Are all 2.0t coil packs created the same? Accidentally bought AWM coil packs.

[maxiz1]

Hi all,
I'm planning to delete the ICM and upgrade the coil packs. I was tempted by an online offer and bought a set of 06A905115D (it looks like all other 2.0t coilpacks). To my surprise, these coil are the OEM sets for 1.8t AWM engine. I start doubting it when the key on the coil is a bit thicker and does not fit the keyway on the tuoareg adapter plates.

So my question is? Can this be used effectively used for my 2.0t project? I'm not just talking about fitment, but also ability to delete the ICM as well as running larger gaps on the spark plugs. Thanks.

[Davdraco1]

I know the AWM and 2.0T could packs have the same connector. The 2.0t are just longer.

[tar]

Not the same. I have 2.0 on my awm for better spark, awm are just awms run lower gap vs the higher 2.0t.

It will work from what I know for icm del, just not the gapping.

[GOODBYNAAIR]

I don't remember why but for us the fsi coils run better than the tfsi . And like he said u will get better spark and more reliable. I run oem mkv gti FIS coils from amazon best price at the time. 2 years now with no problems.

I believe I have the fsi too. I'll get part number tomorrow and take a side by side pic if you need

2.0 ignition coils are longer than 1 8t, and have a higher voltage spark. They won't fit using the adapter plates. The coil end won't seat properly onto the spark plug and will basically arc vs transferring the voltage to the spark plug.

[maxiz1]

Tar - please do. Appreciate your help. Else i have to post them onto ebay.

Serlah - can you clarify about the fitment issue for the 2.0t coils? I always thought it is not a problem since from what i read the coils fit snugly over the plugs without the need of any adapter plates. Is it the red coils you're talking about?

[maxiz1]

I forgot to mention that my engine is 1.8t APU or ATW equivalent for US but the coils has the 3 pins like the AEB. Kinda weird setup.

VwVortex Coil Pack tests

Check out post #34, a guy ran some tests and found that the output is the same between the 2.0t coilpacks and the 1.8t coil packs.

Read that closely. The only thing he tested for was spark duration, not strength of spark.

[Seerlah]

2.0 coils fit right over them. But you have awm coils, which are shorter than the tsi/tsfi coils. If you use the adapter plate, that plate creates a gap/spacing that won't allow the awm to seat on the plug.

And 2.0 coils def have a greater spark. You don't even have to really test it. Gap a plug the same on a 1.8t coil as you do on a 2.0 coil and it will blow out...due to not as strong of a voltage.

[DoesntCare]

If anyone can provide some actual output tests of the two I'd love to see them.

If you read the other posts in the thread people have tested 1.8t coils vs 2.0t coils and found they were identical in spark blow out as well.

There is also a vendor listing the advantages of the 2.0t coils as being cheaper, and the added height improving the longevity of the wiring harness to the coils, but nothing about performance.

Maxiz, you should be fine using the coils you got

I call bs till you provide us some data. not some thread with spotty info.

Lots of us have upgraded and noticed a difference.

For everyone in this thread saying they saw a difference there is someone in that thread saying there isn't one.

I provided data, but haven't seen any data to prove the 2.0t coils are better, just opinions.

If any of you can provide me with actual data showing an improvement I would love to see it, but until then, I'm going to go with the people who have done comparison tests and found the coil packs to be identical.


Just out of curiousity, how many of you have compared NEW 1.8t coils to NEW 2.0t coils? And how many of you replaced your existing 1.8t coils with 2.0t coils when you saw the improvements?

[walky_talky20]

There are 2 different options here for the taller coils, the ELDOR coils (red "R8" coils: 06E-905-115E or black version: 07K-905-715F) or the BOSCH coils (black with plastic covering the shaft: 06H-905-115B).

In my non scientific testing (pulling the coil off the plug and seeing how far it jumps), I think the BOSCH coils are superior. I am quite certain they are not "the same" as the 1.8T coils. They are a completely different manufacturer and a different looking part altogether. I would like to see somebody actually testing output voltage capability of a new R8 (06E) coil and a new Bosch coil (06H), compared to a new 1.8T coil (latest 115D).

[MetalMan]

I'm running the latest black-top 2.0T coil pack, PN 06H905115B, Bosch as walky mentioned above.

Personally I haven't tested spark capacity of these vs. stock AWM coils. I have run a gap of 0.044" on my current coilpacks without misfires on NGK BKR7E. Can't say I tried the same test with new AWM coil packs.

[walky_talky20]

Also, it should probably be mentioned that at least the ELDOR coils can be made in several different places. There is production on the red "115E" part number in Italy and Turkey, and probably Brazil, too. It is certainly possible that there are performance differences based on their origin. The ones from Italy could be amazing and the ones from Brazil could be a joke. It's difficult to say.

[Seerlah]

^That is because they will blow out.

OP, don't listen to that guy. He is incorrect in not just the spark, but running the awm coils. You need the adapters for the aeb valve cover. Your valve cover is not designed for push down style coils. You need the adapter plates, which will push space out the awm ignition coils. You can try pushing the boots down. If that doesn't work, you need 2.0 coils or rig up something so the ignition cpils don't wobble.

So you have tested NEW 1.8t coils against NEW 2.0t coils? Not 1.8t coils that have been on the car previously compared to new 2.0t coils?

Wasting money on what?

