I've driven crappy cars for years and finally treated myself to a lovely 2003 A3 TDI Auto 1968CC 3 door with only 53K on the clock - lovely car!
Been driving it around for 1 month just fine.
Today, at speed on the motorway, I had a sudden loss of power. Couldn't get it over 60mph or 4,000 revs, or to any lower gear than 4th. No amount of accelerator pedal pressure made any difference to the car.
When I stopped at the next service station, turned off the ignition then turned it back on again, all was fine until I reached 70mph (usual power, usual response etc) then the problem returned.
When I finally got to the North Circular Road, the car was fine and lovely and responsive so long as I kept below 60mph. Over 60mph and the car lost all power again.
At no point did any warning lights come on, any odd noises or any fumes. However, at low speeds, I noticed the MPG was reading upto 200MPG. Does that help isolate the fault?
I am completely new to this forum and to the joys of owning a lovely car. I am also broke (having just bought this baby). Don't want to just walk into an Audi service area without some sort of knowledge as to what the fault may be and how much I may be expected to pay for it.
I thought I'd ask here as you guys know what you're talking about and I don't! Any suggestions???
