Pls bear with me, new here.
Done 41K in 2012 passat saloon, 2nd service 1 month ago. Last couple of days noticed that when car sits for 6hrs+ it has reduced power when started and rattles like hell - okay after 5 mins BUT fuel consumption down from 60 to 49 approx. Do 130 miles/day, problem happened on way to work and on way home from work. Any ideas?? Is it likely to be heading for a major failure?
Thanks
