and baskets in stock this allows us to repair majority of GDI and top feed injectors.

All injectors servicing receive the following:

Flow testing at various speeds, pressure and pulse
Resistance test
Ultrasonic clean
Back flushing of the injectors
A PDF health report of each injector.

Replacing seals and Injector baskets are done at an extra cost.

From our experience, The main cause of why injectors fail is mainly due to the use of poor fuel quality or the use of fuel additives, this causes the mesh filter baskets to disintegrate and block the pintle from operating correctly. The second cause is carbon buildup which is commonly found on GDI and PIEZO injectors. Various injectors do have electrical issues and can short circuit internally or can simply have a weak coil however this is rarely the case

We also offer upgraded stainless steel filter baskets that don't suffer from deterioration

If your vehicle is suffering from poor fuel economy, rough idling, lack of power, hesitation when accelerating, excessive smoke or difficulty starting then you may need to service your petrol injectors

Our testing process allows us to identify:
✅ Blocked or partially blocked injectors
✅ Uneven fuel delivery
✅ Leaking injectors
✅ Poor spray patterns
✅ Fuel system performance issues
✅ Excessive smoke
✅Fuel trim issues
✅ Performance issues and misfires

Faulty injectors can affect engine performance, increase fuel consumption, and lead to costly repairs if left unchecked.

By testing your injectors, we can help restore engine efficiency, improve performance, and ensure your vehicle is running as it should.

We can also remove and test your injectors in-house.

📦 Postal service available nationwide
🚗 Drop-off and collection service available

And a video of us flow testing a BMW M6 PIEZO injectors after the owner wanted to verify correct flow in the injector before re assembling the engine

Bmw Intermittent Drive Train Fault!!

This Bmw 318d 2.0d N47 was booked in for a diag session after the customer went to multiple garages to fix a simple egr issue.

it was suffering from the very common fault on majority of n47/b47 which is egr failure which flags up the following dtcs:

• P0402 EGR Excessive flow detected
• P042F EGR Stuck closed
• P2002 DPF Efficiency low (Not related to EGR)

These are very common for EGR valve failures, carbon builds up into the EGR and doesn't allow proper movement of the EGR valve, normally when this is the case it's always best to Delete the EGR system or replace both the EGR Valve and the EGR Cooler. cleaning it may work but it's always best to replace or delete (we stock egr valves and coolers for these).

The P2002 was the main reason for the intermittent fault as the sensor was reading a minus number even with the engine switched off, new sensor and relearn and it was sorted.

We applied our EGR Delete and blanked egr off so no more future issues, sorted out the back pressure readings on the dpf by replacing the sensor.
