Engine suddenlly started losing perfomance, hesitating not running smoothly. I connected obd tester and found that DPF or FAP filter was jammed.
I checked my options on a web and found out that the cheapest way is to try with cleaner in a can. All other options are professional and require spray guns and other tools.
I bought CARTECHNIC DIESEL PARTICULATE FILTER CLEANER for 13 euros, which is cheaper than wurth DPF cleaner. You can buy it from Stahlgruber.
Here are specs of cleaner:
- For all closed diesel particulate filter systems
- Raises excellent carbon and ash deposits in diesel particulate filters
- Neutral rinsing members ensure smooth removal of soot particles
- Not flammable
- Neutral and ash / metal free formulation
- Cleaning without disassembly of the diesel particulate filter possible
- Evaporates without residues
Applications:
- To restore the full capacity of the diesel particulate filter
- When performance degradation or interference from dirty diesel particulate filter
- For prevention in unfavorable driving profil
Lift your car up and locate dpf filter under your car:
Than stick hose in hole and pointed in direction of your dpf and slowlly move it while spraying. Then screw sensor back and wait for aprox 15 min. Erase all faults on your engine computer and make sure your fuel tank is at least half full.
On some cars you can force dpf regeneration with obd tester when car is heated.
Startup your car and you will immediatlly see smoke from exhaust and don’t turn it off. Smoke is sign that the ashes and carbon deposits are removed from dpf filter. Go for half hour drive, your car can smoke up to 15 min. You can also start regeneration from obd tester.
I must say that after the cleaning car is much more powerfull and throtle response is much better. I’m very pleased. I might buy another can, because in manual is that if DPF is very dirty you will need 2 cans.
