[@fieldsofomagh]

One of the best channels on car repair.

[@Diagnosedan]

Tom OConnor, Wow buddy! Thanks you made my day😉

[@georgek8959]

DiagnoseDan Hello Dan, i'm following you a few months. I like the way you solve the problems. I need your help. I have a passat 2.0 tdi model 2008. Two days ago,had a problem with electric power steering. The code is 00569 and the description:current on the steering motor, electrical circuit permanently open. I would appreciate any help. Thank you for your time.

[@Diagnosedan]

George K, I would like to help of course. But it's tricky to go just by codes. To know for sure what's wrong a proper diagnosis must be performed. The electric motor,Power and grounds need to be checked.😎

[@georgek8959]

DiagnoseDan Thank you very much for the immediate answer. I will ask my enginneer to do a check .☺

[@rosendomedina8933]

totally agree sir !!!

[@kalimsafdar657]

Alot of garages might have jumped straight into replacing coil packs/ plugs/ injectors or even fuel pumps! Dan always demonstrates how important it is to take your time and interpret the data in front of us. Genius as always Dan!!!

[@Diagnosedan]

Thank you😊👍

[@Crushwokery]

Dan, you're amazing. I am an avid watcher of Scanner Danner and have learned a huge amount from his channel. Thing is he mainly deals with US machines, very nice but not relevant here in the UK. So when I found you it was gr8 to find someone just as amazing as Paul but on cars relevant to Europe. Huge thank you for everything you share with us. Gr8 vidz, educational, entertaining and fun to watch‼️

[@Diagnosedan]

Wow thanks Alec!👍👍👍👍

[@nicksautorepair6936]

To further support Alec's comment, I'm in the states and I'm a scannerdanner subscriber too. I think I've watched all of his videos multiple times and I have his book. Danner's video's have been very helpful to me as I do work on many of the models in his videos. He's excellent. I'm a man that can admit to my shortcomings though. The European cars have been a challenge to me. Until I found DiagnoseDan, I was kind of lost when it came to vehicles on the other side of the pond. lol. I've always known the Euro cars were essentially doing the same thing ours are, I just didn't know how. Thanks to DiagnoseDan, I've gained a huge amount of knowledge and a FUNDAMENTAL understanding of these systems. I'm no longer worried about taking on that BMW with a weird running problem. Thanks to you DiagnoseDan!!! YOU are definitely the European version of Scannerdanner. Coming from me, that is the highest compliment I can give anyone in this field. Thank you! Keep the videos coming. I can't tell you how much I appreciate the work you're doing to help all of us.

For my sins, I went and bought a Benz CL600 m137 2002 that had been sitting for 4 years and before that, zero maintenance other than oil and filters. It was a non runner. It has symptoms in symptoms and issues that have compounded and spawned new super issues! Finding this channel is my saviour

[@CT-qx8nl]

As a machinist and engine builder, and one who loves diagnostics, Dan you have an excellent and thorough way of explaining everything. My former boss/mentor was the same way. Keep the videos coming.

[@1jeffr]

I'm not quite sure how a stumbled upon your channel, but I'm glad I did.

[@Diagnosedan]

Welcome Glad you did😉

[@BrokeLogic]

I know what brought me here, but after this video, I'm feeling the same way.

[@SaiRam-hu8ly]

Dan sir, you are officially a Master troubleshooter. Your analysis of scan data and pin pointing the problem is bang on. Thank you for taking the time to explain the whole process of finding the exact problem and component and explaining it to your viewers. This definitely is one of my favourite channels!

[@gordendavis3585]

In the army they use the sledgehammer to fly approach, replace the entire engine with a new one.. LoL 🤣🤣

[@Aardvark49]

I'm a DIYer who just discovered your channel. You're helping me learn a lot. I really like how you explain how to find the cause of a problem.

[@arga1966]

What a guy Dan is. He thanks us for the good comments in the previous videos, when it is us that should be thanking him for every video this Legend makes and shares with us. Thank you DAN. 🤗🤗🤗

[@rimmersbryggeri]

Suggested one of youe videos for use in my class tomorrow becasue we are doing a course on the subject and youhave a really good diagnostic process. Thanks for taking the time to make videos. You just dont come across all possible problems in a school setting like you do in an expert shop like yours.