[walky_talky20]

I think I can do this. I have a couple brand new 1.8T (115D) recall coils. And I have a couple brand new R8 (115E) coils. I think I can get a new Bosch 115B coil from my brother. Then test them with this guy:



That will give me the air gap measurement that each coil is capable of crossing, which equates to a certain voltage.

[DoesntCare]

Wasting money on what?

The Adapter plates to run taller coils. $80-100 for adapter plates as opposed to picking up a push down style Valve cover from a junkyard or classifieds for $20, and a $20 VC gasket.

Or for people with AWM engines, no cost at all.

Would love to see the results of the tests Walky.

[Seerlah]

I run them on the awm with no adapters. Just manipulated the boots. Nobody cares about the adapters. Point I was trying to tell OP was he can't run awm coils on his aeb valve cover. I too think the adapters are a waste. But in some cases warranted, like in the OP's case. Or when people simply want a cleaner look, where they can enjoy both function and form.

I too am interested in the results for the above experiment. But being able to make a gap larger than .04" should be a clear indication that the spark is greater. That will never be able to be done on the 1.8t coil because it will blow out.

I for one have never came across a thread of people experiencing spark plug blow outs with 2.0 coils. Only time I did was when people ran too big of a gap. Not all cars are created equal, both mechanical and electrical wise (ie short creating drop). But even then, they were still able to go at least .04". That simply can't be done with the 1.8t coil.

For the sake of science I have an unused Beru AEB coil that you can use for comparison if you want 058-905-105/47. I've had it for years before I switched over to the useless, waste of money 2.0 coil conversion.

[maxiz1]

Here the comparison between the AWM and the AEB coils:



Here's the fitment over the valve cover:



As you can see, it fits nicely without leaving much gap on the surface. I agree that due to this, an adapter is not possible. My only complain is that it is not perfectly straight up vertically, but rather inclined to one side (left from picture). Is it just my valve cover is out of alignment or everybody else has the same issue? If the latter is true, how then you could install an adapter for the longer 2.0t coils since I believe the adapter hole is at the center?

I'm also interested in walky's test, especially comparing the 1.8t AWM coils at larger gap.

[Seerlah]

Keith, I have brand new r8 coils laying around as spares if you want one for NEW testing.

OP, the awm coils don't wobble? The boots are to hole them in place in the cylinders. If not for those, they will most likely dislodge themselves from the spark plugs. As for the slant, this has been known for a while. Far as I know, it is the black tsi coils that had issues with splitting. But later down the road, that was found to be unrelated and a manufacturer defect. They have been updated since then.

[maxiz1]

Seerlah - i didn't manage to test it while the engine is running coz i haven't completed the wiring. But it does feel tight and firm though. I read in some other thread people reported not having the adapters without any problems. I did bought a set of touareg adapters however I think I may not be using them coz they feel very cheap and could easily break.

[Seerlah]

That is for push down style valve covers. You have a bolt down style. Just because it is seated on the plug firmly does not mean it is planted in the cylinder firmly. Your engine moves a lot. This will cause the coil to make it's way off the plug after a while if not firmly planted on the actual valve cover, and not the spark plug.

[redline380]

Why doesn't OP just pick up a push down valve cover?

[walky_talky20]

Keith, I have brand new r8 coils laying around as spares if you want one for NEW testing.

Thanks for the offer. I do have new ones, though. And used ones. Would be interesting to see the difference, actually. I think my current R8 coils have about 100k miles on them. Man, I stack miles on this car!

[Seerlah]

Why doesn't OP just pick up a push down valve cover?

That was suggested above by doesntcare. He would need to cap off the rear breather port. Or add a vented catch can to it. Or...just dump it to the ground.

[maxiz1]

Unfortunately in my country, they don't sell B5 with push down VC so I couldn't find it in the junk yard. Importing through ebay would cost the same as getting the billet adapters. Plus, I would want to be able to swap the setup back to the original, in case this upgrade is not that reliable compared to the OEM setup.

[redline380]

Which country is that? There are other cars out there with a cover that could be used

[Davdraco1]

This is what I did. Put s little 3/4in breather filter on the VC and used one of 034 adapters for the crankcase.

[maxiz1]

So I managed to make my own hold down brackets with a piece of aluminum flat bar. Cost next to nothing but took around 3 hours to do it. Thanks to redline380 for giving me the idea.



As you can see near the firewall, I've used a connector instead of wiring the coil plugs directly to the harness. This is so that I could swap back to the original harness if I don't like this upgrade. My original harness was similarly modified:



Still have the ICM connected:



Not!!! I bought a chinese knock offs from ebay and hacked the internals:



Started the car and it fired up right away. I didn't notice any performance gain since I didn't re-gap the plugs as the coils are designed for 1.8t. I'll save money for a couple of months to get the 2.0t coils anyway.

[maxiz1]

So after 4 days of running the AWM coils, I feel I don't like them. Apart from the disappearance of the random slight misfire that I was having at idle, everything else seems to be a little bit worse. Car feels slightly heavier, and fuel consumption kinda increased 10-20%. I have switched back to the original setup.

So I guess the 2.0t coils is the way to go.

[OverSpun]

I upgraded to the red R8 coils a couple years back and they have been running well. IIRC, they have higher Ohms which is better. I cant remember exactly where I found my research to decide but I think this shows part of it. - http://www.golfmk6.com/forums/showthread.php?t=45050

Judging by that thread, R8 coils are the way to go, not 2.0t


I'm curious of the secondary resistance of the 1.8t coils vs what they show as stock for the 2.0t
