Nissan NV300 13 Dealership Repairs But Fault Returns Same Day 253F29 Oil Dilution 200291 DPF 200292 

I'm just gobsmacked that even main dealers don't seem to know what they are doing with their own products !! Hats off to Jimmy the DPF King !!

All those forced regens done melted it

A chap who clearly knows his figures. 👍👍

It's incredible the incompetence of certain car repair shops who change a lot of parts except the one needed. Lack of skills, training? In any case, when a component has been changed and the problem returns, you must investigate carefully and be very professional, otherwise things will not progress. I've been watching your videos for some time now and they are very informative. Thank you for sharing all the work you do.

Great video.. i work for a few places doing diagnostic work . And they really should have their own mechanics trained better than what they are . The problem is fitters and mechanics are completely different people and most dealers have fitters , great for servicing and changing parts but no good for lets say stripping a gearbox and repairing it . DPFs are a pain in the arse unless you know what your doing... same with adblue faults and the garage will say 2 grand to get rid of you or cover themselves but most of the time your better of having a remap as the adblue tanks could be the same price you could sell the car for. Diagnosed a peugeot not so long ago been to 3 garages dpf kept getting blocked had about 400 spent on it ... turned out to be thermostat housing needed to be replaced took 20 min drive in it to see it wasn't reaching temperature so it wouldn't regenerate. when i trained as a mechanic i was taught if the car won't start.. check if there is any fuel in the tank 🤣

this would be the perfect example of the borescope video probe showing damage to the DPF's honeycomb.

As a Diesel Mechanic Dealing with this stuff Daily Im not Sure why The dealers were that incompetent. Mind Boggling. Knowing the Pressures and Temperatures the DPF Operates on a Product you work on daily should be Extremely Basic Knowledge.

yes then the dpf whisperer 👍🎅🏽👍

Car garages are getting worse! Well done mate really enjoy watching your videos! I own a vauxhall vivaro 2016 worse choice of me life had it 7, had a head ake ever since i drove off the forecourt from new they are shite

So, the dealers are reluctant to change the dpf under warranty due to cost? Ford have been the same with my transit courier. Surely their mechanics can read the dpf pressure? The constant failed regens cause oil level to rise with diesel, hence having to change oil every other week. Exactly the same symptoms on mine. After over a year of dealership visits and arguments in the office, they call in an independent who advises the dpf be changed (might even have been you!). Now waiting for over month as apparently transit courier 19 plate dpf is back order item. They even had the cheek to tell me it was my fault for not doing long enough journeys - isn't that defective design instead? Cheers

I have a 191 Nissan Nv300. Bought new from Navan Nissan. After about 3 months lights Came on for Dpf. They took it in and did a regeneration which lasted about 2 weeks. Back in again another regeneration..told they put new codes in and that should be end of trouble.. after about a year of going in and out they decided to replace the dpf which they did.They told me I'd have no more trouble... A few weeks after I could smell smoke in the cab.. I took it into Nissan again.I said the engine is going it's burning oil I was putting over 5 litres of oil a week. They didn't believe me. Eventually I said I'll bring it in and ye can dip it and see how much it's using. THEY had to replace engine at on 78000Km. After about a week engine mgt lights on.. They did dpf regeneration and again I'd say once a week for almost 8 months. I rang Nissan Ireland and was told that it was my style of driving that was causing my problems. And that Nissan would continue to support me.. I said great put me down for two engines and a couple of DPFS. I can now confirm that the engine that was replaced in June of 2021 has now blown up. Please stay away from any Nissan Nv300 guys. .nothing but a pile of scrap.. I've spent more time under it than I was in it..

Nissan dealer 'mechanic' just throw a parts cannon at the vehicle, and hope for the best outcome. Clearly lousy training, if any given. Bloody good job it's under warranty. As always, Jimmy great video and knowledge. 👍

sure some will have said this but oil dilution code will always set after static regen on this platform

13 oil changes in 12 months, lots of new parts and it's still broken wow the main dealer needs to train up their mechanics 😢

main dealer = parts cannon what a joke.

Now Nissan get the chance to show customers and others they're loyal to the warranty and will fix the problem and also accept they made a mistake and let's hope it wasn't a change something cheap and hope the warranty runs out job. I don't think they did that, I think they just didn't know how to test the DPF like the main man ( YOU ) and just did the regeneration and messed it up and they didn't know they messed it up. You should go and talk the managers and offer your testing and cleaning service to save them thousands of pounds or hundreds of thousands over time in DPF's and parts they didn't have to use. It's clear the garages don't have a clue so step in and help them I would. Might even do to myself knowing how bad they are at DPF work.

how many miles has it done

I'm gobsmacked that if it's under warranty why didn't the owner insist on a new dpf!!! Ffs!@!

Why surprised that its not the Mirrors temp sensor fault

Bout £2000 for a Dpf 😢😢 joke or what !

Are some of these DPF problems down to the diesel being watered down with bio fuel???? Using Shell I have had no DPF problems.
