New fault indication has started on my Mk6 Golf CC GT (2012, 29K miles). The indicator showing DSG mode (D, S or P) and gear number, flashes alternately with a spanner symbol. This happens after the engine has fully warmed up and doesn't go away until it has fully cooled down after stopping the engine. It happens in any driving mode and regardless of load on the engine. No info on this sort of warning in the handbook and VW dealer seems clueless - "Book it in and we'll have a look at it." Does anyone have any idea what the problem might be and what the solution is?

It could just need an update, or there was a failure when it went to shift into
that gear. There are shift fork position sensors, and if the one for that gear
isn't signaling properly, then can happen. You can take it in, but do not
authorize any repairs. All I have seen with this issue was a software
update fix.

Hi, I have 2012 VW polo, I noticed this same thing happening last night. There doesn’t seem to be an issue with the car (as in it sounds fine) but I’m concerned it will do damage if I keep driving it like this? Did we end up figuring out what this signal means? Thanks

Flashing spanner means your transmission control module logged some static or intermittent errors. Before making any conclusions you will need to read those TCM errors either with VCDS or OBDeleven or any other solution capable to read vag's transmission module. More likely you will see some hydraulic pressure related errors which will most likely lead to mechatronic unit replacement. dont ignore flashing spanner go to diagnostic asap

Its the mechatronic. A sensitive DSG gear shifter in automatic Audis and VWs.

Its been a common issue with DSG and about time they set a recall for the vehicles with this issue and fix it free of charge.
It costs around $3k AUD to replace the mechatronic. Its risky to drive the vehicles with spanner blinking in the dash. Could breakdown anywhere.

I'd rather sell it back to VW.
