I've also established a good rapport with my SA, parts department and dealership management.

I've tried everything, everyone denied me bcuz I still had my intake in there. There's nothing I could really do, I keep getting the same answer. Over boost and over rev, blamed the intake

Ok so seems I was on the right track about the intake being the main reason they are denying vs the DINAN tune?

Sorry to hear your bad luck.
For what it's worth....
Bought 3+ BMW's from Ottos (and will continue to purchase more) and had nothing but exceptional service.
Kevin is a true stand up guy and went over and above to provide me with exceptional service time & time again.
Must be a legitimate reason why Dinan doesn't offer a intake for your car...

Do you think the intake can cause over boost or over rev? I don't think so. I guess +4psi is too dangerous for N20? Maybe.

I think the combo is untested. Perhaps something else wrong with his engine, some other issue, and the intake + more boost exasperated that issue.

Yet from a dealership point of view, the intake seems like an easy scapegoat. That's my point.

Also I believe the N26 is a SULEV which IMHO would not be suitable for an intake.
Like I said it's
IMHO.

Oh my...now I'm nervous. I got the Injen intake for my 2013 328xi N26 and was going to install it this weekend. Not to mention I also got the JB+ piggyback as well. *hand wringing*

The N26 being an SULEV really has nothing to do with it. The N26 is almost identical to the N20. What makes it SULEV is mostly emissions related equipment (secondary cat, more restrictive primary cat, etc).

An intake can cause a lean condition in any car if the computer doesn't compensate for it. The MAF should detect the increased airflow and adjust fuel as needed. I'm sure the combo of the intake and S1 tuner caused something to go haywire with the AFR. Now what it wouldn't have caused is an over rev condition. That's the part I don't get.

There is something missing in the details of what happened here. And if there isn't, then the takeaway lesson is remove your mods before taking your car in for problems.

I've got an Injen and intercooler on my N26. I've got the DINAN sport tuner showing up tomorrow and I'll be installing it. I will also be monitoring my car for ANY hiccups.

Was going to order it for my n26, i have a dinantronics sport coming Monday tho.. little iffy to go further.

[rixride]

I was told by a BMW tech that the BMW dealerships are telling customers to remove aftermarket intakes on the n26 engine.
This is not confirmed but you might want to check with them before you plan on installing one.
That is if you think your warranty might be in jeopardy.

[gpchamp]

I have a Dinan Stage 1 and a Remus Responder. No issues whatsoever.

[bheng89]

off topic but novice question to you guys that understand more about the n20 engines.

I am looking to install the Injen intake but should I be monitoring AFR with an OBD II reader if I don't plan to have a piggy back? I would not like to walk down this path any time soon but wouldn't mind do smaller mods here and there

[LaCross]

Any update as to what happened?

1.2-1.3 bar stock? complete BS, you ever logged this car? its 1.05bar max at midrange or 1.1bar if weather is hotter.

[D041987]

Boost is tapered by gear on our cars so 1st gear you are looking at around 11psi, 2nd gear around 13 psi, 3rd gear is around 15, and 4th gear you are looking at full boost around 17 psi max!

Also Intakes do not cause engines to blow up on a turbo car, so get that out of your head. You got a MAP sensor to measure the pressure and a MAF is like a secondary to help smooth out the driving and the air is going into the turbo not directly into the engine as this is not a N/A car. I been running intakes on almost any car I have owned. This Engine has flaws, and I bet you had a oil pump failure that cause it to "Over Rev" which is fancy dealership words for running the bearings dry on your crank due to lack of oil pressure or you had a rod bolt stretch. In either case your motor needs a full rebuild.

[madmortar]

Either way, OP got fucked IMO

[CalCarNut]

Over rev could easily have just been playing in M(manual) mode and revving the snot out of it without paying attention to rpm/gear selection.

[D041987]

But that is why we have a Rev limiter. Engines are designed to be revved even higher than the set limiter and that is in place to keep all the internal components happy for a long time. If there are components that fail internally that is a manufacturing flaw and BMW should own up to it's issues regardless if in warranty or not and especially if the car hasn't even gone past 100K. Most designers of modern engines strive for the engine to last 250K+. Now he does have an early production year BMW so that is even more in the line of having a bad batch of engines that some including myself have experienced with failed internal components.

Also if this was caused by the Tune then Dinan should step in and help out the poor guy bearing he is only a few thousand miles out of warranty. But we all know everyone is money hungry so they well tell you to go pound sand!

[CalCarNut]

Does Dinan remove/increase the rev limiter? Doubtful...but...

I got my Injen intake installed over a week ago and it seems to be running fine. Love the sound regardless of anything else it promises. Instructions included could have been a little clearer though. Thanks internet!

I'm also running the injen intake but with dinan sport tune at +4 psi (race). No issues so far and crossing fingers!

Did you ever run into issues on your N26? I have my Dinan Sport coming tomorrow. Not going to install an aftermarket intake.
