Audi A S & Q Series 7 speed DSG transmission problems

AUDI-0B5-DSG-Mechatronics-Removal.JPG

Various Audi Models from 2010 on wards suffer from a VARIETY of symptoms of a faulty Automatic Transmission.

The 7 speed dual clutch automatic transmission known as the 0B5 unit, uses an internal mechatronics unit, components on this unit fail causing various problems. Loosing reverse gear or having it slip or shudder is a common issue. Using a diagnostic scan tool and live data information the internal components can be tested and checked. The internal dual clutch unit is common for failing causing internal gear selection problems also.

Known Symptoms of Failed Mechatronics Unit 

  • Loss or Intermittent Reverse Gear.
  • Engine Light due to Faulty Solenoids.
  • Engine Light due to Faulty Speed Sensors.
  • Rough Gear Shifts due to above faults.

Known Symptoms of Failed Dual Clutch Assembly

  • Loss of Gears normally Reverse and all even numbered gears.
  • Slipping or Shuddering of gears.
  • Mechanical Disengagement of gears causing Engine light.
  • Jolting of Gear Changes on up shifting and down shifting.

After diagnosis is complete we can determine the faulty components that need to be replaced. Using parts sourced directly from components manufactures rather than Audi spare parts we can carry out repairs rather than complete replacement of expensive components. Put simply rather than fitting a complete new mechatronics unit we can fit a new solenoids which could be a saving of 70% on the parts cost.

BMW 6L45 Mechatronics Repair Kit 24607623883

For a long time BMW have used General Motors automatic transmissions in various models.

One unit that seems popular is the GM 6L45E 6 Speed Automatic Transmission with integrated Mechatronics unit. Now this transmission is the little brother the 6L80E transmission commonly found in the Holden Commodores from 2006-ON. 

This design of the Automatic Transmission uses an internal Transmission Control Module and Solenoid Pack known as a Mechatronics. Like any transmission with solenoids they are known to have problems and require the mechatronics to be replaced due to the solenoids being part of and sealed in the mechatronics unit. One would think being of GM origins the replacement part would be cheap and interchangeable quite easy. Unfortunately this is not the case the unit is specifically designed for BMW software only and if you where to use a Holden Commodore unit the BMW software wont load.

Common SYMPTOMS of faulty units

  • Drive ability shifting complaints mainly around 2nd - 3rd gear up shifts and also 4th - 3rd gear downshifts. 
  • Communication codes between transmission control module, ABS module and engine control module.
  • Transmission Solenoids codes.

Replacement mechatronics Units

To purchase a replacement Mechatronic unit from the BMW dealer can be expensive. We source our replacement genuine units directly from the manufacture warehouse which we can then code to suit our vehicles.

Hyundai i30 soft, harsh & flaring gear shifts 4 speed automatic

Hyundai i30 2008 to 2012 - 4 Speed Automatic Transmissions with various shifting problems.

A common problem we see with the 4 speed Hyundai automatic transmissions is noticeably bad shift quality when vehicles reach 60,000 - 90,000 km's. Another sign of a problem is very dark transmission fluid which can be seen on the dip stick. 

The problem is located in the hydraulic brains of the automatic transmission which is called the valve body. The internal parts of this unit wear which require the valve body assembly to be replaced. We source new genuine units direct from Korea which also include the internal wiring harnesses. This can be a saving to our customers of 40-50% on parts if compared to purchasing locally.

Known Faulty Valve Body Unit Symptoms

  • Delay into Reverse Gear.
  • Flare/Soft Shift into 3rd Gear.
  • Large Flare on 4-3 Downshift when around 80kms.
  • Harsh Shifts into 2nd & 4th Gear.

A valve body replacement does not require a complete overhaul of the automatic transmission. The fluid will need to be flushed so the new valve body assembly can operate correctly. The transmission control module will also need the shift point adaptions reset using a factory quality scan tool.

Driveline Maintenance and are you accountable?

Colvoss-Blog.jpg

Customers often ask should they service their transmission and or change the oil in there differential/transfer case in their vehicle?

My answer is simple if you’re asking that question I recommend you to get it done. Now if you’re in the category of customer who just drops off your vehicle to your local mechanic and hope all recommend fluid changes are behind done most likely they are to the manufactures recommendations. However manufactures now label driveline components fill for life and this means dealer mechanics & regular independent shops won’t change any driveline fluids.

What is Fill For Life?

Fill for life is a term used in late model motor vehicles when it comes to driveline components. Now to use an example I’ll use a 6 speed automatic transmission in a 2008 BMW. Now BMW have a vehicle which requires a 6 speed transmission but BMW don’t manufacture transmissions. This is where ZF a driveline component manufacture is approached to supply BMW with driveline components. This is where the sales pitch starts for ZF to win and secure the contract to supply.

Transmission Manufacture

  • Can supply a sealed unit which is maintenance free during warranty period
  • Less warranty concerns due to untrained/qualified workmanship
  • Lower manufacturing costs of spare parts due to long jeopardy of units.
  • Increased unit production due to increased demand on long life units.

Vehicle Manufacture

  • A sealed unit which is maintenance free during warranty period
  • Minimal spare parts stock due to maintenance free unit.
  • Increased profits due to low cost units

Now for people who buy new vehicles and turn them over every 3-5 years this is all good news. This information it targeted to vehicle owners who plan to keep their vehicle more than 5 years and or who are the 2nd or 3rd owner of a late model vehicle.
