I bought my diesel car new, drove it to my garage and left it there. It has never given any problems and saved me a fortune in fuel, maintenance and insurance. I do have to cycle everywhere though !

my friend's father once said - if DPF error appear ...give a car to youngster, he will know what to do...

As a mechanic, the first thing I do when a dash light comes on in one of my cars is unplug the battery for 30 second and reconnect the terminal. That works pretty much every-time there’s no real fault. I had a car with the engine light and it was the o2 sensor. I unplugged the terminal and it would go away for a thousand miles and then come back on. I did that for a year

Part of the film is a petrol car. With spark plugs.

How about a ECU reset when it is fitted with an auto start stop feature?
Is there any difference to the process please?

Doesn't work!

If you disconnect the negative from the battery, first, why would it also be necessary to disconnect the positive?

Ffs if you blow the tyres up it will unclog your dpf clearly
And If you clean your windows it will never need a service 🤡🤪

Haha, this one trick takes 12 1/2 mins to explain. Don't think so... outta here. YouTubers get paid by the minute and I am fed up of hearing... "Stay to the very end for the most important part!" :face-red-droopy-eyes:

How come if this is about diesels there are so many pictures of spark plugs in gasoline engines. This immediately shows that the rest of the information they’re providing is suspect. I guess that is mostly AI, but I don’t trust their reasoning.

@StuartThorn-b9n 7 months ago

Well I did exactly the same thing and the car wouldn't start atall

AI vids are BS

@thebeerhunter7307 8 months ago

Absolute BS of hints, the reason for a diesel vehicle being 'sluggish' is because 90 % of them are city driven, if you want to regain lost power and performance, take your diesel vehicle on a drive that makes you engine 'hot' I mean long distance HOT, it burns the crud out of the engine, its as simple as that, been doing that for years with my diesel car, dont do what this muppet does, doesnt work !
