what causes an A2 232 code?

Post by Clemens »

So my 94 T5m wagon had a sitting dog when I bought it and the blinky box revealed a 232 on A2, long term fuel trim. I was able to delete it. But what caused it? After 7 years of 850ies this was my first sitting dog. Very exciting...

Most of the time it is a vacuum leak. The elbow at the end of the intake manifold is the usual suspect, since it is the hardest thing to get to without pulling the manifold it is, of course, where the problem usually is.

Thanks, i need to do the pcv anyhow. A cheap new car is always full of opportunities to get the wrenches out.
