DPF Cleaner (for Diesel Particulate Filters) Made in Germany for Preventive Maintenance of diesel exhaust and emissions systems

2012 Audi A3 TDI Sport Wagon... DPF (Diesel Particulate Filter ) Error Code along with the Check Engine Light. Removing & Cleaning a DPF costs a little over $1K... Replacing it outright is almost $2.5K... This is $30 per can DELIVERED and it is NOT instantaneous... BUT IT WORKS!!! I put it in with 12 Gallons of Diesel. My research revealed that short hops and low-speed stop & go driving generate excessively large carbon and hydrocarbon particles that can overwhelm & clog the DPF. The key is to Get The Diesel Catalytic Converter and the DPF REALLY HOT so the Self Cleaning/Regeneration feature of the DPF can function. This Additive Supports Those Functions. So, I ran through the tank of fuel in Sport Mode and took a couple of 1+ Hour Trips on the Freeway up into the mountains and out on the flats. The Error Code Disappeared as I neared the end of the tank of fuel. Just for good measure, I am going to run another can through the system. Gambling on chemicals ($60) plus a couple of tanks of fuel ($70) and a few hours of my time enjoying traveling to some really nice destinations & back is easily worth not having to spend $1,000 to $2,500! Plus the Audi A3 TDI Sport Wagon is a Blast to drive... Especially so when you are trying to get it HOT! ;-)

I had been told by my car guy that replacing my diesel particulate filter could cost $3,500. There's no way I was going to invest that much money into my BMW X5 again! I looked around, I did a bunch of research & found this product. The reviews were consistently good. So many people had successfully used this product & I couldn't pass it up. One or two cans might have done the job but I ended up using three. Way cheaper than $3,500, regardless. And it worked! I still have the check engine light on but the diesel particulate filter issue no longer shows up when checking codes. Since buying my car I have learned so much, especially about diesel vehicles, & this was one more aspect of that education! I'm so glad I found this product & I bow to the makers of it! Thank you!

So for me I’m only giving it 3 stars because it didn’t take my light out, I see it worked for other people though so don’t let my review lead you away from buying it especially since the price isn’t bad. I did smell the horrible smell you are suppose to smell while the product is helping burn the soot away but it didn’t burn it all I’m guessing. If you have the same issue I did I recommend you buy an OBD2 that supports the DPF function so that you can get rid of the code, that’s what I did. It cost about 90.00 for the specific one that supports it so trying the cleaner first might work for you and it’s worth the try but for me it wasn’t a fix so the cleaner isn’t a definite fix.

Good product for the money

Had a check engine light on pickup come on for DPF. This cleared it after 50 miles, add a can every other tank of deisel and no more chech engine lights for this.

Does nothing to clean the dpf filter, ran it on a full tank as the instructions say, waste of time and money

If u have an audi diesel and the emissions light keeps coming on and ur cheap like us buy this don't bother with thr dealship

My truck has had emissions codes off and on for years and decided to try this product. I put 2 bottles in a full tank (Ram 2500) and drove on the highway for a road trip. When accelerating with the turbo boosting, I noticed through the side view mirror that the DPF deposits were coming out of the tailpipe. This continued until the tank was 1/4 full. Since using this product, my emissions codes have disappeared, power has returned, and I live my truck again. I will be using again in the future!
