Some serious problems on my 428i ! Hopefully someone can help me out !

kchung0618 · 06-17-2022, 07:15 PM

I start my car today and it sounds like not smooth as usual. And then it suddenly stalled on the highway in a traffic jam. Will it be a spark plug issue since I saw the engine shaking a little bit which I am not sure normal or not? Or any other issue it could be?
Ps. I have installed a VRSF charge pipe and a bm3 stage 1 91 octane tune recently. The cp was installed in a shop and the screw of the connecting part of 2 pipe was not tight enough when I am driving back home and they separated for a while. But I do not have tool to tight them back. So I drive it back to the shop and ask them to tight it back for me. (You can say there is no cp when I drive back to the shop) I know it is a bad move now and I just want to fix it.

My car currently has a VRSF dp, cp, injen air intake in the engine bay.

Did you pull the codes to see what the issue was?

Any leaks?

I cannot see any light on the dashboard. I feel like there are leaks from the charge pipe but the shop said no leak in there. Or should I go to another shop to check if there are any issues?

Sounds like a bad coil or injector.

Is it expensive to replace or fix it?

Before you replace anything, please pull codes. A coil isn't expensive to replace so you hope it's something "smaller" like that. But.... Pull codes!

Thank you. I will buy a reader for that.

There's no need to buy a reader, there are at least a dozen free apps that will do. You just need a bluetooth OBD adapter.

Wait.. did they fix the charge pipe or not?

I have bought it and read there is a code P00BD$07e8. I google it and it seems like related to mass airflow. I try to get to understand but I am being more confused.

That's what it appears.

You likely have a big boost leak. They didn't fix it

Fliplegend · 06-23-2022, 09:42 AM

Considering it's a VRSF, I would bet fitment is garbage and you have a leak.
