P38 2.5 dhse - strange starting issue only every 3 starts

If you have MAF fitted then ignore the air temp as that will be a default value

That water temperature looks odd though.

Can you get it up to normal operating temperature (needle at 12 o'clock) and then record a trace onto an SD card?

I'll dig out my PC and try to find an old trace of mine (it'll be on this forum somewhere) although mine's pre-EGR and MAF so won't be exactly the same.

With the battery voltage so low, it's likely all the figures are nonsense.

Datatek - the battery came with a sticker on it stating not to charge so I didn’t charge it before fitting. I purchased it from battery mega store as suggested in other threads/posts. Should I try charging it or possibly contact battery mega store and see what they say.

Grrrrr - I haven’t had too much of a play with the nanocom but will try and work out how to do a datalog onto an sd card. Im sure there will be a write up or video knocking about somewhere if I can figure it out.

once again thanks to everyone for all the help and suggestions.

on a side note could it be an ecu issue? Or bcm issue? If so would a replacement ecu need coding? And is so could I use the nanocom to code it?

Are you sure it said "do not charge" and not "do not charge before removing shipping plugs from the vents"? Batteries always need to be charged before fitting, the battery may have been on a shelf for weeks or in shipping as they come form Korea.
Personally I would put it on charge for at least 24 hours, maybe longer as it's totally flat, then leave it for a couple of hours and check the voltage, it should be 12.8 volts or at least 12.7 volts. If not then the battery may be fecked.

Fixed !!! - Sorry just had a message about my issue and realised I forgot to post about the solution to my issue. My car has been fixed and daily driven since feb/March without issue.

So if anyone is interested or is having the same problem.

The cause of my issue was one of the solder joints/legs on the ecu chip having a crack/poor connection. Resoldered the chip with decent lead solder and it’s been starting and running well ever since. So if you have the endtuning or another brand tuning chip fitted and having a similar issue id suggest starting there before going down the rabbit hole I did.

Aftermarket modifications are always a good place to start!
