MYSTERY ISSUE. Doing my head in. Please Help!

Do you have a dual mass flywheel?, hard to answer I know unless you had one fitted.
They do weird stuff when the start to fail.
Whatever it is it should show up on the test you are talking about, all very interesting.
Long gone are the days of listening via the end of a screwdriver!

Not sure about the dual mass flywheel.
Some have said the TB45 didn't have one, some say they did, I don't know either way.

Cheers,
