Hi

My EE light came on this evening - car has been chugging slightly the last couple of weeks but has got worse in the last few days - I brought it to my local garage y'day and he put n new spark plugs, air filter & cleaned out the throttle hosing. The car seemed fine till I drove it 20 milestoday when the chugging started again and then the EE light came on! Any suggestions?? Should I bring it to my VW dealer?? Is it serious??

Thanks
