Check the position of the hot-film mass air flow sensor on the sealing plate before tightening the screws; no light gap must be detectable during visual inspection.

6. Generate a pressure of approx. 0.5 bar. With this pressure generated, a clearly audible blowing sound indicates major leaks whereas minor leaks can be made visible using a leak detection spray.

Note

The pressure relief valve of the oil tank opens at approx. 180 ± 20 mbar. Seal the valve; to do so, remove the front wheel housing liner from the rear right-hand wheel housing. Use an appropriate plug to seal the molded hose from of the pressure relief valve.
