Great video and I loved watching the troubleshooting journey learned a lot! Although I would recommend saving yourself and the customer time in the future with these codes and and tailpipe soot... When the computer throws these codes it's related to the low pressure EGR circuit, you also could easily notice there was soot in the tailpipe. What this means is that the vehicle has a cracked DPF filter. It may also be clogged too, but soot in the tailpipe is a telltale sign that the DPF mesh filter has been cracked and is allowing soot to pass through to the mufflers. Even if you had a clogged DPF, it would not allow soot to pass through into the tailpipe. This is an extremely common issue with these model years, the DPF is a consumable part that is not meant to last the lifetime of the vehicle, they go for about 100k miles.... and eventually they will crack. They can also crack because of faulty injectors causing too much heat in the system. You could probably make the engine light go away for a while, but eventually it will throw the codes again and it will clog up sooner than later. It's extremely frustrating that the EPA has put so many restrictions on diesels like this.... If you replace the DPF filter make sure you also replace the EGR filter at the same time or clean the EGR filter, that thing is probably clogged up as well, theres also a low pressure egr valve back there that could use a cleaning too. You might be able to use egr cleaner and spray it into the exhaust manifold but usually that doesn't seem to work from what I have seen. This is what I was able to discover through my own research on these jetta TDI EGR systems. I own a 2013 Jetta TDI and have the same codes. Did you try redlining the vehicle to see if the computer forced the car into limp mode?

I like your content. You explain thing really good and simple. I have learnt many things from you. Such as electric, dpf issues

Excellent video, I have deffinately learnt something today. thankyou

Excellent video,very well explained again.Thankyou.

Continued: I meant before taking the vehicle for a test drive.

Hello friend, can you filmed the process for remplacing de Dpf please ? 😎hello from France..👍

Why didn't you activate def regeneration using the Auto scan tool. i know that the scan tool does not allow dpf regeneration when there are trouble codes, but the DTC that you had had to do with brakes. the scan tool does take the def to more than 600 degrees Celsius .

Boss you are right

It is good

What could be better to replace the EGR or the DPF FILTER?. Do you have a video of the DPF replacement?

Hi mate I'm from Belfast I want to get in thouch with you many thanks

Hey there

What was the DPF deferential pressure after injecting the cleaning fluid and doing the test drive that brought the soot content down to zero? You should have taken it on a 30 mile road test driving with mainly low gears. If the car is not on limp mode with reduced performace(the car can still rev past 3000 revs all the way to red line) then the DPF is still good cause if it is blocked the car will be on restricted performance. Oh and next time don't drive with one hand and video with the other hand for content, it's very dangerous and not worth it, we your viewers believe you, so just explain your test drive results after..... Stay safe bro!!

General you need to get a manometer to read the dpf and stop using that rubbish dpf cleaner and use launch cleaner instead
