Feilkoder - 1998 Passat 20v 125hk.

[Aorak]

Da fikk jeg feilsøkingsutstyr i posten idag og plugga opp og fikk litt forskjellige feilkoder.

 

18010 - power supply terminal 30: voltage too low.

00561 - Mixture Adaptation: Adaptation Limit (Add) Exceeded

17916 - idle Control Sys: Upper Regulation Limit Reached

16486 - 16486/P0102/000258 - Mass Air Flow (MAF) (G70): Signal too Low

 

klarer og forstå at jeg nok har problemer med luft sensor som muligens forklarer hvorfor jeg føler at jeg kjører med 125PonyPowers :assman og hvorfor bilen hakker når jeg kjører spesielt på turtall rundt 1500-2500.

 

noen som kan fordype litt for meg på ting det evt er? kjøpte tennplugkabler idag, men kom hjem og fant feilsøkingsutstyr i posten, og ingen feilkoder som tilsier at det er noe galt der?

 

takk for hjelp på forhånd!

18010/P1602/005634 - Power Supply B+ Terminal 30: Voltage too Low

Possible Causes

Cables on the Battery were removed

Battery weak (voltage)

Generator Disfunction

Possible Solutions

Check Battery Cables

Check/Replace Battery

Check/Replace Generator

Special Notes

If multiple Control Module have Power Supply Faults stored, it's most likely to be one common Problem like the ones shown above. Otherwise when only one or two Control Modules have such Codes stored you better start searching at the individual Power Supply of these Modules.

Terminal 30 means unswitched battery power that is supplied even when the ignition is off. This is not referring to any physical terminal numbered 30.

00561 - Mixture Adaptation

00561 - Mixture Adaptation: Adaptation Limit (Add) Exceeded

Possible Symptoms

Engine Jolting

Increased Fuel Consumption

Poor Idling/Jolting

Reduced Boost Pressure

Possible Causes

Mass Air Flow Sensor (G70) faulty

Fuel Pressure too Low

Leaks in Intake Air System and/or Exhaust System

Injector(s) faulty (i.e. coked)

Possible Solutions

Refuel Vehicle

Check Fuel System Pressure

Check Mass Air Flow Sensor (G70)

Check Intake Air System and Exhaust System for Leaks

Check Injection Quantity

Check Injector(s)

16486/P0102/000258 - Mass Air Flow (MAF) (G70): Signal too Low

Possible Symptoms

Probably no serious malfunctions

Loss of power

Possible Causes

Wiring and/or connections (short circuit?)

Mass Air Flow (MAF) (G70) defective

Possible Solutions

Check wiring and connections

Check / Replace Mass Air Flow (MAF) (G70)

Special Notes

In MY 1995-2002 (?) in Europe at VW-diesel-cars G70 had the bad reputation of slowly losing his performance, causing loss of power. It's not a matter of defective or breaking down, but it is filthy / dirty (not easy to clean). You can check functionality by making a log in [01-engine], [meas.blocks-08], group 003 (3e gear, full throttle, from 1700-4000rpm)

Sensoren inni MAF-en blir ofte dekket av skitt etter X år. Med litt flaks kan den få noen ekstra års levetid ved å skru den opp og vaske den med elektronikkrens og q-tips eller noe lignende.
