I somehow doubt that they will go beyond reading the fault codes initially. O2 sensor and EGR flap has already been replaced so I shall see what transpires. The pertinent facts are that the car is only 18 months old, 12k miles and shows no other symptoms of the fault other than the "orange turtle ". I tend to agree that the cause is a build up of deposits in the exhaust system but as to why this is occurring I really haven't any idea.
I shall see what happens this time, but if (and when) it occurs again; probably October; I shall take it up with Volvo.
