We are currently seeing alot of companies offering EGR deletes on vehicles equipped with LIVE DPF systems. We DO NOT offer this service for a number reasons. First of all, as part of the integral emissions system that was embedded into the software, the EGR and DPF systems work together in the regeneration process.

If the EGR system is deleted by means of duty cycle and airflow modification, this will have a negative impact on the DPF regeneration cycle. The DPF system was designed to work along side the EGR using different strategies in the passive and active regeneration process.

Once the EGR is modified, by default, this will upset the regeneration strategies and more often than not, result in an early DPF filter failure due to incorrect regeneration strategies.

If you require EGR Removal we would only offer this service as a complete DPF/EGR Removal. This does not affect vehicles without a DPF Filter.Prices Start From as little as £200 for EGR Removal including a Remap/Tune.

To help you understand a little bit more about EGR systems and why they ‘fail’ we have included a brief guide below if you require more info why not visit our 'EGR Explained' page :http://www.nottinghamremapping.com/egr-explained.

EGR VALVE FAILURE

Here are some of the common faults/reasons as to why an EGR Valve could fail -

Faults in the crankcase breather/oil separator/engine vent valve Increased blow by a result of wear on the piston and cylinders Turbocharger faults ie: worn bearings or blocked oil return pipe Not changing oil - oil filters or Oil level to high.

If the EGR valve is failing to open then you could be experiencing symptoms like - Nitrogen oxides increase considerably, incorrect engine performance characteristics, possibly Limp Mode, poor/no idle and increased fuel consumption.

Possible causes for the EGR Valve not be open - EGR valve stuck in position because it is gummed up Leakage/Secondary air on the vacuum side Vacuum connections disconnected or incorrectly fitted Faulty electric pressure switch converter valve.

Problems you could be experiencing when the egr valve will not close - Black/Blue smoke, Poor acceleration, Top speed is not reached, EGR valve damaged through over heating - due to incorrect control - due to high exhaust back pressure - due to non-opening blow-off valve (for turbocharger) Air flow meter or other sensor signal faulty Intake pipe in the area of the exhaust gas recirculation system partly constricted by deposits/Turbocharger could have an oil leak.
