Couple Of Problems Need Help With

[Sam528i]

Hi all I have a

E39 528i sport with all mtec extras

Now it drives spot on tracks straight and don't pull when braking but my problem is every now and then when slowing down I get a loud click type tap noise from front of car quite loud and happened once when turning on full lock

Any ideas?????

Also when first started on a morning the engine seems to run sweet then revs seem to drop right down and back up again not constant but every 20-30 seconds buy when engine up to temperature it's fine and does not fluctuate at all

Any ideas ??????

Many thanks in advance

Check all the bushes and suspension legs. Ball-joints too...

As for the idling, why not give the intake and throttle-body a thorough clean... ICV too ?

Cheers mate will jack her up and have a look see what I can find as for the idling I shall whip it all apart when get time and give it a clean only seems to do it till up to optimum temp

[Guest Mister Dabsy]

Idle control valve (ICV) then ?

[Sam528i]

Shall look into it mate and update this as I go

Anyone have any ideas on noise seems to do it every time I press brake to slow down

Does not affect drive of car or does not affect braking in any way

Just get a loud click (single click) as soon as I start to brake /decelerate

Does not do it when pulling away only when slowing down and will not recur until I have accelerated and pressed brake again

She is a 2000-X bmw 528i sport mtec ( she has all optional lowered factory sports suspension etc )

Any ideas ?????

Not sure without looking but maybe a split balljoint?

[Sam528i]

Thanks mate shall have a look when get chance it don't seem to affect drive of the car just it's quiet a worrying sound

[Guest Mister Dabsy]

Sloppy brake-pad I think :huh:

[Sam528i]

Cheers dabsy will have to have a nosey

What would cause that then???? Excuse me if i sound thick now haha

[Guest Mister Dabsy]

Nothing sinister, maybe the caliper-piston "relaxes" more than it should ! :huh:

Does it do this when releasing the throttle (without braking)? If it does then it could be some give in the transmission/shaft/axle, otherwise don't worry...

Cheers daisy will check again when drive it in the morning and update here. Think it's just when I brake but will let you know
