I will replace the pipe to get it back to OEM set up.

I inspected the 'elephant' inlet pipe at the weekend and found 3 splits in it:

The first photo is the dump valve part which I'm fairly sure I split by overtightening when trying to solve the last problem, as GrahamL predicted!

The second is the oil recirc pipe:

The third one is has a Y pipe stuck in and goes to the EBV:

So I filled with Sugru / putty like solution to plug the holes and drove it this morning and it ran fine. So I am sourcing another pipe and will refit this weekend and hopefully be able to enjoy my Coupe again!!

Well I fitted a forge dump valve and replaced the elephants trunk inlet pipe to the turbo and it's still running like a bag of spanners.

Excuse my neighbour who was chatting to me. This was the only footage where it gave the idling and popping fault, all the other times it would run fine.

Any thoughts before I torch it?

Try what I suggested on the phone with the MAF and let me know how it runs, it's defiantly testing your Coupé passion atm.

The new intake pipe was definitely 100% OK? Did you fix the leak at the oil breather pipe as well?

If so, how does it idle with the airflow meter unplugged? Think I have a spare one I could send you to try.

Also try pulling the cam variator relay and see if it fixes the bad idle.

Don't listen to me, but could there be something foreign "in" the engine, e.g. dropped inside?

Graham
-The replacement intake pipe was ok, I inspected it thoroughly.

-I will test the idle with AFM unplugged, although when I tried to drive it with it unplugged it barely made it to the end of the street under its own steam.

-Where is the cam variator relay?

Joe I will try this over the weekend if it's not pissing it down.

Simon, I think it's unlikely, I've not had anything off in the last few years which would allow something to drop in.

Could a turbo on it's way out cause something like this or would it just smoke like there's no tomorrow?

Silver one at the brake fluid tank. I never really got to the bottom of it but I've had idle issues solved by pulling that relay... the cam variator is engaged at idle and off above idle until high revs, so maybe if the relay is failing and flicking on/off it could cause a bad idle.

It could still be the air leak at the oil breather system if you haven't replaced those pipes yet.

The beaded joiner came without a beaded section so I didn’t install them back into the breather system.

That is a difference as I rerouted the breather pipe so it points up as opposed to down where it was previously.

So I’ll:

Pull the ecu & check chip
Pull the cam variator and replug
Recite breather system when the new joiner arrives

Edit Reason: check chip

This probably won't be of any help but I took the ecu out of my car the other day, inspected what chip it had in and refitted it. Upon starting the car it ran like a banger, I hadn't touched anything in the engine either

Removed the ecu again and noticed a few green/scabby looking pins, sanded them down as best I could, sprayed some contact cleaner and refitted

Car ran perfectly again, might have been pure coincidence but worth a look

Cheers Adam. I've recently had the ECU out to check for another issue, will see if I reinstalled it correctly.

So this evening I:

Pulled the ecu & check chip
Pulled the cam variator and refitted
Lowered the breather pipe so it points straight down

Will test drive it tomorrow.

Ha!

This car may well be the end of me, if I don’t end it first...!

It’s odd on the 5 mikes to work all I got was a slight drop in revs at the lights right outside the building. Onthe way home I had a backfire after a mile, by the time I was near home it was back to low power and constant backfires.

It seems to be linked to the idle, that starts first then the backfires and loss of power?

Chris buy yourself a tin of aerosol brake cleaner and while it's idling spray around the throttle body/ICV and inlet sleeves under the fuel rail, brake cleaner will make it stall if it's drawing in air from where it shouldn't be so worth a try for £2.99.
