I thought if you car runs out of fuel, it isn;t as easy as just putting more in?

thats with diesel.

 

[ScottHmk4]

hmmm maybe worth a try letting it run dry, i would be too anxious tho not knowing when it would knock out

 

[vroomtshh]

thats with diesel.

even in a diesel, you just fill it up and go again

 

[Aimez]

It's cough and splutter for a while it won't just cut out with no warning

 

[ScottHmk4]

Dude, I have never known anybody have as much bad luck as you mate I really feel for you! Sorry though, have no idea what the new problem is, i'm sure some clever bod on here will help!

Have you plugged it into VAGCOM? Not just for error codes, but to do some logging

only faults im gettin is intervention load management and something about motor flaps for the aircon, nothing unusual. i will be honest i dont know how to do logging. my brother is stumped, so am i!! think were gonna put the old injectors and coolent temp sensor back in, other ones didnt make a difference and came from a scrappies, so i dont trust them that much.

Logging is pretty straightforward and should show up some faults. I've no idea how to read the logs but plenty people on here can.

What is the intervention load management fault related to? Never heard of that before.
I'd say you can discount the aircon flap one.
Do you know anyone else with the same engine? Try swapping your injectors and temp sensor for theirs for a week?

 

[ScottHmk4]

how do i go about logging?

 

[vroomtshh]

COnnect everything up, and I'm just going from memory here - in the engine diagnostic section, theres an option to log. Down near the bottom left. You choose the blocks you want to log ( a quick search on here should tell you which ones), and then it does the logs, saves them and you post them on here to get opinions.

I think you probably want to log requested airflow against actual, and something to do with EGTs for your problem, but I'm sure someone can direct you better in that way

just went to do some logs, as it idles in the runway as i set up the logging the car started doing that drop of power, then very very violent shuddering, re-scanned the engine. misfire in cylinder 1. COILPACK AGAIN!!!! just replaced a coil last week in cylinder 3

Sounds like you have an electric issue of some kind... I would get it seen by an auto electrician,no way it should eat a coil pack that fast, there is something wrong there...
Was it a "new" coil pack you have put in?

Its a different cylinder, and from what I hear going through coilpacks like that is extremely common. They tell you not to replace them one at a time

we replaced coil 3 last time, this was coil 1, apparently common to go one after the other, lets hope 2 doesnt go soon, tht'll be anotherr £30

I've heard of people having spares in the car its so common.

 

[ScottHmk4]

lets hope its not that bad lol

 

[ScottHmk4]

so heres what it was doing, i.e. a 1.2 3 cylinder running on 2 cylinders.

1) At least your tunes still work!
2) It's really giving those engine mounts a good workout!

you havent ran out of fuel in a diesel before then,i drive a diesel by day not good when you have to bleed an injector to release the air.

sorry to hear your luck is getting worse scott might be best to change the other two coilpacks together or change one and save for the other.
dont want your car running on two cylinders for too long or it could kill the cat or worse your head gasket.
