Oil level dipstick measurement on Audi R8 4.2 FSi

I have heard the correct transmission oil level can only be measured with diagnostic equipment and the dipstick is used as a rough check during the initial fill.
Not sure where the plug is to remove to use the temporary dipstick.

Checking the pump Oil Level:
1. Verify that the compressor is turned off and on a level surface.
2. Remove oil fill plug - Add until oil reaches "MAX" oil notch in oil fill plug

you measure the trans level by pulling the trans dipstick with the car warmed up (after a short drive), on level ground, engine running-it should read within the 'hash marks' on the dipstick to be considered correct

The yellow light oil sensor on Audi TT Quattro is the warning message for the minimum oil level has been reached !!!
Check engine oil level by dipstick & fill up oil inside engine !!!

you should always use the recommended oil. the viscosity of the oil is critical to bearing lubrication. as for quantity, after draining oil and replacing the filter, fill the crankcase with 4 quarts. this will be enough to provide protection. run the engine for a minute or two. shut the engine off and allow 2-3 minutes for the oil to drain back into the crankcase. check the oil level. if the oil is visable on the dipstick to the bottom of the hash marks, add 1 more quart and that should bring you up to the full mark. the area of the hash marks represent 1 quart. if the oil is at the half way point between the hash marks, add 1/2 quart. the dipstick might also have sight holes where you read the level. in any case, the marked area measures 1 quart. if the oil falls within those marks, add the proper amount accordingly.

Drain the crankcase oil into a clean container in which you are able to measure the amount. Replenish this amount up to the quantity stated in your hand book. Remove dipstick and fill the crancase with just this oil. Dip the oil level and using a scriber or a file, mark the dipstick at the level of the oil.
Notes:
1. The quanity of oil is the engine capaity less the oil filter.
2. You may wish to use clean new oil and fit a new filter. If so, use the fill capacity including the oil filter, or add about another pint.

Have you verified that the power steering fluid is at the right level? If it isn't, you need to fill it to the proper level using specific Audi power steering fluid (it's a mineral-oil-like fluid, NOT the stuff you buy at the parts store). If you've run the reservoir dry and kept driving, it's likely you've burned out the pump and will have to replace it.

If the oil's full the problem is in the sensor and a mechanic can repair the problem. If the oil level is low, change or fill the oil and the light should go off. If you've never done an oil change yourself you may want to have assistance as it can be tricky. When you check the oil and the level is at the "add" line you will add one (1) quart of oil only. If it's not registering on the dipstick you'll need to add two (2) quarts, check the level after several minutes and add accordingly. JiffyLube does good work and will save you the headache of labor. Good luck to you

It is a problem with engine oil level. This can affect EPC light. NEVER you must fill up engine oil above the "max" mark of the oil dipstick !!! If oil level is above "max" there is risk of damage to Three Way Catalitic Converter !!! You must bring oil level at "max" mark of dipstick, but under no condition above !!!

sounds like low oil pressure
