2nd servicing time i;e how km and how much days

A C4200 IS A BAD LASER UNIT , EXPENSIVE REPAIR FOR A COPIER THAT OLD.

probably just your transmission being old and wear and tear catching up to it. engine braking is a good thing in a manual but since automatics cant judge how far to let out a clutch mechanism that doesnt exist to make it smooth, it usually causes more wear and tear than its worth. maybe time for a transmission rebuild and time to leave engine braking to manual transmissions. $30 brake pads vs $2000 transmission. hope this helps ya

It's the normal car service reminder due. Whichever will be reached first: 700 km, or 30 days. In other words after 700 km, or if you don't drive the car 700 km within 30 days, you should carry out the car maintenace: engine oil & oil filter, air filter, fuel filter, pollen & dust cabin filter, ...
Then you will need to reset the "Service due" message on the dashboard. For Audi Q7 made year 2010, the Service Interval Indicator can only be reset with the VAS 5051 or similar diagnostic tool connected to the data link connector of the car.

change the plugs and the air filter &try not to speed, that always consomes more fuel. if that dont help, change the plug wires

TO RESET, MOST VEHICLES TURN ON THE IGNITION SWITCH, [DO NOT START THE ENGINE ] PRESS THE GAS PEDAL TO THE FLOOR 3 TIMES, THE LIGHT SHOULD GO OUT. IF THAT DOESN'T WORK, YOU CAN DISCONNECT THE NEG. BATTERY CABLE FOR A MINUTE THEN RECONNECT, START THE ENGINE, THE LIGHT SHOULD BE OUT

For Audi A4 model 2003 1.9 TDI 131 HP the board computer message ,,Service in 2400 km 29 tagen" means: Service due in 2400 km, or in 29 days - which one: 2400 km or 29 days will be first covered. It's very simple!

Hi,
When the vehicle is started and right after the ignition check, if there are less than 300 km (200 mi) left
to the next Service, the specific icon flashes for 5 seconds. Once the service mileage has been reached,
the icon remains steadily until the Service is reset.
The warning light can be zero set even if the mileage is lower, up to 300 km (200 mi), compared with
the Service mileage. During the 300 km (200 mi) before the service warning light comes on, the light
flashes 5 times each time the key is set to ''ON''.
The light should turn on first at 1000 km (625 mi). Successive times are strictly at 10000 km (6215 mi)
20000 km (12430 mi), etc
RESET
Hold the MODE button down.
Turn the key to ''ON'' and wait 10 seconds.
During this operation the service icon flashes.
Good luck,
Alex
