When undertaking a diagnostic job I always explain to the customer that the faults have to be fixed as found and that once fixed there may be other faults that become apparent (that may have been masked by first fault or not testable until the first was fixed).
I would rather decline a job at this stage(and have done)than have a unhappy customer later on.
However this vehicle is fixed and I believe the customer's confidence should be restored in the independent after-market.
I will let James post the fix and how he found it. but It did not need any major parts replacing (apart from the EGR valve) just a logical methodical approach (which we are all guilty of circumventing from time to time)
