Oil pressure issues on my b2 cq

[andya]

Hi all. I've got an issue with the CQ. About 6 weeks ago I had the oil pressure light and buzzer coming on over 2200rpm and only when the engine was hot. I solved it by replacing the high oil pressure sender unit. Fast forward to last week, and I was travelling back from holidays having done 1000 miles of trouble free cruising and the buzzer and light came on again on the a303. I freewheeled off at a convenient slip road. Once I dropped below 2100rpm the buzzer and light went, but at idle, I had a flickering light. I decided not to continue at motorway speeds and went back home the back roads keeping my speed down.

Since then I've looked at both senders again. Their fine. I've changed the relay, that's made no difference. Any ideas? It's putting my spot at next week's AITP in jeopardy, so if anyone has any ideas let me know! I certainly wouldn't want to risk the journey up to Northamptonshire if it's not right
