Gen 1 R-Tronic Gearbox (Yellow) Dash Warning

[GLYN S]

After a bit of a drive in Auto Mode,I often get a dash warning stating "Gearbox Malfunction---OK To Keep Driving" and the Gearbox immediately reverts to Manual Mode.

I then continue my journey with no obvious problems in Manual.(2008 4.2 R8 with 26,000mls)

Has anybody had a similar experience ?. Any ideas of cause/reason ?.Any ideas for sorting the problem.Any idea where the port for fault-reading can be found ?.

I am very much "lost". ANY HELP WOULD BE MUCH APPRECIATED.

I'd recommend a diagnostic check to see if any fault codes flag up? Think the obd port is under the driver side lower dash. It could be a gearbox module issue.  

What's the service history on the gearbox? 

As degrading oil can affect the gear changes.

You're welcome. The only Audi independent specialist in Leicestershire is Chapman's based in wigston. Not that I've ever used them.
