N52 stalling problems

Garbagio · 11-05-2021, 01:04 PM

Hi guys, sorry if this has already been solved, but I’ve been lurking in here a while and not been able to find a solution.

So my car started messing up a few months back, first it would be a little hiccup at around 3000 rpm, like I tapped my brakes for a split second. It slowly happened more and more often until finally it threw me into a DSC limp mode.

I replaced the crankshaft sensor when that gave me a code. When that didn’t work I replaced the camshaft sensors because those codes were being thrown, that didn’t work either. I read that it might be my vanos solenoids so I replaced both of them and that hasn’t worked.

What is happening now is that my car will be fine on startup and will drive for about 10ish minutes or until the oil heats up. It will hiccup, like for a split second there’s no fuel and then the car makes up for it by sending too much fuel. If I’m not in neutral, it feels like as I’m driving that I jam hard on my breaks for a split second, or the car will just shut off even when I’m in gear and I lose power steering and acceleration. I would deal with it if it didn’t do this at highway speeds.

There is one time when the car will run okay, if it stutters enough without stalling it will kick into the DSC limp mode, where I won’t have much acceleration, but at least the car runs. This makes me think this is an issue with a sensor and not necessarily any mechanical problems. It’s also kind of hard to get a code, unless it goes into DSC mode, when it stutters it will show an SES for a split second before going away, and that disappears if I shut the engine off and turn it back on.When I do get a code it’s still showing camshaft sensors, crankshaft sensor, or both.

Have I just been really unlucky and got crappy sensors from oreillys this whole time? I’m just mad that I’ve sank a lot of money in this car and I can’t even drive it safely on a highway.

Thanks for your guys’ help
