Set of 5 250ml Liqui Moly Diesel Particulate Filter / DPF Protector

Seams to help with DPF problem, definitely works

Good price for 5 don’t know how good it is as preventative maintenance

Very good product

Works to clear DPF warning every few month if I have only been doing short journeys. Good value

Hard to get the cap off

Bit like taking a vitamin tablet that you think Is beneficial but you didn't feel any different for It. The product may have done something useful but I'll never know.

Does what it states

great product

Worked great for my 2007 Jeep Grand Cherokee 3.0 Diesel. The other thing is how responsive and excellent the vendor was in getting the product to me. Highly recommend both product and vendor. Excellent on both fronts.

HAD SOOT SENSOR CODE , AFTER USE OF THIS PRODUCT IT IS GONE

I was getting a check engine light in my 2014 BMW X5 35D. It would come on and stay on until I towed something heavy , or really worked the engine, or drove it aggressively. Then, after normal driving, it would come on again. The code had something to do with the DPF filter, but I could not reset it with the code reader I have. I thought I would try this product knowing about the company that makes it. Glad I did. I started by running the fuel to close to empty. I put in a can and filled with 13 gallons of fuel. After, I ran it back to a quarter tank . I put in another can and 13 more gallons of fuel. I ran the car normally and when it got down to 1/2 of a tank, the check engine light went out, and has not come back on since. It has been at least a month and no issues. This product is worth the money and I will always have 1 or 2 on hand if this happens again.

Works as advertised. Great German product

Did a great job. No more Faulty codes.
