Audi 2001
Battery is 6 months old and car won't start if left for a day?

Lacking an SUV offering and looking to add more power to its Avant wagons, in 2001 Audi came out with the allroad quattro (was e.e. cummings part of the Audi marketing team?). Based on the A6 platform, it was wider with larger fender flares, more rounded styling, and roof rails. Offering all the benefits of an SUV, with more safety, better handling, and classier looks, the allroad was a station wagon for the modern family.
Offered only in one trim, the allroad came equipped with a 2.7-liter, bi-turbo V6 engine, rated at 250-hp and matched with a standard 6-speed manual transmission. A 5-speed Tiptronic auto/manual shift was optional. What gave the 2001 allroad its confidence on the road was a unique adaptive air suspension system with four settings that raised the suspension height anywhere from 5 inches (for maximum highway cruising) to 8.3 inches (for maximum offroading ground clearance). An automatic setting selected the best suspension for the road conditions. This meant the allroad was a great traveling car, capable of handling a variety of elements. The variable lift meant adjusted the allroad for better cornering and turning performance.
The cargo area was long, if not particularly deep, but split-folding seats allowed for a variety of people and cargo configurations. A rear-facing seat option included 3-point seatbelts. Wood and leather trim inside, plus power-adjustable seats with extra bolstering not available on the A6 assured maximum comfort. Various packages added heated seats, steering wheel-mounted controls, auto-dimming mirrors, memory settings for both front seats, a navigation system, and a solar sunroof that stored power to operate a fan while the car sat idle, to keep it cool in the sun.
By far the AWD technology and variable suspension is the highlight of the allroad quattro, impressing owners with its performance in snow and mud. The 2001 allroad is also liked for its styling, which adds class to the family wagon. The powerful engine and speedy performance, precise handling, and spacious interior are all praised. However, drivers are disappointed with the allroad's reliability and constantly having to deal with unknowledgeable mechanics and unhelpful dealers. Porr gas mileage, a slight turbo lag, and steering that seems too light for city driving are other complaints.
Battery is 6 months old and car won't start if left for a day?
After being informed by my h.u.m. That my battery voltage is low , i was cruising along and the car stalled . The engine would crank but no fuel was igniting apparently . The engine light went on indicating cat issues . The shop charged my battery and it started just fine after checking that the alternator charges . Is it possible for my car to stall because the battery voltage decreased during my 6 hour trip ?
i have a 2001 audi allroad 2.7T and in the morning it takes several attempts at turning over before it will start, if i touch the gas pedal it will stall, but after about 10 min of turning it over and over it will finally ideal and then the rest of the day its fine starts perfectly until the next morning. Then the same happens, I just replaced my fuel filter and that wasnt it, i replaced all my sparkplugs 6 months ago and there are no codes. Any ideas?
My car will not start there was a check engine light and the code was for O2 sensors. I have ordered all 4 of them. I also replaced the relay and was going to replace fuel pump but it is still working. Is there anything else that it could be
i need to know the correct wiring diagram for a a6 2001 wagon with no navigation
