Yes, that was the first thing done by a garage, and cost me £60 :(.

Also when it won't start, what exactly is happening? Just turning over, spluttering, misfiring etc

It turning over for 5-10 seconds, then misfires badly and slooowly starts, revs literally increase from 0 to 2 within 5 seconds, then no more misfires. Not like when engine is cold and it starts straight away to 1.5k revs.

So when it is hot it starts then sits at 2500? How long does it stay there for?

And when cold how long does it sit and 1500?

Few seconds, and slowly moves to 0.8 revs.
What I'm thinking is: what if I will do the paper clip test and take a video of eml light blinking? Also, is it ok to do paper clip when I drive?

Hmm trying to wonder what it could be that's why I've asked the questions.

Unsure if you can connect a scanner or do paper clip as you drive, never had a need to try. Besides you would need about four hands haha.

Does the car use water or oil?

Nope. Checked today.
When the engine is cold it starts as a new car. But when its warm, its a nightmare :(

Long shot, any damage to the wiring loom?

If the connection for the cts for example was bad it would cause a similar problem as if the cts itself was f**k

Coolant temp sensor.

Only other idea I have for now is an immobiliser problem.

I changed CTS, no difference other than now fan kicks in nearly at 100. With old CTS it was kicking in at around 95-96.

I saw that that's why I suggested the wiring loom.

Really am stumped for ideas other than wiring, immobiliser or ignition

Try a second hand coil pack

I bought a second hand coil pack with leads. And no difference. Problem is still there. Car poorely starts when its warm.
I've done paperclip test. Found these 2 faults:
1405 Exhaust Gas Re-circulation (EGR) valve n/a
0115 Intake Coolant Temperature Sesnor (CTS) n/a
I blanked my egr about 2 weeks ago, (car is not jerking anymore). can that be the reason of this fault?
And CTS was replaced about a month ago.
Any suggestions?
