My Audi A4 is stuck in first gear. It only has 50,000 miles on it and all maintenance is up to date. After looking online, many owners say it is a common issue with the A4 and is related to a brake light, or brake sensor issue.
Your transmission needs a vehicle speed sensor signal in order for it to shift. A bad sensor may be the cause of your problem and would need to be properly diagnosed by a qualified mechanic to scan for codes in the engine and transmission along with the antilock brake system.
