Title: Dreaded - Gearbox Malfunction - you can continue driving - Error in Dash
Post by: Al1040 on 02 June 2026, 15:03
Coming back from Manchester early evening last Friday in the warm weather I had the error above come up on the dash and lost odd number gears  :sad:
Managed to get home but it did get progressivley worse.

I Manged to pull the code with my OBD11 and it was P173500 (Position Sensor for Clutch 1 Electrical Malfunction).

I have done a bit of ringing around and it looks to be in the region of 2k if the Mechatronic unit needs replacing which is highly likely. There is of course a TSP for the fault in the UK but unlike US, Aus etc VW have not put out a recall!!

Another option would be to send the unit away for refurbishment for c. £400 but of course would require removing etc.

What are the thoughts of our esteemed members on the best way forward?

Thanks in advance.

Car currently has c.83k, DQ381 7 speed.
I manged to clear the fault and had a quick drive and it has not reoccured.
