hi all im obviously new here , ive been driving a volvo 850 t5 with 350 bhp for quite a while but fancied an s4 instead so yesterday i went and baught one from leeds (i live in stratford upon avon) so quite a trek. well the s4 i got is a 98 and i love it. i have got a few questions though so id appreciate any feed back very much. 1. on a standard car at what rpm can i expect the turbos to really kick in ? they seem to hit in hard at 4200 rpm is this normal. as the volvo used to surge in at 2300 rpm but it was chipped......
2... are the turbos an engine out job if they blow?
3... ive noticed that occasionally the fuel gauge needle drops right down for a few seconds which puts the fuel symbol on and beeps then jumps back up to the correct position again and the symbol goes off again , this usually happens when i go over a bump or if im braking. ..any ideas?
