The are supposed to start mailing them mid May, so should be pretty soon. I have an oil change in 4500 miles, I will just do it then.

So my car overheated the other day on the way to work (it yells at you and goes in serious limp mode). I cleared the codes and took off the tune in the work parking lot in 18 minutes and then of course I couldn't get the thing to overheat again. I had to go to Cambridge tonight to my boy's baseball game and it overheated right before the exit. The electric water pumps like to go out, mine bit the dust just under 60k.

After a freaking 2 hour wait for the tow truck, it is on its way to BMW Minnetonka to get a new water pump. Roadside assistance comes with my extended warranty, so out of pocket will be $50 for the whole deal, not bad. Car sure did feel slow without the tune in it!

Re: JET's 335Xi
 

Ouch, these things have so many issues it seems like, bummer.

Re: JET's 335Xi
 

Agreed, bummer for sure

Re: JET's 335Xi
 

Yeah, not making these things look that enjoyable anymore.

Are there better electric water pumps for these?

Re: JET's 335Xi
 

That sucks :(

Is the tune untraceable i.e. nothing for the dealership/extended warranty company to void your warranty over?

Re: JET's 335Xi
 

Agree, the issues are not catastrophic, but plentiful and nagging issues.
- Electric Water Pump failures
- HPFP failures (covered by bmw extended warranty to 120k miles)
- Injector Failures
- Spark Plug and Coil Failures
- Direct Injection carbon issues

Re: JET's 335Xi
 

German over-engineering at it's finest.

Re: JET's 335Xi
 

They changed the design of the Injector for the N55, hopefully they are better than the N54. But yeah... like most "performance cars" they are not a Camry! :)

Re: JET's 335Xi
 

haha dsm issues!

Re: JET's 335Xi
 

I knew going in that there would be some issues and I am convinced it is a German thing. I have worked with 2 companies that had engineering based in Germany and it was impossible to try and speak reason to them, they knew it all. It if was failing in the field, then it was user error.

I knew going in there were a few issues with the cars, but it is nothing major and a few have had redesigns. The N55 is much better than the N54 for reliability, which is why I went with that. The water pump takes an hour to change out, so not a big deal in the future. Easier than the timing belt in a dsm. It didn't make my car undriveable to the point of stranding me, but would have delayed me to allow it to cool a little and the water pump to start working again. It was under warranty, so I just let them take it away.

I owned a BMW before, so I am used to these issues. I still wouldn't trade it for anything else around this price. The ride and power are exactly what I want. Although I am looking at a stage 1 turbo. Looks like about 40 - 50whp more on the top end. Dyno results will be out soon. That should get me to my 11 sec daily driver goal.

Re: JET's 335Xi
 

Without the warranty, i assume it would cost quite a lot just for the part itself + the labor at a dealer shop. I am already planning to have MAP to do a walnut-blast-intake on mine when it gets 45K.

Re: JET's 335Xi
 

Car is fixed and ready to go, cost me $50 :D

Re: JET's 335Xi
 

Warranty kicks ass!! I just googled a "how-to" on the water pump, just the part alone costs $400

Re: JET's 335Xi
 

Well time for an update! I just ordered one of these up, they had a group buy for 15% off and I couldn't pass it up. Don't tell the wife! :D Stage 1 turbo good for `40whp over stock and much more than that up top. Will hold 17psi to redline now instead of 10.

The best part is they give you full credit towards their stage 2 turbo when it comes out! They are shooting for 500whp with that one. Still stock housings but a different turbine wheel too. Probably going to need a FMIC soon and possibly a Cobb AP.

Re: JET's 335Xi
 

Didnt realise these ran Borgs from the factory, good shit man and loving the stock housing uograde options and their ability to reach 500whp. Wonder if MAP is going to start dabbling into wheel upgrades. At what point does the xfr case and trans need some attention? Wonder if running something like the light or heavy shockproof in the xfr case would br beneficial.

Re: JET's 335Xi
 

Nobody has found the limits of the stock drivetrain yet. Stock tranny is reliable to 500 wtq and starts heading downhill fast over 525 with 550 giving you about 20k miles. There are upgrade options though.

MAP is already dabbling some. I have been trying to get them to do one for months and after I jumped on this GB then Chris PM's me on FB :P These guys are on rev 2 and holding 2psi more up top that the other stage 1 out there.

Re: JET's 335Xi
 

Very nice, Def. want a N54 in the future.
What are dem fancy do-hickeys on the turbo?

