:blink: Hi gerryh, My '03 115TDi was doing the same thing occasionally. Apparently the Turbo Boost is controlled by an adjustable vane mechanism which is prone to sticking if the car is doing a lot of light work - town driving etc. Other members with similar problems suggest giving the engine a "good workout". This advice seem to have worked for me. No recent issues. Well John anytime it happens I try fiooring it but no joy allthat seems to happen is lossof fuel :D but i must look in to turbo problems thanks let u no if i get it fixed
