Evening folks, Was doing an oil change in my wife’s 1.2tsi earlier (along with the breather valve replacement), all going well until I started the engine which sounded really rough at the top end. Took it round the block, still noisey. Bit of searching on here and found a few threads on filter o-ring being left in. Filter off, found the o-ring, all good. Engine still sounded rattly but a bit quieter…drove home and when I came off the motorway the oil pressure light came on. Pulled over, checked everything and all good. Decided to head to my local garage and just leave it there till tomorrow. Any thoughts on this? Engine sounded fairly normal by the time I got there but the oil pressure light came on twice again (stopped both times to check everything). Have I lunched the engine?
