This is electronic (controll) problem on the engine. Have to control your car on the diagnostic.

screw on the outside of the door /door jam ,rubber boot over it ,take it out then pull door handle outwards and backwards at the same time and it comes out

what do you mean by launch >>???

Though I am not entirely familiar with the audi vehicle, mostly when trying to remove the outside door handle, you need to first remoce, the inside panel where the handel is located. Once this has been done, look to where the door handle comes to the inside of the door from the outside of the car. It should have some sort of a clip/ pin/ screw or other fastening mechanism, which holds it to the car from the inside. Remove that fastening mechanism and the handle should come off.

Check the codes!

I would check the OBD codes for clues.

Try the row of large switches above the radio. It is most likely the middle one.

Let's break down the situation: EPC Light: The EPC light typically comes on when there's a problem with engine sensors or components. It might be related to the throttle sensor or the temperature sensor. When the EPC light activates, the engine electronics may limit power and maximum RPM. As a result, the computer might restrict the engine's performance, allowing you to drive at low speeds only. Check Engine Light: The Check Engine light illuminates when the engine management system detects a fault or error. The codes you've provided indicate specific issues: Code 17950/P1542/005442: Angle sensor 1 for Throttle Actuator (G187) has an implausible signal. Code 16891/P0507/001287: Idle Control System RPM is higher than expected. Possible Causes and Solutions: Fuel System Issues: Given the fault codes related to fuel pressure, it's essential to check the fuel system. Low fuel pressure could cause hesitation and trigger both lights. Mass Airflow Sensor (MAF): A faulty MAF sensor can lead to engine hesitation, rough idling, and stalling. Consider inspecting or replacing the MAF sensor. Throttle Body: Although the dealer replaced the throttle body earlier, it's worth verifying its functionality again. Idle Control System: The high RPM issue might be related to the idle control system. Inspect the idle control valve and related components. Wiring and Connections: Check for loose or damaged wiring, connectors, and vacuum lines. Next Steps: Diagnostic Scan: Perform a thorough diagnostic scan to identify any additional fault codes. Visual Inspection: Inspect the throttle body, angle sensor, and wiring connections. Fuel Pressure Test: Verify fuel pressure using a fuel pressure gauge. MAF Sensor: Consider cleaning or replacing the MAF sensor. Idle Control Valve: Inspect the idle control valve for proper operation. Remember that intermittent issues can be challenging to diagnose. If the problem persists, consult a qualified mechanic or an Audi specialist to pinpoint the exact cause and address it effectively.

Read the ODB2 codes for an accurate assesment.

The fuel pump fuse is located in the engine bay fuse box. It is the 2nd row from the top, last fuse on the left.

The OBD2 port is connected directly to the ECM and data from other modules is shared from there. 'Mechanics' deal with the mechanical aspects of the car, you need a specialist auto electrician. They have the knowledge and experience and the ability to access and read wiring diagrams. https://www.google.com/search?q=auto+electrician+near+me The first thing to check would be the connectors on the ECM and BCM. Then open them up and look for burned out components. Full wiring diagrams normally require a website paid or unpaid subscription. https://www.google.com/search?q=1999+Audi+A6+Avant%2C+1.9TDI+wiring+diagram Re-reading the question, did you have one model and year of vehicle and then replace the engine from a different year and model? You can't do that, the ECM has no idea what's going on. ECM are dedicated to the engine it is connected to and programmed accordingly ..

car sold to what country ? what is VIN,m what exact engine options is there books are by full car name spec, engine, VIN, and country sorry we can't guess all that. ask Audi this new care mostly do not have the service manual sold yet. but ask them nobody else has it for sure not published yet. same answer for 100 years.

where does it leak from, investigate, you may need to tank, could be hoses. Unable to investigate take to repair shop.

The trouble code B10AE31 in an Audi Q7 pertains to the air conditioning system. This specific code indicates a fault in the air conditioning control module. To diagnose and resolve this issue, you may want to try the following steps:

1. Reset the system: Sometimes, a temporary glitch can cause the code to appear. Try resetting the system by disconnecting the car battery for a few minutes and reconnecting it. Then, check if the AC starts working again.
2. Check the fuses: Look for any blown fuses related to the AC system. The AC system may not work if there is a blown fuse. Replace any blown fuses and see if that resolves the issue.
3. Scan the vehicle: Use an OBD-II scanner or take your vehicle to a qualified mechanic to scan for any additional trouble codes. This will help identify any other potential issues that may be causing the AC problem.
4. Inspect wiring and connections: Check the wiring and connections related to the AC system. Look for any loose or damaged wires or connectors. Repair or replace any faulty components as necessary.
5. Consult a professional: If the above steps do not resolve the issue, it is recommended to consult a professional mechanic or take your vehicle to an Audi dealership for further diagnosis and repair. They will have the necessary tools and expertise to accurately diagnose and fix the problem.

Remember, working on the AC system of a vehicle can be complex and requires expertise. It is always recommended to consult a professional if you are unsure or unable to fix the issue yourself.

