Hi guys I've got a 240 cupra. It's been in and out of the garage for about a month my revs drop very slowly back to idle (it idles fine)but there's no fault codes coming up. Me and the garage and scratching our heads we've tried to mag isv air leaks etc but nothing. Have any1 had this problem or could point me in the right direction? Thanks in advance

Check timing. Make sure aligned properly as sounds like one cam is out causing back pressure. Or possibly oil breather from bottom to top of engine blocked....
