Can I ask what all comes in the BL kit? Is it coils an a harness and the rest is done in mhd? Are they adapted to fit length wise does it look or do they look exactly like an r8 coil?
It is an R8 coil. Straight from VW. You get a harness that's perfect in length, and very easy to install. Along with 6 coils. You reflash your map or BEF and check the bimmer life box. Done.

OP, did you run the PR coils with n20 plugs once all the mosfet issues were figured out? Not that it should be any real, noticeable difference but it looks like the plugs are the only other variable that changed, aside from the coils.

I did not. There was always a what if in my mind and I never installed them back on. They might have worked fine, but they had already left a sour spot to me and I didn't want to have to deal with it again.

Lots missing from this story, but glad it worked out in the end. Replaced all the MOSFETs for him personally, he never bothered to reinstall the PR coils again. But honestly there were so many things going on with his misfires, nothing was consistent. It would move around and I didn't even know he had broken a wire. Anyway, 1/100 isn't bad. Again glad it's working and glad I could fix your DME for you, on my day off, for free, so you can't complain about the service at least lol. And it was likely the issue all along with one mismatched MOSFET being previously replaced.

No I didn't reinstall them. I was to afraid to. And you repaired my DME, but it wasn't free. 83$ I paid Robert. And like I said they probably would have worked just fine, was something wrong with my car, I'm sure there was. I always happen to be the lucky one who has problems. I'm sure the coils we're perfectly fine. But just not on my car. Mosfet, injectors, plugs, coil. Could have been all or one. We don't know. All I was sharing was my experience with the different coil choices.

The only wire I broke was a plug wire. In which I bought an entire new set from Robert. The wires were all brand new.

I replaced them for free, you asked me to do the work and I did. But maybe I'll get Robert to cover my gas then since he charged you some. 99% sure it was the issue, but who knows. Enjoy your car man glad it's back up and running.

Yea he charged me. I appreciate you repairing it. But PR charged me. It probably wasn't. We will never know honestly. Which sucks, but i daily drive it 70 miles and I didn't have time to continue to troubleshoot.

Glad it is all sorted, we did charge $83 for shipping of DME to him, new mosfets, and shipping on the new mosfets (we shipped them express). I never told Justin any of this didn't involve him so he was unaware sorry he called you out thinking that we ate all costs on this.

The DME had a prior repair as you are aware and was done with incorrect part and we are confident that was the issue. After replacing all of your mosfets it appears your issue has been resolved. Shame you never installed our coils once we did the repair but you did put stock in and drove on them for a few days letting us know you no longer had any issues. Since his coils are working for you now and stock coils were working after the repair and our coils tested good when we walked you through testing them we can all only assume that the PR coils would have worked fine.

Point is as you pointed out we stood by your side and had outstanding customer service, we also helped make sure your car got back up and running in any way we could. The fact that you switched to BL Life coils is fine just glad you got back up and running. Sorry you feel as though our product could of been an issue if you would like a full refund just let me know we will gladly refund you all you have to do is ask.

Truly sorry for your experience regardless of the cause, just glad we were able to do what was right by you through the whole process ruling out our product as the issue. I believe that is all you were trying to point out here, not bash our product in any way but simply state that we went above and beyond for you but out of fear of the unknown decided to try Bimmerlife Audi coils.

No hard feelings and I know this wasn't intended to bash our product so just glad you have your car back running smooth.

antiochasylum, glad your car is back up and running. sounds like a nightmare. But damn that's some damn good customer service for V8bait to come in on his day off. props to that. it sounds like something was wrong with your car and the new coil may have brought it to your attention. either way its back and running. the install on the BL sounds so easy lol. not that the PR is hard. but I love the plug and play of the connectors. kinda wonder why PR didn't do the same? maybe to keep the cost down. but I can tell you I've broken a terminal for my DME already from installing/uninstalling JB4 so many times and that wasn't fun.

I also would like a pro/con list on the two types of coils. both sound great.

Thanks for no hard feelings. This is simply to share my experience. In no way was I meantime to bash anything PR or products. If your offering me a refund, that's great. Send it on.

I've dumped enough money into this car over the last month it's crazy.

Glad we could get the full end story, as they say, always two sides. Seems like PR gives godly costumer service, and seems like this car had a ton of ignition issues that weren't PR or PR's ignition kits issue. Glad OP is up and running smoothly, but after finding out you never put the kit back on after the fried mosfet, tells me that the chances are high that was your issue, not the kit.

Let me make one thing clear. In over 3 years I did not have a single misfire on 18psi. So to say I had a "ton" of ignition issues is way off point. Once I installed the PR set, a mosfet blew. And after that it was an onslaught of issues. Replacing with a different part number or what ever we will never know the exact reason.

Don't say an onslaught of issues when that was not the case.

Thanks.

Yeah no problem we are glad to stand behind our product and offer a refund. Just shoot an email to [email protected] and request an RMA # we will have refund issued within 24 hours after receiving the ignition kit.

OP where does the kit get its power from? Ground is easy but it appears to have a power lead

You went from worn out coils to brand new ones that produce much higher spark potential. Your old mosfets were probably just fine with old, weak coils. It's pretty much a given that your mismatched mosfets were the issue.

Had a few general questions asking about this, so here's my take from many I've fixed over the years. If there's one thing associated with injector MOSFET failures on 2007 (and only 2007) cars, it's misfires. A bad coil can cause it, running on an empty tank of fuel, old plugs, dirty intake valves etc. One thing that causes misfires, is bad injectors. OP had bad injectors, he pulled his plugs and had a few that were black and fouled. That's always an injector. An injector spraying poorly is asking for a miss, easily killing the defective MOSFETs in the MSD80.

Fix is to replace all the MOSFETs with upgraded parts from Fairchild that handle more voltage. Not just the bad one. They don't ALWAYS fail open, just usually, voltage can just as easily damage the gate as short it. The DME also has checks for these so it's best they all match. Whatever OP had his replaced with, was one I hadn't seen before. The datasheet for it was rated lower than OEM in a few places, not ideal, and it was dissimilar from the others. I wasn't 100% sure it was the cause as I've never seen this done, I always do all 6 with upgraded parts (also didn't want to drive an hour my day off this month to solder, I don't get many).

The fact is his car lasted to 9X,XXX miles and 10 years with index 5 injectors without having a failure while being modified. That DME deserves a trophy. Tune a car, blow a MOSFET. Swap to e85, MOSFET. Low on gas, MOSFET. Hell you replace a battery and the next day the MOSFETs fail. Welcome to MSD80. It's an easy fix/upgrade so do it right and get the upgraded Fairchild part or migrate to MSD81, or you'll have a headache.

Justin where do you source your mosfets? I've been using ones from digikey that are what I believe are equivalent but I'd like a better mosfet if available

You can PM if you would like..

Side note.. Got my turbos back from pure and still collecting parts. Hope to get started tuning in a couple months (nice cool fall weather aka boost season lol)

On a side note, I'm making significantly more power than OP

You're not allowed to say that with a stock turbos power curve. You're making "significantly" more power then no one.


OP, having gone thru one DME, damaging another I can honestly say I've been there and have sympathy. Glad you didn't give up as I'm sure that crossed your mind. Appreciate the time to write some feedback on the products / customer service of the vendors.
