ok just bought a bmw 1999 520i auto when i start the car and drive it it drive great but after around ten minuites when i need more power its not fully there if i use the kick down the power is not 100%
if i stop the car and start it again the full power is there and the kickdown is super as it...
I bought a 1997 'R' plate BMW 520i yesterday, 90,000 miles, full service history, but the car has only done 4000 miles since June 07 when it was last serviced. The car feels massively underpowered almost to the point I think it's going to stop going up a hill. I have a Diagnostic man coming out...
