I have a few questions about my 118d,recently purchased a bmw 118d 2006,had a blown turbo when bought,now turbo is in and it’s running.but I’ve noticed a few hiccups,when first starting the car it doesn’t like to rev ,I have to be patient and eventually it will rev,like it needs to clear.will do this low revs for 5-10mins.then will drive fine.also my brake pedal is hard on low revs,maybe a vac leak but I’ve looked and can’t seem to see anything.its driving me crazy.ive cleaned the inlet and don’t have swirl flaps,cleaned the egr and car keeps coming up with p0401.just want to get to the bottom of this .would appreciate anyone’s advice as I don’t want to keep buying parts unless I need them.any advice please?many thanks in advance
