which dipstick do i need?

what part number dipstick do i need for "caga" engine a5 2.0 tdi 2011

I was given part number 03L115611E but turns out it was too long.. 03L115611AC fitted mine perfectly but it's an 8T A5 2.0 TDI S Line.. not sure what my engine code is but it's a 63 plate. eBay has plenty.

Make sure you check the new one against the old. The plastic top on mine was broken off, so I bought one on eBay, which was wrong.

I then orderd one by the VIN from the the local VW agent, which was found to be wrong when it arrived. The second one they got was correct.
