Yeah fucking hopefully?!
I think a call to CTS is in order to see what they think, if it's wear they will no straight away, and if it's wrong oil then i'm sure they'll know that too!

If it is a shit box then i'm not happy as I bought that from someone on here who swore blind it was a good box!
Lets just hope i've used the wrong oil!
Might have to keep my eye open for a low mileage IB5 box though and slap my Quafe ATB in that if need be!
