Hello all .

 

After some advice if I could .

I have a 1.6 tdi Fabia , CAYC engine code . I am having continuous regeneration issues , regardless of my driving style . I drive 30 miles a day to and from work , some motorway miles , so A roads ,and even if I take the car on a long drive , it still starts regenerating . On average its every 400 miles or so , which can be twice a month .

I have had a new egr fitted , pipes are clear and dpf is clear , someone has mentioned that it could be the injectors,  a friend has hooked the car up to ODiS and read the injector values,  but wasn't sure what the values meant . I have attached the file , could anyone advice me if this is good or bad .

 

Thanks 

I don't have any information for the picture you attached but at 30 miles a day, frequent regens is common especially if you're at high mileage. Mine probably wants to regen every week or so but without the DPF light. I do the same mileage as you, 15 miles to and then 15 miles from work but I have the previlege of opting for either motorway or country lanes. To ensure your DPF regens even before the light comes on make sure you drive in 4th gear above 2k RPM as much as you can, on the motorway 5th is fine as 70mph is around 2.1k RPM. Use the car like it has a 4 speed gearbox unless on the motorway.

 

You also need to ensure the car is warm, when regenerating even without the DPF light you'll see oil temp hitting 100 degrees even in the winter and it'll idle at 1k revs.

 

Try and pick a route where you'll be travelling at the highest speed when the car is hottest. For example on the way to work I have plenty of road to get the car hot before going on the motorway, but on the way back from work the car won't even be hot enough by the time I get off the motorway.

 

Hope this helps
