Hi. I have a weird problem.

I have a vw golf mk4 with a 1.9 tdi engien.

My problem is that when its hot outside the car has less acceleration compare to when its cold outside.

I noticed that every day when it hot outisede the car has less power but when it gets dark outside and the outside temperatures drop the car goes and accelerates better.

Did who had a simular problem?

Basic engine fundamentals at play. Cooler air is more dense so every stroke pulls in more air giving a better combustion and more power . 


Jes but i had other cars that didt do that.


Turbo engines will be more noticeable
