'00 320d - turbo failure ? emergency program ? WHAT ?

[Nick.se]

Hey guys,

I just purchased a 2000 BMW 320d (136hp) and ive noticed that when i accelerate just when the turbo kicks in, it "turns off" again after 0.4 secs, and ive got not check engine lights or anything.

Do you have any idea what the problem could be ? used:

It has driven 165000 km but is in good condition.

Thanks in advance.

Nick

Have you checked for vacumm leaks? Is all of your piping from the turbo to the throttle body nice and tight?

im not a mechanic, but i had a friend of mine look at it, and he said that nothing seemed out of place or anything...

Is it possible that the previos owner has driven the car so gently, that is has adjusted to his/her driving and just needs to be driven hard ? It could just be me, but i think its getting more responsive every time i drive it... either that or im just loosing my mind

Im having a mechanic friend of mine looking at it on tuesday... and putting a tester on it..... hopefully its nothing serious, that car seems in really good condition all way round... im really happy about my purchase... although i had to sell my S500

Thanks for the help so far Bimmerboy

describe this better. why do you say it "turns off" ??? do you have a sudden loss of power, if so at what revs? do you hear a whistle (waste gate stuck or malfunctioning? describe what happens.

some south african made motors had problems. whare was the car made?

It just looses the boost from the turbo, its just like if you switch the turbo off entirely, looses the boost it just had... (it kicks in at around 2000 rpm and turns off at 2300 or something like that) and the effect of the turbocharger just dissapears completely.... and the engine alone does "all" the acceleration.

I have no idea where its build. how do i check that ?

I can hear the turbo when i rev the motor in neutral etc. havent tried to listen when i drive...

But as i said before, no error messages or anything.

Appreaciate any help i can get.

this does sound like a faulty waste gate (valve opens too soon). any black smoke from exhaust? i do not knwo whether this triggers codes, certainly it does not have to trigger check engine light.

vin number, and a call to bmw will let you see where the motor was made. others on this forum may comment, cos i am NOT well versed in gettign the specs out of databases.
