Great video of exactly how I tackle these cars aswell but why didnt you go to the forced regenration on the diagnostics. it tells the ECU to hold the revs. Reason am asking is you obviously have your own very good tried and tested ways to do your repairs. I go straight to forced regeneration once everything else is good to go.
I own an audi a6 c7 2016 2.0 tdi with 190 hp! In city driving, regeneration starts every 100km! The car has 200,000km! He has not reported any errors so far! I would like an answer if this is normal or if I need to see a car mechanic!! Thanks in advance!
As long as it doesn't give you an error message, then all is fine. It depends from car to car. You can't say there is a right way of regening. Every car has been programmed differently. Our citroen c4 does it every 200km or so. We had a volvo before and that did it every 150km's. So all depends.
I dont think it is a cause of short journeys. I had zafira 2015 170bhp automatic and used it for minicab. Never had any issues regarding dpf, only thing I assume is the manufacturer using sofware for dpf.
This depends on how the manufacture programs the DPF. We have a citroen C4 and even though, we do many times short journeys, the car does a regen although you can feel the engine accelerating a bit more, making more noise and vibrating a bit more through the steering wheel and in the rear view mirror you can see some gray/black smoke. If you read it with the OBD reader you can see that the car sprayed some DPF additive and then did a regen as the last one was like 200+ KM ago, because we haven't done a very long journey on the highway, only short journeys. So it all depends. I pressume your car does the same thing (when driving short journeys). I guess that some other cars manufactures programed the DPF in a way that it can't regen below 500 degrees, even with additive or not. Just to save on the DPF's life cycle as regening on lower temps does wear the DPF a bit more than when you take it on the motorway everyday. So because of that the car automatically gives you a message that it can't do a regen and the car goes in limp mode. I have the feeling this is only on asian cars (honda, toyota, mitsubitshu, etc). I don't know why they do that. But I could be wrong too, this is just my opinion.
you may be right regarding asian cars, the only thing need for regen it optimal operating temperature. Now I have skoda octavia it was not doing regen and egr was blocked due to thermostat failure, as it was not getting hot enough. I now live in eastern europe and winters are very cold so I end up blocking all front grill, so that car get hot quick enough and stay that way. Now I dont see trouble and hope that it will stay that way.@@hadiamrane
My Zafira only did 6000 miles a year. Used to go to work up a steepish hill to get it to temperature, 5 - 10 minutes on the motorway and it did a regen one day each week normally. I think the trick was it had to be at temp, given a bit of load and not turned off when it was trying to regen. It would regen on my alternate route through town sometimes which showed up as slightly high idle and noisy engine rattle but still did the regen ok and I never had an issue with it. My friends didn't do the motorway journey and only drove through town about 5 miles and they had issues, but their engines only just got up to temperature at the very end of their journey. I bought a plug in diagnostic to be able to force regens as required and never used it!
@@fastdamo Yes, temperature is the important thing. The ECU will also see how much soot there is in the DPF and sometimes will not do a regen. It's not because it's gets to a high temperature, that a regen will kick in. What I think that is happening to these cars that Jimmy gets is that they are used for such very short journeys that the car doesn't even get time to force a regen even if the temps are only 300 degrees. So after some time, the ECU has had enough of the suffering and limp mode kicks in and you get a message becasue the pressure if way to high. If only these people were to drive at least on some back roads with some hills, at least once a week then there will never be a message as the car will not do a normal regen but a forced one at lower temps. You will feel it going to higher RPM, the sound changing a bit of the car. If you drive on the moterway, of course you will not feel a difference as the car does a regen at higher temps where you don't feel it, but at lower temps you will feel as it forces it. But with these people coming to jimmy, there is no such time for the ECU to figure it out.
@@RawbLV So I've touch wood not had any hassle. My Indy said an hour's trip/motorway at least weekly you will be fine. A good fast run in France it ran noticeably Bett
Jimmy, i assume it would be best to do oil change after the Regen or DPF clean??? Also, i have a Zafira B 1.7cdti and have NOT SEEN ONE on your channel, even though i know its a very popular car in Europe. Is this because DPF issues are less for some reason?
