Hesitation, power loss no error code
Hi All
My n63 motor is experiencing slight hesitation on acceleration and have noticed a huge loss of power . Idle is fine. I've scanned the car with obd and the torque app and see no error codes . Any thoughts would be great?? |

Could be a boost leak. Do you have something that you can use to measure boost?

I've had similar symptoms for awhile now... Brought it in to have it looked at 3 separate times at 2 different shops.
Originally was a vacuum leak with no fault codes... Fixed that. Then symptoms seemed to come back after a week or two. Brought it back into the Indy shop and they scratched their heads saying nothing was wrong. Wasn't satisfied with that answer so I brought it to the dealer to hopefully get a different opinion or answer.... Nothing from them either. About a week after car goes into limp (low power mode) and throws a code for water pump short circuit. After cycling the car in/off its back to "normal" power...Call the dealer and all they say is water pump is toast and to bring it in to have it replaced for $1500 (lol) (with no actual diag other than my own). So here I am in your boat... So I'd recommend vacuum and pressure testing it to start then go from there... Edit: vacuum leak would probably give a poor idle though. |
