When your Audi's engine warning light comes on, it can be concerning. At GSR Garage in Telford, we use professional diagnostic equipment to quickly identify engine faults on all Audi models, including the A3, A4, and A6. One of the most common Audi engine issues we encounter is oil consumption on 2.0L TFSI engines. This problem typically presents with specific symptoms that our diagnostic scanners can identify immediately. Another frequent fault is multitronic CVT failure on front-wheel-drive models, which often triggers the engine management light and can cause noticeable performance issues. quattro rear differential oil seal leaks is also something we see regularly, particularly on older Audi models or those that have missed scheduled maintenance. AdBlue system faults on diesel models can be more serious and usually requires prompt attention to prevent further damage. radio and MMI screen failures is another issue that affects specific Audi engines and requires professional diagnosis. Warning signs to watch out for include: the engine management light illuminating, unusual knocking or rattling noises, loss of power during acceleration, excessive smoke from the exhaust, rough idling, and increased fuel consumption.