[@Diagnosedan]

Where are you from and what do you teach?

[@rimmersbryggeri]

I am swedish and Im a student not a teacher. I was a little disapointed that my teacher didnt use your video. It was only a HVAC orientation course though. I do teach swedish to immigrants on a voulunteer basis though. We have cars in the school to work on but not enough to have the possibility to have a wide range of faults. That's wher guys Like you and Eric O come in, sharing knowledge really is valuable. Are you dutch or belgian?

[@Diagnosedan]

@@rimmersbryggeri I'm Dutch! Thanks for the comment!

[@ezautorepair5143]

Thank you Dan. Don't know if I'll ever make it as a auto tech, but its fun watching. LOL. that look on your face when you did the brain work finding the vacuum leak and now the grunge work of fixing it. Great videos

[@Diagnosedan]

Thanks!😉

[@laurentvigneault-pinard1634]

Holly shit, I'm really impressed! You've got some serious diagnosing skills man

[@christophermohamed4990]

This weekend was a special one for me. My daughter turned 8 and we had an amazing birthday party for her. And also I discovered Diagnose Dan.

[@vadmalski]

His viedeos are much better and clearer than other "native" speaking guys, love his calm and steady speach and showing stuff clearly.

[@zeke112964]

Like the way you take the time you explain every step you take and the details....nicely done! As usual the Germans over engineer their intake....must have been expensive to replace

[@Diagnosedan]

Yes it was😔 Thanks for watching my video's it's appreciated.

[@richardbeckwith4545]

Could watch and listen to you all day! Brilliant, thanks Dan, please keep them coming!

[@alessichris07]

You are hands down the best. Your videos are top notch . I’m learning a lot of information from your channel, thank you.

The best auto repairs KZbin videos I have ever seen. right now I am working on communication issue with drive train CAN on my Mercedes C250. Thanks you DiagnoseDan

[@salem222333]

You have shown a remarkable failure analysis, thank you Dan

[@Diagnosedan]

Thanx!

[@charn1]

Fantastic video Dan it's good to see repairs done on European cars. Your very informative and a great teacher. Much respect from a lifelong professional Tech in the uk👍

[@Diagnosedan]

charn1, Great comment comming from a professional! 👍

[@joseesparza9757]

Been work on my w204 C300 for about a 2 weeks looking for the misfire and this video really helped me out a lot. Thanks for this piece of knowledge. Just ordered a new intake right now

[@djmech3871]

What did the new intake manifold cost. Mercedes plastic must be expensive?

[@stuartlade6611]

I would hate to know how much that intake manifold costed 😭 Solid Diagnostic work Dan! You're a weapon and awesome to watch 💪👌

[@wahabaltahin7515]

How beautiful you fix Dan, hope to visit your shop in a day

[@Diagnosedan]

😁

[@prestigefleet]

You have been by far my favorite KZbin Professor! You not only analyze customer inquiry but then walk through the troubleshooting procedure (In Full In depth Explainition which is Amazing) find the issue (Aswell explaining the reason why point of failure) repair the situation at hand and the fully confirm it working! Seriously you have made me a better mechanic, thank you so much for what you do!!!

[@BrokeLogic]

His intelligence goes beyond engines. This guy speaks really proper and clear too, even using hand gestures.👍🏾👍🏾👍🏾

[@nicholaswatson3896]

I'm so pleased to have discovered your channel. Your videos on car diagnostics are by far the most helpful I've viewed, and I've watched a lot. Thankyou for sharing your expertise and knowledge with us.

[@DrJeff-vn1st]

Just found your channel tonight, binge worthy!!!! Every tech needs to think like this, follow a process that reflects on how a system is designed and the symptoms should lead to discovery...... AND!!!!.... confirmation that the original problem is actually gone after the repair!!! Great job Dan!!!!

[@Itisinthehand]

I'm a builder hoping to learn sufficient to stay informed and maybe do some of my own work now. I bought a 2008 6 series and the day after purchase engine management light diagnosis was for 6 new injectors. My garage allowed me to do the job at their workshop. This car was meticulously serviced by BMW- they told me. Full service history from them. However, when I found they had mixed injectors contrary to their info spec, and the air filter was many years old ( it was date stamped ), the trust dwindled. Recently I drove it through a ford and a load of lights came up afterward. Some guy diagnosed it saying it was not worth repairing. 6k waste of car. I don't think so. My garage don't seem interested. So here I am loving your vids Dan.

