Dealer BUTCHERED this BMW?! (Crank No-Start)

[@wammyz]

Did the dealer actually do the work? The owner did change the pump and module, and as someone already mentioned, how did it get home? Just a thought, maybe he changed the gasket himself and didn't hooked the ground back up. Just a thought, I know dealers screw up plenty but sometimes it's hard for owners to admit they screwed up.

[@additudeobx]

Yeah, that's exactly right. I'd bet that if the "dealer mechanic" was doing that job, that mechanic is certified and knows, "Death Do Us Part" if those grounds are not hooked up...

[@baxrok2.]

Good point, I think you may be right. Maybe that's why Ivan never heard back from the owner. When Ivan makes a return visit to program the new ECU that the owner puts in we'll know the truth!

[@Tengs27]

Agree, he was probably, " let me start the thing before hooking everything up ". Mistakes happens to everyone and this is probably "learning the hard way" for him.

[@noelcastle3986]

[@neilmurphy845]

I think you might be right That makes sense because if something like a fuel pump got damaged you couldn't drive a car home like that

[@nv1493]

Yeah I'm suspicious .... this seems kind of fishy. Dealer works on car, car doesn't run. How'd it get to his house? Sound evidence of wiring left disconnected, anybody would be calling the dealer to pick it up. Owner says nah, I'll just pay for new ECU and programming. Never gets back to our man about resolution. Methinks there's more to this one...

[@NewLevelAuto]

I see a LOT of comments about how the vehicle made it home. My best guess judging by the video is that the ground cable may have still been touching ground for a bit after the work was done at the dealer. The loss of ground during the drive may not be immediately evident outside of a frostbite misfire because of the current finding a path to ground through another ground path ( not a good one). Certainly there is potential in a case like this that the customer could have been making something up, bit I think I remember there being an invoice mentioned on that phone call.

[@jayp1013]

Sounds like there is more to the story because if the valve cover wasn’t touched other than by the dealer then it’s clearly their fault and they should pay for it .

[@exmotorsports]

Kinda what I was wondering at first too..just how much of driving around until it finally gave up. Electricity does have it's funny and sometimes destructive way to find ground.

Did you address the A0B4 code being thrown by the CAS? If you crank the car enough times without starting, the CAS will disable the car. It's an anti-theft feature. You have to use INPA or other BMW tools to resynch the CAS and the DME. That might be causing your problem.

[@youutartur1104]

There is a chance the DME could be fried but those grounds are for shunt dissipation, the coils are designed to multistrike and what I mean is that after the initial ramp and closing of the field they will still strike 5-7 more times, and whatever build up of electricity is left shunts through those grounds. Effectively, the coils do still spark even if you took all 3 grounds off or in the case of the Mini Prince motors you leave its single ground off. BMW products have never killed spark for any reason in a cylinder even a dead hole misfire. I would not forget to try starting it with the Valvetronic eccentric shaft sensor unplugged, or even unplugging the motor and turning the eccentric shaft by hand by means of sticking a 5mm allen in the motor and leaving it in a different position, Valvetronic will failsafe and you will use the throttle body as your means of intaking air. I have seen the eccentric shaft sensors do crazy things, and because its mounted to the actual cylinder head inside the valve cover and its female connector sticks out through it there is a chance of damaging it when removing the cover. Also, an uncoded EKP will just throw the fuel pump into full working load. The weird cranking could be the valvetronic not knowing what is going on and hitting a different setpoint as it opens and closes the intake valves as it tries to start. On another note too, that car is 12 years old, the coils are so notorious for failing we do a nice and dandy easy 36 a week. Not saying throw parts at it, but make sure the coils are in working order. Some of the things I've mentioned might be common knowledge, don't know, but all I do is BMW/Mini products so sorry if it's something you already know. The only BMW product I know that really does not like those shunt protectors not installed is the V8 twin turbo with the ground being integrated into the plastic shrouding over the coils, very very easy thing to forget and very costly when it kills the TWO DMEs, and kills the BSD signal meaning alternator, oil level sensor, IBS in the trunk, water pump... and if you don't replace all you run the risk of frying all those AGAIN after startup, with the ground reinstalled. There is a TSB for that one.

