MY BMW IS DEAD // DME & CAS REMOVAL

Today on JD Cars we will be removing the DME and CAS module on my 2007 BMW 328i.
The Full Story: I was testing voltages on the hazard light button connector as instructed by a company (they shall remain unnamed) who asked me to do an interior light installation. Something must’ve have went wrong because the car went haywire. The windshield wipers went nuts- couldn’t stop them other than pulling the fuse, my whole dash died, no A/C, no turn signals, rear windows died, no headlight controls, the car is in limp mode, and it takes about 6 seconds of cranking before it fires and runs. I’ve checked numerous fuses and haven’t found a single blown one, and to top it off... the OBD port is not communicating whatsoever! I’d appreciate all and any help from you guys.
I have sent these components into a European automotive computer company who will hopefully be able to resolve the problem.
Still more BMW videos to come, as well as other exciting surprise videos! Thanks for watching. Please like and subscribe!

Thank you for actually showing the details of how to remove each part, most other videos skip ahead or fast forward through some very annoying parts, I just wish I had seen your video before I removed my DME, I didn’t disconnect my battery, hope I didn’t fry some components in my car…

[@Thatguynicoo]

This is by far the most informative video for BMW CAS location/removal. Removing the CAS is really, really, reallyyyyyy annoying.

[@JDCarsChannel]

Thanks man! Yeah, it really is a pain.

[@CGTSX07]

Reinstalling is literally twice as bad

[@nickf1724]

i hope you get the e90 back up and running, youve put so much hard work into making it exactly how you want it

[@JDCarsChannel]

Thank you!

Thanks, I would of never got the wiring harness without following your instructions.

Always swap out your (IVM)) on any used BMW. Always start with the IVM first. It distributes power to all major components on your Engine, including the Starter. It has several internal relays built into the IVM. The IVM is not that expensive.

Where is it located

[@davidhall3747]

@@mtbridingog9083 It should be located adjacent to all your other ECM's. Next to your DME's. I drive a Seven Series BMW 760i. Not too familiar with 5 & 3 series BMW's.

[@frankponcherello8128]

Bro.... same thing happened to my e90 and the cause of it was due to constantly programming my car using the BMW Carly app. I ended up fixing my car by replacing the module. I purchased a used one from a junk yard for $150 and it fixed the problem. I hope you get your car fixed soon. Good luck!

[@JDCarsChannel]

Thank you!

Gone but not forgotten 🤧

[@Babycute82]

My E60 had a similar issue. I took it to the dealer and they couldn’t figure it out either so I had to sell the car. The saddest day of my life.😢 I really hope you’re able to get you car back up and running because you have an awesome car.👌🏽

[@JDCarsChannel]

Uh oh... I hope I can get mine back up and running.

[@charlesc306]

Sorry to hear bro, thats rough. If this doesn't work out, it might be a hike for you and they're kind of expensive, but motorcepts inc. in Queens, NY might be able to help. They specialize in BMWs and have seen almost anything. Give em a call and see if they might be able to help you. Good luck.

[@JDCarsChannel]

Thank you! I have good news coming this Friday!

[@bird718]

have you tried pulling all the bulbs out and replaced them with the OEM lights? let it run for like 10 mins to adjust voltage and check again?

[@funitoo]

My E90 had the ECU die recently. It was due to water ingress, the inside has been slowly corroding until eventually it gave up the ghost. It wasn't obvious from the outside and only when I opened it that I saw the corrosion. After some investigating I discovered that there is very poor drainage in the ECU box well. Water drains very slowly and if there is a rain storm (or maybe carwash) the water will not drain fast enough and the ECU box will flood from underneath. Judging from the water mark on the inside of the ECU there was an inch of water in there probably many times (ECU is not watertight). My car is a RHD so it might not be the same for you but I would remove the ECU box and check it anyway. I drilled a big hole in there to allow drainage. I also sealed the bottom half of the ECU with silicone. But you need to make sure it's non acidic sealant or you might do more damage than good. BTW DDE is an ECU for the diesel cars so Europe only I guess.

[@JDCarsChannel]

Sorry to hear that happened to you. I hope to figure out the issue soon!

