BMW 6-Series Hidden Water Drain - The E-BOX one! 

This is great help for alot of BMW owners. A good sign moisture has entered the Ebox is the Ebox fan will set a fault code showing a short to ground or open. The high end BMW's pump cold air from the AC into the box. Another source of condensation. I went thru 2 ebox fans before I figured this one out. I live in a humid climate and some of the AC condensation ends up in the Ebox. On my E70, I had to drill a very small hole in the very bottom of the ebox close to the ebox fan. If you see a rusty bottom in the ebox, this may be the source.

Hi Timm my name is Alvin. I just got the 2005 645ci with 34,000 miles. This is a great machine. You will be my go to BMW tech. Your videos are very simple to follow. I also subscribed to your channel. God bless you and your family.

Hi Timm, I had water around the e box. Not caused any problem, but does worry me. I have taken a spray head off of a windowlene bottle and extended the tubing. I used it as a pump to pull the water out. Wish I knew how to unblock the drain. I had the e box open a couple of years ago to do valve cover gaskets. I’m sure some wires come up through the bottom and into the IVM module. If the ebox sits in water too long, it’s bound to get in. Great video by the way👍

Tim, as always, GREAT video. Thank you for all the time you take to put these videos together so that all of us that have a 650i can benefit from your knowledge. I have never cleaned my drains but the car is always garaged. I will clean them after all the leaves come off the trees this month. Many thanks again, Tim.

I love all your videos and they help me work on my car. I own a 2010 650i e63 and there are not that many good videos on youtube that explain or show how specific things are done. Thank you and keep up the good work 👍🏻

Thanks again Timm for another very informative vid. I'll check water drainage before stripping wheel lining. 2 great cars you got👍👌

Greetings Timm, love your beautifully narrated and informative videos.I purchased my first BMW several days ago, an E63 BMW645ci, 2004. Prior to this I had taken many other cars for test drives, but liked the handling, luxury and power of this vehicle. Having some basic car knowledge (gleaned mainly through Japanese car ownership) I thought I'd be able to run basic maintenance and repairs myself. However the saying that German vehicles are over engineered certainly became apparent within the short time I've owned this car.Your humorous, yet no nonsense DIY tutorials have helped explain a lot of the strange and new systems I am encountering.A huge thank you for the effort you have put into making these and the assistance you have provided not only me but many other BMW owners.

A really useful video, I wish you'd been posting a few years ago when I first got my E63. It would have helped me diagnose the flooding of the cabin which was due to a blocked drain under the brakebooster. Keep posting. :o)

Thank you for making this video. That eBox is also on the passenger side for the US version and is a b!tch to move. I will be cleaning my drains as well.

Great video my friend. Another thing you've helped me with on my 650

I'm going to be having a look at this shortly. a few months ago i took out 9 litres of water out of my rear drivers footwell, yes NINE, (glad I'm parked on a slight incline) removed all seats and the rear part of the carpet and let it dry, took ages, the drivers side turned out to be the drain under the brake booster,. drivers side nice and dry now even with the lots of rain we have had, but the passengers side is a tad soggy :(, so out the passenger side seat out again , its either that or a failed door membrane , more investigation required, but now i know where the passenger drain hole is

Hello Timm, wanted to take the time to show some apreciation for the videos you've been doing. They've proven to be very useful and helping me with learning to take proper care of my e63. Hence why I also had an idea for another video. I was wondering if you could do a comprehensive owners guide for all recommended maintenance tips, such as when you change your oils and all the good details like what's shown on this video. I'm sure it would be super helpful for all the upcoming and present owners of these beautiful machines. Wishing you a great 2021. Greetings from Finland.

superbe vidéo comme d habitude

Brilliant, just what I wanted to see and understand.. I had cleaned out the brake servo side on my E63, and yes it had about 2” of water in it, enough for a 🐠 what a silly design! I just pulled the rubber bung and have left it out now. The wing ‘leaf catcher’ was full of mulch, so I blasted it with the hose. It was the E box side that had me a bit stumped..until now, so thanks for the video, much appreciated 👍🏼

