Climatronic feil

[Blanklaks]

Hei

For ett par dager siden begynte plutselig displayet i climatronic panelet og blinke ca 15 sekuner hver gang jeg starter bilen og komressoren starter ikke

kompressoren er bare halvannet år gammel så jeg tror ikke det er den som er ødelagt, har også sjekket sikring

dette er en Passat 1.8 liter 4motion 99 mod.

 

Noen som har forslag til hvor jeg bør begynne og feilsøke

 

Takknemlig for alle forslag

[Mondeo]

Let litt på nett. Det skal gå an å få ut feilkoder direkte i displayet, men jeg vet ikke hvordan

[Blanklaks]

Å jeg har søkt og søkt men finner ikke noe

[JChE]

sannsynligvis tomt for/for lite kjølemedium... da starter ikke kompressoren.

[Satanoperca]

rota endel med anlegget selv

jeg har kode 466 funnet ut at det må være klutsen til kompressoren .

 

 

VW Climatronic (by Hella) Self-Diagnostics

Original Author: Roger, Location: Greater Frankfurt am Main Posted on: 09-09-2004 Original Title: Eigendiagnose an der VW Climatronic von Hella

Translation by: Nate (AKA VWAffe), 16-08-2008

Here are a few instructions on how to decipher useful information from the VW Climatronic control panel. Especially attractive is the fact that you do not need any sort of diagnosis equipment, and can read out one value or the other while stopped at a light, for example.

The description of reading error codes, performing the control surface test, and onboard-diagnosis is limited to the Hella control unit, as pictured below. This unit is found in the Golf IV [ed: in Europe] and in the Passat 3B/3BG. Externally identical control units from VDO were also used in some of the same cars, which have the same pinouts, but whose Self-diagnosis channels are assigned differently. User beware! Reading the Internal Error Memory: Ignition ON. To activate the readout: Press and hold the „ECON“ and „Recirculate“ buttons simultaneuously for about 2 seconds. Any error codes present will now be displayed. To scroll to the next error code, press the „Warmer“ button. When all codes have been displayed, „000“ is displayed.

If there are no errors present, „444“ is displayed.

To clear the error codes: After the last code is displayed, (i.e. after „000“ is displayed), press and hold „ECON“ for at least 2 seconds. „444“ will be displayed as confirmation that there are no more codes present.

To exit the Internal Error Memory Mode: briefly press the „ECON“ button.

List of Possible Error Codes: (Error Code / Error Location / Error Type) FFFF Control Unit 0x25 0119 Vehicle Speed Sensor 0x25 0214 Supply Voltage 0x06, 0x07 021A Reference Votlage 0x06, 0x07 0510 Temperature Sensor – Dash Vent (1296) 0x1d, 0x1e 0511 Temperature Sensor – Footwell Vent (1297) 0x1d, 0x1e 030B Outside Temperature Sensor – Front Bumper 0x1d, 0x1e 0313 Temperature Sensor – Fresh Air Inlet 0x1d, 0x1e 0332 Temperature Sensor – Evaporator 0x1d, 0x1e 0333 Refrigerant Pressure Sensor 0318 Air Conditioner Pressure Switch 0x23 031D Photosensor for Sunlight Intensity 0x1d, 0x1e 0382 Compressor Valve 04F7 Temperature Flap Servo Motor 0x25 04F8 Central Flap Servo Motor 0x25 04F9 Fresh Air Blower 0x25 04FA Recirculation Flap Servo Motor 0x25 025B Footwell/Defrost Flap Servo Motor 0x25 04B6 Standing Time Signal 0x25 0538 CAN-Bus 0513 Gateway 053D Kombi 04AE Gateway Database Version 0414 Control Unit Not Coded 0x23 043F Basic Settings Not Accomplished 0x23 Actuator Test All components of the Climatonic system are exercised during this test.

Requirements: Ignition off, Motor off, Vehicle stopped, Battery voltage 15 < 15.5 V.

To begin the self-test routine, simultaneously press and hold „ECON“ and „Recirculate“ then turn on the iginition (do not start engine) while keeping the buttons pressed, and continue pressig the buttons for about 2 seconds more. All LCD segments in the Climatronic display will now illuminate.

During the following automatic actuator test (duration ~30 seconds), all actuators will be exercised in a serial fashion. In addition, all control unit inputs (Sensors, Motors, Servos, etc) will be checked that can be checked with th motor off. During the test all

buttons are disabled, and all LCD segments are black. Once initalized, the self-test cannot be interrupted via the control panel nor via VAG-COM. Upon completion of the test, the control unit automatically switches into „Internal Error Memory Mode“ (see above.)

