Hi I'm Kevin you need to go to live data viewer and get cylinder missfire values up
Group 15 and 16 from memory should show cylinder 1-4 and then you will know what cylinder your missfire is on
So all 4 are showing misfires?
Ok this it very ,very unusual to have all four showing misfires I have used the vcds for the last 10 years and have never seen this normally 1 or 2 but not all four . And on the group numbers I gave what are the wording underneath ( just wNt to make sure I've you the given correct numbers)
Your engine has 4 seperate coils yes?
What's the wording you have for group numbers?
Ok let's get some history the car had any work carried out recently? Any water in scuttle area by wipers
Ok so issue not there all the time did you see my last message?
Ok and whets the history of car any water ingress in wiper area?
Ok so at the mo which cylinders are worst?
If you come back out of measuring groups is the advanced measuring groups button avaliable?
If it is select cylinder missfire 1,2,3,4 from the list
So this is on advanced measuring values now?
Ok there is not consistency to the location of misfires what's the history of the fault have you had car long has it always missfired?
Has timing belt been done ? Had any fuel in it from can?
The reason I'm a lost is that all four are misfiring very irregularly and the likely ness of all four coils or all four injectors being at fault are slim.also the chances of cam and crank sensors failing again are slim so for me it's either a timing problem,a fuel issue (bad fuel) or an ecu problem
I mean if you going to put belt on it I would but I would be more inclined to believe either bad fuel or ecu as it comes and goes also
Does tank have much fuel in?
I would start with fuel and maybe add a fuel cleaner in there also
Seafoam will be fine and compressions look good which really rules out belt
Yeah question stays open I'm gonna do a bit of research and come back to you
Also what are the exact fault codes you have?
Normally a new question but What's the code
With the code will be a description don't suppose you have it
And the part you replaced with had identicle part number?
Ok and airbag module is original ? No accidents
I suspect you have a crash sensor that although is the same number is ***** the same model and is not comparable with the module you have fitted
Water is very common no calibration should work straight away
Ok no worries I'm in the uk and it's getting late so dependent on time I may not be online but I will come back to you as soon as I can
Let me know how you get on after running
I've not come across this before you said before you have another car with same engine have you tried swapping all could over ?
