Have this 2020 Sagway snarler at6s that has 326km on it. Completed first service at 300km and cracked Downpipe. Sinced replace, the quad has no loss of power, stalls the odd time and doesn’t have the 4wd diagram showing on its cluster. Traced fuses and dealer has had the quad for over 2 months, returned it back to me with these lights still on saying “drive it 2kms and watch it restart”. 26kms since full service and once over and vehicle still flashing oil pressure and opc ( 4wd picture/symbol not appearing on cluster ) ANY ADVICE?
