My Audi A3 has had to have an EGR fitted twice in the last 14 months, costing some £834 each time. Apparently the warranty only lasts 12 months, yet they go soon after. This seems to be a software fault to do with remapping for emissions but effects the EGR and another part. I refuse to pay for another one if it goes again. Audi should admit this is a software fault and not expect their customers to be paying for this fault.
