I have a 2007 Audi A6 with a 2.4 V6 petrol engine.
Last week I noticed that my car was misfiring and had difficulty responding to the gas pedal, especially when the engine was cold, and only when starting. Once the engine warmed up, everything seemed to work fine. However, I also noticed a significant increase in fuel consumption of 30% or more.
I replaced the fuel injectors, spark plugs and spark plugs. Although the starting problem improved slightly, the high fuel consumption remained the same. After extensive research and diagnostics, I scanned the car and found no data from the two throttle angle sensors. To save time, I ordered and installed a new throttle body, but the problem persisted.
I checked the fuses and relays and everything seems to be working. Honestly I'm stuck and have no idea what the problem could be.
Can anyone help? I'm willing to start troubleshooting from scratch if necessary.
