Re: 2002 Jetta TDI Error Code P0128
Welcome to the forum!
Have you tried searching the appropriate VW Jetta forum? This appears to be a pretty common issue with the 2001 and 2002 Jetta, and appears to point to a bad CTS or connection to the CTS. It appears most people have issues with aftermarket CTS, but OEM work fine. It also appears that VW issues a TSB addressing this common issue. The VW Jetta forum will probably have more details for you. -Rod |

According to this site its Long Term Fuel Trim B1 System Too Lean. Not busting chops, but that took a google search and one click

But, agreed, I did a quick Google to find a multitude of information on the P0128 code, and I suspect much of the same information could also be found in the VW Jetta forum on this site. -Rod |
