BMW 530D Problems Boost

conor26021988

I have an E39 530D and am havin problems with the car loosin boost and goin into a sort of "limp mode"car drive fine until 60-90mph looses boost and stay dead then..sometimes after a drive power will come back but to be soon lost again..i have already replaced the boost pressure sensor and air flow meter????all the vacum pipes i have checked and seem ok any ideas????

Might be worth checking the fuel filter maybe or it could be a problem with the injector pump or could even be water in your diesel. Take it to a mechanic for your own sake.

What a bizarre thing to say!

a) What he described is a common problem on Turbo cars, usually a boost leak, stuck wastegate, f_cked FPR etc
b) Since when is a 2.9litre diesel "a mans car"?



OP: Get the codes read and limit the driving on it if possible, Limp Mode is there to Limp to the garage for repairs..

i used to have a subaru and it was a mans car these arnt regret buyin it and will be goin up for sale after only 8weeks of having it had nothin but trouble and v boring to drive but this doesnt help me with my problem doesnt matter whos driving problems still there...

I had a similar enough problem to that. Turned out i had a cracked manifold. Was leaking air as i accelerated. Could also be something completely different !

conor26021988

did it only loose boost sometimes or was it a constant prob and did it through up any faults?

pocketse

Didn't notice it on city driving but as soon as you hit the motorway you would notice it. Acceleration was gone. Was being overtaken in a climbing lane by a punto. No warning lights or faults displayed. Burning alot of oil though, back of the car was black. You could feel the air escaping if you put your hand over the engine and reved.

Subaru my friend is whats called a littleboy racers car AKA skangermobile ,BMW on the other hand (esp. 530d 2.9) would be classed as mans car due to engine size ,performance and generally being AKA "The Ultimate Driving Machine" with a reputation of been classy .

What have you been smoking today?

A Subaru (bearing in mind that's the brand, and not a specific car) a 'skankermobile'.
So, are Foresters and Outbacks skangermobiles? Or the current model Legacy's?

A 530D a mans car because of it's engine size? While I think it's a great engine, I hardly think it screams masculinity. My mother drives a 535D for god sake. :P

And ultimate driving machine? It's not even at the top tier of BMW 5 series diesels...
Maybe you just like the sound of a diesel engine... not me though...

(Edit: Probably shouldn't reply considering the post above! )

Semi related question to this. Ill post here rather than start a new thread.

If I was looking at this 530d what are the common issues/faults to look for? It seems cheaper than any other auto diesel 5 series ive seen.

I also know that this particular one was used as a taxi for a while.

E39MSport

6 owners !!

Edit: - There are recent threads on what to look for on these. Search 530d. At 100k which is what it has you should contemplate replacing the cooling system.
Mileage seems low for a previous taxi.
