@J.R. The DPF cleaning posts related to my other old Yeti with the hateful CAYC TDI, I gambled on 5 litres of off-car DPF cleaning fluid being cheaper than an off car full clean, this car has never been used for short journeys and I want to stop the problem before it gets that bad.

 

Unfortunately for this thread I sold that car earlier this year, but I can report that after a few treatments the differential pressure figures came down noticeably. 

 

 

Off car meaning you removed the DPF?

Is that easy, hard? I appreciate I have a different engine code.

Does off car cleaning require special tools or just a brush, pressure washer etc?

The video I watched looked like similar fluid injected into the flexible tube to the pre DPF port, it looked like a pressurised pot airline jobby, maybe a pressurised weedkiller or parafin blowlamp could be used.

 

I'm just looking for guidance on what others have done, its heartening to hear it gave noticeable results.

The cleaning fluid is meant to be used with the DPF removed, it's this stuff;

I poured half a litre through the top sensor hole on 2 occasions, left it there for 3 hours then took the car for a blast for 20 minutes holding the engine to the red line as much as traffic would allow. 

 

Afterwards the diff pressure figures were generally lower and it seemed to me to rev slightly better, but as I've said before I sold the car at this point so can't say what happened afterwards ... but we still see the car in the area, so I didn't kill it !

 

 

Thanks, it wont show me a price as they do not deliver it to France, could you let me know how much it is for info, I could get someone to bring some over.

 

Did it smell like anything special or just an industrial cleaning fluid?

Can't say I was that keen to stick my beak in the top and take a deep breath if I'm honest ...

 

Cost in UK is usually around £25-£35 depending where you buy, I then decanted to a pump up type sprayer - I did the job in 0.5 litre at a time as I had no idea what would happen !

I have the Erwin manual for your engine code if you want to see

Yes please, the pressure drop across my DPF is too high and I will have to do something about it.

So glad I switched back to petrol power 

 

Mind you no GDI car is going to be too happy with 1 mile trips either

You said it - lots of fsi engine pitfalls ...
