Open Circuit Faults - 1-1200km after 2.0T Coil Swap

[julex]

As far as water, I've never had an issue and I've had them in both Florida and Kentucky so not dry either place. [...] The R8 coils work just fine, and seat so tight that I have to lever them out so as long as you have the spacers you should be good.

I thought so as well and had to use pry bar to remove them every time I was going to change plugs... problem is that while the rubber wedges itself in there pretty well, the standard aluminum plates are not cut to seal right and in addition to that, water gets in between plate and head surface. I dare you to give your engine a good long wash .

While you mileage might vary on this, why not get the part that was designed for this specific type of valve cover and is of right length too. Yes, RS6 coils don't need plate, they simply bolt down just like stockers using the same gaskets and bolts (this will also ensure that coil won't pop out of the hole either which happened to me once or twice with 2.0t ones).

Agree completely with you. I was just saying that I haven't had any problems with mine, though I don't wash the engine very often. As far as the plates go, a bit of the high temp silicone, the same you use one the valve gaskets, between the plate and the cover creates a watertight seal.
If I were starting from scratch I would probably go with the RS6 coils, since they are likely better off overall. But if he already has invested in the plates and the R8 coils, a little tube of the silicone is a lot less than six new RS6 coils. jmho

Agree on use what you have although I simply sold my set and got RS6 instead, much happier here. Funny though how even 034 is backpedaling on the whole 2.0t conversion using 2.0t coils and it pushing RS6 coils instead as they simply are more bulletproof setup and don't generate issues push-ins do.

Interesting. Once the wiring has been converted can you run either FSI or RS6 coils? I'm blowing through my OE coils and it's getting old...

Yup, the coils are identical electrically with the same connectors.

Yeah, it's curious why they didn't go with the RS6 from the get go, would've saved them the money on developing the adapter plates. I guess they are a little bit more, 10-20 bucks depending on supplier, but that's offset by the plate cost.
What someone needs to go ahead and do is just start fabricating entire replacement wiring harnesses with the new plugs and icm delete already completed. Most guys are dealing with harnesses that are already on their way out anyway. Would be a much cleaner engine bay than either the solder method or the adapter method.

And don't feel bad Zba, I was blowing a coil every 2-3 months when I was just at stage 2... Can't even imagine how bad it would be now that I'm full stage 3!

[Zba]

I loaded my stage 3 tune a month ago and have blown through at least 10 coil packs. Of course these are all old ones I've had laying around but still.

Why does upping the boost blow out coils? Is there a request for a ton of spark and the old coils cant handle it?

Don't quote me on this but my theory is the added fuel requires a hotter spark in order to ignite everything in the chamber. The oe coils fail with regular injectors, bump up to the supersize ones used in stage 3 and it's gonna kill the coils quick... But like I said, that's just my theory
