The symptoms or: Trouble Shooting

The controller starts by the lack of suitable data "to behave funny. (Humor who can laugh at such jokes about) most often jokes comment on this non-circular, or to a high idle, spontaneous death of the motor, buck, stuttering, misfiring, popping in the air filter housing, poor throttle response in low etc. pp. He also flooded usually hopelessly in which soot cloud from the exhaust and high fuel consumption while poorer performance leads to.

If you now conduct your minis in the list find again that would be the vacuum hoses a very hot tip.

What breaks?

It is mostly tips, the hoses and tear or by the ever-hot environment caused by old age begin to crumble. The hoses themselves are too brittle to get holes / cracks or already rendered unusable by kinks. If no external damages are, there remains the possibility that they are blocked simply expand (if working with compressed air will blow out completely before the tubes!). The hoses are flexible, although limited, but not rubber - that is to carefully work around unfortunately. In rare cases, the case of petrol leaking or overflowing offender, except to say, eight have not. If it is filled with gasoline, it can be expanded and freigeschüttelt. This requires quite a bit of patience.

The "hierarchy"

Let's get the yellow hose to the snorkel. It connects the valve with the ThermAC ThermAC switch. The valve is used during a cold start to the fact that as soon as possible to the engine block pre-heated by air drawn in is to rapidly provide proper exhaust emissions. How the switch works exactly, I do not know, but I think it can, depending on the temperature (should be a bi-metal switch) be something of the pressure valve in the snorkel through to fill this order - if necessary. The switch should operate in both directions, Wierum the hoses are connected not have to worry. (If not please contradict! Bin as well versed soo not.)

ThermAC switch from the red hose goes to the intake manifold. (Photos from the engine coming soon. As long as simply hope that the old bottles are still there to hinzuhangeln around.)

From there is the short hose (in black / white) for connection to the gas trap. The petrol is the case, held by a bracket on the fire wall (separation between the engine and passenger compartment) to the left / behind the air box. Remove the Lufi best, makes it easier to work a lot easier.

The connections are designed so that a "reversed polarity" is almost impossible (but "is not" is not, therefore, to note that the management ECU ran to the green connector to be! ). The long, green-coded cable leads for connection to the underside of the ECU next to the connector of the engine wiring harness.