Re: JET's 335Xi
 

The black boxes are the BOV and wastegate, all computer controlled :P

Re: JET's 335Xi
 

r u going to install it yourself?

Re: JET's 335Xi
 

Those Borg turbos with the integrated BOV and wastegate are sweet, if my turbos go out I'll probably switch to those.

Re: JET's 335Xi
 

Image doesn't seem to work for me, can you post a link to ehatever you bought? I gather it's a turbo but it could be some kind of elaborate bacon injection system?

Re: JET's 335Xi
 

No idea where the turbo pic went!

Re: JET's 335Xi
 

Damn that is sexy!

Re: JET's 335Xi
 

Whats that fitting on the inlet for? Just a dowel for alignment or actually serve some sort of functional purpose?

Re: JET's 335Xi
 

Looks like where the intake pipe bolts on.

Re: JET's 335Xi
 

I believe that is a threaded stud to hold the intake on.

Re: JET's 335Xi
 

Finally got a chance to work on getting this turbo on. Holy shit this is a bitch! I would take a turbo swap on the rustiest hacked together DSM over this. Finally got the damn turbo out after 4 days and the fittings were a big part of the problem. All of them were seized in the turbo. The car is a 2011, but is driven winters. I was pretty shocked it was that bad. Nothing else was corroded very much, just tons of shit to take out and most very hard to get to. Got it out tonight and started to get it back in place. I was hoping to be done tomorrow, but I doubt that will happen, probably Friday night. I need to get this done and started on the painting project.

Re: JET's 335Xi
 

:(

Re: JET's 335Xi
 

Its a german car what do you expect lol

Step 1 f or any repair: remove engine haha

Re: JET's 335Xi
 

While you are at it, gonna upgrade any other parts? Have you guys experienced any of the radio-buzzing issue in your BMW? It happened to me twice within a day last week. Upon researching, it is due to a defective radio head. Like GoodHart said, it's a german car thing!!

Re: JET's 335Xi
 

The turbo upgrade is my only immediate power plans. After I get my wife's truck painted I will put the spoiler on my car and paint the fender reflectors. I will probably put on the new diffuser also, but the front splitters will probably wait until spring because I am worried about snow ripping them off or cracking them. I may say screw it and toss them on because I would love to see it done. I think this will be it for visual mods.

Next year I will put a FMIC on in the spring probably. I would love to do DP, but I am worried of the warranty implications with that. That totally gives away that I am tuned because it would throw a code otherwise and that would basically void my whole warranty. Not sure I want to go there yet. I might be tempted to put on a 100cell catted DP. Should be little restriction and still not cause O2 sensor issues. Stage 2 Pure turbo should be out by then too, so that may be an option. One thing I love about Pure is that I get a full credit for my stage 1 towards a stage 2 if I send them my stage 1 back. How cool is that?!?

Re: JET's 335Xi
 

That's really cool they give you 100% on a upgrade exchange.

Re: JET's 335Xi
 

Let us know what you think after running the Pure Turbos product for awhile. I thought about having them upgrade my compressor wheels, but the price was so low I was a bit skeptical on their product quality.

Re: JET's 335Xi
 

any update, buddy ;-)

Re: JET's 335Xi
 

That's awesome about the trade in policy.

Re: JET's 335Xi
 

Back went out twice trying to get this turbo in. It is a bitch with the AWD system in the way. Turbo is back in, all lines hooked up and water pump went back in last night. T-stat housing hose has to go back on and mount the T-stat housing, then it should be easy after that. Hoping to get it done late tonight if my back holds out! It got a little pissed last night, but it isn't too bad.

Re: JET's 335Xi
 

Don't kill yourself.

Re: JET's 335Xi
 

Just curse zee germans more and more and it'll eventually go in. Good luck!

Did you ever get this thing on the dyno for some before/after action?

Re: JET's 335Xi
 

Damn near got it done last week, but back got tweaked again. Was out of town all weekend. 1 tricky part left to go on, then easy hoses to hook up. Should have it done Tues, have a chump car meeting/working session/drinking team meeting tonight :D

Had it on the dyno once, but had a bad boost leak so I don't have any good numbers to compare it to. Should gain 30-40whp, but the important part is that it holds boost up top much better. Seeing gains of 80+whp at 6500rpm. They still fall off some up top, but not nearly as bad. I will probably end up going stage 2 next year and that will be as far as I plan on going (upgraded turbine wheel too). I wanted an 11 sec AWD daily with some luxury, handled well and drove like stock. This stage 1 will get me close, stage 2 will be well in the 11's.
