Hi, so thought I'd ask the forum this when I go to work at 6am in the morning my car starts fine no issues even when cold I then drive 6 miles to work and leave it there till 4pm when I leave work and try start it it cranks over few times then starts and kicks out smoke , then drives and starts ok after that , then drive 6 miles home and leave over night till 6am an no starting issue only when I seem to leave work

Smoke suggests it's stuck in cold start mode, which points to a temperature sensor?

Is they any way of me testing the temp sensor ? And is this the coolant temperature sensor as funny enough my temp gauge goes up fast and stays in the middle

There is more than 1 temperature sensor, I think it could also be the one measuring intake air temperature - so rather than guessing I suggest a code scan.

I have a diagnostic machine , launch x431 pro and it only has these

Do you have a friend with either OBDeleven or VCDS - they give a much more in depth report?

Unfortunately not no I presume OBDeleven is the Bluetooth one to your phone ?

No idea, I use VCDS and a Windows 11 2-in-1 laptop but lots of people on here use OBDeleven.

My diagnostic machine should work though surely it's up to date and Its bidirectional or do you mean specifically for Skodas ?

I mean one that properly understands VW Group vehicles and their specific fault codes, not just the generic OBD fault codes.

Ah yeah I see what you mean, I'll have to have a ask about or take a drive to yours haha

This should have been the first question. Check the glow plugs.

I was told if it starts in cold weather without issues then won't be glow plugs I'll have to get a multimeter out on them

Issue apparently solved was a split line to the fuel filter now been replaced seems to have sorted it
