In fairness, that arm does not sit at 90° between the vac actuator and flap lever with the flap lever about 5mm or so to the rear of the horizontal plane across the manifold. The forward trust this induces on it may be contributing to the arm popping off the flap lever.
The best arms I've seen yet are the Polish eBay metal ones with the spring lock ball cups. You can make your own to a similar design too. |
I thought that the problem with the Gruven / Polish metal arms was that they have been designed as plastic by audi to snap if the manifold flaps get stuck or seize, so that less damage is done and the whole lot isnt toast?
