Hi All,

I'm currently trying to address all of the error codes my E46 is pulling up.

Yesterday, I took it to halfords to get the air-con refilled and found out that they will read the codes for £30... same price as my indie so i went for it. Anyway, the codes that i was most concerned with involved the lambda/o2 sensors and fuel supply.

When the guys tested the individual components relating to the error codes (for about 30mins) he could not get any errors or spot any problems with the readings...so he reset the lights and didn't charge me. That would usually be great but im still having issues, bare in mind that i had resets the lights a week before so the errors are current.

What does that mean? ECU problem?
The symptoms are that i get no power when i put my foot to the floor especially when i start the car in the morning or after it has been standing for a while.

The light hasn't come back on yet... but i haven't driven much since yesterday. As soon as it does i'll take it back and get further diagnostics. For now, Any ideas guys and gals?

Much appreciated

Jason
