151 nissan x trail diesel slow to heat up. The heating gauage on dashboard is slow to get to half way. No proper heat on the air vents, its cold to drive around

Any advice would be helpful

You have just described the typical symptoms of a faulty thermostat. Sounds like it's stuck open. Normally an easy repair but I don't know that engine layout. YouTube is your friend and your local motor factors should have a stat in stock.

All diesels are like that. They heat up so slow compared to petrol cars. The reason they are not economical for short journeys

I find the opposite, its great for short journeys

In what way?

Diesel engines only run efficiently when properly at temperature, and if you are only making frequent, very short runs, it won't get to that temperature.

Does sound like Thermostat issues alright. However, I had a similar age Qashqai and it turned out to be a blocked heater matrix which was an expensive fix.
