Chuggin

Hi,

Got an 07 Superb Classic 1.9tdi , its been mapped for consumpton has run like clockwork last eight months with regular servicing ...timing belt replaced at 60thou now at 73K miles. Just serviced . Even before this latest service I noticed when in gear around 30mph .... with foot off the accelerator the car does drop rpm but very slowly and chugging is quite evident but seems to hold rpm and roll on without any footpower???....only when in gear and rpm on the drop ( the car seems to be getting juice when it should not ie foot off power).

Any ideas .... what it could be and how much to repair ,.....give all possilbles please when time permits.

Regards,
