If the Check engine warning light, and or flashing glowplug illuminates on your Audi A6, it can be frustrating, and worrying, but it might not cost as much as you think to replace, and it can also be done at home, on your driveway, without it costing a lot to be repaired at the local garage.
In this real world example, the vehicle (an Audi A6 C7 from 2016) started with a flashing glowplug light. The next day, the check engine light also illuminated with the flashing glowplug light, and the vehicle went into limp mode, with restricted performance.
The iCarsoft VAWS V3.0 was used to diagnose the fault, the fault code & description was was P023700 Turbocharger Boost Sensor (A) circ.- Low Input
With this information, it was deemed that the MAP sensor (or boost sensor) was faulty, and needed to be replaced. The part number was 04L 906 051 C, and a replacement was ordered from the Audi dealership shich cost £92. The new part Audi supplied was 04L 906 051 K (notice the end letter was a K and not a C) this is the newer updated part but fits exactly like the original.
Once the replacement sensor was installed, the engine was started and the gloplug light was no longer flashing, but the check engine light was still illuminated. Again, the VAWS V3.0 tool was used, this time instead of diagnosing the fault code, it was used to erase the fault code, which removed the car from limp mode/restricted performance, and turned off the check engine light.
The video below outlines all of this, so just follow it through step by step, and if this is helpful, you can buy the VAWS V3.0 directly from Diagnostic World via the link above.
