DSG Gearbox Problems & Common Faults

The DSG gearbox brings together the ease of an automatic gearbox with the simplicity of a manual gearbox BUT like all things mechanical they do have some problems and will need service and or repair sooner or later. Common issues you can expect to see include:

  • Bad gear selection/stuck in gear/no gear selection
  • Error messages on the dash
  • Vibration and knocking sensations
  • Worrying noises

All of these DSG issues are common or known faults to us here at CCM and sadly, will all lead to the eventual failure of the DSG gearbox or its functions. Don’t worry though, as everything is repairable.

Let’s break down the most common issues into two headlines groups and we’ll expand on each issue further down the page:

DSG Gearbox Issue 1 – Car Still Drives

If your car is still driveable then give us a call and book in for a diagnostic report. This will allow us to advise on the precise fault and provide you with a detailed repair cost. You can then leave your car with us and use a free courtesy car, or schedule a repair for the future.

DSG Gearbox Issue 2 – The Car Won’t Drive

Your car won’t move when put into gear or commonly won’t even select a gear so your car is stuck.

Get a recovery plan sorted to bring the car to us and if you need a loan car then grab a lift with the lorry and we will reserve a car for you. Once your car is with us, we can get stuck into the diagnosis and provide you with a quote for the work needed.

Give us a call to book an appraisal, or complete an online enquiry and we will get back to you as soon as we possibly can.

Main Causes of DSG Issues

Major Cause No.1 –  DSG Clutch Issue

Your DSG gearbox has two clutch packs, one for the odd-numbered gears and one for the even-numbered gears. If either clutch pack fails or is worn you will have issues. Basically, just like a normal gearbox, you need a new clutch.

The problem is that these clutches are not quite as simple as a standard gearbox and require specialist equipment and knowledge to fit them. Plus specialist equipment to program and adapt the new clutch.

On smaller engine cars these DSG clutches are dry clutches with an estimated range of 60 – 70,000 miles. On larger engine cars the DSG gearbox clutches are ‘wet’ which means they live in an oil-based environment. This does improve the clutch wear but creates a problem with contaminated oil. If your car is a 2 litre or above then the DSG clutch oil should be serviced regularly.

Call CCM and book in a fixed price full diagnostic as you don’t want to be rushing into a clutch kit if that is not really the problem.

Major Cause No.2 – Failed Mechatronics Unit

Your gear selection is handled by an electrohydraulic robot called a mechatronics unit.

Mechatronics units fail pretty much as often as the clutches so they are a common failure. The mechatronics units are replaceable, but just like the clutch, we need to be sure which part has failed.

Give us a call to book a diagnostic slot, or complete an online enquiry and we will get back to you as soon as we possibly can.
