Information about rebuild transmission DSG-7 DL501 0B5 South-Tronic Audi

VAG DL501\ 0B5

Since 2008 launched seven-staged direct-shift gearbox of DSG7 of longitudinal arrangement with «wet» type double-clutch on the Audi Q5-Q7, A4 Allroad, A5 Cabriolet, A6-A7 — DL501. Thus, is an expensive heavy box of longitudinal organisation (DL — Dual\Longitudal) on which accept not-stingy details (> 140 kg) to guarantee the minimum resource before the first overhaul over 150-200 thousand km.

On VAG classification — OB5. It is aggregated with engines to V8 4.0l (diesel) and information technology is calculated on the drive upwards to 500 nanometers of torque on limit turns. But also, as well as in other DSG (Direkt Schalt Getrieb), the computer considerably limits the maximum moment transferred by the motor toward manual.

The gearbox is structurally divided into 2 compartments — «mechanical» where hypoid oil for mechanical gearboxes and «automated» compartment with friction clutches of the double-clutch is used. And also, the hydro block where special intellectual oil for DL501 — G 052,529 A2 is used. For cooling of ATF, the special #471 solenoid coil working instead of the thermostatically controlled sleeping room.

Oil in «automatic» compartment (7l) is changed with filters (external and internal) and cleaning of magnets of the pan subsequently 60 thou km of driving. If there is a desire to delay overhaul on 150-200 thousand km, then it is necessary to change the oil. Especially it concerns ageing gearboxes. Check of level and quality of the oil is fabricated on jellied bore at a certain temperature (38°C) with the use of the diagnostic equipment. It is amend to practise it by means of menders of DSG having feel and the corresponding equipment for adaptation. This gearbox is pretty reliable. Therefore, timely change of oil and accurate driving without extreme loadings and overheating allow to delay planned overhaul for 250 thousand km. Later on timely and full overhaul with replacement of all consumables (overhaul kit), this Direct Shift Gearbox will easily serve some more years.

Manual DL501 (0B5) Problems

Shavings from drum impairment both to filter and details in the gearbox, and the electrician — mechatronics, to solenoid coils and sensors. The partition with cleaning is recommended as soon as magnets of the pan show that hedgehogs of shaving have grown to several millimeters.

Clutch Teardown and Repair

Raybestos Tech Tip (DIY)

If shaving has considerably damaged internal atmospheric condition strips and layer pads and the car has crossed the marking of 150 thousand km, order overhaul kit with of layer pads and sealing glands — for substitution. Ordered the German overhaul from Autoline brand, poor structure earlier, simply consisting of original sealing glands and rings. Now there are stereotyped overhaul kits from Transtec, Precision, ATOK more than often. Substitution of friction clutches of both packages of clutches is made past set. Friction clutches have asymmetrical flutes for oil flow-downwards for improvement of cooling and need the correct installation in the direction of rotation. Steel disks. The article of clothing of friction clutches even half conducts to problems in clutch work.

In DL501 (as well as other DSG) Mechatronics became as a first «child-disease».

Mechatronic DL501 DSG 7 0B5 Identification

DSG sawdust in the gearbox

Mechatronic's problems are caused by the fact that settings of the figurer allowed to overload the detail of drums by kick-downwards, which has got past inheritance from the automatic transmission. The cloth of clutch is structurally rather weak for the aggressive modes of dispersal. The run-out of details influences the operation of valves and thinly adjusted electricians Mechatronics. The producer of electronics fifty-fifty asks to protect Mechatronics at repair from static electricity, grounding menders hands' special bracelets. Information technology is most space engineering science. For repair, Mechatronics is used diverse overhaul kit of the hydro block.

Mechatronic Solenoids Scheme

Work of transmission of DL501 with metal shaving in oil results in fast clothing of solenoid coils. VFS (variable-force — the solenoid whorl with changeable stream) solenoid coils — electro pressure level regulators in C1-C2 packages of the platform of hydroplane — the first thing subjects to replacement.

These solenoid coils are used for inclusion of clutches both on DSG6/vii Volkswagen-Audi, and on Getrag by 6-staged «moisture» clutch of WD 6DCT450 for Ford and DCT470 for Mitsubishi. Solenoid coils are adjusted very thinly, this why their valve does not keep work in the muddied hot oil arriving from the double-clutch. Also, the solenoid coil of the principal pressure of VFS (interchanged with the oil cooling solenoid coil) —  is replaced also oftentimes.
