So today has been a day of strange happenings.
As you may have read, my headlight bulb had repeatedly blown so I decided to have one last punt with VAG-COM and see if I could find the cause. To my utter surprise it worked and duly pumped out a whole heap of codes, too many to comprehend and most relating to that coil-pack problem I had a while ago.
However one stood out:
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 002 - Lower Limit Exceeded - Intermittent
So a had a quick browse round the net and read about disconnecting the MAF to see if it improves performance. So I did, I ran the engine and it didn't sound great, definately no improvement, then the ESP (yes ESP weird!) light came on the dash so I panicked and switched off, reconnected the MAF and cursed myself for being so adventurous. I restarted the ignition and to my relief the ESP light went out, still wasn't running too good though.
Next I VAG-COMed in and deleted all the fault codes and left the car for about an hour.
So later on I had to go to the shops, as soon as I started the car I noticed a difference, the idle was smoother, the enginer quieter and then when I started driving, the biggest grin came accross my face!
It was like I was driving a new car! Acceleration was smooth, the turbo was acting like a turbo should, engine noise dramatically reduced.
I have no idea how this happened, perhaps disconnecting and reconnecting the MAF forced the ECU to recalibrate... who knows... but I am a happy man.
So after my little trip I ran the fault codes one more time, so this is only after about 3 miles. This time just a couple, so I'd appriciate any hints:
Cheers.
