Nu stiu nici eu ...dar nu cred ca poti face treaba asta ca este tractiune 4x4 permanenta.

**SergiuMB** · 03-04-2008, 22:24 PM

Nu poti opri tractiunea integrala..este permanenta

**orca** · 03-04-2008, 22:25 PM

Am dat si eu ceva telefoane sa intreb, ca habar nu am, si mi sa spus ca eventual poate prin soft, altfel nu. Cica impreuna cu 4matic-ul lucreaza mai multe sisteme, diferentiale, cutie viteze, ABS, ASR, ASD, Tempomatul, etc., iar daca ar fi fost posibila scoaterea 4matic-ului fara a afecta masina, ar fi avut montat pe bord un comutator de catre constructor.

are in zona bateriei un comutator cu test 4matic.are si in carte niste instructiuni ,dar ma uit ca vitelul la masina noua ca nu inteleg o boaba frantuzeste.

un lucru pot spune pana acum. 4matic nu e masina de autostrada

am gasit asta pe wikipedia in legatura cu 4Matic, poate gasiti ceva ce va intereseaza

4Matic is the name of a four-wheel drive system developed and used by Mercedes-Benz. It is good for driving through slippery terrain.

Almost all their vehicles featuring this system also have an automatic transmission in standard equipment (except 260 and 300 gasoline and aspirated 300 D were standard with manual transmission) and that's where its name is derived from (4-wheel drive and automatic). The first design of 4Matic (or 4Matic) system was introduced in 1986 on the W124 series (E Class) saloons (four door) and estate (station wagon) cars. It was available with the 2.6 L and 3.0 L 6 cylinder petrol (gasoline) and diesel engines.

A complex electronically controlled system with automatically engaging four-wheel drive (4WD), the system employs locking central and rear differentials to provide additional traction in slippery conditions. The centre differential, also known as the transfer case, contains two clutches. Each hydraulically enabled clutch is controlled separately to allow for four modes of operation; 2WD (mode 0) where 100% of available torque is available to the rear axle, while the front axle is disconnected and three 4WD modes which allowed for 35% front/65% rear axle torque split (mode 1) or 50% front axle/50% rear axle torque split (mode 2). The rear differential, previously known as ASD on Mercedes-Benz models, can also be locked if rear wheel slip is still present while in the 50/50 4WD mode (mode 3). The 4Matic system uses inputs from the three channel ABS system and a steering wheel angle sensor to decide when to intervene. 4WD is disengaged automatically if the ABS brakes were applied. Two W124 variants of the 4Matic system were produced, the first system (1986-1991) used a mechanical pressure test lever to disable the system hydraulically while the second system variant (1992/1993) used an electrical test switch to break power to the system. The latter system variant when in test mode allows for continued operation of the rear shock self-levelling-system (SLS) when installed. Plagued with reliability problems at first, the multiplate clutch central differential were prone to failure -- Ritter, S: Mercedes-Benz E class Owners Bible Problems Section page 314 Bentley Publishers 2007 ; it was withdrawn in 1993.

The four wheel drive system was developed in conjunction with Steyr-Daimler-Puch, who manufactured the Mercedes-Benz G-Class in Austria. The second generation of 4Matic was re-introduced on the W210 series in 1998/1999. Available only in left hand drive the cars were again manufactured at the Magna-Steyr plant in Austria. The second generation of 4Matic used a full time 4 wheel drive system with three open differentials front, centre and rear. Traction control is achieved using ETS (Electronic Traction System). This employs the ABS system with additional valves to monitor and then partially brake any wheel which loses traction. This much simpler system is also used in the Mercedes-Benz M-Class SUV.

The 4Matic system is currently available on the E-Class, C-Class, R-Class, S-Class, Viano and the entire Mercedes-Benz SUV range.

Mercedes-Benz W124 Owners Manual
-----------------------------------------------------------
page 71.

Automatically Engaging Four-whell Drive (4MATIC)

When the key is in steering lock position 2 the yellow operation indicator lamp in the speedometer and the yellow 4MATIC indicator lamp come on and must go on when the engine is running.

The operation indicator lamp comes on while driving when the front whel drive or the front wheel drive and the diferential lock(s) are engaged.

Front wheel drive and differential locks engage automatically as soon as one or more wheels start slipping (difference between speeads of front and rear wheels) because of road conditions or driving style.

When the operation indicator lamp comes on the driver is informed that the tires have reached their adhesion limit.

