e36 325 tds vedot uupuu...

[jones69]

Vaihdoin kaverille 325tds:ään kannen vanhan haljenneen tilalle. Tämän remontin jälkeen auto tuntuu laiskemmalta kuin ennen ja kulkeekin vain 160km/h... Käyntiin lähtee hyvin ja käy niinkuin pitääkin... Missä vika? ! :think Auto vuosimallia 1995

Taidamme tapella saman ongelman kanssa. Omani esiintyy ainoastaan kuumalla moottorilla startatessa... Öljyn lämpötila anturi? Ohessa on aiheesta lisää, tosin e39 tds koneen osalta lontoon murteella:

Injection quantity control
The injection quantity is controlled under all operating conditions on the basis of following variables:

Engine speed

Drawn-in air mass

Engine coolant temperature

Fuel temperature

Boost pressure

Atmospheric pressure

Start of injection

CAN-bus messages from the transmission control (AGS) and ASC

Current calibration settings: Full load limitation quantity, additive quantity, start quantity, engine control

unit pair (service functions)

The injection quantity (volume) is set in the distributor-type injection pump by means of the control slide valve
(volume control) in the fuel quantity actuator. The actuator sensor signals the actual position of the control
slide valve back to the DDE control unit.
Fault code 1 is stored if the actual position determined by the actuator sensor deviates too far from the actual
position calculated in the DDE control unit. For safety reasons, the fuel supply to the distributor-type injection
pump is then interrupted by means of the electric shut-off valve.

The injection quantity (volume) is limited:

At an engine coolant temperature greater than 107 o C (engine protection function)

At an engine oil temperature greater than 130 o C (engine protection function)

At an excessively high volume of black smoke

The injection quantity (volume) is increased:

At an engine coolant temperature less than 60 o C

When driving off (automatic transmission only)


The maximum injection quantity (volume) is limited to a substitute value of 33 mg/stroke (corresponds

approximately to a maximum speed of 190 km/h at full load) if the following faults are currently applicable:

Fault code 6: Exhaust gas recirculation control deviation

Fault code 10: Start of injection control deviation

Fault code 101: Boost pressure control deviation

Fault code 5: Needle movement sensor

Fault code 102: Control unit fault

A substitute value of 21 mg/stroke is still used for the DDE 2.2 control unit with the part numbers 2246541 and

2246616 (installed up to 5/96). This value further limits the maximum speed to approx. 140 km/h).
