I was a tech at VW/Audi for 47 years in the salt belt and have seen my share of green, I would have thought you would see more of it because of floods. Good diagnosis. I just subscribed.

[@robertparamore2863]

I love these jobs. I always start with what got changed. It's usually always shade tree related. The problem is that the fix is always simple. The hard part is making sure you have the right info. I spend hours finding the right components because what i see and what alldata and mitchell show are totally different. It's hard to make money if you are chasing wire colors. Thanks, guys, and you, professor. You take the time to fix it right and share it with us.

[@LynxStarAuto]

With Audi/VW it's always best to pull the diagrams directly from the Erwin website. All the aftermarket diagrams are wrong on these cars or missing data

[@fabi1013]

100K get you a silver play button. it’s very interesting to see how people work on Audi. i’ve been working on Audis for the last 8 years at a few different dealers and i like to see how people take different steps with them.

[@melindawillever9546]

Submarine Service Electronic Tech did you say “Green crusties” 😅😂 Always start at the tampered module in the circuit. Always look for physical damage first then break out the multimeter. People just don’t understand that water, salt and electricity don’t mix. Always keep all your drains clean and don’t create water deposits where they don’t belong. Enjoyed watching.

[@HoodRichSWERVE]

The reality is most dealers / shop don’t even come close to the level of care and experience that is shown in this video :( It’s the norm to scam customers these days… I’ve wasted over 5k listening to them and every, single, time… my problem remains and nothing is improved or different… infuriating

[@tonyloyd7174]

Absolutly no worries about the audio.....you know some of us appreciate the ASMR aspect of it.

[@RideBikes_Walkplaces]

Had so many audis and vw' s over the years with blocked drain holes on the bulk head causing water problems! Also the old corsa d diesel had the ecu in the drain on the bulk head. Madness! Grat watch buddy, hi from a wet uk.

[@Liferoad371]

As soon as I saw the K&N filter I knew this was going to be a problem child.

[@DJ-tn7vj]

This is why I made some slight modification to the Uactivate by adding relay harnesses for the break out leads. This way I can test the relays directly with the tool

[@majkosk8x]

actually you can test relay without special tools

[@DD-gd3fr]

Amazing catch 👏 kids modifying there car sometimes spells trouble. Really great job!

GREAT VIDEO ,,, JUST ONE QUESTION FOR NOW WHICH TOPDON SCANNER IS THAT THANKS ????????????

[@stitchbmx]

That is the top don phoenix lite 2. I have the same one. It is a great scan tool.

[@theroyaltyautoservice]

Phoenix Lite

[@willpurser3208]

Relay test kits are great for testing if a relay is outputting, don't have to guess and try sticking multimeter lead down the back of it - If you're unaware, saved me plenty of times. Lisle kit is really good - 69300

[@raymondganczak4533]

Great video as always. That uactivate is an amazing tool once you get the hang of it. When you had it plugged in I noticed the LED at the bottom on the control side was not lit. If you would have wiggled that adapter down in then at control LED would have lit to let you know you had contact.

[@johnbonifas6040]

Awesome video I see the green crusties a lot like Eco says.

[@JettaRedIII]

At the very beginning of the video, there was liquid in the little recess in the fuse cover. I'm thinking, water got into the fuse block and messed stuff up. Mercedes are very susceptible to that sort of thing. As you said, I'm surprised the damage was not more extensive. But the story ain't over yet!

[@xxdaemonarchxx3436]

I love your videos sooooo much man. Could use a little editing down is my only critique. Keep up the good work!

[@catreyes4454]

Thank you for this video

[@Jpilgrim30]

I love AESwave and the Uactivate is a great looking tool and all but I talked myself out of buying one multiple times as it’s hard to force myself to spend that on a tool when I can do the same tests with a test light and a fused jumper.

Good vid. I could tell from the way you were laughing during the intro . it would be interesting. Really laughed about the too many tools. It's not the number, it's keeping track of the stuff you have. See George Carlin.

