Repair And Fix it

Disconnect the negative battery cable with a socket wrench. Detach the accessory drive belt from its pulleys. Turn the crankshaft clockwise by hand to align the timing mark on the crankshaft pulley with the timing mark on the crankcase. The timing marks on the camshaft must also align with their respective timing marks on the crankcase.

Remove the plug from the left side of the engine block by the crankshaft with a socket wrench. Align the timing marks on the crankshaft again if necessary. Connect Tool No. 3242 to the crankshaft and tighten it slightly to hold it in place.

Disconnect the upper timing belt covers, crankshaft vibration damper and lower timing belt cover in that order. Loosen the mounting bolts for the camshaft sprockets with a socket wrench, and release the sprockets from the ends of the camshafts.

Turn the roller for the timing belt tensioner clockwise with an 8 mm Allen wrench to compress the tensioner. Place a 2 mm spring pin through the holes in the tensioner housing and plunger to hold the plunger in place. Turn the tensioner counterclockwise to release the tensioner.

Remove the mounting bolts for the crankshaft damper with a socket wrench and detach the damper from the crankshaft. Disconnect the serpentine belt from the idler pulley and remove the guard for the crankshaft damper. Detach the timing belt from its pulleys.

Align the timing marks for the camshaft and crankshaft pulleys, if necessary. Place the new timing belt onto the pulleys, so that the arrow on the timing belt points in the clockwise direction.

Turn the roller for the timing belt tensioner clockwise with an 8 mm Allen wrench to compress the tensioner. Pull the 2 mm spring pin from the housing of the tensioner plunger. Turn the tensioner roller counterclockwise to apply tension to the timing belt.

Connect the damper guard for the crankshaft and attach the serpentine belt to the idler pulley. Tighten the mounting bolts for the idler pulley bolts to 33 foot-pounds with a torque wrench. Replace the crankshaft damper and tighten its mounting bolts to 15 foot-pounds. Fasten the mounting bolts for the camshaft sprockets with a socket wrench. Install the timing belt covers.

Remove Tool No. 3242 from the crankshaft pulley. Install the sealing plug into its hole on the lower left side of the engine with a socket wrench. Attach the accessory drive belt and connect the cable for the negative battery terminal.

Turn the key in the ignition to get your A6s instrument panel to engage. Look over the dials on the gauges and make sure that you have enough fuel to start the vehicle. If you dont have enough gas, fill the tank up and try to start the car again. If the instrument panel does not light up, you have a problem with your battery.

Open the hood with the hood release latch on the driver side under the steering wheel. Raise the hood and lock it in place with the hood rod. Check over the connections to the battery on the left side of the car.

Tighten the connections with a pair of pliers. Make sure that you dont have any corrosion on the battery cables. Clean the cables with soda and a wire brush to remove any corrosion.

Test the battery with a voltmeter to check its charge. If you have less than 11 volts running on your 12-volt battery, attach a battery charger to the battery terminals.

Leave the battery charger on the battery for at least 12 hours to charge the unit. Try to restart your car. If the car does not restart, replace the battery with a new one.

Locate the cooling system on the left side of the car if your A6 is overheating. This is labeled as "Coolant." Make sure that you have enough coolant in the system. Fill the coolant tank with 50/50 mix of coolant and water until it reaches the fill line on the side of the tank.
