Transmission Vibration

Hi

My 2002 X5 has a vibration & associated noise when you apply light load to the engine in 4th or 5th between 1500 - 2500rpm.

If you continue to accelerate the box kicks down and the vibration clears instantly only to reappear when it changes up and gets to the above rev range.

Has anyone else come across this problem and if so what can be done?

Thanks

TBP

Thinking through logically Drive and Propshaft speed will increase with road speed as will the gearbox internals so are you sure its gearbox?

The issue seems to be engine speed related so could it be water pump? alternator? or aircon compressor? or engine driven fan. These items will be affected by engine speed not road speed. They are also the simpler/cheaper to fix items.

The only other thing it could be is Torque converter that is engine speed driven but that is a box out fix so ££££'s I hope its the simpler things.

Just my thoughts

      Amplifier replacement.

      Thank you Dave for the welcome and the reply. The original unit, i believe, was the next stereo up from the base unit, not anything flasher than that. BMW are about as much use as a chocolate teapot and can't/won't tell me what i need without me booking it in with them for them to look and diagnose any issues. My nearest BMW dealer is 30+ miles away and i really don't have the time or enthusiasm to make the trip for them to sell me all the OEM equipment that was removed last time the same fault happened. The issue is the well documented (and ignored by BMW) problem of water entering the boot and sills due to a design flaw, short of silicone sealing all the rear light fittings and drilling holes into my boot floor to drain the water, the issue will continue. Once i figure out what Amp i can replace this one with, i will be looking at jacking up the Amp or creating a unit to sit it in to keep it out of any standing water. Thanks again Dave.

      Amplifier replacement.

      Hi Danny Welcome to the Forum I thought the Amp would be Harmen Becker or Harman Kardon may be Bowers & Wilkins (High end stuff) if it was OEM ? The concern I would have is why the fuses were really, well fused to do that to 40 amp fuses isn't good news. I would have an Audio Specialist look at it if you can't sort it yourself. Take a look at www.realoem.com put the last 7 digits of your Vin into the search box it will bring up your model the check the Audio section to see what should be there. Then look at what to fix or change Dave

      Amplifier replacement.

      Hi All I have a BMW 428i F33 2014 model. The audio amplifiers has been replaced. I bought the car second hand, after less than 3 days the audio amplifier popped and it was replaced by the garage i bought the car from (at no cost to me). However it has blown again. All sounds, both audio system and the normal bings and bongs have all stopped. I have taken the unit out of the boot and discovered it has been replaced with an Audison Bit Ten Signal Interface Processor bit drive and a Hertz Mille ML Power 5 5 Channel Amplifier. It is clearly the Hertz unit that has fried. Both 40amp fuses are welded in place and the unit stinks of burnt electronics. The Audison unit still gets power and appears fine. My question is, do i need to replace the Hertz unit with the same unit again? They are just over £600 for a new one, or can i use any 5 channel 900w amplifier? ( i know next to nothing about car stereos) Has anyone else had the same or similar issue? I don't want a mega pounding, super maxed out stereo, i just want the car to bing and bong again and be able to listen to Radio X on my 7 minute drive to work! I may possibly have included some pictures below? Thanks for your expertise and guidance 1000012573.heic 1000012574.heic 1000012575.heic 1000012576.heic

      230e Active Tourer Control Display

      Hi, just got a new 230e Active Tourer and joined the forum. Love the car, especially when running on electric motors only, but it has an issue with the curved panel control display that doesn’t always switch on when I start up but then randomly starts up 10 mins later. BMW dealer hasn’t seen it before so it’s booked in for an inspection next week. Has anyone else seen this on on any of the new plug in hybrids with the same display panel?
