Bmw 118d low revs on start up

[Scottmaloy]

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

The egr valve on my sons Toyota pickup clogs as he only does fairly short local journeys, the first time we cleaned it and the inlet hoses it worked fine the second time it looked fine but just didn't operate when it was on the car for some reason. New EGR fitted and all good again remember to clean the inlet pipes and hoses as well his were in a dreadful state.

P0401 is a generic code a BMW diagnostic would be better, as you have a hard peddle are you sure all the vac lines are in the right place?

+1 on the EGRV. They are a weak point on Beemers, amongst others. 

Mine lasted 5 years and 45,000 miles.
