1.8T Coilpack installation

[Jon441cc]

Hi dave, yes i did use 14 gauge wire it was the only stuff i had at the time as i needed to get the coilpacks changed asap. The coilpack connectors were salvaged at a local scrapyard which was handy as all i needed to do was solder onto the existing wires, plus they were free (in the tool box)
I am a little concerned about the heat build up under the coilpack cover though so i may remove it.
I could not have even attempted to do this without your very detailed write up, this is what being a forum member is all about, Sharing ideas.

I'm biting the bullet and doing the conversion! Does Beru make these coilpacks?? Euro car parts are over £2 a coil cheaper than GSF but under manufacturer it says Beru. I know Beru made the original S2/S4 coilpacks so would this be an OEM part? Cheers!!

As far as I know, the problem coil packs were made by Bremi not Beru. The ones you want end in 115 L. Check out the URL for the Bremi story.

BERU are OEM - but I have bought these coilpacks from GSF and ECP and got duff ones...maybe I have been unlucky but I will stick with OEM. The potting compound on top in the GSF and ECP was a different colour to OEM - maybe they are the rejects from Audi!!

I'm a bit worried now! I bought one coilpack from my local GSF so that I could find the correct plugs from the breakers. This one came in a genuine Audi box! I found the connectors in the week and ordered the other four coilpacks from the GSF mailorder line. They arrived yesterday but were just wrapped in bubble wrap and weren't in the original boxes. They also look different to the other one, they have a slightly different sparkplug connector and are silver all the way up where as the one in the box has a gold coloured piece!!

My 115L coilpacks are sort of silver on the top , all of mine where in boxes
You got any pics merlin?

Here are some pics that clearly show the subtle differences with the coilpacks! Both are from GSF. Should I be worried or shall I just go for it tomorrow?

[merlin's S4]

And one more. This pic shows the difference at the bottom where they attach to the sparkplugs. I forgot to mention that the one with some gold on it is the one from the genuine Audi box! The other came from GSF mailorder and was just wrapped up!!

The coilpacks i got from GSF were all in seperate audi boxes and look to be the same as the ones you have shown above with the brass tubes, been in over two weeks now and not one problem

Hi!
Whats the info on the top part of the connector?
The part numbers are usually on there together with the manufacturer.
I have a couple and they resemble the one on the right. They came in an Audi box too with the corect p/n.

[merlin's S4]

I can't see any info on them at all!! The GSF part numbers are the same on the packaging. I may have to get in touch with them on Monday and look into it!

Just make sure that the coil packs snap hard on to the sparkplugs (over the hex part) regardless of the "gold" (cadmium) plating or not. Remember that you have to trim the silicon rubber "seal" (as per the directions) so that the coil pack can sit down and snap onto the sparkplug hex.

None of the 10 (5 in use and 5 spare) 115 L coil packs I have, have anything on the top. Just smooth grey plastic (no numbers or symbols). They all came new in a box from Audi.

Hi!
No, not the top of the coil.. the top part of the connector block! The part that houses the pins! The part the wiring block fits over. Its pretty faint.
On mine there is VW AG and the part number 06B 905 115L and the manufacturer - Bremi!

These GSF Coilpacks are absolutely Cr@p!!! As Doug pointed out, they must be rejects or something!! I finally completed my coilpack conversion today and I just went out for a spin. All was working perfectly and I was chuffed to bits. I got home and popped the bonnet to check that everything was ok, only to find that four of the coilpacks were attempting to escape from the top of the engine! I removed these coilpacks and upon further inspection it seems that these coils don't clip on to the sparkplugs properly. This is because inside the rubber tube the metal sparkplug connector should have a little ballbearing style clip (like on your socket sets) which clips over the top of the sparkplug to hold it in place. On four of these coils (the four that were different to the Audi coil and that came unboxed) this clip doesn't work!! I had a look down the tubes with a torch and the balls don't stick out far enough if they stick out at all! Neadless to say, I'm very unimpressed. Looks like I'll have to try and send them back and find a decent set.

Let this be a warning to any of you that are thinking about this conversion!!

I presume that you did trim enough of the rubber "sealing" ring away (as per the instructions). If you don't do this, you can not push the coil pack down far enough to get it to "snap" onto the hex part of the sparkplug. However, if you did trim the sealing ring and the "snap" doesn't happen, then I guess it is the off-spec or aftermarket coil pack 'redesign', i.e. leaving that "feature" out. IF you had to keep the non-snapping coils, there may be a way to rig a way to hold them down. (But you shouldn't have to do that if you have the proper coilpacks).

The fact that the coils may say "Bremi" should not be a worry as long as they are also the 115 L coilpacks. I am sure Bremi was forced to manufacture enough new and improved coilpacks to clear up the problem that the failures created. I am also quite sure that the level of quality control on the 115 L coilpacks would be very high, i.e. VAG would want another round of problems on the same issue.
