Problem with BMW 320d e46

[320BMW]

Hello everyone, so first of all, let me explain the problem im facing with mt car.
So when i'm trying to move on a hill with a handbrake, the car moves a little bit and its struggling to continue and to accelerate with the pedal on the floor, then i need to press the clutch to prevent the engine stop. I went to a mechanic, he replaced the MAF (Mass-Air Flow) sensor (Its from a VW Golf) , but there's only a little bit of improvement nearly i don't see any difference... Also I've googled everything and i see so many solutions, causes, like turbo lag, vacuum leak, fuel filter... I've bought my car 2 weeks ago and its really a good car, got a nice turbo whistle... If you have any solution, or what is causing this please help, because i really need this problem fixed asap

I don't think you're supposed to have any "turbo whistle" on a standard setup... that could be your problem. I'm sure someone with a bit more knowledge than me will confirm this.

Have you tried releasing the handbrake? :smilebounce:

Does the car drive normally otherwise, acceleration uphill? consumption?

Wait, let me get this straight. You put a Mass Airflow Sensor from a citi golf in your BMW?

You need to find a better mechanic who can correctly diagnose the fault and not randomly replace parts that have been stripped from other cars.

This.

Take your car to someone who knows what they doing.

Yep dude, lulz, im using it because i dont want to roll back
No it doesn't accelerate if i stop and move with a help with the handbrake.
Basically it stalls... Scanned it with a diagnostic tool, no problems found... dunno what to do anymore, hopw the Bosch pump and the turbine are good, and i think they are, otherwise they cost a fortune... :rage:

The a**hat fool put a VW Golf Passat MAF, and he said it goes well, i've paid 60 euros for nothing... But i've just cleaned the original one from BMW with a clean spray and i'll try it tommorow... Oh and by the way its a 2001 year model... if that changes anything... Thanks

I recall a post from Coisman - not sure if he used another source - stating that the innards from some VW MAF is exactly the same as some E46 MAFs. It was a significant saving. Perhaps the mechanic went this route? Without exact details one can only speculate.
