Well I am happy to say that after talking with Arric at JMTC he was able to figure out exactly what was wrong with the boost issue. Aside from simply making too much boost, there was an issue with one of the coolant lines causing the wastegate vacuum actuator arm to bind and the wastegate was not operating properly. The guy is smart, he did that over the phone while I was driving! (Bluetooth of course). Bottom line: I am very Impressed and a very satisfied customer of JMTurboCoopers!

My other issue unfortunately is still here, my dandy new Schwaben tool cleared everything except the airbag/restraint system fault. Which tell me that the fault must still be active. I’m getting a 93C8 code that says it’s the drivers side forward control. I’ve been trying to figure out where that is and if I maybe bumped or unhooked it accidentally or something. Or if it had to do with unhooking the battery when I was working on it. But I can not find that info anywhere! I don’t think it’s the one under the seat (but could definitely be wrong) the closest I’ve been able find is for an R57 that says that US models have an accelerometer behind each headlight.
Now I did remove the lights when I fixed it, that’s a possibility that I will look at in the morning.
But if anybody has any suggestions or advice, please, I’m all ears!

 

On the plus side.... I HAVE BOOST!!! I think the turbo has been toast since I bought the car. A few months ago I threw my iPhone boost gauge on it and under extreme acceleration I maxed out at 6psi !! What a difference now!, I’ve got it adjusted down to where I’m topping out at about 17psi now, which is way better than 6, or the 22+ at 3200 RPM I was getting yesterday! It’s a totally different animal now!

 

It’s alive!

 

Well, I watched the video. It has some really good info on how it works. After viewing, it does sound like my problem may very well be that I’m just making too much boost right now, which was what one of the codes indicated earlier when I had a local Euro shop check them for me, that and a miss. According to Arric on the video one of the problems you may have with too much boost is a miss over 3000RPM.....hmmmm, so I had a miss at higher RPM, an high boost code, and crazy boost venting...! Well, tomorrow afternoon I will go pull the heat shield off and take a look at where it is and give it a little adjustment and see what happens. I don’t think I’ll hurt anything by turning the boost down a bit! Just not up more, lol. Threw another code tonight, but I have no clue what it is. My cheapo scan tool won’t read the BMW specific codes. But I do have one on the way that is supposed to do everything I’ll need, including registering a new battery. That alone should pay for itself (almost). Heh. I ordered a Schwaben scan tool from ECS Tuning, does anybody have experience with one? It is supposed to be here on Wednesday.

 

That’s where I’m leaning now as well, I spoke with Arric at JM Turbo Coopers, who I got the turbo from. The upgraded turbos are probably set up more for someone with a tune, which I don’t have. I think the issue is simply too much boost! I makes sense and fits all of my symptoms. JMTC has a video on how to adjust the wastegate on their turbo and a bunch of good info. All I need to do (I hope) is adjust the wastegate to turn down the amount of boost being produced.
I’ll know in a few hours when I can get to messing around with it.

 

Good! I read a lot about it, and several folks at NAM have them. Looks like with the fact that it can also register a battery, I think it will pay for itself real fast! Thanks for the personal input.

 

That’s fantastic, thanks. I can not wait for it to arrive.....at least tomorrow isn’t far away, lol. I read that it can even do some basic coding for some functions....but I’d be too nervous to mess with that!

 

Update: Well after doing some research I found out that the US versions of MINI’s have an accelerometer on the frame rails under the headlights. Since the lights came out when I put the car into the service position, I thought what can it hurt to work backwards and see if I screwed something up. Well..... I DID, lol. Just went out and pulled the headlight on the drivers side and started poking around in there. Guess what I found almost immediately? A loose plug hanging there! Located the sensor, plugged it in and buttoned the car back up.... started it and ....... NO LIGHT!!!! I can’t believe it was such a simple fix for my own dumb problem that I apparently created for myself, lol.
Thanks Everyone!!!! Mike is not Grumpy now, lol.

I laughed so hard at this!
Thanks!

 

Well the new turbo came with an upgraded one with a bit stiffer spring, but when I took it off, it just feels like it’s not working right compared to the old one, it did help just a bit when I switched them. I guess the next step would seem to be to maybe swap the springs so that the stiffer one is in the old DV? And see if it makes any difference. Arric from JMTC just emailed me back and suggested that it could be something as simple as the set up, they have a video for how to adjust the wastegate to where it should be, I will watch it and then go check mine out. But that will probably have to wait until after I run the Grumpy Wifey to a Dr appointment in the AM.
Thank you!
Please don’t hesitate to add any additional thoughts or suggestions.

 

Is it pretty pain free with The Schwaben?
