Need some help !! I'm repairing a 2005 audi a6 3.2 that was hit lightly in the front driver side near the power steering pump, engine shifted a bit had to replace the oil filter canister which crack when it hit the firewall replaced that engine mounts ,ps pump,air filter hose now try to start just turns over and over .. The epc light stays on while cranking , by the way the nav unit was stolen from the trunk not sure if that anything to do but i was told the car still should start . Any idea's open for suggestions thanks.

 

get a vag-com and read the code?

 

Fuel shutoff?

 

checked all the fuses traced all the wiring to each coils to see if damaged all looks good ,i hooked up the vag com with 2 readers both come off error in connection i'm thinking how can both have bad connection and the fuel is coming but no spark ?

 

Is there an air leak? My a6 had trouble starting when there was an air leak near the secondary air pump.

 

are far as i can see no leak at the secondary pump, and if there is a leak shouldnt it still start but run rough, and does the large air hose going from the trottle body to the air filter has to be there to start?

 

First off if the motor shifted due to an impact... it wasn't lightly hit.

lightly hit cracks a bumper cover..... or breaks headlight glass.

I'd be checking your battery and battery manager

 

i rebuild more serious hit cars i guess the block wasn't cranked thats why i considered it lightly , as far as the battery i was boosting it with another car the one in the audi is completly dead would that make a difference ?

 

I would think so.. Had have it done before where i had to replace the battery before I could jump it. The old batt would just pull the power way down.

 

i just replaced the battery and still no start, i have ordered vag-com can scanning usb with software see what codes comes up and clear them .it will take 2 weeks in the meain time i appreciate the feedback and see if i can get it going , anyone know if these cars have a theft shut down cause like i said earlier the nav unit was taken off the trunk or cause of the accident the computer shuts off spark to the coils cause fuel is coming thanks.
