Run the fault codes as it may be an accelerator position sensor.

Have you had the vehicle put on a diagnostic machine, does the car feel slugish, any lack of power, we have seen a lot of these vehicles with air mass sensor faults. When they fail they do not show a code but with the right scanner they can be seen not working. This affects the gearchange because the ecu does not have the correct data to shift. Of course it could also be the transmission is in need of overhaul. but i would take it to a good diagnostic garage first. It is not uncommon for the air mass sensor to fail after it has been disturbed or knocked in the workshop. we have never found out why.

I would have the cooling fan checked, and have the thermostat changed. An overheated thermostat (overheating caused by something else) will cause problems in the future.

First you must diagnose why windscreen wipers going slow and/or stopping.
In order to find out the cause of wipers stopping you can try follows: 1. Carefully extract the wiper arms from their axles (two pieces). In some cases you need to use an extracting tool. Heed of the windscreen !!! 2. Disassemble the plastic covers from the bottom of the windscreen. 3. With the bonnet up you can start the engine, (transmission in "N" or "P" position and parking brake on). Now you must switch on the control lever of the wipers, and go to the engine compartment. If the wiper motor runs let the wiper motor running for a few minutes and switch off. Go to the step 4. If the wiper motor do not runs you must check first the electrical feeding of the motor. It is necessary to unscrew three bolts of the mechanism and disconnect the electrical coupling (difficult assurance). If the electrical feeding is OK you must replace the motor - steps 5, 6, 7. If not you must check electrical connections, the control switch of wipers and electric cables. 4. Now you must check the two bearings of wiper mechanism with your hand. In the most cases the left bearing is out of order (is very hot). This is the most encounter fault of the wipers running at Audi. 5. For have enough space to manipulation the wiper motor together with their mechanism you must extract the plastic cover of the engine computer box, and extract also the box screws. Then you can move slowly the engine computer box, just for a few milimeters. 6. You must disconnect the electrical coupling of the motor (difficult assurance), unscrew three bolts of the mechanism and extract together with the motor. You must move them slowly between windscreen and engine computer box until the wiper motor go out together with the mechanism. This is the most difficult operation! 7. Now you can repair the bearings, replace entire wiper mechanism or replace the wiper motor. It is not very simply, but it works.
Heed of the windscreen !!!
Refit all in reverse order.

Hello
The engine
and automatic transmission in this vehicles drive train
are fully electronically controlled by a computer called the PCM
(Power Train Control Module). Whenever a problem like this occurs the
computer stores a record of the problem (there are of course some
exceptions to this, like the fuel pump, engine coolant temperature
sensor and MAF sensor for instance) in the form of a fault code in
its memory, to read these fault codes you must have the systems
memory scanned with a special tool. Once the fault code(s) are read
you then must perform the appropriate diagnostic testing to find and
resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A
TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
