No this isn't a thread about removing it ;)

Yesterday I popped along to see Ned at Autolusso to get some advice on a future purchase and while I was there he mentioned this new product he had for DPF's, it is a method for cleaning it.... and I mean REALLY cleaning it!
He asked if I wanted to do it to my brera, I said I wasn't that fussed as mine had just done a regen on the motorway about 80 miles ago and all seemed fine. But as we chatted some more and he was telling me more about the product I became more interested and in the end I decided to let him lose :D
So the car is taken up to temperature, the solution gets added to the DPF (not the fuel tank) and then a forced regen is started........ OH MY GOD, considering that the car had done a regen on the motorway without problem a short while ago I was amazed about what came out of the exhaust :eek: The builders working on the Morrisons across the way seemed amazed too :lol::lol:
The difference afterwards was quite a surprise, I guess it's like new! The car seems to pull much better and also idles smoother, but fuel economy also seemed to be slightly improved :confused: which was unexpected. I am sure there is a performance gain there, maybe the regular motorway regen isn't enough to completely clear the DPF... I don't know! But whatever it is I am glad I had it done!
So, there are quite a few of you that have had your DPF removed and had the car remapped and thats cool if thats what you want to do :thumbs:
But there are others, like myself, that have chosen to keep the car as standard through personal choice, some others who don't want to pay X amount of cash, some who worry about the extra torque going through the drivetrain, some that worry about future MOT legislations - to all of you I would whole heartedly recommend a visit to autolusso to have this treatment done to your DPF :thumbs:
For a cheap item it seems to make a big difference, and to physically see the crap that comes out of the exhaust is pretty impressive and make you feel like the couple of quid you have just spent was well worth every penny!

Dont worry about it, it only affects diesels.

Uhm... I think you got scammed. The 159/Brera use "dry" DPF, a sealed unit that "mechanically" burns all the soot and nasty build ups from time to time making use of the raised temperature in the exhaust. I don't know of any method of adding anything to the DPF without removing it as it's part of the exhaust system (and that is kinda impossible with the car running as the exhaust gets quite hot).

BMW, PSA, Mercedes, and many others use a different DPF system that requires an additive to function and they have a separate tank for that.

There was no scam :lol:
I witnessed it with my own eyes :)

Hopefully Ned will be along soon to give you the full lowdown on it.

Obviously I am fully aware of how the DPF and regens work :)

As I said I realise how a regen works!! I have seen more than enough of them before, there is smoke on both forced and natural regens, but thanks for the lesson ;) There will always be smoke when diesel is fired into something as hot as that! But this smoke - as mentioned above was far and beyond what usually occurs, especially when you take into account a regen had taken place within the last 80 miles of motorway driving!

I would rather leave it to Ned to tell you all the in's and outs of the process which I am sure he will do soon enough. :)

Hi all, right to be sceptical I was, we buy about a grand worth of stuff from Wurth a month, nuts and bolts, injector cleaner, rust off, 20-40, studs, washers, time sert, etc etc etc

When the rep came round and said "we now have a magic DPF fix do you want to buy some"

I said "how much"

He said "ÂŁ45 + VAT per can" :wow::wow:

"On your bike mate"

He gave me one to try and the pictures attached are of a 159 1.9 JTD that had real running issues

The can is emptied directly in to the DPF through the sensor at the front at normal running temperature, leave it for 10 - 20 minuets and carry out a re gen, smokes the street out and fixes the problem

The results are unbelievable, basically the DPF problem is sorted

I think it can't hurt to do it once a year, it has to save twice as much in fuel as it cost to do

We charge ÂŁ100 for this treatment and re gen and if you are not happy with the results we offer a money back guarantee

:eek: I guess I shouldn't have said a few quid!

To be honest I was unsure of the price because I was a bit of a gunnia pig :eek:

But the results were pretty amazing!

In order to use it you would have to be able to tell the ECU to do a forced regen - so you would need fiat ecu scan or similar. The DPF is located at the start of the exhaust system after the manifolds/downpipes. There are a couple of sensors on the DPF and the can is emptied into the front one (I believe its a pressure sensor and this helps the ECU to understand when the DPF is clogged and needs to regen).
I would say if you're unsure about doing it, then don't do it! The DPF is an expensive bit of kit to replace. Also if you do decide to do it yourself and do the forced regen do it well away from your home any anyone else, and be warned the regen can melt the tarmac due to the extreme temperatures generated!
If in doubt, I would suggest a trip to autolusso to let Ned do it for you, you will be surprised at what comes out of it, and best of all it can be done while you wait :thumbs:
