I recently got a 2012 Golf 1.4 TSI. Noticed that the spark plugs have never been changed so thought I'd do it in the hope of improving fuel economy. However I'm struggling to remove the ignition coils. I bought the Draper tool which gives a good grip on the coils but no amount of pulling will get them to budge. I've never had this much trouble with other cars. Am I missing something? Would it be easier with a warm engine? Any advice would be appreciated!
