Audi A5 EGR Cooler Bypass

[Jason234]

Hi everyone, my Audi a5 B9 has recently been throwing these two faults. A local running centre has said they can bypass the egr cooler and delete the adblue system. I am not sure if this would make the problem worse or cause issues longer. Has anyone else experienced this?

 

thanks

You can get the adblue system and egr mapped out with a remap I believe. 

Just bare in mind any not tester that believes you've tampered with the emissions system of the vehicle can report you. But if done by a remap and the hardware still in place like the egr then they'd have no reason to believe it's been deactivated if you see what I mean

Hi Steve,

 

thank you very much for your response. The remap is what the tuning person is offering but they are asking for £500 for the remap alone and I was wondering if this is reasonable. I do understand replacing the cooler is a lot more expensive and given the fault code I am almost certain it is the EGR cooler. 
 

many thanks

I'd recommend you speak to other remappers such as revo, darkside developments, Celtic tuning as example.

Was there any updates on this I’m thinking about the EGR cooler bypass myself just curious about the engine temps going crazy after

Basically the car just gets a remap to map out the egr and adblue. I'd recommend speaking to specific tuners about this. But use a mapped who has a rolling road so that the map is tailored to the car. 

Be warned though, there's rumours DVLA are looking into ways of testing cars at MOT for emissions cheat devices. Even though knowing DVLA this could be some years off it's worth thinking about.
