Leon struggles when cold

[lee25]

hi all,

My leon turbo has started to struggle slightly when cold, when i start it up on a morning it will sound almost as if its only firing on 3 cylinders, and when i pull away it hesistates and runs terrible, it will only last maybe 30 seconds until the engine has run.

I have a boost gauge and when its running like it does i find when its on tickover, running in vacum it drops to around 0.5 whereas when running normal its around 1.5. Ive only had the car a few months and its only started doing it since ive had it remapped around a month ago.

Any help would be appreciated, cheers

I had this with my old VRS,coolant temp sensor change helped,but tbh leaving the 20vt to idle for a few minutes before driving off is good practice.
