It doesn't seem to happen when the engine is cold, only when the car is warmed up and when i change gear at higher revs. Anyone had similar problems? How do i tell if it is the Synchro?My 2002 Audi TT Quattro is crunching in 3rd Gear. How do i tell if it's the Synchro or just the gearbox oil?
It's probably not gearbox oil, since your manual gearbox uses your engine oil to lubricate it, so unless your car is low on engine oil, the oil level in your gearbox shouldn't be an issue.
Its probably a synchro especially if it happens at high rev's. If it only happens when your shifting fast, then it's a synchro. It's not a problem if it only happens in that situation it's pretty normal. but if you keep shifting hard at high revs and hear that crunching you'll wreck your synchros.
