I was driving my colour edition yesterday and the car went all judders and tge ecp light came on. I took it to my local garage and it said cylinder 1 is misfiring. He didn't believe it was the spark plugs and replaced the coil pack, but the car is the same. 5k miles off due service. Ang ideas to fix this would be greatly appreciated.

Hi, welcome.

There are a lot of this things that can be or feel like a misfire. You really need to have a scan tool report and perhaps live data to start a diagnosis on these cars with complicated and intwined computer systems but very often the results can take you to the old basics of the ancient technology that an internal combustion engine is.

If there is a suspected misfire caused by a coil pack then to check and confirm this isn't difficult, same for spark plug. There could be a coincidence of faulty coil and/or plug and other issue(s) causing the problem but just fitting parts until you hit on the cause isn't usually the most productive way of diagnosis and generally parts and labour costs make an escalating process like this disproportionately expensive.

ECP in a 2019 might (or might not) relate to a throttle body issue, does your local garage specialise in VWs, even if not there might be trade information on this available on the databases they have available.

If the car is a three-cylinder then having one out of three spark plugs play up will be noticeable, when were they last changed?.

A service nowadays is basically just an engine oil and filter change and a look for more chargeable work which isn't even a service of the engine let alone a service for the whole car and the much more important components and systems on the car so forget how many miles or the time to the next service for this issue.

Some Briskoda members offer to use their scan tools to at least give reports that will show errors codes that exist, perhaps clear them, perhaps get live data, start of diagnosis, most for beer tokens, a few are professionals so different renumeration. Have a look at the link at bottom of this post to a post in the link for the list and map of these Briskoda members to see if there might be someone suitable able to help you.

If you want to you could add to your 'Author's stats' your car's engine and gearbox details as Colour Edition is more about trim level rather than mechanical.

HTH.

Welcome to the forum.

Were the 3 spark plugs out and inspected and the gap checked before given the OK?

How many miles has the car done and when were the spark plugs replaced?

A failing spark plug can cause the premature failure of an ignition coil.
