EGR delete in Rochdale
Software-based ECU remap. EGR disabled permanently. We come to you in Rochdale. £220.
For off-road and track use only.
What the EGR system does, and why it fails
The EGR (exhaust gas recirculation) valve takes a controlled portion of exhaust gas and routes it back into the intake manifold. The engineering intent is to reduce peak combustion temperature and cut NOx emissions. In theory, a functioning EGR system manages this cleanly. In practice, on a diesel engine doing urban routes, stop-start work, and short runs, which describes the majority of commercial vehicles operating around Rochdale, Heywood, Middleton, and the wider motorway network, the recirculated exhaust gas carries a heavy carbon load. The engine does not reach the sustained temperatures needed to burn those deposits off. The valve passages accumulate soot. The valve itself fouls, sticks, or fails to reach the ECU's target position.
When the ECU detects the EGR circuit is not performing within its mapped parameters, it logs a fault code and triggers a reduction in engine output, limp mode, to protect the drivetrain from running in an uncontrolled state.
A software EGR delete removes the EGR system from the ECU's operating map entirely. The ECU stops commanding the valve. The fault code stops returning. The engine runs without the EGR cycle. The valve remains physically in place, nothing is unbolted, no blanking plate is fitted, no surrounding components are disturbed. The modification is carried out through the OBD diagnostic port.
Vehicle coverage
We carry out software EGR deletes on a wide range of diesel vans and cars. Commonly covered vehicles include:
Ford Transit (TDCi and EcoBlue), Mercedes Sprinter (CDI), Vauxhall Movano and Vivaro, Volkswagen Transporter T5 and T6 (TDI), Volkswagen Crafter, Renault Trafic and Master, Fiat Ducato, and diesel passenger cars across most manufacturers.
Coverage is subject to tuning file availability for your specific make, model, engine variant, and year. Not every build is covered, if you have an unusual spec or a less common engine code, call us on 0161 694 7331 with the details before booking. We will check availability and give you a straight answer.
What happens on the day, step by step
We arrive at your location in Rochdale, home address, yard, industrial unit, or car park.
Pre-remap diagnostic
we connect to the OBD port and read all current fault codes, logging everything present.
ECU remap
the modified map is written via the OBD port with the EGR system disabled in software. The engine bay is not opened.
Verification
we confirm the map has been correctly written, restart the engine, and check all systems are reading as expected.
Fault codes cleared
stored EGR codes are removed. Any non-EGR faults present will be reported to you but require separate attention.
Done, typically 60 to 90 minutes from arrival to completion.
No recovery, no overnight, no garage slot.
Cost and comparison
The EGR delete is £220. That covers the visit, the remap, the verification, and fault code clearance. There is no diagnostic charge on top, no call-out fee, and no per-hour rate. If the DPF also needs to be addressed, both can be done in the same visit for £445.
For context: a physical EGR valve replacement typically costs £300 to £700 fitted, depending on the vehicle and whether corroded components complicate the job. For a diesel doing the short-run, stop-start work that causes EGR fouling in the first place, a replacement valve will accumulate the same deposits under the same conditions. The software delete removes the system from the equation permanently. One visit. No repeat work.
Legal notice
EGR delete is for off-road and track use only. A vehicle with an EGR delete does not comply with current UK road emissions standards and must not be driven on public roads. This is the legal position and it is stated plainly. The vehicle owner is responsible for how a modified vehicle is used. We carry out this modification for motorsport, off-road, and agricultural applications only.