[@sionsdad]

Thank you for the video. I am swapping out a 318d and fitting a 320d both 2008. I assume I will need to swap out the DME from the 320d and tranplant across with the engine to the 318d body. I then assume I will need either the DME reprogramming to match the cas and BCM. Does anybody know who can reprogram the DME? North Wales UK.

[@Christopher9835]

I had the exact same problem last winter replace the frm module

[@faraztung3846]

Were you able to fix it?

[@nathanieljames8689]

Hey just wanted to know the company you used to program your CAS...

What codes did you get for this fault. Was it the DME at fault

[@christbell2]

Check the frm module!! It controls your lights and everything!!

[@GiovanniSerratoSG]

Chris B I suggested this as well in the picture he posted. Hopefully it may be the ECU or cas. But definitely will be frm module if nothing else works

[@JDCarsChannel]

I think the FRM very well could be the culprit.

any update? my car has the same issue

[@rlmartinez15]

JD great video, I have an issue with my 2007 BMW as well, won’t crank, after spending weeks trying to figure it out I finally talk it to the dealer, they told me it was the CAS and had no communication with the ODB. Curious to where you sent your to be repaired, Thanks

[@JDCarsChannel]

I sent mine to the dealer to be repaired... they couldn't figure it out. I took it home and finally figured out that it was the junction box module.

[@crazyharis]

@@JDCarsChannel hi my English is not that good what do you Mean the junction module ?

[@schafer240]

It's the box on top of the battery, fuses in there, that are not replaceable. Have to get a complete new junction box

[@RayRx84]

Hi, I’m having some electrical issues bc I think it maybe my DME or CAS module. I was wondering what company did you send to and how much was it to check is it’s still working properly? If it is the problem do you need to recode them if getting new ones? Also did you have any error codes? I know you fixed the problem and it’s the JBE Box. Thanks!

[@JDCarsChannel]

I’m sorry I forget where exactly I sent my DME - I think it was DME doctor or something like that. I was unable to check for error codes because the OBD port wasn’t working.

[@solomonnaman1721]

What's the name of the company you sent the units to?

[@swervin-482]

Hey JD, ever find out what it was? im having the same issue, cranks and cranks but no start on my 325i. checked mostly everything what it could be and this might be what my car is going through. thanks

Wow... I'm sorry you are going through this with your car! I hope you can get it all together and find the issue... Mine gave me the steering wheel lock sign yesterday and it did not wanted to turn on at all... I had to tow my car home and today I'll try to fix it and see whats wrong with it. By the way, have you think about getting the CARLY FOR BMW?

[@JDCarsChannel]

Uh oh... I hope your car is alright. I have CARLY for BMW, but it was unable to communicate with the car.

[@christiancorrea8426]

JD Cars wow... Sorry once again, i hope you get it to work and keep updating to see what was the issue. I got my car to run again once i hit the steering wheel like 20 times, then the wheel got to unlock. But i need to find out how to get it fixed 100%, I guess I need a Carly.

[@keitho77]

Would the CAS module control the gearshift position LED and backlight for the Start/Stop button? I have a battery drain issue on the 2008 320D that I am trying to troubleshoot. These lights are remaining active after the car is powered off and locked using the central locking. Even after 30mins these lights are remaining on. Removing the PDC module stopped the battery drain and I have read that the relay on the junction box for the PDC is controlled by the CAS module (Terminal 15 KL15).

[@JDCarsChannel]

That's strange... those lights shouldn't be on that long after locking the car. Sounds like a coding/module issue.

[@keitho77]

@@JDCarsChannel Do you know f those lights are controlled by the CAS module or even the CAS2 module?

[@pedecia]

Hi JD Cars, needs some help please as I am desperate with my 2012 F30 328i. I disconnected the battery when I went overseas. Came back and connected the battery back and not all is dead. The only things that work are the electric seats, comes the BMW logo on the dashboard and the positioning lights. All the rest is all dead. The car is in my garage unable to start, the BMW dealer wants me to tow the car in and wants 300AUD/hr plus 200AUD for the tow. I would be happy to pay if there was a security to have the car fixed but I am worry the tech would not be able to connect to the car onboard computer to access the faults like in your case.... What would you recommend? The battery is fully charged as I used a CTEK charger... I was thinking in buying an icarsoft CR Pro to check if I could connect to the car CPU... Any advice is welcomed!!

