Hi,
I'm asking for a friend who recently bought a 2011 sdv6.
He's having a bit of trouble with it and recently had the egr valves replaced with new genuine ones but the fault still keeps coming on.
He wants to just blank them off so no more issues but can't seem to find someone near him (st Albans) that can do the mapping part.

Is it a specific software or would most gahrahes be able to do it?

My understanding is you can't blank them on an SDV6.
Sometimes taking it to a main dealer for a full diagnostic on an LR machine is worth the time and money spent...IMHO Visitor from fullfatrr.com

Oh. He's been told by 2 garages that he can.
Best to find the exact fault then.

Tell him to call Bell Auto Services or Alive Tuning for the definite answer Visitor from fullfatrr.com
