| Quick checks with assembled carburettor AUDI / VW | |||||
| 1. Remove air filter, check prethrottle for smooth running (engine shut off, ignition off). | 5. Perform leakage check onvacuum unit of 2nd stage. | 9. Check idle speed control, engine at operating temperature. | |||
| 2. Perform functional test of intake air preheater (function of thermovalve). (Vacuum unit leakage). | 6. Check bypass heating forcurret by means of test lamp (in series). | 10. Call flash code for idle CO sensor at operating temperature. | |||
| 3. Check intake manifold preheater (hedgehog), Disconnect thermoswitch in coolant circuit and energize hedgehog. Within 2 min 120°C must be achieved. | 7.Check electric float chamber switch valve (switching noise). | 11. Read error buffer. | |||
| 4. Check intake manifold and rubber flange for leakage (particulary lower side). | 8. Check all terminals for corrosion and firm fit and cable loom for correct wiring. Si0019 | ||||
| Maintenance Carburettor 2E-E AUDI / VW / Mercedes-Benz / OPEL | |||||
| Complaint : | Possible Reason : | Remedy : | |||
| Engine does not start in cold condition. | Temperature sensor/primary throttle acuator defective. | Replace temperature sensor/primary throttle acuator (F1). | |||
| Engine stops after cold start driveability. | Heater honeycomb failed (Mercedes-Benz only). | Replace heater honeycomb (presrntly no Pierburg part). | |||
| No/poor idling after cold start (2 to 3 min). | Rubber flange distorted on lower side (not detectable by spraying). | Install rubber flange 3.50001.33 VW (R1/R2/R3) Mercedes-Benz = 3.50001.31 / Opel = 3.50001.32 | |||
| Poor driveability with cold engine. | Intake manifold preheater (hedgehog) failed (check temperature according to check list). | Replace intake manifold preheater (2) 4.07316.02 | |||
| Poor driveability particulary with cold engine. | Armature of primary throttle actuator turned. | Check primary throttle actuator with ring gauge."Caution:do not apply battery voltage", and replace, if necessary. 4.07360.07 + Ti206 | |||
| Poor transition during acceleration. | Throttle valve potentiometer/ primary throttle actuator defective. | Replace throttle valve potentiometer (B1/B2) /primary throttle actuator (F1). Ti191 | |||
| Idle speed not constant (control failed). | Throttler valve actuator/throttle valve potentiometer devective. | Replace and adjust throttle valve actuator (C1/C2) /throttle valve potentiometer (B1/B2) | |||
| Temporarily no iding with engine at operating temperature. | Charcoal valve stays temporarily open. | Check by disconnecting hose, replace valve, if necessary. | |||
| Engine speed remains temporarily high (approx,3000/min) when slowly reducing accelerator position. | Check throttle valve actuator potentiometer as described in Ti194 . | If resistance valve jumps, replace throttle valve actuator. | |||
| Temporarily or continuously elevated idle speed. | Plug connector of throttle valve actuator loose (occurs ofter, since cable is short and throttle valve actuator difficult accessible) . | Check throttle valve actuator, replace, when high resistance is indicated and fasten plug connector securely. | |||
| Engine idles erratically. | Mixture control screw (RG)misadjusted or lambda sensor defective. | Check CO adjestment (flash code), check lambda sensor and replace, if necessary. | |||
| Rough idling, part load jerking, idle speed not adjustable. | Rubber flange leaking. | Replace rubber flange (R1/R2/R3) , check idle setting. | |||
| Motor stops during deceleration after wide open throttle driving. | Main jet cut-off defective, | Replace main jet cut-off. Set 4.07304.02 adjustment to 1,5mm between jet support and plate. | |||
| Poor starting in hot condition. | Float chamber switch valve defective, engine overflow. | Replace float chamber switch valve (K1). | |||
| Poor driveability with hot engine. | Vapour bubble formation and foaming of float chamber. | Install pressure regulator 7.21517.02 between vapour separator and carburettor. | |||