[@jimmyjordan435]

wow another humble professional soft touch of the good Dan man

[@Diagnosedan]

😀

[@ejjr5046]

Dan you saved me time on the c300 I bought for my son. After throwing coils and plugs at it ( never a bad idea) I still had codes. I ordered injectors (also not a bad idea with 108k) and after getting the fuel rails off and wiring loose enough, I figured the intake is much easier to R&R at this time. Sure enough the valve that controls the butterflies on the intake runners was completely broken. Much easier that reassembly and them removing all togas tedious wires and vacuum lines I’m well versed with American cars, you saved the day

[@alanryderb]

I think that a P0300 code means, time to remortgage your house mate cos this is gonna get expensive. Great video.

[@Diagnosedan]

Not always! 🤣🤣🤣🤣.

[@techgamer1597]

sometimes its just spark plugs in which case its dirt cheap to fix.

[@gregleithoff5943]

Hey Dan, your style of diagnosis is the RIGHT way. I work for a fleet that runs on CNG and the misfires are so bad all we can do is clear and ship. Keep up the great learning experience!

[@Theag393]

I cannot think of a better channel on auto diagnostics. Keep up the excellent work! You are an excellent teacher!

[@Diagnosedan]

Thank you Fabio!

[@smithpwm]

The reason I like your channel is how you narrow down and find the rootcause, keep up great job and share more with us, bro.

[@shaunbreslin6360]

@@ac0rpbg most cars have a variable intake, its to improve power and torque at low engine speeds by improving volumetric efficiency.

[@Texasknowhow]

Shaun Breslin - I need to read up on these intakes, wouldn’t the throttle body be responsible for the amount of air going into the intake? Why would it help to regulate the flow inside...?

Great case study Dan. Thanks for sharing. Steve.

[@Diagnosedan]

Thanks Steve!😉

Diagnose Dan Fixed it AGAIN !! Lol Great video showing the importance of scan data and the understanding of how o2 sensors work .

[@Omardottcom]

Dan is the master. 😂 He gets a thrill from diagnosing and finding the problem… fixing it on the other , boring. That was funny. I was looking at getting a GLK with the same engine, then I found out how problematic the intake manifold are with all the plastic pieces that break. And boy is Mercedes great at making plastic that break. Decided to go with something else.

Thank's appreciate your comment Wil ! Especially comming from someone who knows what he's about!👍👌

[@oda0111]

Good job Dan! Glad to see you working on Mercedes, I might find something I haven't dealt with yet. The M272 and M273 motors are known for having issues with the variable intake runner manifolds, usually it's the little rocker arm connecting the middle vacuum actuator that breaks or one of the actuator shafts or a combination. So I guess 10+ years is the most lifespan one can expect from this intake manifold. It's kinda bad, they are quite pricey.

[@Diagnosedan]

Alin Marinescu, they are pricey. But better than taking the risk of the loose parts inside the manifold being sucked into the engine!

[@oda0111]

Oh yeah, you definitely don't want plastic flying through your intake. I just cleaned mine really well, degreased and tested everything and so far it's doing really well. It probably has another couple of years left in it until it bites the bucket. How many kilometres did the M350 you worked on had?

[@rrvtechcon115]

Dan, I am very impressed with your video. By the way, I have a 2009 ML 320 Bluetec with a persistent fault code P0101. Replaced MAF sensor, air filters and calibrated the ECU to adaft to the new MAF sensor & air filter at the Mercedes dealership shop, fault code disappeared for a while but after 2 months at the middle of traffic jam in a hot summer day the same code appeared again. I deleted the code but keep coming back. I do not want to come back again to Mercedes dealership and spend another $1000. I appreciate if you could give me some hint. I will just try to trouble shoot it myself this time. Did not find any leak on turbo discharge pipe joints as well as the inter-cooler inlet and outlet connections. No hesitation, idle is excellent, did not noticed any power reduction or increased fuel consumption.
