One non-electronic thing both lights have in common is the communal earth connection. It's nice if that is the cause (no real cost). You might be able to test it - use a patch lead from the battery's earth terminal (-) to a good earth point on one of the light clusters. If it then works you know that the cluster is NOT otherwise getting a good earth. Hope this helps. Mike

At the bottom of the automatic gearbox (tiptronic) you will find 2 threaded plugs on below surface. First (in front of the car) is for emptying, and second is for filling up. Tightening torque is 24 Nm.


Automatic Transmission Fluid (ATF) checking:
1. Requirements for check:
1.1. Vehicle standing on level surface.
1.2. Transmission must not be in fail-safe mode.
1.3. Shift lever in "P" position, parking brake applied.
1.4. Engine idling.
1.5. Air Conditioner and heater OFF.
1.6. ATF temperature must not exceed 104 Fahrenheit degree (40 Celsius degree) at start of test.
1.7. Only ATF with designation ESSO LT 71 141 may be used. Do not use any lubricant additives.
1.8. Automatic Transmission Fluid ATF - part number: G 052 162 A2 (1 liter wrapping)
1.9. An ATF level check when transmission oil temperature is too low results in overfilling, when too high results in underfilling.
2. CAUTION: Too much or too little ATF will affect the operation of the transmission. The ATF level must be checked at regular intervals.
3. The oil level is correct if a slight amount of oil runs out when ATF temperature is between 86 Fahrenheit degree (30 Celsius degree) and 113 F deg (45 C deg) (caused by increase of oil level when heated). For warmer climates, 122 F deg (50 C deg).
4. Hang filled ATF reservoir VAG 1924 as high as possible.
5. Shift lever in "P" position, engine running at idle.
6. Place oil drip pan under transmission oil pan.
7. Remove ATF filler plug (at the bottom of the automatic gearbox you will find 2 threaded plugs on below surface. First (in front of the car) is for emptying, and second is for filling up.
8. With ATF temperature between 86 Fahrenheit degree (30 Celsius degree) and 113 F deg (45 C deg), for warmer climates, 122 F deg (50 C deg), a slight amount of oil will flow from filler hole when ATF level is correct.
9. If necessary drain or top off ATF to attain correct oil level. Top ATF with filler hook from VAG 1924 ATF reservoir. Insert VAG 1924 (tool) ATF reservoir filler hook into filler hole and top off until a slight amount of oil flows from filler hole.
NOTE: Fit filler hook into one of the oil deflector cap slots placed on the filler opening.
CAUTION: Do not press filler hook upward or oil deflector cap can be pushed off.
10. Reinstall ATF filler plug. Tightening torque is 24 Nm.

You would be better off replacing your regulator. You should be able to purchase one without the motor. It jumped off the track for some reason. Your cable is stretched now (more than likely) and this will cause you further problems down the road. After you replace the regulator, be sure to lubricate the window guides with SILICON WD-40, not regular WD-40. Use it liberally and cycle the window up and down numerous times then let it dry.

Not sure here as a modern motor vehicle is a complicated piece of machinery ,without reading the OBDII and having a drive my self its very difficult to give a answer as you no doubt appreciate,Now your problem could be anything from a fuel pump in the tank going down to a burnt or corroded connection on anything from a sensor to the fuel pump itself .Now as its a audi and these cars are nearly bullet proof it has to be something or nothing so i would suggest you ask a local mechanic to have a look and see what they can find ,failing which its the main dealer who can sometimes work out cheaper as you have a brand mechanic who knows his or her make of vehicle ,although ask any backstreet mechanic like myself and they will call them unit changers as thats mainly all the younger ones are .

P0420 means that the catalytic converter is operating below efficiency threshold. Normally, you only get this code if both O2 sensors ARE OPERATING PROPERLY. If you change the O2 sensors and still get the same code, it's an indication your catalytic converter needs to be replaced. But before you replace it, ensure that everything else in the engine is operating properly, so that whatever may have damaged your current catalytic converter doesn't damage a new one.
