Hi all. Had this annoying noise since I've had the car (3months...). It is engine related, gets faster with engine speed - taps once a second at idle. It seems to be coming from the vac pump on the front, does that sound plausible? Is the tapping a worn part, can the pump be replaced...

Hey everyone, I purchased a 1997 328i about two months ago and the engine has had no issues until this morning when I heard a concerning tapping noise coming from the engine. It seems to happen when idling and warm. Here is a video...

Hi all, I noticed today my car suddenly, out of the blue, started making a loud tapping mechanical sound. Upon closer inspection I saw that the Aircon belt had fallen off and was lying on the undertray. I looked at some diagrams of the E46 belts and noticed they all seemed to have tensioners...

Has anyone else experienced a whining noise when tapping the accelerator. I have a 430d on a 64 plate. The dealer replaced the air box and now says the noise is normal for that car but it sounds like two marbles rubbing against each other. It starts when the engine is hot and you can hear it...

Hey guys, Bought my 325i a month ago, drove and felt absolutely perfect. Only done 3 long journeys, the last one being a couple of weeks back - it's at 78K miles and hasn't had any previous issues regarding sounds or performance. About a week ago, I noticed an odd tapping sound when I was...

Firstly let me introduce myself. I am new to this forum but not new to BMW by any stretch, I am a hard headed BMW fan and my last 3 cars have consisted of an E92 Coupe 335d M Sport which I had mapped, an E92 M3 Coupe in manual (manual being the big mistake there) and onto my current E92 335i M...

I have recently brought this car. Can anyone help. I have a intermittent tapping noise coming from around the bottom end (I think). It only happens when first started. When driven and engine becomes warm the noise goes away. Any help would be appreciated. Recently had the crank pulley replaced...

My E61 530D has developed a tapping noise from the top end of the engine, and I am trying to work out what is causing it. It taps at half engine speed, so camshaft speed, it sounds similar to a slack tappet. I have heard that various things might be the cause, including a worn tappet, faulty...

Video is taken in night sorry for that. I recently got some knocking that is most noticeable when i stand next to rear wheel. In the engine area the noise is not that loud maybe lost in the engine noise. It seems that it comes from under the car or behind the front wheel. Knocking gets...

I previously thought I had fixed this issue but it's still there, regardless engine is hot or cold. It's intermittent, doesn't matter what type of diesel is used. All Injectors have been reconditioned, they've been done by two seperate specialists but the noise is still there. Does anyone...

Having never owned a diesel other than work van I'm not sure if this is normal? I removed the oil filler cap today with the engine running to top the oil up, it made a loud tapping noise??? When the cap is on it's silent? Is this normal??

My 530D has 151K on the clock, my indy replaced the cam cover gasket recently, which involves removing the injectors -one was quite tight, and they struggled to remove it. When I collected the car they did say that a new injector might be required - it turns out this same injector was out of...

Hi all, Been a member for a while but this is my first post. Had the car a while, it always made a feint metallic tapping noise at the from of the engine. It since got louder and more noticeable higher up the Rev range. One injector was out so had them all reconditioned. Engine much...

Hi guys, I've been searching myself silly for the last couple of hours to no avail and finally decided to post in case someone has some idea about my problem. Issue: Simply; I'm want to get access to some of the speaker wires near the boot (i.e. the parcel shelf speakers). Reason: Stock...
