I have a problem with my Audi A6 Turbo. I am seeing the Oil temperature Gauge high. I am still driving after the dealer said it is normal in CA. ( Oil Temparature goes close to 230 F ) . I am seeing slowly after a couole of weeks the car gets rough and I have to acclrate moe than normal.
Dont know if the transmission needs a check or oil temp is the problem or any other rotating part . Feel like something is holding to car and I accelerate mor than normal and that intial smoothness when i hit the gas is lost.
Can anu one help me nail down where the probl could be .

I am going to say 'blown turbo'. As I understand it, they needs replacing every few years. They are susceptible to heat and incredible revolutions. They have to be lubricated, the seals go, and you get smoke.
I would check the thermostat first. Remove the thermostat and place it in a pan of water on the stove. Place a thermometer in the water with the thermostat and slowly increase the temperature until you have reached 194 degrees Fahrenheit or 90 degrees Celsius. Watch closely for the thermostat to open slightly. If it opens then the thermostat is good. If it does not open, replace it. Try that first and see what you come up with.
have you checked your fuses start up under the dash on drivers side if the fuses r good then check the fuse panel under the hood. I never worked on an audi but most cars have fuses in both spots nowadays . least exspensive solution to try before you get into the exspensive steps
Same here....I soon had the same problem after changing the oil..Found out after many tests and research that auto parts stores cross reference a lot of audi oil filters to the vw counterparts..Which do fit audi,but are shorter and lack the oil capacity to feed the engine.Then the pressure light pops on!!!! make sure the larger/longer oe type is installed.If your not sure buy it from audi its not much more than the napa brand.
Sound's like a bad alternator, you can check the alternator by measuring the voltage on the battery when the car is started, it should measure above 12.6 volt's but not higher than 14.5 volt's, check the drive belt tension, a lose or wore drive-belt could cause problem's with the alternator charging the batery, check the battery terminal's for corrosion, along with the connection's of the battery cable's.
Hope this help's, good luck.
The guage and fan speeds work on independant sensors. If you can remove the plastic engine cover and locate the "sending unit" for the gauge disconnect it and restart the engine. The gauge should remain cold and not move. If this is the case replace the sending unit. This should be a single wire sender located in the waterjacket of the intake manifold look in the area where the upper rad hose enters the intake.
