Got an 06 Mk5 1.6 Club. Today doing about 50-60mph down a straight long road with the A/C on the car started intermittentely stuttering - like a slight power loss kicking in then carried on. it happened numerous times over 3-4 miles. worried it was going to end up like my Mk4 did when the EGR valve went and kept stalling all the time. No warning lights on the dashboard lit up and it did seem to regain power for a few hundred metres.
Switched the A/C off and it didnt happen (although was on different road by then so didnt get over 40). Before I book a day off to take it to the dealers anyone had anything similar? first time its happened today - the cars done 28k. cheers!
