I have a problem with my 130 tdci 56 plate 38 k miles.
On 2 occasions over the last 3 months the engine has lost power but continues to run very sluggishly. By shutting down and allowing 15 minutes and then restarting the problem goes ie normal performance returns.
There is no warning lights or black smoke when this happens and overall the car still runs as new.
Has anyone any ideas about a solution as my main garage require silly money to carry out a diagnosis
