Driving home this morning my Golf TDI slowed speed seemingly in first or second gear. I couldn't change gears using paddles or manual shifting on gearstick. the car is automatic. And then there was a yellow diagonal wrench flashing, located in the space of the instrument cluster where the gear selected appears. So, in lieu of a D I had an intermittently flashing yellow wrench, which, I kid you not, in the manual, or anywhere online I cannot find to clip to show to you. The warning is unable to be found so far anywhere. Drove about 2 miles home at about 25 mph, keeping RPMs around 2000. Arriving home I couldn't put the car in reverse. Drove around the block to find somewhere to park that didn't require reverse. Turned car off, waited a few moments, turned on, reverse worked, wrench gone. OK, few q's: 1) from my rudimentary research this is limp mode. Presuming a problem, do I have enough functionality to drive 7 miles to my former dealer/repair place or should I just go 4 blocks to good repair shop, but not a dealer? 2) Why can't I find this icon anywhere? I bought a "technicians car" that he had customized for himself as part of the deal to come work in US for a period of time. Is that why? Is it a German-based warning indicator? 3) I just needed to install a new battery which I found odd after only 5 years. OK, was told I needed new vents in two places and decided to have oil change done at non-dealer repair place. Also needed to have car towed there initially. Could any of these impacted the car to produce a warning like this? Evidently we don't know what this is yet, but ideas? 4) Any estimate of what this may be? Again, no other warning lights were on, no numbers, nothing except the wrench above the D sign indicating Drive. Thanks in advance for any help.
