I've searched and couldn't find what Im after.Its a 94 300tdi with snorkel and extended breathers.Today at Tidworth my disco started to miss and cough after having fun in the wet stuff. Its never done it before,but then I've never been that relentless splashing before. It wasn't smoking,just very start stop when the throttle was pressed to the floor and at one point I switched it off and it wouldn't start again for ages as if it had dried out.It drove the 2 hour drive home fine.My question is have I missed waterproofing something or is it a sign of bad things coming?
