ok, if you have access to vcds could you log block 032 for your fuel trim. You don't need to start the car to log this block.
Also did you do a basic setting for the Intake Manifold Runner?
Im away in the van working this week but i'll log that when i get home at the weekend. Is it just a single number then? not something you need to log while out on a run?
Also im not sure about the manifold runner setting. I'll ask the garage that did the work but I can also do this when I get home with vagcom.
thanks for the advice.
There are two values for the fuel trim and doesn't require you to go for a run.
The first field tells the fuel trim at idle and the second field tells the fuel trim at elevated engine speeds.
Negative values indicate that the engine is running too rich and oxygen sensor control is therefore making it more lean by reducing the amount of time that the injectors are open.
Positive values indicate that the engine is running too lean and oxygen sensor control is therefore making it richer by increasing the amount of time that the injectors are open.
Specifications for normal operation are usually somewhere near +/- 10%.
