EGR Delete

EGR Valve Problems on Diesel cars

As the EGR valve is constantly working with burnt exhaust gases they naturally have high soot content. This soot in the gases causes a build-up of carbon deposits around the valve operation area which in turn causes the valve to have a tendency to stick in various positions. Also the soot/gas mixture leads to deposits in the inlet manifold compromising performance and the operation of the manifold flaps.

For full engine performance the EGR valve is closed which creates a closed loop environment for the turbo system which allows it to pressurise. A problematic EGR can create an open loop environment for the turbo as it provides a feedback straight to the intake manifold and as a result can cause boost issues along with huge reductions in power and also fuel economy!

Benefits of EGR Delete

  • Restored Engine Power
  • Restored MPG
  • Cleaner emissions as faulty EGRs create much higher soot deposits
  • Can prevent DPF failure as the soot is caught in the DPF trap
  • Can prevent EGR replacement which can cost hundreds of pounds
  • Still 100% MOT compliant

Having your EGR deleted in the software can save you money in repairs and fuel costs. AHMs EGR Bypass software can correctly remove the functionality from the software of most ECU types. Some companies will simply turn off the codes associated with it being unplugged, but this is not the correct way. The EGR valve needs properly disabling to ensure it is not trying to recirculate exhaust gases whilst still physically working in the engine.