[@fuckjewtube69]

Good info. What does it mean when the steering wheel shudders when at a stop and turning lock to lock? I can't figure that out.

[@TheFrenchPug]

I was also thinking valvetronic issue. I haven't done a non turbo 3 series but have read they can cause these issues when not reinstalled and endpoints re-adapted properly.

[@peto22]

Not true! This type of coil is actually a transformer and high voltage side is connected to ground and to the spark plug. It wont spark (at the spark plug) if the ground is off. It will cook the ignition coil and then the spark enters the low voltage side and the engine control unit. I have diagram of those coils -> mankeli.dy.fi/bmw/328coil.jpg

They did set the key coding and such correctly so I was like fiiiiiine leave it and took the car over to a local tuner and said hey here you go keys for the car. Do your magic make the car run as good as you can. Ended up with a much better firmware update that got the car near 300hp and 2stage limiter. Ripped out the boost controller all together and hardwired the boost to stay at maximum and compensate with fuel and timing.

That will be their argument.

[@PineHollowAutoDiagnostics]

It drove OK for a couple days, but kept getting worse. Luckily made it back to the garage before completely crapping out.

[@TheFrenchPug]

@@PineHollowAutoDiagnostics That makes better sense. That ground vibrated loose then. When I forgot my ground (to put it back on bank 1) the car just ran horribly. Then I saw it. Put it on and vrooooom. No fried ecu. But they can be easy to miss.

[@ianriggs]

thing sounds like it has weird compression while cranking

[@danielclark5170]

I would get that BMW fixed and sell that piece of junk.

The ignition coils for this car is a 3 wire type, but this doesn't mean the transistor is integrated in the coil itself !! ON THIS CAR THE CONTROL TRANSISTOR IS IN THE ECM!. The pins for the coils are - 1st is Fused power , 2nd is switched ground from the transistor IN THE ECM !!! . 3rd pin is additional ground for the secondary coil. And my theory is . When this additional ground (3rd pin) was left unbolted , still the car could be driven out from the dealer garage , but the coils slowly started to heat. This ruined the coils . But more importantly , melted the coil winding insulation. Which caused the winding to touch each other and short out. This led to high current travelling through the shorted coil to the control TRANSISTOR IN ECM.

Now the first time I heard the engine crank it sounded like one cylinder had less pressure than the rest. So let's see what is found.

[@TheFrenchPug]

They sound bad with the engine cover off so when they're actually bad, they sound horrendous!

[@jackiemay9471]

yes i thought i heard a fault in the caydence when cranking

[@CXensation]

1) How on earth can an otherwise renown car maker design an engine computer, that immediately burns out when a ground connection is missing ? 2) How on earth can a dealer known for their white suits and gloves do such a mistake ? ...

[@TheFrenchPug]

Owning and working on a few different BMWs makes me think it something else because he drove it home. A new ECU just seems least likely. It's always something stupid simple unless it's mechanical. But, Ivan is eons better than me in diagnosing these things.

[@mikefoehr235]

Why on gods earth do people buy German cars in the first place. Theybare all utter expensive garbage 🗑 for the most part. I am of German ancestry BUT I love Toyota. For me anyway....most reliable there is.

[@ryans413]

@@TheFrenchPug ground probably regulates the power it probably worked all the way home and then it got fried and wouldn’t work anymore

[@TheFrenchPug]

@@ryans413 That seems to be the most logical explanation. Poor guy. Ths really sucks for him.

[@DDescalchuk57]

New fords can’t have their coil connector unplugged while running. It’ll also fry the tbe pcm. They need a path to ground

[@TheFrenchPug]

Maybe there is something to this then.

[@advancedleveldiagnostics]

Doesn't it look like the intake valve is opening late, that's why there is a vacuum pocket when it opens?

[@TheFrenchPug]

A bad reinstall on the valvetronic motor in the valve cover which can cause this problem also.

