Check engine light came on the 2006 audi a4, what should i do?

those are not OBDII codes. Call audi svc Rescan, if u come up with the same info, OR GOOGLE IT!

Most of the time when an epc light comes on and you have no throttle response it's best to connect it to a bag-com but if you don't have one have the computer scanned for a check engine code remember just because there's no check engine light on doesn't mean the ecu doesn't have on in memory.. So if you do have a code like p1639 then you have a bad accelerator peddle

The first thing that you must do here is to have the systems computer checked for fault codes, it should have a few in memory. the codes are read through the diagnostic port under the dash.

possibly the diverter valve. Pretty common problem. There was a TSB concerning those.

the battery light coming on usually indicates that the alternator is not charging you can check it yourself if you have a volt meter,it should charge between 13.8 & 14.3 volts ......hope this helps.....cheers

HAVE THE SECONDARY AIR INJECTION SYSTEM CHECKED OUT.TO MAKE SURE ITS ELECTRIC MOTOR PUMP ASSEMBLY VACUUM VALVE SOLENOID COMBINATION AIR SHUT OFF CHECK VALVE AND TUBING IS INJECTING FRESH AIR TO EXHAUST MANIFOLD.CHECK IT FUSE AND RELAY.GLOW PLUG LIGHT.COULD MEAN A FAULTY GLOW PLUG FUSE OR RELAY PROBLEMS.

Could be a broken motor mount, so that one of the pulleys is scraping a shroud or some other fixed item.
Examine the area around the pulleys and see if there is bare metal below one of them.
If so, have the motor mounts checked.

Hi,
the squeal is caused by a belt,not tensioned correctly ,I would check the cambelt tension first and then the serpentine belt,if not obvious you need to take to a Audi trained garage.If you plug in a code reader it will help point you in the right direction by the fault code.

well, as long as the engine lite is not flashing, it is considered safe to drive temporarily. i suspect you could have a misfire issue. need to read codes in vehicle computer. ill try to help best i can. are you mechanically inclined? may want to go to autozone for free code scan and get code # for me. could be spark plugs, coils. other variables involved as well

take it to an audi mechanic and reprogram the computer. it cost around $35 dollars.
