I have just had my injectors replaced as part of a recall by Audi. They replaced the injectors but not the looms. Since getting the car back - when left overnight it is then difficult to start or starts and runs rough for 1-2 seconds. It does not appear to be related to ambient air temperature as it does it when above 12 degrees c. On odd occassions it does not do it at all ! Have you heard of an other cases and if so what the fix is ? Thank you.
