You bleed it by turning the wheel right & left to full lock a couple of times, simples!

More likely your pump is goosed.

Hello thank for the reply do I turn the car on take off the resivior cap and then do it. If I try to turn the wheel without car on it's too hard I will need to raise the car

You need to have the engine running, otherwise the pump won't be operating.

I'd take the top off the reservoir as if it does expel some air you'll need to top the fluid up.

I'm not sure if the E90 has a central jacking point at the front, but that's academic unless you have a trolley jack.

If you can't turn the steering from lock to lock a couple of times on a solid surface, you could try to do it on a less grippy surface - maybe gravel, or wet grass!

Unless you have changed a component on the power steering system, or the fluid level has got very low due to a leak, then I doubt you have air in your system.

Has it suddenly became heavier the normal or have you just noticed it feels heavier than other cars you have driven?
