    Hi,

    Don’t know if anyone has any previous dealing with their Golf GTI MK5 not starting up in hot weather? Taken to multiple garages and spoke to mechanics and none have any idea what the issue could be.

    My car starts fine in winter and cooler months but struggles to start when we are having a little nice weather. Luckily this is the UK so we don’t usually get really hot weather but I need to sort the issue out.

    Thanks for reading :)

    This may get moved to technical section just a heads up

    I have heard of crank sensors breaking down on the fsi and tfsi when the engines are hot

    Hi there, I’m totally new to this site. Do I need to post it somewhere else? Will mention crank sensors when the garage reopens though thank you

    By not starting do you mean it doesn't crank over, or just takes a long time to start?

    I guess it's needing someone handy with diagnostics to check fuel pump pressures and operation with live data to see if it's a fuelling problem, same goes for the above suggestion of a crank sensor failure.

    It's one of those faults that needs diagnosing when it's playing up, not easy!

    I’ll take it back to the diagnostic guy I took it to before. He just changed the battery as apparently it was giving off no reading like it was dead. Obviously it wasn’t that though as it’s continued. Thank you
