Octavia 3 2l 150bhp diesel

I've had the car from 2016, almost new.

 

Anyone recommend getting a dpf clean done professionally to clean the filter more thoroughly than the car can do itself, or is this simply a waste of £ ?

 

A neighbour had a mobile dpf cleaning company come out to clean his Audi dpf - one pressure sensor was holed due to blockage. 

 

They cleaned the DPF on the car, so the catalyst downstream got all the run off of cleaning chemicals.

 

Would you recommend this practice of not removing dpf from the car to clean?

 

I'm using fuel additives and premium fuel which helps but the dpf still regenerates sooner than it did when I got the car, no errors. 

 

Thanks

Well, I recommend talking to local taxi drivers about who might do a DPFectomy...

As you allude to I would be taking it off to clean it.  However, unless the car was high mileage (120k+) I would be considering my need for a DPF equipped car.  If your regens are too often then you either have a high mileage hero and it's simply coming to the life of the DPF or you are not doing enough of the correct type of driving.  I'm an advocate of using good fuel to prolong the life of the engine and associated parts but there comes a limit to where you need to switch to a better solution.

Has anyone taken the DPF off car and cleaned it? DIY? Anyone care to share their experience?

I've heard a company takes dpf off, but this same neighbour's mercedes got a blocked dpf from euro5 engine. Dpf company said that they 'removed' dpf to clean , but it looks like it wasn't and it was cleaned on the car. 6 weeks later it was blocked again. New dpf fitted £1k 

 

Dpf was probably blocked anyway.

Found this...

 

 

 

It's a Superb, but the same EA288 engine.

 

Looks like coolant drained, steering arm disconnected, driveshaft driver's side removed, air hose, airbox. Not an easy job.

 

Anyone got this dpf out from above the engine bay without resorting to removing , disconnecting other bits?

 

Reading around - Cleaning advised off car with backflush because of contamination of CAT, lambda, dpf sensors, not full clean of dpf possible in situ, turbo might be damaged on exhaust side, egr.

 

Cleaning off car - dpf is flushed with warm water after soak in dpf cleaner, dried with hot air. I can't see that this is possible whilst on the car like these dpf cleaning firms are doing?
