Ive just bought an 03 plate Sportka, the day after i got it home the engine warning light came. I took it back to the garage and they told me it was a fuel pressure fault because the car had been run on very low fuel for the last week or so so when i filled the tank the ecu spat it dummy out. They reset the ecu but within 5 miles the light was back on. I booked it to go back in to the garage for it sorting but in the mean time i got a new head unit fitted.

Now the car has been with them for nearly a week now and there saying that the diagnostic machine cant read the ecu due to the radio been fitted.
Ive never herd of any thing like this so i just thought id ask if any one eles had.

Thanks
