Ne, su varikliu viskas gerai, tik diagnostika rode ta pasildytuva ir pastebejau kad ilgokai syla iki darbines temperaturos. Cia rase kad tas sildytuvas keleivio pusej prie stiklo, bet pas mane ten nera jo.

tema apie apsuku svyravima, o tai gali buti del apkrovos nelaikymo, o E46 vanos man rodos apkrovai taip pat itakos turi.

Na pas mane su apsukom viskas gerai, bet kaip matai kalba pakrypo apie ta elektrini sildytuva, taigi ir as parasiau

Electric Auxiliary Heater DDE 4.0 (E46 only)
The electric auxiliary heater heats the coolant with electric heating elements to compensate for the slight heat loss at high degrees of engine efficiency. Depending on the vehicle equipment, the heating request is sent either from the air conditioning system (IHKA) or from the heating control to the DDE control unit.

The heating elements only cut in when there are sufficient electrical power reserves. To determine the available power reserves, the alternator sends a pulse duty factor signal corresponding to the current alternator load to the DDE control unit. Depending on the permitted additional alternator load, the DDE control unit activates the auxiliary heater with a square-wave signal with pulse duty factors (= variable pulse widths) between 5 and 95%, thus controlling various heating power stages.

The idle speed is increased to 850 rpm when the auxiliary heater is activated.

Cutout conditions
The auxiliary heater is switched off under the following operating conditions:

•Battery voltage < 12 V (ON hysteresis 12.8 V)

•Engine speed < 710 rpm (ON hysteresis 730 rpm)

•Time after engine start < 10 s


•Coolant temperature
The coolant temperature threshold that must be exceeded for the auxiliary heater to cut out is determined with the measured ambient temperature from a characteristic curve. Characteristic curve data:

Ambient temperature [°C]
Coolant temperature threshold [°C]

-10.0
86.0

-5.0
86.0

10.0
50.0

20.0
17.0


Important: A fixed coolant temperature threshold of 86°C applies if no outside temperature sensor is fitted.

The outside temperature sensor is fitted in the following E46 models:

•On all models with 6-cylinder engines

•On models with 4-cylinder engines only with on-board computer or air conditioning.


The auxiliary heater is also switched off when one of the following fault codes is stored:

•0115, ”Coolant temperature sensor”

•1A04, ”Electric auxiliary heater”

•1A0E, ”Alternator load signal”

Troubleshooting
The activation function is monitored for short-circuit and open circuit.

As from DDE software version B1 (phase-in 07/2000) the auxiliary heater will be monitored for overheating.

Fault code 1A04 ”electric auxiliary heater” is stored if a defect occurs.

Consequence: Poor heating capacity at low temperatures

If the alternator indicates a load signal of 0 %, fault code 1A0E ”Alternator load signal” is stored.

Consequence: Auxiliary heater is switched off

Pas mane irgi apsukos sokineja. Kol heateris veikia, stovi auksciau, kai heateris neveikia krenta zemyn

bet jei variklio temp kyla labai ilgai, cia susija su tuo? ar termostatas visgi?
Toks pats extra heateris stovi ir kitoje vietoje , padarysiu foto rytoj.

Jei heateris veikia gerai, ir vis tiek ilgai syla variklis, tai manyciau gali buti ir termostatas. Bet jei heateris veikia blogai, tai prie saltesniu oru variklis tikrai syla ilgeliau
Pas E46 tas heateris stovi desnej pusej, tarp variklio ir amortizatoriaus stakano. Netoli tepalo matuokles visai

As ir paziurejau, prie pat tepalo matuokles

koks ezio detales kodas? kas pagelbet galit?

Su tuo pulsavimu, del to "pasildytuvo" isprendziau reikala, paprasciausias dalykas istraukt is jo fiskute su plonais laidais ir apsuku sokinejimai baigesi..

tai kaip tu ja isprendei????? fiske istraukt visi galim,bet su istraukta fiske variklis daug ilgiau syla,geriau sakyk ka daryt kad greit variklis pasiltu ir apsukos nepulsuotu,gal kas remontavot ta papildoma sildytuva?

Ar atradot kas nors? koki nors problemos sprendimo buda? ar su atjungtom fishkem vazinejat?

tai va taip ir yra pas mane, sukyla iki tų 850, tai pagal aprašymą taip išeina jog HEATERIS veikia... bet tada kodėl metą klaidą diagnostikoj ? šiaip variklio šilimo laiku tikrai nesiskundžiu ..

per kiek laiko (ar km) mazdaug tau ryte uzvedus salta varikli pasyla iki darbines temp?

na kaip tau čia pasakius: pilnai iki 88C, įšyla taip grubiai sakant ~10km, dėl laiko tai įvairiai, nes vieną kart tuos dešimt km nuvažiuoji per 5min, kitą per 30min. čia +- prie dabartinių orų.
kuo daugiau šviesoforų, tuo daugiau apsukų, tuo greičiau ir sušyla man atrodo

pas mane panasiai, nezinia ar cia skaitosi greitai ar letai uzsyla, gal yra kam greiciau pasiekia darbine temp?
