1.6fsi coil pack removal

As the Mrs ford Mondeo is now off the road with pothole damage it looks like we will be doing a trip down to Newquay from north Wales tomorrow in the A2 (much to her annoyance lol) so I decided to do the service on it before we set off, unfortunately while removing one of the coil packs it snapped the top clean off and left the bottom part in the hole, ive managed to get it out and a friend is dropping a replacement off for me, the one that snapped off is the only original Audi one out of the four so its well overdue replacement, has anyone got any tips for safely removing them? as they seem very difficult to remove without twisting them, if there isn't a specialist tool available I might have to look at 3D printing something to pull them squarely with.

Thanks very much guys, will get one ordered now.
Just fitted the new coilpack and it's all good.
I also replaced the spark plugs with denso single electrode plugs instead of the Bosch super 4's that were in it and it seems to have improved the idle and torque, the old plugs didn't look badly worn but it's hard to tell with the super 4's as the gap isn't adjustable.

Autophilia , Would you consider selling those , looks like a glove box sized tool , my fsi was always eating coil packs ; it got the the stage where I had 2 spares in the car ...

Hi i really don't recommend those plugs the idea with the multi prong plugs is it gives a nice clean burn especially on the stratified charge -remember the injector aims the fuel at the plug so if the single prong is in the way it can affect combustion.
cheers mike
 
As the 1.6fsi isn't a direct injection engine the air fuel mix including the variable stratification process is pre inlet valve so the mixture will not be directed straight at the sparkplug tip, as it's a 16v engine with two inlet valves per cylinder there is not a direct line of flow from the injector to the plug, the air fuel mixture is swirled around the cylinder during the intake and compression stroke, I have also been told by a few guys in the Motorsport industry that multi tip plugs are not always a good idea as you can end up with a couple of weak sparks rather that one fat healthy spark.
Either way my previous two cars have run smoother on single tip plugs than multi tip plugs and the same seems true for the Audi so far.

To be honest I would rather print a few off and give them out for free, I'm waiting for a couple of new rolls of filament for the printer at the moment so will print some more off later this week if anyone wants them, they are very light weight as they are honeycomb structure inside and strong enough that you would probably break the top of the coil off before the tool gave way.

think you need to read up on the fsi and then come back. cheers mike
 
I think you need to understand the fact that I have rebuilt many engines and understand exactly how the FSI engine works before being so dismissive.

Then that will serve you very well when working on the fsi--just hope it goes better than your attempt to remove a coil pack. When your next under the bonnet take a look at the injectors and where they are located - you will be amazed to find they are in the head and spray direct into the cylinder the fuel doesn't touch the back side of the valves hence the carbon build up that fsi engines can suffer with. I think in the a2 the engine gets far more of a work out and suffers way less than the higher output bigger fsi engines that suffer with the valves gumming up completely.

This all started by me trying to help you out on your plug selection. All the best mike
 
Ok I apologise and yes you are correct about the injector location, I was mistaken as the previous FSI I worked on was a 4.2 from the a8 that had the injectors in a different location however from what I understand the injector fires and then allows the air fuel mixture to circulate during the remainder of the intake and compression stroke so it shouldn't matter what shape the tip of the plug is as it's igniting the compressed air fuel mixture not just the fuel.
 
The fuel enters at the last millisecond before the spark --hence the pocket in the piston to contain the stratified cycle. Clever stuff

Hello Autophilia
Please may I claim a printed coil extractor? I'll pay postage or whatever. Also, what printer do you have? What material do you print in? I'm in the process of buying a printer for work.

would it be possible to do me a coil puller, more than willing to pay any expenses.
