Z4 Rattling : Broken Spring?

HEADRAT · 19 Mar 2009 at 14:31

Hi,

My Z4 3.0 SE (2003) has developed an annoying rattling sound, I thought it migh have been due to a broken mounting on the undertray so I've taken that off but the rattling persists!

It's not that loud just a "chattering" sound while going over bumps, uneven roads etc, on smooth roads there's no noise, handling doesn't seem affected.

Just wondered if anybody here had similar?

Cheers

It's pretty hard to pinpoint actually which is annoying in itself

Sometimes it sound like it's coming from the rear of the car, I think broken rear spring are a common fault so I wondered if this struck a cord with somebody.

I have a Warranty Direct warranty on the car, looks like I will have to book it in for a check.

Had it up on a four post lift, everything was given a good wiggle and springs are fine but the annoying rattle persists, it sounds like it could be coming from under the dashboard somewhere.

I've wanted to give my local BMW Independant a try so I've booked it into:-

St Ives (Cambridgeshire) to let them have a look.

OK so I found out what it was, the weld on this bar had failed:-

I'm having it re-welded this arvo.

Can't be bothered to mess about, just getting it welded.

Not on that end, it's bolted to a flange, the flange has come away from the rest of the car.