gee a 20cent blown fuse is cheaper.' check all fuses then scan the PCM for tranny errors. using a scan tool.' there are near 10 on car checks on any failing A/t seems you skipped all that. USA car or not? we oops no 2.4l here USA> so you are posted outside USA and didnt say so first. ours has 7 solenoids in the box. tranny, and if the TCM is not happy how and can it shift right.? and EPC inside to set pressures right. ours uses A6 Quattro; Trans. Code 6HP19A; I say check all fuses., then scan the pcm/tcm then ask for help with P07nn or P17nn errors called DTC's the box is 100% electronic shifted, how can you forget to check status of the TCM./

parts costs for any car , on earth are not the same all over earth not even close, . unless in N,Korea or Cuba. new, used , rebuilt beside the mount error all those error could be just 1. even vacuum leak. P0300 says all cylinders misfire so there other P030x error are pure redundant. cam sensor is serious, in the real world that cam sensor error is very serious. and causes misfire, so misfire is expected why add up cost when you've no clue what is bad. OBD2 DTC are just the starting point of diagnosis the PCM is not AI, not by a country mile ,even to the moon. we cant watch you or the car ( in the secret act) did you crank a dead engine so LONG, that battery went low and now all computers in the car are telling lies, and is common as nails now. this effect.. no symptoms told at all just a DTC dump. no engine told at all and A4 4.2 L V8 40v DOHC >< complex this. seems it is just 1, posted ANON so no other way to know what engine is here. nor there post full of symtoms not told here and what happened the day this all started. engine died? what? starter cranking slow is not good, step 1 on all cars , we keep the battery fully charged till the engine starts to run and stays running and battery volts are 13 to 15vdc, a volt meter tool find that easy. if below 13vdc the alternator is dead or its fuses.blown. also we do not sell engine parts. here. just free advice ,just that. no miles on the car told, over 90,000 miles and the silly cam belt failed. making CAM sensor go dead? the belted cams can not be ignored the belts are changed out at 90k miles 140km https://www.rockauto.com/en/catalog/audi,2005,s4,4.2l+v8,1430752,engine,timing+belt+&+component+kit,5759 good luck , DTC codes are not AI, not at all

Door is open, latch is closed. Use a screwdriver and place it in the latch. Using the door handle, release the latch while pulling the latch open. Now, close the door.

automatic transmission or manual stick, the brake/clutch switch operations are NOT THE SAME on both car options. no country told, lighting (for sure external) are not the same all over earth, sorry I do not make laws (like DOT USA?) or anywhere. this forum is www, a world wide web forum. so where are you ,a country.? and you work with no voltmeter or service manual schematic. and no scan tool? wow endless guessing done. throwing parts wild. its is modern car, 2009 totally unlike a 1990 or 1980 or older car. for sure. there is never a need to replace all fuses ever, testing is super easy even if they all look good. (did they?). (look test, ohms or volts tests) that melting thing means a lamp shorted. (they can) I see reverse lamps failing and parking lamps the transmission PRNDL SWITCH MUST WORK IN "R" OR THE LAMPS WILL BE DEAD REVERSE. BOTH WERE SO..... I GUESS INDICATOR MEANS turns signals failed( blinkers) the car has 4 corners, why not tell what all 4 do when Turns or parks fail.?>??? what they all do outside matters most. (electrics) the huge problem here is not scanning the OBD2 port with a real scan tool. I bet it tells you why it fails I sure do but you failed to do that. does this car have the parking AID option? does this car have optioin Daytime Running Lamps, a.k.a DRL?>? also wiring for TT is unique so states the SM (service manual) i can't see you work on any car so now comes right parts questioln using only these parts., Rear Turn Signal Bulb

the German manual calls park lamps TAIL even when front and side park lamps are park lamps. same source. It does call TURNS turns, so we can find the correct schematics, searching the online service manual for you. most modern cars, use BCM to run all that. I call it the body brain each maker uses there names and Germans use CODES LIke J123. to name a model. (that must be decoded first to work the problem, yes a pain on all germane cars) deep in the manual i found the secret german body brain J519 - Vehicle Electrical System Control Module this module runs the whole rear (it has DRIVERS) Drives means electronic high power regulator drivers to lamps. that if it sees a short , it simply goes OFFLINE until cures. then magically goes back on one, J519 - Vehicle Electrical System Control Module M6 - Left Rear Turn Signal Bulb M8 - Right Rear Turn Signal Bulb M9 - Left Brake Lamp Bulb M10 - Right Brake Lamp Bulb M16 - Left Back-Up Lamp Bulb M17 - Right Back-Up Lamp Bulb M37 - Left Rear Side Marker Lamp Bulb M38 - Right Rear Side Marker Lamp Bulb T2g - 2-Pin Connector, In the Luggage Compartment, Right, Black T6k - 6-Pin Connector T6l - 6-Pin Connector, Black T12c - 12-Pin Connector, Black T12d - 12-Pin Connector, Brown X3 - Rear Fog Lamp 395 - Ground Connection 30 (in Main Wiring Harness) 662 - Ground Connection in Left Rear Side Panel 676 - Ground Connection 2 in Luggage Compartment, Left ------------------------ J519 is here Behind driver's left stowage compartment, beside steering column -2 Fuse 7 (On Fuse Panel C)? blown fuse? this car uses CAN BUS. many of the switches wire directly to the J519 Body brain but not all. lets look at that now, (my book is USA only SM) the steering switchs for park, turn and heads. are all sent to the cluster brain directly, then the cluster brain via the CAN_BUS network sends data commands to the J519 (body brain) then if this fails the scan tool told you it did but you never scanned the OBD2 port. while failing others found water leaks to dash module (windshield cracks or glued in wrong and leaks) some Audi versions 2009 have top of brake pedal brake switch that must work, and is direct drive signal to J519 TURNS are not switch actual direct drive to the J519. no. example 1 U1113 Audi Code lacking scan tools you will never fix this by guessing. sorry CAN Bus wiring intermittently open, shorted to power or ground U0001 U0155<< lost comms to IP cluster. and more lots and lots more possible we check all fuses in all fuses boxs A ,B,C etc. then scan the OBD2 port. for errors. for sure comm errors' see this fuse box? Main Fuse Box in Right Rear of Luggage Compartment on Battery see? drivers (electronic) to each lamp. proof (no fuses to lamps) so if one lamp shorts. the other do not die. by design and J519 must get the commands to turn them on first.
