Thanks for that tip! I'm due to clean mine.

@sliceoflife1821 most people say every 5k oil change but i checked mine after 500 miles and it was sooted up already most people just use the oil change routine as a base line but don't know how bad the map sensor soots up so quick

@@fredwilliams7893 Yikes, you have me convinced to clean mine this weekend! Thx

@@sliceoflife1821 use maf cleaner mass airflow cleaner you will be shocked how much soot is on it. The tip of the sensor will look like a small blue bulb when it's clean

That could be your NOx sensor at the diesel particulate filter. Letting off on your accelerator while going down hill is very similar to the same issue with John Andrews in this video: th-cam.com/video/lnf5SH3oB4I/w-d-xo.html He does a real good job explaining the steps to get the ECU to cooperate and engage the regen to clear the issue after changing the sensor. Maybe that's close to your issue. Best of luck!

Wow! So glad you got it assembled back. Brazil is a beautiful country and I have it on my bucket list to visit someday. Way to keep that B5 rolling!

Great question. The removal is shown in this video around the 20:22 mark: th-cam.com/video/i7CQV5NVnSo/w-d-xo.html Adding the vibration from the hammer drill makes it much easier. Good luck!

@@sliceoflife1821 wow, thank you! Great video

@@ExpatJoel Glad it's helping you out. You got this!

Sounds like you have the same symptoms as I experienced. I would replace it or have it repaired. If you have another ride for a couple weeks, you can send it out to Module Repair Pro linked above in the comments.

@@sliceoflife1821i will buy new module and screw old one out and put new one in just the windscreen tank is bullying my space😂

Best of luck Sebastian!

@@sliceoflife1821 thanks alot

This video was shot at two islands ranging from 1.5 to 2.5mi up river from Alexandria Bay's downtown area.

That's a good catch! I read articles about them using dummy (inert) bombs so they could test accuracy of impacts. If they were live they would obviously lose their target along with additional environmental issues.

Great question. I did hump the terra-cotta at first in whole sections, but they are crazy heavy and awkward. So I later tried to break them carefully and it was very easy. Just hold one of the sides and lightly tap about a foot or more lower and it will break off in your hand (to avoid a mess down below in the flue). You don't need much force. I remember using a plastic hammer to spread the load on impact. Glad the video is helping you out and best of luck!

Sorry I forgot your second question. My roof at the chimney base is very flat so I didn't tie-off when working on the roof. When using the lift I tied off to the lift's designated location with a shock-absorbing lanyard from the full body harness. If I was on a steeper slope, I would have tied off using the nailed or screwed D-Ring plates you can get at most stores and attach it where you would have to repair/replace the shingles or a better location. Make sure you have good lumber beneath the plate, not just plywood. I don't trust long ropes, especially over peaks. Too much can go wrong. There's more detailed and proper direction from the tie-off plate manufacturer you choose. Definitely a "follow the instructions moment". Stay safe and good luck!

I'm glad you liked it. It was only the fifth time I flew that drone so I apologize it wasn't smoother. If we get back out there this summer, I'll make another fly-by.

Sorry to hear about that cover. I didn’t have anything in my way. I wonder if they had issues with debris grabbing the wires or infiltrating the Bosch electronics. Sounds frustrating!

Looks like you can buy it on Amazon now for $145.

Sorry to hear you are having issues John. Totally understandable as it's very hard to avoid smearing the sealant. If you haven't already tried this, get another pair of hands to guide one area/side while you can concentrate on the other. Hang in there. You will get it done!

Thanks for the kind words Nick!

If I have misled you I apologize. There are many terms assigned to these sensors and with the implementation of DEF systems in all new diesels, the names get a little scattered and splattered. Bosch, who makes this sensor for GM calls it a Particulate Matter Sensor. I'll add that as an "a.k.a." in the description and add "Exhaust" to the title matching the other vendors (including GM dealers) that sell this sensor. With my truck approaching 5 years now, I'm due to get the service manual and will research the other sensors throughout the whole exhaust for terminology and function. The bottom line is this sensor is for soot calculation post DPF system for the computer to calculate the need for regeneration cycles to heat and clean the DPF. Thanks for making me think about this more and good luck with your repair.

Sorry, it's Saturday morning, I now see my 2017 is hitting the 7 year mark. Time flies when something's so reliable!

Awesome. Thanks for the input!

Your welcome and glad it helped!

