hi guys.....mi friend is having some power loss issues ...
the car drives ok and after a bit of hooning it cuts power....if he restarts the car everything is ok....inpa or ista d do not show any error....
if i clean errors while driving ...power comes back...

do you have any ideas....? car is remapped with dpf and egr off ....i loaded a stock map ...still has this problems but feels less marked ...


do you have any ideas ?

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

this problem appears also on "german" motorway cruising without braking at all

What are the error codes that you are clearing while driving?

[BB_cuda]

hooning is a new term for me.

[haty]

it does not show any error code.....just by cleaning with inpa....power comes back ...

Sorry, not sure what is meant by the term cleaning then, perhaps resetting adaptations? Not sure I can help, almost sounds like a maf or faulty injector issue, but I am no expert.

Cuda, think Ken Block in a 4 wheel drift, such act would be "hooning". He is considered a Hoonigan.

This is a new one for me.

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

[Torqu3]

Could be that your tuner is hiding certain codes form sight.

oh another power loss, i was dealing with too many with this tractor, i am selling a coupe for 10k euros in central europe. will happily get rid of this crap asap and will go for a strong petrol(not bmw) probably cayenne turbo s if i sell this pile of trash. ....this is not worth the constant hassle. wish me i sell it soon...
thanks to all and condolences to you in dealing with it

^^ I think this is a song for you......

[haty]

i also have ista D but even there no errors ....i loaded the stock map and it does not cut the power it just make inconstant power delivery ....

we tried to disconnect maf , intake temp sensor , bought new map sensor ...

no success for now ...

[335stoner]

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

[bayerischer]

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.

[335stoner]

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

You start crying like a baby

You have already stated that you are getting a different car, so if you can't bring any intelligent information then shut up and stay out of the diesel section... 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 😂😂😂😂😂😂

Lol. That guy with the failed vacuum lines knows more about this car than you or I ever will. Also, I told you to get a warranty because the vacuum system scared you. These cars are a pleasure to drive, as long as you know how to maintain them, which you don't. And you want to talk about full power, I'm putting 380hp and 813nm to the rear wheels. You've just got to know what you're doing and how to take care of the car.

Sometimes I wonder why we bother to even try to help clowns like this one.

[robnitro]

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.

[haty]

anyway ....we are not giving up

2 injectors were already changed due to previous errors..........and obviously all where tested....
