Dsc is cutting power do to over heated brakes from hooning.
I've had this happen at an auto cross after a few laps showboating. Check dsc module for shadow codes |

I remember reading somewhere a while ago about diag not showing all the codes, some shadow codes are not shown and if you somehow make it show them the diag tree lights up in red with codes=) i dont know any details tho, but could be something to look into

Have you monitored coolant temps? Also as other have mentioned these cars have something that cuts power when the car thinks the brakes are too hot. Fro. What I understand it only monitors driving conditions not actual brake temps

i was speaking to someone and these piezzo injectors supposedly don't signal when they fail and inpa is showing normal levels even though they fail. johny bravo here had it...
other than that, there might be a countless of other myriads faults in vacuum system that's only detectable when you check all the parts one by one that nobody even wanna do coz it's hard to reach and pain in the ass to even check. you even have to remove the intake etc ....it's just shittiest car ever. that's it. get rid of it and buy some other car....just throw it away. as i said elswhere, majority of owners of this engine are driving with no full power and they are not even aware of it. even anothe guy here had perished vacuum lines he found and he said he didn'[t even feel it, because he probably don't know how full power feels on this shit, because it has never got one, or just lost it gradually. only handful of people are driving with full power which is really unfortunate. buy a petrol. they will ban diesel tractors pile of trashes very soon too in europe, because they are unhealthy craps, so get rid of it too and buy an 335i and you will get a sound as a bonus and u save on service too with similar fuel consumption....or my advice would be don't even buy bmw, they are terrible quality, chinese like build and it's time we stop buying them. go support new mercs that look nice, or jags, or porsches...and of course audis...all of them much better choices...bmw is shit, don't buy it. |

Here you went I thought you were going to give some useful information... Then boom

All your post just waste space... Boohoo my car broke... It sounds like a tractor... Oh your car broke! Oh these cars are junk boohoo.. I'm gonna get a non diesel cause it sounds like a tractor... Shut up and move on you are being the girlfriend that won't stop calling.. SMH 😂😂😂😂😂😂 Last edited by 335stoner; 08-24-2017 at 08:27 PM.. |

He should get a simple car.
Heck, my vw tdi had some annoying issues that came up... I love German cars but they can be complicated and finicky. Same goes for the 35i or whatever benz you want to get. My neighbor had her Benz in the shop more times than I can remember, but she leases it and maybe you should too or buy new and pay the big money. |
