Wynn's Diesel Particulate Filter Cleaner - Cleans & Regenerates Blocked DPF Soot Filters - Reduces Soot Formation & Emissions - Compatible with Diesel & Hybrid Diesel up to B30-325ml

I do a lot of short trips in my Range Rover, and in the past, I’ve had a few problems with the diesel particulate filter (DPF) getting clogged. Since I started using Wynn’s DPF Cleaner once every three months—especially when filling up with supermarket fuel—I’ve noticed a big improvement.I now combine it with using premium diesel whenever possible, and I haven’t had a single issue with the DPF since making these changes. It’s simple to use, just add it when you fill up, and it gives me peace of mind knowing I’m actively protecting my engine.Highly recommend for anyone who does regular short journeys or has dealt with DPF problems before. It’s now a part of my car care routine and it really works.

I felt obligated to write a review for this product because I cannot believe that it actually worked! The particle filter light kept coming on with my BMW X6. I had tried taking it for a few long drives, as some people suggested, to unclog the DPF but to no avail. I then put in a bottle of Wynn’s DPF cleaner and topped up with £50 of fuel before going on a journey of around 60 miles on the motorway. After that trip, the light then disappeared and hasn’t come back on now in a few weeks of driving. I was worried that I would have to the replace the DPF, which I know can be an expensive job, so this product really is a God-send. Just to point out: when I put in a bottle of this product, I let the fuel in the car run right down before doing so. The fuel reserve light was basically on, and I literally only had around 10 miles of driving left in the tank. I think this is the best way to do it because the product then basically gets straight into the system, with minimal dilution. I cannot recommend this item highly enough. 5**Update*Ok, so this item did indeed get rid of the DPF light coming on but, after a few weeks, the light did come back on unfortunately. I then tried another couple of bottles of this item, but it did not resolve the issue this time. I then purchased the Veepeak OBD II Diagnostic Scan Tool, which plugs into your car. I also bought the BMW BimmerLink App. What these things enable you to do is basically clear the error codes on the DPF and then “force” a regen. You basically connect your phone to the OBD tool, and select DPF from the interface menu. You then need to request a DPF generation. After doing this, go back to the main interface and select Error Memory. When it loads up, then select Digital Diesel Electronics and clear all the error codes. Once you’ve done this, go back to main interface and select DPF and it should show up as YES under Regeneration Requested. Your car will basically not Regenerate itself unless you remove the error codes, so you must remove them to force a Regeneration. The interface may be a bit different, depending on which app you use, but they should all be pretty similar. You can purchase the Veepeak OBD II Diagnostic Scan Tool from Amazon. It’s a very handy device to have.

Bought mainly on other + reviews. Not that my van needed it but felt it was a good idea to add to the tank every 5000 miles. No noticeable improvement in performance, hopefully it has worked silently in the background.

Daughter's Nissan Qashqai dci went into limp mode and had a code for a blocked dpf. It had been running rough for a while. I cleared the codes but it went into limp mode as soon as she went over 2,000 revs.She'd just filled up with fuel so I put two bottles of Wynns dpf cleaner in it and drove gently for 10 miles then I gave it a good thrashing for 20 miles. It runs perfectly now and I've done 200 miles in it, no issues.I will put a bottle of this stuff in her tank once a month to keep the dpf clean.Highly recommended!

This product saved me a lot of hassle on my BMW 530d, had a dpf light pop up on the dashboard and tried various other products that didn’t work, I had read reviews on this product and thought i would give it a go, I added the mixture to a full tank of diesel and did a 100mile journey up the motorway, within the first 15 miles of driving the dpf light went out and i also noticed the engine running smoother and an increase in mpg i was getting out the car. I would definitely recommend this product to anyone having dpf issues.

I've had more DPF lights come on on my car, however I managed to clear it still within the city by stressing the revs over 2000rpm so in essence possibly this product has helped, but no way will it eliminate all of the soot that gets clogged in the dpf filter. I think it states to use every 3000miles, but I've probably only done less than 1000miles and the lights come on.

Brilliant! Poured into half tank of diesel and drove for half hour over 40mph on A41 and DPF problem solved.

Great product for diesel engines
