I was wondering if anyone had any ideas why my sensor code 133 won't go away? I have an 03 V40 and have fixed both oxygen sensors twice the last time was some replacement kit sold to me by my mechanic who was told by the the dealership that this would solve the problem. It's still there.. my mechanic has turned me away at this point and referred me to a dealership after spending around 800.00 on this I'm at my end... and I need to pass emissions next month...
What about "flashing" I was told by another Volvo mechanic that I would need to do this, but other "experts" say I may not be able to get the software back on my computer..
So sad that the new Volvos aren't the same... my 94 740 keeps on going....
