I think I made it clear that this was a historical situation, and I did not by any means suggest that one should do this today. I hope that it did not read that way! But maybe your suggestion that something was lost in translation in the owner manual is the correct answer. Good thinking Bill.
I guess that I’d better not tell you about when I put some petrol in an A4 1.9 TDI in around 1998, when I had a brief and rather inglorious career working as a sales executive at an Audi dealer. Those mechanical fuel injection engines were a bit less fussy, fortunately, and I think they just towed the car back to the garage (from where it had given up on me), drained the tank, refilled it with diesel, and put it back on the sales display! Always good to hear from long-time readers, and I hope that we can continue to deliver you both entertainment and enlightenment. There’s a huge database of knowledge and experience in our readership though, and it’s great to have information travelling in both directions. Best regards and thanks.
