Audi q7 3.0tdi 233hp no power
Hi,
In the Q7 that my friend bought, something is clearly wrong from the beginning. The car apparently stood for a long time, and after the purchase a few things were taken care of: - egr - intake manifold flaps - turbocharger regeneration - exhaust gas temperature sensor - of course, all fluids, filters and engine oil. Currently, the engine runs very nice and smooth at idle. At low speeds around town it drives quite well, but the problem occurs when accelerating hard. Up to 100 km/h or 2200 rpm, the car pulls well considering its power, but around 100 km/h, when the revs exceed 2200 rpm, something clearly cuts off the power and then the acceleration is practically zero, there is a complete lack of power. I will add that I noticed that when the gas pedal is pressed gradually, gently and evenly, the engine "accelerates" and has power, but when the gas pedal is pressed violently to the board, as soon as we approach the mentioned ~100 km/h, we achieve around 2000 rpm you can immediately feel the power cut off, and the engine's operation can be compared to a vacuum cleaner. Later driving and reaching, for example, 140 km/h takes almost forever. Currently, there are no errors in the engine, the only thing I noticed when checking Audi with VCDS was error 01314 in the CAN module - engine controller. I post a photo below. I will be grateful for any hint that will help in diagnosing the problem. I guess it would be good to make logs, but I won't have access to the car in the next few days, so that's why I thought to ask you for now, maybe someone has encountered something similar. |
