Thanks for the suggestions. The code reader I had at home the other day at can't do the live readings, hence why only going off the codes.

Thanks all, I agree, unlikely to be timing based on the symptoms, have also read up a little bit on setting up the timing with the 'floating' pulleys, so the painted marks could just be academic.
...
Cheers for the offer, though having doubts it's entirely MAF related...
Removed all coils/plugs, found the plugs all covered in black soot (confirming poor mixture), but all the same so ruled out...
Thanks guys
As it happens, the local scrappy had a c70 turbo in with a maf sensor with the same part number- result! (Also checked the one way valves but both already failed)
Got home and...
Hi
After some head scratching and some very helpful guidance from Martin (M-R-P), the decision has been made to try a new / known good MAF sensor.
Can anyone offer any help with deciphering...
Well, decided to go down the dealer route. Now have a car I can drive without unexpected hesitation moments, hopefully going to stay like that! Now to move on to the other bits and pieces it needs...
Hi
Having been suffering with a gradually failing ETM, it's got to the point where i need to do something about it.
Question is, which route do people recommend going down:
A) Sending away...
I would expect as much, was more an exercise in diagnostics (haven't got round to sorting my DiCE out yet), at least it comes with a 1 year warranty, apparently.
Well I finally got round to having another look, checked for air leaks etc. I noticed that it seemed to run better with the MAF disconnected (although with a rough idle). So I bought one the cheap...
Thanks, will give it a go, probably won't be until next weekend now though. When connected to the car, the DiCE firmware light was flashing green constantly. There was no light for the USB or car...
I removed and cleaned the throttle module yesterday morning, still no improvement. Went to read the codes (if any) and reset adaptions if possible with Vida, but my DiCE unit decided it didn't want...
Well, Dream3r (ECM-tech) confirmed the old ECM was cooked (the water ingress had affected the immobiliser chip inside the unit, hence why it couldn't communicate), unfortunately this meant he...
Well, finally got hold of a spare ECM... Tried plugging it to see if it communicates - obviously it still doesn't start but it does at least bring the EML on with the ignition now, proving it is now...
That's a good shout, and exactly the reason why it's important to test for voltage / volt drop with the system connected and switched on - open circuit (ie component disconnected) voltage readings...
No worries, i did check the voltage on both sides of every fuse in the under bonnet fuse box and the drivers side dash fuse box with the ignition on, all live (12v ish)
Edit: also worth noting...
So, it looks as if my ECM is not booting up (does not light up on Vida), what would you suggest is my best option?
If I was to send my ECM with another doner unit and you were unable to clone it,...
Well I now have Vida/Dice, and have read the codes. As predicted, there is no communication possible with the ECM, with code CEM-1A62 (communication with ECM control module signal missing) stored.
...
Yeah, i kind of got that impression after seeing them - no good unless you actually know what the codes are...
Bit of an update...
Still waiting to get codes read with VIDA, but in the meantime i've checked a couple of other things.
Firstly, I can confirm there is a 12v and a 5v feed to the MAF sensor...
LeeT5, thanks for your comprehensive guide. I am very much aware of a methodical approach to fault finding and have probably checked half of your list in roughly the same order (as much as I can do...
It could be to do with the crank sensor, as i've said before, the lack of EML could be a red herring (and to be fair, i've been going down that route so far)
I will give that a go when I next look at it, probably won't be until the weekend now though. I have checked all fuses in the drivers a-pillar and under-bonnet with a multimeter (both sides), and all...
No, not yet. Primarily trying to communicate with ECM first before looking at specific items. Though when I initially started looking at it, I did try starting it with the MAF disconnected (no joy)....
Hopefully will be getting it read with VIDA in the next week or so, going to leave it until then.
Thanks for everyone's input so far.
Other updates:
Still no further in finding anything definitive, so it looks like I'm going to need to either send the ECM away for testing and/or get a VIDA/Dice and have a go with that.
The...