I like the wood stop piece to stop for ramp. Great idea

Hi Tim, another helpful video, I had a shock when my e63 driver side footwell and the passenger footwell was absolutely drenched to my horror, always kept my car parked on a downward slope just in case there was a blockage etc just to minimise any risk of water coming in if there was a blockage somewhere, just this one time on holiday in October last year where the car was parked on a slight incline nose up and after a through wash with a outside hose, a luxury I don't have at home. I have always kept the 2 side scuttle valves clear of leaves and crap but traced back the blockage to under the brake servo, where the area under the servo the paint had been eaten away and blocked the small drain, no doubt from where progressive dealerships had not been careful enough when filling the reservoir and the brake fluid has dripped/spilled causing the problem, am really angry and upset as I keep my car as in good a condition as I can, I spoke to my current bmw dealer BMW park lane who have just gone silent after deciding to tell them as they were the last people to do the brake fluid change in fact the car has never been outside the network and they should take ownership of the problem only because it took 2 months for me to get the last of the water out in this cold weather and because of the potential damage to the subwoofer/amplifier under my seat. Just something else you may find helpful. The service advisor claimed that they don't fill the fluid fro up there but at the bleed nipples by the wheels which sounds like crap imho.

Thanks for taking one for the team

Thanks Tim, your videos are really helpful Can I ask how do you keep your wheels so clean of brake dust? I’ve tried all the usual stuff but mine always end up with ingrained black between the spokes that I can’t remove

Hi Tim, vacuum what you can and then use the hose. I have a chainsaw you can have a lend of if want?😁👍

Hi Tim..I've noticed on my 2010 E64 635D LCI that rain water is not finding an egress point. Drivers side..where the roof closes and meets the corner rubber cup housing situated up in rh side of the bodywork around the.front window screen. So water is dripping in over the window control point on the driver door. Any suggestion for where a secret drainage point is or which drainage point may be blocked... Cheers

Did u ceramic coat your cars paint looks new on the e64 and e31 or just wax?

hi tim i have a problem with my pdc e63 2005 both front and back not working? do you do repairs?

Tim I also have an e64, 08. 650 my infotainment system completely failed on me, it does turn on and show a screen, however moving the knob does nothing and there is no sound coming from the car at all, checked amplifier and replaced it and still no luck, any tips on what I can check or do? Thank you

Hi Tim I have a 2014 650i where is the a/c drain please respond thanks

My 630i on approach to a roundabout or junction gets almost stuck when I put my foot on the Excelerate pedal..so I m doing normal 20 or 30 slowing down then as I have to pull out etc it's almost like power gone then it kicks in and carrys on being normal.. Help please only bought it last week after watching your videos amongst others..

Where did u get your wheels and are they 19” or 20”

I have the E60 same era and found over last few days puddles in front driver well and rear drivers side footwell. Wondering if I have leak from front below bonnet ie brake fluid bin area and water flowing to back seat area. Or I have 2 leaks from rear door and front under bonnet area? Been tipping water out and it’s not ideal and windows are all steamed up. Need help.. not sure what to do.

I think I'd use a razor and slice off the flap door. Seems it would solve alot of issues.

Hi Tim

I'll give you the bad news.water can get into the e box from the bottom.ive just lost 2 ecus in 8 months due to blocked gully.im just about to pull those rubber grommets to prevent it happening again

Mate I love you accents

You're in England where if it's not raining, it's bloody cold. So why do you have a convertible top car??? Trade that cherry tree for a conifer. You can borrow an axe from our George Washington.

Hi Tim. As a new owner I’m Loving my E64 but I’ve had a leak in the boot but doesn’t look to come from blocked drains. There are three air vent round holes above the amplifier and has water marks coming from there. Any idea how water comes from there?
