Volkswagen Touareg / Touareg repair>> Engine>> Preliminary checks on the car>> Compression check (the diesel engine 5,0L)
NOTE
At this type of engines compression check on the motionless car is interfaced to labor-consuming operations. Therefore it is expedient to inspect idling control before these works. Measurement of a compression is expedient only if there is a suspicion on failure of cylinders / cylinders.

NOTE
Necessary special adaptations, control and measuring devices, and also supportive applications:
– Dinamometrichesky key (5–50 N · м) V.A.G 1331;
– V.A.G 1381/12 adapter;
– Kompressometr V.A.G 1763;
– A protective plate of T10247 (Cars with alphabetic references of the engine AYH, BKW);
– A connecting hose of VAS 6278 (Cars with alphabetic references of the engine AYH, BKW).

Check conditions
Temperature of engine oil of minute of 30 °C.
Ignition is switched off.

Procedure for test
Merge cooling liquid.
On cars with alphabetic references of the engine AYH, BKW dismantle the fuel filter.

Connect топливопровод A a connecting hose of VAS 6278 with toplivoprovody B (fig. 2.16) .
On cars with BLE and BWF engines remove a bypass cover with a radiator of system of a retsirkulyatsiya.

Continuation of assembly operations for all cars
Remove the top part of a cover of the case of the oil filter.
Remove glow plugs.

Remove the right cover of a water taking away box D (fig. 2.17) .
Disconnect small shtekerny connection from control units the engine.

NOTE
By means of shutdown of small shtekerny connection the condition at which, despite a working starter, the engine it will not be got is reached. At engine start in memory of malfunctions there will be mistakes. After work on measurement of a compression it is necessary to consider and remove mistakes.

After measurement of a compression interrogate memory of malfunctions.
Twist the V.A.G 1381/12 adapter in a nest of a glow plug of the checked cylinder.
Establish the top part of a cover of the case of the oil filter.

Fig. 2.18 . Compression measurement


Measure a compression by means of the device for measurement of a compression of V.A.G 1763 (fig. 2.18) .
Twist a starter while indications компрессометра will cease to increase.

Compression indications
The new: 25±0,31 bar of superfluous pressure.
Limiting admission: 19th bar of superfluous pressure.
Admissible difference between separate cylinders: 5th bar.
Establish glow plugs. Fill in cooling liquid. After check of all cylinders and a full ukomplektatsiya of the engine, interrogate memory of malfunctions and remove mistakes.
