| OK I hope..
..they can help you and find some kind of solution to this problem. I am not saying that you have done something wrong but IF that is the case, I think they will come up with a decent proposal and help you out. And one thing is for sure, I have to check if that lamp is working!
If it had worked, it would of course be visible that u had very low oil pressure and this would never have happened. One more thing: u said u had the car fixed some time ago. I am thinking why did they not check that lamp at that time? I mean, it is very important that is works! I think they have made a mistake here, but I guess they can always say "We did that, it must have broken recently". This is crap... |
