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 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.

I used Wynn's Diesel Particulate Filter Cleaner and it worked really well. It helped clean out my blocked DPF and reduced the warning light on my dashboard. The engine runs smoother now, and there's less smoke from the exhaust. Easy to use—just pour it into the fuel tank. Great product for diesel and hybrid diesel cars.

When the engine light came on in my BMW 320d, my first port of call was to buy a basic ODB2 reader and found that the source of the issue was possibly the NOX sensor. As I was not 100% sure, I generalised it to being a fault somewhere in the exhaust system and thought I would give this a go. In the meantime I booked in for a potential £750 repair bill. I put the DPF Cleaner into half a tank of the existing diesel and then topped up with premium diesel. I emptied the tank on moderate runs to no effect. I then topped up again with premium fuel from BP and did quite a intense journey up North for a holiday and up some steep hills (low speed, high revs). The engine light cleared just 2 days before the car was due to go in! I can only assume that the combination of Wynn's DPF cleaner and premium fuel cleaned the system enough to rectify the issue, potentially saving me a lot of money!

I received my package with the Wynns in. Excellent stuff. Will keep on using this item

My EML was on for days stating Trap Bank 1 fault. Had it forced regen where EML went off for a few hundern miles. Came back on after a week. Was planning on having it's flushed at my local garage until I stumbled across a forum about this product. Long story short put it in drove for 30 mins on the M'Way still didn't do anything lighy stayed on. Few days later of driving with rpm between 2-4 the light went off 1 morning. 👍 I have used other products like RedEx to no avail. This is amazing! Saved me money. Was only £9. If you do have dpf fault on get this to help. I have a 2016 Audi a6. Have it in M mode and keep revs high and give time for the Wynns to get through the system. Long review but after trying things myself I couldn't find any help on the reviews so hopefully this helps anyone else with the same issue I had.

Bought this to try and cure a DPF issue with my car. Easy to pour into your tank due to the long necked bottle and filled up the car with diesel at the same time. Ran the whole tank and didn't clear the problem. I have read that some reviewers have needed 2 bottles to do the job but I had the DPF professionally cleaned in the end as I was getting concerned about running the car in limp mode for too long.

I put this into my girlfriends qashqai because hers was always under powered and thirsty for diesel in comparison to my qashqai with the same engine. After 10 mins of driving I noticed performance had suddenly gotten very lively and at the end of a few days driving the average mpg went from 37mpg to 44. We were never able to get it over 40 before.

I've used this twice now, we have a diesel but rarely do long journeys so DPF clogging is inevitable, both times we've done a decent trip after using this, cleared the warning manually and it hasn't come back whereas trying to clear the code before it just instantly came back every time you started the car.

Lo puse tardo como una semana en combinar bien con el diésel, lo lleve media hora a carretera y listo.

En principio parece que funciona. Recomiendo con un depósito casi o entero añadir el bote entero y cuando el vehículo tenga la temperatura circular a unas 3000 rpm e incluso apurar hasta las 4000 rpm. Lo he realizado así y de momento se ha borrado el código de error y el vehículo a recuperado toda su potencia.

Fonctionne très bien je le recommande

Ogni tanto sulla mia AUDI Q3 mi si accende la spia arancione avaria motore che indica secondo diagnosi gruppo farfallato sporco o filtro antiparticolato. Ho scoperto questo prodotto e l’ho utilizzato più volte, risolvendo il problema. Il mio è un 2.0 Diesel e utilizzo questo prodotto ogni 4000 Km specialmente se so di far lunghe percorrenze. NOTE: Quando si è a riserva al distributore inserire il prodotto e poi far il pieno o almeno fare 40lt , e cercate di fare lunghe percorrenze. A me dà ottimi risultati CONSIGLIO

Best DFP cleaner I have found