Extra labor needed to be approved probably. Also, needed to confirm the relay was/wasn't working.

My daughter bought a car from a "mechanic" who work at a GM dealer. You should have seen the half ass stuff this kid did to this car with the after market sound system. He ran big cables through the door weather striping causing the inside of the car to fill with water. he wrapped the main power cable counter clockwise around the battery terminal, instead of using an eyelet connector.

[@josephchamberlain9129]

Good diagnosis. Thx

[@KissTamas3]

Great job finding out what was wrong! The second I saw that the main EMC and all body electronics junction box was in the drain area I knew that it's going to be the problem. Just watch how the locating clips of the lid-hooks create a lovely path for the water into the junction box. No gap from the firewall that could prevent any issues. That is piss poor German engineering at its best. Sprinkle this with a bit of pure stupidity (an open lid of an electronic junction box in a drain area) and you have a mystery. "Dear mechanic I've been pouring water into my ECM module and main junction box and the car won't start now. Please help me to diagnose what's wrong." Very well diagnosed. FYI. You can buy a set of relays with just a switch on their top to isolate control/function site issues easily. You replace these with the original relay and you can manually switch on/off any circuits. I hope this helps.

That's a very common problem area on Audi's of that style. The way they had that ran didn't help but believe me it's just a matter of time before they have issues there. N let us see the codes next time and start the car to make sure it's good. So we can see.

[@g35silver]

I have a 2016 Audi A4 Quatro that uses 1 quart of oil every 200 miles. While driving behind the A4, it will puff white smoke when taking off from a stop light and then no more smoke. The PCV was changed; no help. I don't think it's rings since it doesn't smoke all the time. Would I be correct to assume it's the valve guide seals? I'm a pretty good mechanic, but I have no experience in this area. Thoughts? Is this something I could do myself or ????

[@bikerboy6985]

VAG cars keep those relays,fuses and ECU under the plastic connected to the windshield it’s crucial to keep that area clean as much as possible….why? So there are two drainage holes for water when does get clogged with debris guess what happens all those electrical components get damaged and will not for sure be cheap and easy fix don’t ask me how I know…

[@johnmac9055]

I have seen this also on Audis when drain holes in the plenum get plugged and the plenum fills w/water.

Be careful with the euro cars and those relay bypass tools sometime bmw, audi/vw will use a relay that has the same pin layout but the internal wiring is different from a standar relay.

[@GSRDUDE80]

I respectfully disagree with this as a blanket statement, poorly installed or cheaply made parts can make a car less reliable sure. People will always customize their vehicles, and have every right to do so, as long as it does not disable or delete any emissions equipment and have not made the vehicle dangerous in anyway to drive on public roads. For a dedicated track car or a display only vehicle you’re only then they are only restricted in modification by the class they want to run in. Back to modifications and leaving a a car factory, I don’t know your background or the vehicles you like to drive or if you even care what you drive. OEM’s need to build and install calibrations into the their vehicles ECU that can be used in all different climates and altitudes be it a North American vehicle or a global market vehicle. Often times they just don’t get it right and in many cases the vehicle reliability, performance, and drivability suffers for it. I’ve yet to see a vehicle (even some exotics) who’s drivability couldn’t greatly improved upon with a little simple smoothing out the some of the critical maps in the ECU. Then you get into the VVTI, VCT, VTEC, Mivec, etc systems or the Electronic Throttle Body maps and simple safe adjustments to these can make a car a lot more responsive and a safer car is one that you can give you confidence when accelerating and braking This goes into parts added to you vehicle, which in the case of many of the newer vehicles on the market are now coming with turbocharging from the factory, you want to discuss reliability and consistency. Take a new GDI with a turbo for instance, problem one they are gasoline engines that are direct injected. Fuel injects directly into the combustion chamber not into the intake manifold through the intake manifold. Unless you have a walnut blaster machine to clean these valves or are pulling the manifold in some sort of maintenance interval, you can damage that engine, funny how none of the manufacturers have this listed in their maintenance specs, speaking GDI especially ones with turbochargers, all GDI vehicles come with the risk of a phenomenon called LSPI, which is another engine destroyer, 3 of the best possible things you can rod to prevent are - Never lug your engine along meaning load at low RPM, -Install a Air Oil Separator or well designed set of OIL Catch Cans to stop all that crap getting run back through your engine increasing potential for not only LSPI but carbon build up a So -Change your oil often, very often, no more then 3k often, which your manufacturer tells you 6, 8, 10k. You’ll be lucky if your car makes it to 100k. For a GDI engine you’re safest to choose a proper 100% Synthetic oil of the Group IV, V variety that’s been tested extensively and has passed GM’s LSPI testing guidelines. Which are oils that you’re not buying from, your local Walmart that say Full Synthetic. Full Synthetic is NOT 100% synthetic oil. -Lastly you can help to combat against LSPI with some good ECU mapping, BTW im 44 and one of my modified vehicles is over 20yrs old, has never left me stranded, and is making 2.5X the factory claimed HP and TQ figures to the tire, and still has the 100% factory drivetrain and block, con rods, and pistons. clutch and cylinder head are upgraded with better then factory components as well as is every suspension, fueling, amd ignition component in the vehicle. Key is to maintain your vehicle and it will last for you. Unless it’s a Kia, don’t buy a new Kia opening the door has been known to explode the engine

