@@Diagnosedan Hello how are you I am interested in purchasing the annual access. But I can't do the subscription for ONE year. Since I am from Mexico and the entire American continent is not considered. Only United States of North America. Which there are also technicians in Latin America who seek information and help from other countries and websites. There is something very important that large companies FORGET. THAT SPANISH IS THE SECOND LANGUAGE MOST SPOKEN IN THE WORLD AFTER CHINESE. AND THE MONEY FROM SPANISH SPEAKING COUNTRIES ALSO HAS VALUE. SINCE OUR CURRENCY IS CHANGE TO DOLLARS, EUROS, POUNDS, RUBLES ETC.

You are mostly based on european cars yet I cant find anything about Peugeot, which is very common car manufacturer in EU. I have Peugeot 308 with 1.6VTi engine (same engine is build in MINI also) , and it is very specific engine with lots of things that can and do go wrong. So it would be very helpful if you make one video about that engine. What can we do about oil consumption (some says replacment of the PCV valve solves the problem but I kinda do not believe in that statement).

[@rondhole]

I did not see much toyota/lexus video in your channel. I think it is also related from the fact that they are rarely having problems.

[@ikocheratcr]

I wonder how much suffering the guy that discovered this fault went thru to create the bulletin. Great video, and love the part about DPF. I can only wish that where I live was obligatory, no car has it.

[@Diagnosedan]

It's very time consuming to find faults like this. Can take alot of time to figure this out!

[@htownblue11]

Well done yet again Dan! I had this vehicle and had this exact problem. Had I Not had a Lexus Tech on a forum tell me about the fan issue, I wouldn’t have been able to fix it. DDTSB diagnosed it in 30 seconds. If I was a pro mechanic, I’d jump on a DDTSB membership. Diagnose Dan = World class expert diagnostician. Facts.

[@sebastiaan5111]

Yes that’s a nice one. Only thing wrong is cm3 stands for cubic centimetre.

[@Diagnosedan]

[@johnmehaffey9953]

Dan once again you have educated and entertained me at the same time, love your diagnosis very knowledgable

[@kevinbain4361]

Dan, excellent diagnosis. It demonstrates that as independent diagnostic techs we need access to OEM tech info. It would have been interesting to see if there was any freeze frame data available with the DTC to see if it showed the battery cooling fans were commanded on at the time the DTC was logged. Would also have liked to see the current trace on the scope of the old fans verses the new fans could reveal any back EMF or perhaps some AC voltage leaking on to the DC circuit. Just thinking out loud here.

[@obsoleteprofessor2034]

One of the MIT open course engineering videos demonstrated what "noise" would do to a chip that is looking for s clean "yes/no" (1 or 0). The data sheets for semiconductors give you the tolerance for each particular chip. "0 or NO" may be from zero to 1.8 volts. "1 or YES" may be from 3.5 to 5 volts. If voltage spikes (static) are introduced into the line, the voltage may drive past the point where the chip goes past the tolerated voltages and the receiving chips don't understand what the transmitting chip is trying to say. Odd that all 3 fans failed at the same time. It could also be that the failure of one fan would not produce enough noise to drive the communication past the "threshold of misunderstanding", but once the 3rd fan failed, it was too much noise for the communication line to tolerate. If these fans have brushes, sparking will eventually occure as the brushes, commutator and bearings wear. Side note: My cousin worked in the Silicon Valley in the early days. He told me that a big part of the code written for any program contained tons of fault checking and data verification, ie, did you put in a number where a letter was required..did you enter that you were 20 feet tall and weighed a kilo (etc, etc). Dirty connections, broken wires from too much twisting, kinks, etc caused many communication problems. The "hand shake" contained tests of communication. Good video...showing the on/off waveforms illustrated the problem very well. I will post the MIT to this if I find it.

[@danthemann6565]

Why not try a capacitor Network to reduce the noise the fans are producing?

[@danthemann6565]

In other words, parallel the right capacitor with the fans to reduce noise

[@Diagnosedan]

Thanks for the great comment, i'll do an update when i've examined the old fans

[@go5582]

hi professor, please continue to comment your digital theory's behind the digital issues. great comment and well, easy to understand. thank you .

[@vidselih]

@@danthemann6565 Hi, yes, a noise filter would do the trick, a simple LC (or a snubber circuit, or both) would "swallow" the noise created by the fans. And probably cost peanuts compared to three new fans.

[@DanTodmto2]

Thank you Dan. my 2006 RX 87000 miles had exactly the same problem. you are an amazing and excellent professional.

[@letmein2460]

Brilliant again! I wish there were more people like you who really knew how to fix things instead of acting like they know when they are only voicing their opinion on how to fix the problem. This is why you get these jobs because the parts canon has sometimes been used and the problem still exists. Great job again, per usual.

I have been in the trade 19 years now and I'm always learning new things. So glad I found your channel.... I used to work for Citroen/Peugeot so I was intrigued by the video you did for the 208 Peugeot you did with the Cracked cat.... I have some good information in regards to common faults on that particular engine. AND also the 1.6 EP6 engine... If I could pass on that info to your DDTSB. Just let me know.

[@Infiniti25]

Peugeot/citroen - my sister had a 1996 Peugeot 306 that I learned to drive in and she always said French cars are crap for electrics and brakes. How are those two items in your experience? I did end up getting a year 2000 Peugeot 306 as my first car and also had a 2004 Peugeot 307 estate. I found I was less impressed by the suspension than brake issues but the 307 did have a COM2000 unit issue which was under warranty thankfully.

I gues, the bearings is gone on them, turning get's worse and rotor contacts goes sparky, sparks create heawy noise and load induction on all wires nearby.

[@Tininppa]

only 90t km on those blowers... so you need to change them every 3 years if you use the same motors... or are there some changes in the new ones. Some dc motors make carbon dust and start to make weird things but are these more ac motors whit own controllers? i hope those motors are still in warranty

[@celeron55]

I would guess they are DC motors and the brushes or commutators are gone.
