My local garage has offered me to remove the DPF honeycomb and only leave the sensors. They said there is a 50/50 chance that the MIL light comes on but they are not sure and they can’t guarantee me anything. So my question is: Has anyone tried to remove the DPF without software delete? Is that a good idea? Does it stop the annoying automatic regenerations? My Captiva is a 2007 2.0 Diesel. Thanks in advance!

There are numerous discussions on DPF which can be read by using the Forum Back Index Advance Search tool. [Go to three white dots top right of main header bar].
Typical post example here :- DPF removal review
It is unlikely that the DPF can be removed without remapping. It is a bit of a mine field topic.
Your vehicle testing may well be different to UK/Europe. In the UK the MOT test will be an automatic fail if it is identified that the DPF has been removed.

The testing in my country is passed after a visual check only so the removal will not be a problem for sure. I want to try without software delete because in the region I live there are no workshops that are able to do a remap. That’s why I want to be sure that I’m not going to have any problems when I do so. My main problems with the DPF are the frequent automatic regenerations causing high mpg and oil contamination.

"I want to be sure that I’m not going to have any problems when I do so."

I'm not sure that anyone on this Forum is going to be bold enough to give you the 'all clear' on that request.
There may well be suggestions but no guarantees.

Thanks for the instant and detailed replies! I will try doing it without software delete and if it doesn’t solve the problems I will find some place that can turn it off. I am going to provide updates as soon as the car is ready!

Strange because according to the official Bulgarian version:

WHAT IS INSPECTED DURING AN ANNUAL VEHICLE INSPECTION

During an AVI the overall condition of the vehicle is inspected, particularly the following:

- Vehicle identification (registration plates, documentation, VIN, etc.);

- Components of the braking system (functioning, condition, parking brake, ABS, etc.);

- Steering (mechanical condition, backlash, power steering, etc.);

- Driver visibility (field of vision, condition of windshields, mirrors, wipers, etc.);

- Lights, reflectors and electrical equipment (lights operation, gauges, taillights, turn signals, hazard lights, battery, etc.).

- Axles, wheels, tires and suspension (axles, condition of wheels, tires and suspension)

- Chassis and equipment related to the chassis (condition of the frame, cargo compartment, etc.).

- Other equipment (seat belts, fire extinguisher, first aid kit, horn, speedometer, etc.).

- Harmful environmental effects (noise, exhaust emissions, leaks)

The MIL will come on. The differential sensor is expecting to detect a certain pressure difference from before and after the DPF. With the empty 'box' you will have free flow, so no difference in before and after pressures, which is a system fail.