Thanks for the compliment Russ! Just open the description and head to the related video on the regen procedure I performed with the Launch diagnostic tool. That should help you out. For my sensor replacement, no additional programming was required. I doubt your Colorado's diesel would require it. Good luck!

Hey Lucas, I'm sorry to hear your 2019 is having the same issue. I've had no issues since I change the sensor and performed the service regen. I had to get mine from the dealer so it was painful on the wallet, but worth it. I agree, there are so many different models on the net that look like a match, but just make sure the dealer confirms you have the correct replacement. Your 2019 will be rolling smooth again!

I use the Launch X431

I had a P1478 DTC. You can see more by opening the description above and linked video for more info.

It’s the Launch X431. I’m sure they have newer models now.

I'm stoked the vid helped you out! Enjoy your Flex!

P1478. Check out the description above for more info. and a link to the regen video if needed. Good luck!

So glad the vid helped you!

Many thanks for that tip!

Good question. I should post this above in the description. It was from Amazon and here's the link: www.amazon.com/gp/product/B07BH22YCR/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Glad this video can be a resource. Good luck changing them out!

Thanks for the kind words! I'm overdue posting some new vids on the Rover. What an amazing car!

@@sliceoflife1821 Yes indeed. Love mine

If I include the time to place the car up high on jack stands, prep the back engine mount, disconnect the drive shaft & exhaust, and loosen the front mount bolts, I would say that was one long day around 8 hrs. Now I'm not a pro so I don't have the instant knowledge of tool size and technique, so surely the pros can do this in just a couple hours. The actual lowering was just a few minutes of very slow releases. I hope this helps.

Even though it was sunk on purpose it is still sad for everyone who served on her and had to watch her go down

Yes, those manuals are hard to find and many times the price can be ridiculous. I hope your project goes smooth!

No reset or reprogramming was required for the sensor replacement. It was smooth and easy.

@@sliceoflife1821 Thanks for the reply. BMW is clowning me saying I need to reset the vehicle adaptation before they will warranty the DPF.

There's a good chance, but since you should still be under the 5yr. warranty for that motor, I would let the dealer decide the next move. I've heard from others, they usually start with a service regen and see what "bakes off" and analyze each system for flow. Good luck!

@@sliceoflife1821 thank you! Who can I find to do the regen??

@@1961suzieq Glad to help. Just take it to any Chevy dealer and they will perform the service regen. for you. They may also have other techniques to analyze your cats versus the other systems.

I have the same issue dealer won’t do a service regen to see what happens they just want to replace the whole filter… still under warranty tho, but DPF filters are on back order thanks to the strikes

I lost all communication with the ABS module, so I don't remember a specific code with loss of comms. Many months before this, I do remember a code trip on the brake fluid pressure sensor. That is actually the circuit Module Repair Pro had to re-soldier. Hope this helps!

The most repetitive DTC (check engine light) code I received before this change was P1478 "Particulate Matter Sensor Temperature Circuit High Voltage". Yes, the Launch diagnostic tool (X431) can check and clear fault codes before or after service procedures similar to most diagnostic tools. Good Luck!

That's a good question. I don't see bolt specs in my manual. I'll try some other resources. Does anyone else know this answer?

Glad to hear the video helps. I bought the Bosal exhaust system from Rock Auto. I just searched and it looks like they carry different brands now. The car and exhaust system still runs great 4 years later. Best of luck!

Great question! At the time I performed the repair my diagnostic tool did not have that option, so I just bled it manually. No issues encountered. Best of luck!

@@sliceoflife1821 All done, it definitely seals up the tank now! Thank you for showing the leak! It was very helpful. After repairing, I feel more confident in troubleshooting the EAS. The system is quite basic and people take it more of an issue than it really is. I used a leftover spare a/c line o-ring from a box bought at autozone. By the looks of it, this o-ring seems like a common issue as L322s age based on how it is fitted. The fitting has no indent for the o-ring to sit in. It literally seals between the head of the fitting and the tank. It's a bit baffling to me since o-rings are usually fitted inside the lines (e.g. a/c and power steering lines). As the o-ring gets deteriorated over time because of this design, the issue will arise again. I would give it no more than 5 years before this fitting starts feeling questionable again.

Way to go! Glad the video helped you out and I agree, this will probably require replacing again in 5 yrs. Great points on that o-ring fit! You just saved yourself tons of money and have more confidence for the future. Enjoy the high!

Many thanks. I tried a new mic with wind sock. Some more tweaks with the settings this year should make next year's recording better. I need some steady-cam help too. The rocking was tough to hold the Angels in the shot.
