I have a 2020 plate Audi A1 35 TFSI, on 2 occasions since purchasing the car I have put Redex into the fuel tank. Each time roughly 2 weeks after doing this a Drive System error comes up on the dashboard. I plug in the reader and it comes up with PO148 fuel delivery error.
Error only comes up on the first engine start of the day.
It seems to clear after a drive on the Motorway although not 100% sure on this or whether I accidently press to clear the code on the reader. The first time it did it, the error didn't return until roughly 2 weeks after adding redex about a month later.
Anyone had this before and what I need to do? Cars going into Audi in march for another issue so will get them to check then but the drive system error isn't showing up at the moment
