Morning all, Customer organized through internet a company to come to his house to "chip" ecu . Car the would then not start so they replaced original chip still no start. They then obtained a used ecu car started and they cleared off shapish. Car drove for 2 miles then stopped. This is when I was called. Pluged in ACR4 , ECU blocked! Cleared codes and started and ran for a few mins then cut out . Now no comms, no go. Who is the best company to check ecu . We are in newcastle area ,thanks.
