Aparently the audi r8 has a similar oil level sensor like the a2 1.2 tdi any.   The r8 number: 420907660  The 1.2 oem no is: 045907660B   The r8 version seems cheaper and more available than the a2 version. Usually it is around 40 -50 euros cheaper.    Did anyone try this?   (I cannot fix mine - the soldering did not do the trick)   Thanks for the info on the forum. It is very useful.   german - google translate:
