Hi this is a new thread linked to a long standing issue with my petrol 2003 V70R Estate (B5254T4) which has been cutting out. Its been with three different garages so far but with no cure. Its had a new pump, FPS and a replacement PEM all to no avail so far. Previously it had been thought that it was cutting out at high revs but I am now 99% certain it happens when the fuel drops to around a quarter full in the tank. When the tank is full it runs like a dream but after running it for a week or so the problems re-occur as the fuel level drops. It first starts missing a beat then gradually gets worse and worse till it either goes into limp mode or just dies completely (thats scary!). I have seen a diagram of the saddle tank and whats going on in there looks mind blowing (to me at least). The question is can anybody help me with sorting this problem or does (as I suspect) the whole tank need to be replaced?
