Audi A4 2.0 170HP Dpf off problem

**Jashmine1983** · 3rd June, 2015, 03:42 PM

Hy to all!
I did a dpf off on Audi A4 (year 2006 PPD1.3 2.0 170HP) but the car is working the same... no power until I reach 3000RPM and a lot a smoke.
Before DPF OFF I did a regeneration.
Guessing is not a good map.
Please help with a good solution for dpf off and egr off for this car.
Thanks!

PS: I've attached the original and dpf OFF file.

what DTC's did you have before DPF off ?

is DPF empty ? have you tried a road test with original after making a reset ?

I've psihicaly removed the DPF... I didn't try a road test before removing... The DTC sounded like "Particle filter below threshold". I didn't had any other error. Now I don;t have DTC's but the car works the same.
I don't understand why the car has no power until 3000 RPM. This problem was before I've switched off the DPF from flash.

i mean have you tried the car after physical remove DPF and after reset DPF values ?

does it have same behavior that after writing mod file ?

The history off the car..I've bought the car mapped already. I was on a service and they writted the original file back on car. I don;t know why.... after that the problems appeared... no power until 3000 rpm... particle filter DTC... I'm guessing the car had EGR and DPF off when I bought It. I need an modified file with a good DPF and EGR off.
The car behaves the same after I write the the mod file. The only difference is that that the particle filter DTC does not appear anymore.

If i write the original file from another ECU could be an IMMO problem?

**Jashmine1983** · 3rd June, 2015, 05:31 PM

I've writed another file, from another car, but no communication to ECU.
I've writted back my file with DPF off, the car starts but I don;t have power on car until I reach 3000 RPM.
Maybe is something wrong with the file.
I don;t have any other idea.
Please help.

Does not work. It stops at 2% when trying to write the file. I've tried with mpps and fgtech.
My file works, is writing good.
Soo... still have the problem with DPF off and 3000RPM limit.

TeamTuner sais that is a checksum problem with my interface. Can somebody help me with a good dpf off solution for this car, checked?
To write this car a have mpps and fgtech.
Thanks!

try and write file with mpps in slow, recovery mode

**Jashmine1983** · 9th June, 2015, 03:31 AM

Thanks! I could write the file but.... still no power until 3000 RPM.
With this file I don't have the same torque after 300RPM as my file.
I don't have any dtc. The particle filter status is OK. I've removed the jack from pressure sensor.
Still don't know why the car does nor accelerates until 3000 rpm and loss of power after 3000 with this map.
When the RPM is under 3000 ad I want to move the care, sometimes the engine cuts off.
