29079 DPF & GPF On-Car Cleaner 500ml

This was very effective done what i need to be done. I previously purchased a different product by JML and used it on my blocked DPF which had accumulated about 38g of soot. This worked great after leaving it in for about 30 mins and got soot content down to 17g. However car was still wanting to do a regen. A week later i purchased this product mainly because it was one of two options to get it next day delivery. I put it in the dpf and let it soak for about 2 hours this time. took car for a drive and within minutes I had the white ash/smoke out of exhaust cleaning the system. After about 30 mins of driving, regen was complete and soot content down to 5.6g. Perfect! This may have been just as good as the other product I purchased, but i think because of the amount of soot that had built up, leaving for longer to soak really helped. I will defiantly buy again if I need to use it. Yes you can smell it as its burning off the soot, and you get strange looks from people as your driving, but it was only maybe 4-5 mins of thick white smoke which is good as you know its working. We have had the car for 5 years and its never done a regen in that time. I now know that someone had turned of the automatic regen on the car, which is what has led to the accumulation of soot build up in dpf. If regen was turned on then we probably would have never needed to purchase this product in the first place. Its quite costly especially when you have had to do it twice. But for now I am happy with the results.

My Audi A4 3.0 TDI (crtc engine code) was in limp mode with blocked DPF caused by faulty EGR valve, now replaced - so had 'drive fault' warnings on start up, cruise control inoperative, no performance. I have the vag-com / vcds cable and software so could see two fault codes, 5188 - particle filter excessive soot - and 5189 - particulate filter bank 1 efficiency below threshold. I warmed the car to normal temperature, removed one of the sensors in the 'upstream' / turbo end of the DPF after soaking it for a few days, then used the whole can of cleaner, spraying into every part of the filter that I could using the long hose supplied - obviously avoid any fumes / wear a proper filter mask. I followed the instructions to let it soak for 30 mins, then started it, let it idle then run at 2,000 RPM then test drive. Initially, no foam came out of the exhaust, unlike in the You Tube video, and at first it seemed to have had no effect. But on the test drive, still in limp mode, grey/black smoke started to come out of the exhaust, for about 15 minutes. When I got back, I cleared the codes, and the car was back to running properly; no warning lights, no limp mode, if anything it felt better than before. I checked the regeneration data and it had just done a 'passive' regeneration on the drive, which it won't do if the fault codes are showing. I was stunned; I was quoted £264 for an on-car clean, this seems to have fixed it for less than £25. Fabulous.

Bear with me as this may be slightly technical. Car is a Seat Leon MK3 2.0 FR, 137k miles. Car is mainly driving round town, school runs and food shops, occasionally runs on the motorway, which is not great for a diesel. Oil ash reading is showing around 50grams (60-70% full). DPF pressure showing around 20-30mbar at idle, and under load it’s showing between 80-220mbar, which is fairly high because of the ash load (blockage). Now, I’ve already used x2 other branded dpf cleaners from GSF car parts before, within the last month. I bought this particular wynns brand as the description shows it would clear soot and ash. My biggest issue (safety) with this product was that the description shows the car needs to be up to temperature, then you send the cleaner in. Now, as I did this after the car was at running temp, the cleaner spray started steaming and soot spitting out of the exhaust gas temp sender straight into my face on the first blast. !!!Wear eye protection!!!! I watched the exhaust temps and they were on 200c. So, I would recommend you wait until temps are under 150 unless your happy with steamy soot flying everywhere. Back to the performance of this. It definitely clears soot, but I wouldn’t say it clears ash very well. My Pressure sensor was showing between 25-30 pre clean, showing same pressure after the clean. Pressure was confirmed with a manual manometer. I guess if your issue is mainly soot, and not ash, then these on car cleaners should work as intended, but if the issue is oil ash, then I suppose it’s best having the DPF taken off and cleaned via reverse flow.

Seem to have received a dud can,as it has only dispersed 50% of the can before it stopped coming out. So has done very little in cleaning dpf

Brilliant cleaner used on a bmw 335d with dpf light coming on every journey. Left it for 30 mins to soak, started it up and left it idling for 20mins. Loads of dirty black bubbles from the exhaust then took it out for a fast run, accelerated onto a motorway and left a cloud of grey sooty smoke behind me. Rechecked the fault codes for dpf and cleared them, been driving it for 2 weeks now with no fault codes and a smoother running car, very pleased with Wynns dpf cleaner highly recommended.

A lot cheaper than paying to have the dpf removed and cleaned. My dpf was blocked badly i put this in left it for 5 minutes then went for a 20 min drive it didn't work until I took the car out the next day for a longer drive then a big cloud of smoke came out and the car had full power again I have my own fault code reader and reset the engine light myself now the car is running perfectly again

Possibly the only dpf cleaner on the market that actually works. Dropped dpf by over 20%. Enough to take limp mode off VWs.

Had an error code on my BMW 520d for the DPF filter, after a quick youtube tutorial decided to give the foam cleaner option a try. This stuff was excellent!! Very straightforward just shake and squirt, leave for 15 mins then go on a 30 minute run. Took the exhaust back pressure from 78 millibar at idle to under 10. Car runs amazing and MPG increased back to 45+mpg from 30 with a blocked DPF. Highly recommended A+++

Même si cela demande une légère connaissance pour situer un site d’injection adapté Une fois utilisé en respectant les modalités d’utilisations, wouaouw !!!!!! Ça nettoie Bon on se demande si le FAP est vraiment un objet de dépollution finalement, car il retient tout et grâce à se produit tout ressort Plus de voyant et plus de perte de puissance moteur

Perfecto.

Ottimo prodotto per risolvere i problemi di Fap/DPF intasato. Posso assicurare che è molto semplice da usare, si smonta la sonda Temperatura e pressione posta in mezzo al DPF, si inserisce la cannuccia e si svuota dentro la bomboletta per tutto il suo contenuto (spruzzando diventa schiumosa e qualche parte di schiuma uscirà dal foro dove stiamo spruzzando) va applicata a motore freddo, poi una volta spruzzato dentro, lasciare agire per almeno 30 minuti (io solitamente lascio Agire per 60 minuti) passato il tempo di "riposo", bisogna lasciare girare il motore al minimo per 5 minuti, poi altri 5 minuti a 2000 giri, successivamente 60 secondi al minimo. resettare tutti gli errori in ECU e fare un giro in strada di almeno 20 minuti. ATTENZIONE!!, per il primo chilometro e mezzo l'auto fumerà parecchio, vi sembrerà di essere sulla macchina di 007 quando attiva il fumogeno. L'ideale è andare su una strada poco trafficata onde evitare maledizioni da parte di chi è dietro di voi. una volta fatta tutta la procedura l'auto sarà libera come prima di essere stata con il dpf intasato. solitamente il giorno dopo l'auto effettua una rigenerazione naturale.
