Bought the Citroen last week, drove it home at 100 kph no problems .
next day decided to bring her on the autobahn and got her up to 153 kph and she sat down on power and error messages sprang up about engine management (in german). at the same time the low petrol message came on .

went home got my diagnostics out and got 3 messages 2 saying misfire on cylinder 2 and 1 saying misfire possible because of low fuel.

so step 1 i filled up the fuel. still no power still cylinder 2 misfire.
step 2, replaced with new all the plugs and found 1 plug was black.

looking for next step advice, thank you.

Usual suspect on these is the coil pack if it's a petrol engine,
which you didn't state.
Or if diesel possibly an injector fault.

Coil pack usually the favourite .

replaced with new coil pack. (120€)

still getting misfire. i think the next step is to switch around the injector cables and see if the problem switches to a different cylinder.

i wont do this until someone says its an option

im reaching the end of my knowledge on this will check the injectors and test them. i dont know anything about compressions.

if its not the injectors. i will just have to bring it to a mechanic

well switching the wires is a bad idea but moving the injectors isn't.
Swap injector #3 with #2 clear codes and run it.
Retest it to see if the fault code has moved cylinders.
if it has you have a faulty injector.

ok i was away for a day,

came back and managed to test the injectors all are testing ok with an ohms tester set to 200 all are testing at 11.5/8

im wondering how to get the damn things out so i can switch them around they are on a rail below what looks like part of the air box

this is the image the top of the piture has the airbox bit thats covering the injectors, i cant find any images online or blow up diagrams showing bolts and such. later ill have access to a ramp so i can get under and behind the engine.

i cant wait till i complete this so i can update and show what was wrong and how it was fixed haha

you need to get the inlet manifold off to gain access to the injectors

yeah. took a few weeks and alot more money than i had but it is fixed,

after checking everything above and got the injectors out.

injector 2 was not working correctly because it was physically damaged. (alarm bells)

checked the cylinder head with a camera and noticed cylinder 2 was wet with moister. (alarm bells getting louder) hummed and haa'd and took the head off.

exhaust valve was melted. (alarm bell was chucked out a window and smashed)

so gaskets, oil, coolant, vavles, sealant, injector, tools. nm ratchet and a haynes manual.

winter tyres and wheels because i now live in germany.

and when i was looking into the engine bay i was humming and hawing about looking at the alternator...... well I had to buy a new alternator.

so the guts of a 1000 € but i learned ALOT.
