Hey When looking at other topics, we should almost make a sound troubleshooting guidance. :-) .found allot on youtube (since i am not the only one recording)..and hence allot of solutions.. No i dont have any speakers yet. Hence it cant be that. Thanks anyway As mentioned earlier...it could be a loose cable ( which I doubt) or..the car was not used for a while, that some corrosion of some kind has taken place. All key elements (differential, brakes etc) are functioning well. So its a good guess we need. Also I like to know a bit what I am talking about when going to any garage. I will add your troubleshooting idea when finished...cheers

will do... i will also make a summary so people can use the knowledge if they encounter the same thing..cheers

Hey ik heb de link via Johan gekregen. maag ik morgen bellen? grtjs Eric

Ok. thx johan. I will give him a call. cheers

well its clearly not the: The fuel pomp (the sound is continuous and the sound wouldn't go stronger while driving harder) and fuel pomp I believe is on the right side back (when facing forward) The breaks since they got cleaned. Was tested turning the wheel and sound didn't come from breaks...or was very weak. Handbrake. The BMW handbrake is different to other cars. As you know its a specific cylinder behind the breaks. I did some tests. The handbreak is in good state and the sound it produces when driving 10km and pulled, is not the same sound I have heard. According to the garage: the differential is in a good state. its not the wheel bearings not the tires I am running out of options. These are the facts: The sound increases when driving above 30km/h and upwards Its a almost whining /metallic contact sound like Its behind the driver seat And I am not crazy..:-) The guy at the garage heard it as well. Actually two garages. Now my question is now Are there anyone in the neighborhood who is a BMW z3 fan and have some mechanic experience. Simply to create a diagnose.???

is practically the sound..then I have two questions if its the fuel pump: 1. would the sound get stronger once driving harder..? 2. and is the fuel pump behind the driver seat?

can that make the metallic sound?

yeah..i can imagine that,since its difficult to make a good recording ,its clear when you are in the car though. One guy did mention the gas pump..anyway...i need to go to a garage who have the knowledge or willing to listen to the sound...

seriously...you couldnt hear anything..pff..I give up..:-(

the sound is here..its clear after 16 secs..hope you can hear it though... http://soundcloud.com/eroche12/bmw-z3-sound-behind-driver

First of all I have to admit that the word hardy disk is new to me..but remembering the check at the garage...that disk if damaged would make the car shake which it doesn't. AM I correct? The shafts were checked and the sound is not typical for shafts. The reason I thought it would be the breaks was that the break disk had some metal contact (which can take place). The sound is indeed something similar. It really is located around the wheel and not any shafts. That we know for sure. We did raise the car and turned the engine on. Had the wheels turning and the sound could barely be heard near the wheel. Its only when the car has full weight and driving on the road you hear it.

furthermore, I did a small test by driving very slowly and use the handbrakes...the sound is not the same, so i believe its not the handbrakes

left hand drive hence behind the drivers seat. FYI its not the shock absorbers either...its kinda strange

thx... Its not the rear shock system since i have already taken care of it. Its a metallic sound, which gets stronger when driving...

First sorry to write this in English but the matter has become a riddle and difficult for garages to solve. So hence my attempt to yo see if any of you have an idea I have a wonderful Z3 which drives wonderfully. But has a strange sound behind the driver seat. A sound which is not wind not clicking, but a sound which sounds like a metal piece being touched. Its gets stronger when you drive harder. And the metallic sound is rather high pitched. I got my breaks cleaned and checked if it was the wheel bearings (wiellager). Also made a test to see if it was the differential or anything specific. The garage confirmed it wasnt the bearings or the breaks. Also not an differential problem. The only thing they could come with was the hand break system on wheel-system but they were not sure. It was a sound which clearly came from behind the driver. The people from the garage also took a drive and confirmed the sound. Anyone had this similar problem? Getting to a point where its beginning to irritate me and you can almost not listen to it anymore. All ideas are welcome.. cheers Eric PS All answers can be easily written in Dutch...

Hey Zoek iemand in mijn buurt die mij misschien niet allen tips kan geven maar ook miss antwoordt geven voor een paar vragen. Deze forum is heel handig maar soms is it een goeie idee met andere eigenaars te spreken. let me know grtjs Eric

Hoi Allemaal. Eerst bedankt voor de oplossing van mijn eerste probleem. Is nu opgelost dank zij jullie. Heb ook anderen goeie tips geleerd via de FAQ en verschillende doe-het-zelf handleidingen. Ik ben helemaal verliefd op mijn Mijn nieuwe of "oude" BMW z3..:-) Alles werk heel goed maar heb nog een kwaal, een bekende z3 euvel: suizende geluid achter (geen tik, dus niet de aandrijfas), maar de wiellagers. Ik heb niet echt speling constateert. Suizende geluid word sterker als jij harder rijd. Ik heb een paar vragen. Ik heb al veel studeert maar wil ff zeker zijn. 1. Heb jullie anderen ideeën wat de probleem kan zijn? en als wij eens mee zijn dat de wiellagers moet vervangen worden 2. Is dit een goed idee om de differentieel olie te vervangen? 3. Wiellagers achter onderdelen kost per stuk ongeveer 40 euro..en een garage vraagt 50 euro per uur. Dus is de totaal kosten ongeveer 200 euro? Dus twee uur werken? Alle suggesties zijn meer dan welkom. Durf namelijk niet zelf doen. mvg Eric

Morgen Allemaal Eerst bedankt voor jullie steun.!! Ik heb twee oplossing gevonden wat misschien is handig (of jullie weet het al). Een is de "temporary"oplossing en de tweede is de "100 % fix" 1. Teflon Spray. Alles wat is van rubber is gewoon te oud. Teflon zorgt wel voor een rustig auto. 2. Niewe onderdelen voor rear suspension. Alles wat is van of met rubber word vervangen. Kost? Voor twee sets (3 stuks) ongeveer 50 euro en montage 50 euro (1 uur), dus totaal 100 euro I heb ergens hier op de site een foto gezien met een lijst van alle onderdelen maar kan het nu niet vinden. Een deel is de Shock Mount, Rear Upper. Thx all Mvg Eric

TJa...oude gaarde...was een perfekte "pinch hitter". Net als Tomasson in karakter maar heb niets over hem gehoord in de laatste jaren...ik denk dat hij goed past bij Feyenoord..succes

Thx! Doe mijn best...:-)

Tja ..niet echt bang :-) ..nog niet...maar dan twee vragen...1. bekende probleem ok.maar gevaarlijk? end 2. Niet echt een oplossing maar voor min 100 is dat opgelost? Kan jij dit verwacht opgelost als jij zo een auto koopt via een garage? thx..:-) http://www94.homepage.villanova.edu/franci...ts_Roadster.pdf

Mijn vrouw was an het rijden..:-)..kijk mijn anderen reply
