DQ381 Mechatronic – Causing Tiguan DSG Gearbox Problems

Volkswagen Tiguan DQ381 Fault

The DSG DQ381 gearbox has been designed as a smaller and lighter version of the DQ500 which greatly improves fuel consumption and reduces CO2 emissions. Fitted to front and all-wheel drive vehicles on the MQB platform such as Audi A3, Skoda Superb, Seat Ateca and Volkswagen Golf. Although there is a marked improvement in reliability – there are still manufacturing and component defects that will disable the vehicle – most notably on the Volkswagen Tiguan DQ381 mechatronic.  

 

DQ381 mechatronic failure is extremely common. When this part fails symptoms will be caused such as missing odd gears, intermittent loss of gears, the vehicle going into limp mode and complete loss of all gears. When identifying the issue with diagnostic scan tools, fault codes will be stored for clutch position sensors, which can initially be cleared but will always return until the problem is resolved.

 

If you are experiencing these DQ381 Tiguan DSG gearbox problems, or other model, then you may have been told that you need to purchase an expensive replacement from manufacturer. The problem with this is that it will also require coding to your vehicle, at further expense, and due to the defects not being worked-out at factory level – any replacement is bound to fail in the exact same way and you’ll be stuck in the same position as before.

 

We have a better solution…

 

Our test and rebuild service is designed to break this circle, we’ll rebuild your DQ381 mechatronic and supply an unlimited mile Lifetime Warranty as standard. When we do this, we use higher rated components than originally installed so there's no chance of it failing again in the future. All of this will be done within 3-5 working days, without the need for reprogramming, so you can get back on the road as soon as possible.