I have a 2002 BMW 745li we had a flat going about 70 did some damage to the front end and wires were hanging down from under the right front the tire ripped off the under cover and a lot of wires were bare and touching... after getting the car home and doing the repairs fixing the wires and all... I tried to start it and it almost started and then died... now the key fob wont accept the key and dash lights are flashing... and heavy battery drain... im not sure if it damaged the ECU but after seeing all its doing I'm going to order a new one and have it programed to the car... my question is could this effect or damage the CAS...? my wonderful bmw mechanic says... the CAS is damaged... and all the computors and modules are fried... but he couldn't connect the car to his computer because there is no communication from the ecu for him to check anything... he quoted me $4-6000 to repair... I will take it step by step and see if what he is saying is true... but I will start with the ecu and go from there

[@JDCarsChannel]

He probably gave you such a high quote due to the diagnosis process. Resolving the issue will require replacing modules one by one to figure out which one is fried. You could try buying them used off eBay like I did. I saved myself hundreds of dollars.

Hi ya had same problem with my car fault codes DME . CRANK NO START . changed ecu was not that. Changed ecu crank shaft sensor key and module still same problem. In the end changed fuse box. Started on the button. Changed everything back good as gold. When I stripped fuse box at the back looked like there had been water in it at some point this my help someone out have no problems with car now. Hope this helps

[@Derekl369]

Check the junction box in the car behind the glove box my car did the exact same thing and that was the problem

[@JDCarsChannel]

What fuse? Or was the entire junction box fried?

[@Derekl369]

It’s a black box that sits under the fuse box

[@Derekl369]

The junction box was fried on mine

[@Benzsingha]

Also happened on mine. Luckily I had an extra from a totaled E90 I had sitting on my lot, replaced it and now back to normal with no problems.

[@benassy69]

Really sad to hear about your problem :( Do you suspect that the LED bulbs that you just installed are the culprit for this problem?

[@JDCarsChannel]

I think it was the voltage testing that caused the problem :(

[@cezsantos2161]

So it’s not the new bulbs because I want them?

Called bmw and returned it to them, turns out they forgot to plug the alternator back to the battery after the oil change. It took them 5 days to finally plug it in and I was without it for a week it was the worst thing being without my e90 felt like I took her for granted sometimes 😂

Hey JD, I had a 2004 BMW 530i. First year e60, in 3.5 years I dumped $25,000 in maintenance and repairs into it. Any BMW from 2004-2007 are by far the worse and most unreliable designs, my friend also had an 08 328xi e90, driveshaft bolts came loose, and hit the freeway then smacked the oil pan and busted it, and damaged his bumper. The BMWs of this generation (mine destroyed its transmission) e60-e90 are terrible, and should be avoided. Gorgeous cars but you’re better off with an F30 or an e39, or even an e46. Trust me dude, this is just the beginning... I sold mine. And was looking at an F30, but have been gravitating towards Mercedes-Benz, and although they are more reliable. They are not DIY Friendly and labor and parts are higher. But less likely to constantly break down, and because well the e350 4Matic AMG Sport is sick. Insurance is expensive though, hit me up on snap my friend (joeymcmahonuhhh) I’ll help you with your BMW whenever. Like I said, this is just the beginning.

[@iAlwaysSpeakTheTruth]

Update I just bought an F30 lol

[@MyNeowolf]

25k in repairs? need to diy and research cheaper ways to get parts. stealerships and even some inde shops will let you spend as much as your willing. we didnt spend a quarter of that maintaining m5 including rod bearings,smg clutch pump, folding mirrors repair,vanos pump

[@thefirstBmazing]

Hey any follow up? Did the company you sent it to fix it? Asking because I have the same issue :( Also at the end of the video you said a new DME is $600? Isn’t it more like $1300 without programming? :/

Watch the video following this one for the update. They didn’t fix it. A new DME is cheaper used on eBay.. probably pretty expensive from BMW
