Establish the source of the fault
Poor running or an engine warning can have several causes. Tell the workshop what has changed and provide any fault-code information you already have. This helps guide assessment of the EGR system and related components.
Match the repair to the system
The valve and related cooler arrangements vary by engine. Turner Brothers will explain which components need attention and quote for the proposed replacement work, including the associated parts needed for that vehicle.
Keep previous repairs in view
Mention recent EGR, DPF or engine work, particularly if the concern has returned. Knowing what has already been attempted helps the team plan the investigation and discuss the next repair with you.
