Limp mode at the track.

You have to order the "M Sport Package", which includes the "high speed package", which includes the oil cooler and the raised top speed limiter. A lot of the 135's don't have it.

Fair enough but guess I should've asked what 135i doesn't come with one?

Does the M Sport Package not come with the blackline trim? So any 135 you see with chrome trim does not have one.

Did you run only one 20 minute session? My first session was ok too. It was the second session that gave me problems and got much worse after that. According to your sig. you have ETS FMIC. Are you sure you lost your power after 10 laps due to heat soak? I used to have heat soak with stock intercooler, but since we installed Helix unit, i dont really have that issue any more.

I ordered my car with sport pkg, so it came with oil cooler.

I was under impression that every 135i after first year or so was m-sport. Isn't that like saying which 135i doesn't have m-sport suspension?

Nope. Only if you ordered the "M Sport Package" with the seats and trim packages, or, in the US, the "M Sport Package" or "Sport Package".

They all came with the Sport Suspension as standard, but not the raised top speed limiter or oil cooler.

To the original OP, installing the upgraded 1M fan from the PPK2 may help with the heat soak.

Although, it is more than just the fan and shroud. It also includes much better wiring, relays, etc etc etc for the higher current draw.

Ok. I will look into it. Do you know part number and where to order it from?

Cobb stage 1+fmic. No other power mods. Oil- Mobil1 0w-40. Ran with COBB tune at the track for the first time. Was looking forward to it, because the power gain was impressive, on the street that is.
First session was great, passing every car in front of me , no problem. Oil tempr. was at 270, which is ok for my car. Second session starts, and in a few laps i feel loss of power coming out of corners, my DCT upshifts waay before red line(i always drive in manual mode, street or track), car feels sluggish, oil temp is 270. No warning signs, or anything on the dashboard. After one lap cool down, car comes back alive, but only for one lap, and it goes to limp again. Next session got even worse. I had to cut my day short, didnt want to hurt my engine or trans., but i am very disappointed right now. Never had any of this with stock power.
Anyone has similar experience? Should i detune it for track days

If your car went into limp mode, the engine threw a fault code that kicked it into that state.

If it's a mechanical code, go fix the issue.
If it's related to your tune being inappropriate, go back to stock maps.

It's really that simple.

But don't automatically assume it's one issue or another, go look it up. I kept getting boost leak code (30FF) for multiple events until I finally went and pulled apart my whole intake system to find a missing o-ring from an idiot garage I took it to. Fixed that and the issue was gone, tracks no problem (minus the bad o2 sensor and broken fuel filler line), but at least I know what my issues are. Go get a scanner or go to a reputable garage and analyze the failure before jumping to "corrective" actions.

Sorry, no idea. I bought a PPK2 for my car and it came with the kit. Along with a crap load of other parts to make it all work.

'13 N55 w/DCT here. Just had my first HPDE this past weekend at CMP down in Kershaw, SC. I ran 8x25min sessions w/JB4 (+DP, CAI, CP & axle back) and had zero issues all weekend. I ran map 7 w/100 octane the first day then map 2 w/93 the second. Like others have suggested, read your codes bc AFAIK the N55 doesn't have known limp issues on the track that would explain what happened in your case. I'm interested to know what you find out.

Sucks though to have that happen on your first track event, sorry it happened to ya!

2011 135i DCT. ETS intercooler and PPK1. I run 70% water to 30% coolant and a bottle of water wetter. Two track days at the autobahn this past week. Temps hit the high 80s. Oil temps maxxed out at 270. Felt no loss of power and of course no limp mode. I run intermediate and was driving pretty hard the whole time on both days. I use German Castrol 0w-30.

Its not that simple dude.
My COBB accsessport tells me that no codes found. There were no warning signs of any kind on the dashboared before, during the track sessions or after. Do yo know any other way to check the reason of power loss. I have no power loss on the street.

Cobb stage1+FMIC is running more boost and is more agressive that PPK. So, i would say you made the right decision for track duties.
Do you leave 70/30 ratio of your coolant for the winter?

No, I reflush to standard 50/50 around fall. Car is stored during the winter. I find it has plenty of power at the track. The limiting factor is my driver skill not the lack of power. I have had plenty of drivers tell me after a track session they were surprised how fast my car was on the straights.

I have surprised other drivers many times even with stock power. This car is fast in the straight line right out of the box, and with right susp. mods is very fast anywhere. I have e92m3, now i am modding it for the track too, but i actually prefer 135i, its more fun to drive.

UPDATE!!!
I was driving this morning to work, and all of a sudden, even before engine oil reached the operating temperature, i see yellow icon on my dash that indicates engine overheating, i lose power and yellow icon turns red. Cant go faster than 20 mph. Limp mode. Stopped the car, let it cool down for 5 minutes, start, go and the same icon comes back in 10 seconds, limp mode.
Luckily i was only 1 mile away from my bmw dealership and i somehow limped there. Fortunately i had my Cobb accsessport with me, so i uninstalled the tune while i was stopped for cooling.
So, all signs point to water pump problem, and my car is out of warranty since the end of april 2014 I am waiting for a call from my SA to tell me what exactly is the problem. I will report back.

Having this happen so close to warranty expiration blows. But then again, I heard the WP is considered as a wearing item, ie , not covered by warranty.

How much mileage do you have?

[Groundpilot]

Its a little more than 35K miles.
I was able to pull this code before i dropped it off at the dealer ECU P378F. Anyone knows what does it mean?