[@fabi1013]

as long as you purchase good parts and don’t do stupid modifications, i believe your statement isn’t necessarily correct. some tasteful mods can improve cars. there are a few mods on these vehicles that actually improve them.

[@johnrpizzaguy]

I’m with you on leave it alone,if the factory thought those mods would make the car perform better they would’ve done it themselves but what do I know I’m only a Toyota,Chrysler,Nissan and BMW factory trained master mechanic of 40 years and counting.

Scanner Danner did a YT video 6 years ago (dated Jan 20, 2018, titled "No Start Testing Basics - Spark, Injector Pulse and Fuel Pressure (Hyundai Santa Fe, kzbin.info/www/bejne/qaKTeX-Ies6hhLc )" in which he demonstrates the use of the older version of the AES Wave uActivate relay test tool. At 30 minutes to 40 minutes into SD's vid (as well as a laughable example of "expectation bias" at 36 min & 35 seconds in), and again from 49 minutes to the end, is far and away the clearest, most concise explanation of the use of the AES Wave uActivate I have seen ANYWHERE on YT or elsewhere on the internet. Both with and without the use of a scope and amp clamp. AES should stitch these two segments together just to show the tools versatility, and with proper knowledge to back its use up, also add speed to the diagnostic process. I love mine, and am shocked by many who bought it (incl the older version) and whom have never used it, or are maddingly, blindly unaware of its capabilities. Of course, one must have a full and clear understanding of automotive electrical theory to put it to its best use, and also not misuse it, or you could seriously damage components (similar to weaponizing a Power Probe if you don't know what you are doing) by sticking other tools into the banana jacks (doubling as test ports), like for example a Power Probe or test light into the wrong ports. Sure, if you've been around for awhile you probably are already doing the same thing with a test light and a fused jumper, like a lot have for years. But for someone who hasn't, and is also trying to speed up the diagnostic process, this works very well. In Sherwood's case here it turns out the real issue was the relay / fuse box connections underneath, but the uActivate (or a fused jumper wire and test light) can help to prove or eliminate other causes. Also, please get rid of that 190 or earlier Relay Buddy & update to the newer version. They often give false readings, as they do not load the relay, and drove/drive a lot of people crazy chasing their tails when the tester shows a relay "passes" as good. The newer version, the 194 (or 195 kit) actually put in a small load and are much more reliable. I literally threw my old 190 in the garbage when I got the 195 kit. Same goes for the newest Lisle mechanic's stethoscopes (the ones with the bellows in the middle). They absolutely blow away the sound clarity vs the older versions. Again, tossed my old Lisle's ears in the trash after getting both versions of the newest stetho.
