“2006 Jaguar vdp l wb would not exceed over 10 MPH and warning lights illuminated on the dash. Experienced two massive fuel leaks. The dealer claimed they replaced a seal to fix the fuel leak, however 2 weeks later the fuel leak resurfaced. The dealer then stated the left fuel pump flange was still leaking and the fuel tank was warped. The problem with the vehicle not accelerating over 10 MPH was due to a loose mass air flow sensor connector. The tire monitor was faulty.”