[@ablackformula]

I was wondering the same thing! Also looks like a loss of compression, the expansion stroke ends at a way lower pressure than the compression stroke started at. Granted this can simply be cylinder wash. I also don't understand the fuel injector timing. It's on the expansion stroke, after the spark plug should've already ignited the mixture. All channels were for the same cylinder, correct?

[@advancedleveldiagnostics]

@@ablackformula I agree I usually see the injector on the intake stroke.

Epic diag hands down, Really humble of u to call in for help.

[@craigjasper2502]

The Owner looked suoer happy as most BMW owners lol.

[@TonyRule]

Nice to know these turds are so well engineered that something as simple to fix as a broken ground will have far reaching expensive ramifications.

[@baxrok2.]

Unreal. Can't even imagine the laziness and sloppy brainless work on a simple valve cover swap. Thanks Ivan!

[@nickmalone3143]

More troubling is the fact that one tiny wire can bring the whole car down and/or destroy the ECU ...thats crazy engineering...weakest link theory

[@baxrok2.]

@@nickmalone3143 Completely agree!

[@kurtkennedy5370]

As a former BMW / MINI Tech at the dealer, there is a 100% chance this was left loose at the dealership. This is as common knowledge as where the bathroom is located. Views getting low lately? Seems like you're bashing of dealer techs is getting a bit outlandish recently.

[@speedy_pit_stop]

Guy brings his car to dealership to have valve cover gaskets done under warranty, then proceeds to replace fuel pump and orders new control module... sure.. yeah.. that makes sense.. Anyone can make a mistake though, and the fact that Ivan had to call Keith for rescue says a lot and will be a learning experience to many.

[@uzi1951]

How did he drive it home??

[@joehomanick]

Great video as always Ivan !!!!! That battery sounded shot . It was cranking soooooo slow

[@markferraro5250]

Great info thanks IVAN

[@cheapers1952]

I bet the owner can't afford BMW prices neither but he sure as hell wants to drive that BMW

[@tamiibrock6176]

I have 2014 Hyundai Sonata 2.0 4th gear ⚙️ makes hard shift and rpm go all the way to 6000. I changed fluid 3 times. Nothing changed.

[@htownblue11]

That’s an internal,solenoid issue or clutch related issue inside the transmission most likely.

[@kevinmccreary3123]

You could tell no spark tach should no RPM

[@baronbarbaron]

I wander when german car makers start to code the fuses and the light bulbs... I'll never buy a german car again, I had WV passat full of problems, the mechanics sayd "this is a common problem in this model" for everything which failed and I started to wonder is something in it whitch isn't a common problem. I got friends with BMW and it was the only car which I pushed down to the hill and still can't move on it's own power. Germans love to overcomplicate the cars to pump the price and do the maintenance expensive. This cars are botomless pit to throw a money in.... Damn, why even such a module exist the pump is just a DC motor...

[@mr_mnky]

There's a toolbox in the background. I kow a wrenchmonkey's garage when I see one. The guy obviously did the work himself, or had someone come over & do it for him, and he simply wanted to save face by blaming the dealership. Either way, he just screwed himself out of a bunch of money.

[@joseguerrero8078]

Exactly how the car get from dealer to there?

[@PineHollowAutoDiagnostics]

It drove.

[@n9wox]

Can the DME be sent out for repair by a bench tech?

[@martinamadsen812]

This video just confirm my view that modern car's are tricked up too much and as a result there are too many areas where problems can occour and the vehicles are both difficult to repair and expensive to keep going.$$$ 🤔 Regards Niels.

Aren't you lucky living in USA when you can film/photograph whilst driving. Here in the UK you'd likely lose your licence.

[@DM-hw4cr]

A used car dealer? It's not in a BMW dealers interest to butcher expensive cars that they work on EVERY DAY. I smell BS.

[@MichaelATH]

That battery sounds like it’s had it, the crank is so slow. Trying to diagnose a car with without proper power isn’t a good idea. More to the point How did the car get home in that state? They came off when it was pulled into the garage? Hmmmmm………I smell BS
