Loses power problems

Electrical system failure

Audi A4 2002
In 2004, when driving a long distance, the vehicle suddenly lost power, the accelerator stopped responding with its evident risk, and the EPC light turned on. It was momentarily solved by changing 4 spark plugs and 4 ignition coils. But, after 20 days, the car started having the same failures again. I took it to another mechanic this time, who replaced the fuel pump and told me the spark plugs and ignition coils had nothing to do with my problem. Actually, he explained to me that my real problem with the fsi is in the fuel, which needs to be of 99 octanes. However, this fuel is not available in my country, so there is nothing I can do to solve it. So, check carefully before buying an fsi.
