Intake manifold flow flap

[bobalong135]

So driving along and randomly my car wouldn’t rev above 3000rpm and a check engine light came on with 2 error codes

1- was p10a4 Intake manifold flow flap

2- was p0033 turbo solenoid valve

Anyway turned the car off and on again and multiple times throughout th day and sometimes it will let me go above 3000rpm sometimes it won’t

The question I got is I’m looking into and was wondering what those 2 fault codes actually are? What do they mean and how to fix them?

Cheers

You don't say what car/engine it is.

You don't say if you reset the codes.

You don't say if the same ones came back.

You don't say if you have done anything about either or just switched off/on.

Engine is a 160bhp 1.4 tsi

Codes had been deleted and cane back within a few miles

Haven’t attempted to fix it yet as I my research into it hasn’t helped

They mean potentially there may be a fault relating to those 2 areas that needs investigated and rectified. Although that would seem a little obvious as the codes are pretty descriptive ?

So are either of those actuators operating correctly ? It's hard to see/test from here.

It currently works but then I can simply turn the car off and on again and it will go back into limp mode and not rev above 3000.

I know the error might sound obvious but what actually is it?

The fact the car won't rev above 3000rpm is likely because the engine management system has gone into a mode call "limp home". When it detects a critical fault, the engine speed and throttle angle are deliberately limited to try to avoid any more damage because of the fault.

In your case, it sounds like a boost control failure (turbo solenoid etc) that could result in overboost and engine damage, and so the system has gone into limp home to prevent that damage occurring.

I'd suggest you need to take the car to a qualified garage to have it inspected, the fault diagnosed and repaired!

It means the ECU doesn't get the expected readings back from the Intake manifold flow flap and the turbo solenoid valve.

Could be wiring, could be plug/socket, could be ECU fault, could be the actual item itself, as above we can't tell from here.

You need to do some basic wiring/plug/socket checks as a start & see where that gets you/what you find.

Alrighty gonna have to be something I research into a bit then

If only cars told you the exact problem and it’s location haha

Cheers guys

Are you asking what 'Intake manifold flow flap' and 'turbo solenoid valve' mean? I typed those phrases into Google and got pretty clear descriptions and drawings in the first page of results.

Yes, I agree, if only it would say something like Intake manifold flow flap fault, or turbo solenoid valve fault........ At least then you would know what the fault was.......
