I've read about it on some forums and I don't like relying on the MMI. Just yesterday I had an oil light warning so I added 500ml of oil and also had a 'health inspection' from Audi the next day. They told me the car's oil was full, but I didn't see how that was possible since the light came up and I only added 500ml of oil. I got home and my oil level was reading 'ok', so really, either Audi mehanics don't know how to correctly read gauges or this MMI oil reading thing is a load of garbage. I wanted to know if it's possible to install one. I heard that this is the Oil Dipstick's number: '06J 115 611 E' but just wanted to clarify if you can and if it's the correct one. Also, I wanted to know if there's any UK sellers that may sell this part. Many thanks.
