Bmw dealership blunder? Incompetence?

Majority of dealerships are now staffed with replacement technicians, not analysts.

Another really interesting one. I didn't realise the HPFP had that kind of electronic control valve on it, but makes complete sense. When the other garage says they checked the timing, I think they mean they checked the workshop clock and decided it was time to go home 😂

Dan is a master at his craft. Next level. Changing parts is a skill in itself, but truly diagnosing these vehicles is a “WNL” WHOLE ‘NOTHER LEVEL”. Dan is a blessing to his customers for sure.

In 30 years there's going to be no classic cars from this era. The manufacturers have made them too complicated for the average mechanic to fix economically. Most of the complexity has little or no function except to ensure the car ends up back at the dealer more often then it normally would need to.

If dealerships start recommending parts that aren't the issue. The parts should be free. A dealership should be the experts of their own cars. Not just another part replacer. I thought that was the reason they charge so much more?

Hi Dan, thanx for your clear diagnosis on our car!! And also thanx for your quick reply on our additional questions. Clearly the BMW dealer (Dusseldorp Zwolle) needs to do some extra learning on diagnostics. Let’s hope the mechanical damage is not too severe. 🙏🏻

Nice video and great diagnosis. Wow, that dealership tech was terrible. When you start asking the customer what part they should replace next you know they have no idea what they are doing. Very sad.

having worked and managed in dealerships i can say that the incompetence is created by the continually increasing targets that are set and the need for "efficiency" over quality of service. Most of the techs want to do a good job but are just not given the chance

I had no idea how fuel pressure was controlled with mechanical high pressure pumps. Thanks for the super informative video!

Learned so much from your channel. I could watch your videos all day long, far best automotive diagnostic channel on yt.

Get video Dan! Not many auto repair technicians holding jobs today have been formally trained to perform real analytical diagnostic procedures. They are simply parts-swappers - dealerships and indies alike. Perhaps this is the fault of particular dealerships or indies that do not require this skill level, or do not want to pay for it. I suspect the latter in most cases. It is refreshing to follow your approach to correctly diagnosing problems, seeking the root cause and not getting caught fixing symptoms. Your approach to diagnosing these problems reminds me a lot of how Ivan at Pine Hollow Auto Diagnostics approaches similar issues. Thank you for taking the time to share these experiences with the community and hopefully some of those in the community that are professional wrenchers will take away some valuable lessons that they can apply. Cheers!

Great walk along, and great diagnostic steps! I have had plenty of N20 BMW's that do the same and never log timing codes, it always blows me away. P.S: I understand that you stated this is an interference motor.... but I can tell you now that from the sound of it and from the scope capture there is no valve damage. The fact that both valves are able to seal some psi to create the towers and then also have the ability to release psi, means they all can seal properly and relief properly, meaning all have good contact on their seats just all timed incorrectly, hence the same sounding cranking noise. If you were to do relative compression with no sync, you would get all even humps and not ever realize that the humps are the same but lower psi from being out of time. Again, even if you were to add an ignition sync (at least with the N20's) it some how on bmw's can still show up proper location on relative compression capture, so you would be lost thinking it is in time based off relative compression test and just not ever know that it is off time and the humps are just lower than desired compression humps. You would have to take a physical psi measurement to realize. Don't' ask me how I know, I learned the hard way on one lol. thanks for sharing as always. 👍👍

The best Mechatronist I have seen so far!!! Once you see Dan at work, you fall in love and want a job like this. Well done Dan! Good luck!

Thanks Dan for another educational diagnostic video. Lessons learned; validate problem, don't believe anything, good tools make a difference, BMW interference engines are expensive to replace.

Thanks for running through that diagnosis, definitely a gotcha on the fuel pressure thing. How that timing issue was missed by two shops is amazing, it cranks way too fast, I would have instantly done a compression check.

Another great video Dan. Did anyone think that the spark was a bit intermittent? Would be interesting to see a waveform of primary ignition against crank sensor.

OMG Dan. That's a big dealership fail. 100% sure there were "timing off" codes while the car was stranded! And the second shop made the same mistake too. Unbelievable! And they know at the dealership the N13 does have timing chain problems. In my opinion, BMW 4 cylinders have been bad engines since 2004. It started at the N46. But the B48 and the B46( B58 minus 2 cylinders)are a lot better engines, finally. And I know there were bugs in some ECU's. My 2009 335i has a permanent 2AAF shadow code. I replaced the low-pressure fuel pump, the low-pressure fuel sensor (with the upgraded one), and the fuel control unit in the tank too. The car runs great and the low-pressure fuel is okay, when monitoring on the PC, but still has the same shadow code. The car runs great, no problems. Great job Dan. Have a good one and thanks for sharing. Dutch regards Nico.

Another very tricky one Diagnosed with Champion diagnostic work. Well done Dan 🎉

You are without a doubt a very thorough and knowledgeable technician. Well versed in the systems and nuances of computer controlled interfaces in vehicles of today. Amazing to watch you work through a diagnosis. Your videography is spot on as is the scripting, editing and presentation of subject matter to your target audience. All around an amazing channel sir. A 1000 years ago I was a technician in a German automobile dealership and was pretty good at my trade, times changed and I moved to locomotives to fill the need to be covered in grease and grime for a living. Now I live vicariously through channels like this one to supply my need for slipped wrenches causing a visit to the ER for stitches. Not that my subscribing makes a lot of difference to your already well tractioned channel, I have and will enjoy your overly energetic explanations of electro-mechanical interactions and diagnostic techniques.. :)