To leave „Internal Error Memory Mode“, press the „ECON“ button.

On Board Diagnosis On Board Diagnosis (OBD) mode is available with/without the motor running and also while the vehicle is moving. To enter OBD mode, simultaneously press the „ECON“, „Colder“, and „Fan Speed Down“ buttons. Scroll through the diagnosis channels using the „Warmer“ and „Colder“ buttons. The climatronic will continue to operate in the mode it was in before OBD mode was entered (unless you don’t hit the buttons all simultaneously, in which event you may lower the temperature setting , fan speed, or go into Econ mode by accident... it requires a practiced touch to not do any of these things)

To exit OBD mode, press the „ECON“ button.

Note: There are different channel assignments, depending on the manufacturer. [ed: I believe only Hella units were installed on US-bound Passats, but I’m not 100% sure on that] If there is a plausible speed value in channel 16, then the following assignments apply. Other units have the speed on channel 17 or 19, in which case the following chart isn’t applicable.

Depending on the vehicle, all available channels may or may not be in use.

[ed: * below means I’m not 100% sure on the meaning of the channel label]

„Bit“ in the units column indicates the binary values 0=false, 1=true.

Notes on individual channels The vehicle speed displayed in Channel 16 is not extremely accurate, despite its digital display. It basically serves to regulate the amount of fresh air intake in proportion to the vehicle speed – no mor and no less. [ed: After comparing with my GPS speed, I’ve found the channel 16 speed on my car to read closer to actual than the speedometer, but it tends to err one or two mph slower than actual... use as a speedo at your own risk.]

The Channel 40 evaporator temperature can roughly establish whether the cooling power of the A/C is working optimally or not. Indepent of the possibly subjective perceptions of the inhabitants, this is an objective measure of the achieved evaporator temperature before later mixing with warmer air as necessary. Even in the hottest of temperatures, when set to „Lo“, the A/C should achieve an evaporator temperature in the neighborhood within minutes, and after at most a half hour of easy driving, should reach a steady state of 3 °C.

System Errors If a system error was detected during the last driving cycle, all the LCD segments will blink 2 times per second for 15 seconds after the ignition is turned on.

The following stationary errors will also set a system error: - VAG-Tester Function 04 - Basic Settings not performed. - VAG-Tester Function 07 - Parameter Coding not completed. - Exterior temperature sensor (Fresh Air Inlet and/or Bumper) defective. - Pressure switch/sensor defective. - Interior temperature sensor defective. - Reference voltage.

det ble mest rot ..... sjekk her mye info her

Ved test så fikk jeg opp feilkode 318

[Satanoperca]

Hei

vist du ser på denne lista ser det ut som det er en trykkføler (0318 Air Conditioner Pressure Switch )hvor den sitter aner jeg ikke...men du skal kunne trykke flere ganger til du får frem kun nuller i displayet .

Men om displayet bare "flasher" er det noe rart.

Heisann

Det var bare feilkode 0318 som kom fram og 0000

Ser den på lista ja, 0318 Air Conditioner Pressure Switch 0x23

så nå er det bare og håpe på at det er noen som vet hvor den trykk bryteren sitter da

 

Tusen takk for hjelpen så langt

[Mondeo]

Men er det da bryteren som er feil, eller er det for lite trykk i systemet?? Vet at den bryteren har vært et problem på noen "dekaltrimmede" VAG produkter med 1,9 TDI (Ford Galaxy) i allefall.

Men er det for lite kjølemedium i systemet vil den også slå ut pga lavt trykk

Sjekk om du har nok gass

Er det noen måte og gjøre det på selv eller må den på verksted

[Beinet1]

Jeg hadde samme symptomene ifjor når jeg kjørte rundt uten kompressor. Så jeg antar at flashende display betyr for lite gass eller ingen kompressor tilkoblet.

 

Et verksted vil helt sikkert at du skal foreta en re-fylling av systemet. Da tapper de uta alt du har og fyller på nytt. Er triks kan være å trykke ned sentertappen i påfyllingsventilene og se om du har trykk på systemet. Det skal være bra med trykk der.

[Blanklaks]

Får vel begynne og sjekke etter lekasje da, for det skal vel ikke minke så fort. Byttet kompressor for halvannet år siden og fylte opp igjen gass samtidig.

Hvordan er det enklest og finne lekasje da, med såpevann eller er det noe som er bedre og bruke?

Skal selfølgelig sjekke trykket på ventilene først

[Fartstripa]

du får svinge deg en tur ut til meg, så skal jeg trykteste og fylle opp for deg..
