Replace your spark plugs, and coil-packs if you have them.
Mechanics told me I needed major engine work as that was causing the misfire reading on the diagnostics, but I replaced spark plugs (which were only a year old) with new factory ones at just £10 for 4 (not special over-priced ones like I had before) and now no misfiring and better fuel economy too.

Fault in emission administration equipment. The accepted emission limits may be exceeded. seek for advice from a workshop. - potential precisely WHAT IT SAYS, there'll be a hardship code saved interior the motor vehicle which a sturdy storage can examine with a diagnostic device Does this propose my catalytic converter is on its way out? if so is that gonna value me around £a hundred and fifty-2 hundred to tackle? -NO IT does not propose THAT in any respect. it particularly is merely considered one of the numerous possibilities which in actuality might value greater advantageous than £2 hundred. till it is going to be clinically determined you will in no way be attentive to the reason or value.

when was it serviced? blocked oil & air filters will have that effect and should be replaced with the oil & filter when serviced every 7000odd miles in an small diesel. also a cam sensor fault will have that effect if it has one. do you use biofuels or regualr diesel in the car? if you're running on the chip oil (like me) a tank of diesel and a new fuel filter does the job every time, i change my filters every 4000 miles when running on veggie.

replace diesel filter and put some injector cleaner in with the diesel.good luck.
P.S. diesel ignites under compression it does not need a spark, the glow plugs that it does have merely warm the cylinder to aid combustion.

Sounds like you could have a turbo problem or air leaking into the fuel system.
A big thumbs down to the idiots who think diesel engines have spark plugs!

There are so many variables to that , have a compression test and have the injectors tested ,

Hi
This sounds like a problem with the cam shaft sensor, what year is the car?
Cheers

Faulty injectors, plugged air filter, fouled spark plug, bad spark plug wires, vacuum leak, low compression, blown head gasket, .......
I could list 20 more things.
Take it to a reputable shop.
