Before you buy a new TA, what it specifically complains about is the enable line into the TA. In German it says it is interrupted. This enable line comes from the DME through the harness. It may just be a harness wire integrity issue when you ruffled it feathers under the hood. The way to check this is by switching the TA in place and see if the problem moves to the other side. If it stays it is the harness if not it is the TA.