The driving style must always be adapted to to the road conditions, even if the vehicle is equipped with 4MATIC.

Notes :

If the 4MATIC indicator lamp comes on (possibly at the same time as the operation indicator lamp) while the engine is running, this indicates a fault. In this case, turn service switch on the right-hand side of the engine compartiment to the stop in position 2. The vehicle will then be driven by the rear axle only.

On vehicles equipped with level control this system is deactivated if the service switch is in position 2.

A fawlty 4MATIC system should be checked at a MERCEDES-BENZ service as soon as possible.

Before the vehicle is driven on chassis dynamometers the service switch must be turned to position 2. The 4MATIC indicator lamp comes on and only goes out again when the service switch is turned to position 1. A maximum testing time of 15 minutes on the dynamometer must not be exceeded.

If the service switch is in position 2, the level control is deactivated.

When towing the vehicle, comply with instruction on page 93.

Service switch
1 - Operating position
2 - Test position
-------------------------------------------------------------
page 93.

Vehicles Equipped with 4MATIC

If the veficle is towed with the front or rear axle raised, do not exceed a speed of 50 km/h or a distance of 50 km. Move service switch to position 2.

If the vehicle is to be towed over a long distance with the front axle raised, unflange the propeller shaft at the rear axle, if the rear axle is raised, unflange the propller shaft at the front axle.

Felicitari de achizitie, ca n-am apucat s-o zic.
De ce zici ca nu este masina de autostrada ?, eu in 1988 am condus un W124_300TE_4MATIC, si pot sa sa-ti spun ca alergam usor cu ea 200-220 km/h.

**300zxtt** · 03-05-2008, 08:51 AM

pe autostrada dupa 120 incepe sa sa-i creasca brusc consumul.am mers pe autostrada soarelui o perioada cu 170-180 si cand am vazut cum scade acul litrometului pe moment am crezut ca ma aflu la volanul unui G-clase cu motor V8.sa vedem cum o sa se comporte masina la iarna....

raman la concluzia ca pt drum lung tot e320 ramane solutia ideala.

mersi pt urari....deja au inceput problemele aici.bulgarii au o lege ce cam limiteaza masinile peste 120Kw.dupa aceasta cifra se plateste o acciza imensa.pt 132kw cat are aceasta masina trebuiesc platite in jur de 2500E.

sa vedem cum o sa o rezolvam....

**DMIHNEA** · 03-05-2008, 15:20 PM

4 matic de pe w124 e foarte complex si sensibil,pe w210 se puse mult simplificat(vezi pe wikipedia).Io sunt in negocieri ptr w210 motor cu cilindrii in v(nu in linie)full,pe gustul meu....w124 e super gurmand cu 4 matic...

Ca sa nu citesti prin km intregi de documentatie, iti zic eu intr-o fraza ca masina merge in mod normal 2x4 si daca simte ca nu are tractiune transfera ceva gen 40% si la rotile din fata. Deci nu este 4x 4 permanent, ori s-a blocat ceva si a ramas asa ori consumul mare se trage de la altceva.

acum am pbservat ca trage numai spatele si in caz de necesitate trage si fata.consumul mare e pe autostrada la viteze mari.E320 era mult mai rapid si consuma in jur de 11-12 pe autostrada la viteze maricele.asta trece de 14 in acelasi stil.dar in curbe si carosabil alunecos se simte cum intervine 4matic.indiferent de pozitia pedalei de acceleratie,masina nu derapeaza deloc si pastreaza traiectoria impusa.nu are aceasi manevrabilitate precum un w124 normal datorita razei mai mari de bracare.

p.s. orca,shadow mersi pt informatii

**paunionutz** · 03-05-2008, 17:37 PM

eu am vazut la mai multe bmw-uri care erau 4x4 ca le scoteau planetarele de pe fata din cauza consumului. acu sa nu-mi sariti in cap ca la 124 nu stiu daca se poate sau nu, dar la ursulet sigur se poate

**claudio** · 03-05-2008, 17:47 PM

felicitari

sa ne tii la curent cu inmatricularea in bulgaria.

**asfalttango** · 03-05-2008, 21:42 PM

Te astept sa o vedem si noi pe nisipul de pe plaja...

**300zxtt** · 03-06-2008, 02:44 AM

trebuie platita acea taxa sau inmatriculata masina pe un handicapat....

atasez poze cu masina facute in bulgaria
