hi everyone im not to sure what to do on this forum as I have only just joined but here goes I have an audi a4 cabriolet 04 plate oil pressure light came on with a bit of a rattle at the top end of the engine had the oil pump replaced and the feeder pipe but it is still exactly the same as it was before the work was carried out when the sump was cleaned there was a small piece of black plastic that had obviously broken off something it is showing some oil pressure but not enough to feed the top of the engine has any one any ideas as to where else the problem could be thanks in advance
