Hi there

I wonder if you can assist me please?

I am running a throttle body alignment, and am getting some results that are confusing.

  • Before running the exercise, the 1st 2 values are 15.6% / 84.8%
  • I then change basic settings to on, and the procedure starts.
  • The throttle body opens and closes and after a few seconds the values settle at 12.5% / 87.5% and stay that way for 10-15 seconds, but revert back to 15.6% / 84.8%.
  • I then change basic settings to off.
  • No error was thrown during the procedure.

Is this normal?

You have no codes for the throttle body... your values are plausible, 15.6% + 84.8% = 100.4. The values of the two sensors in a throttle body should add up to appropriately 100 at any given position the throttle body is in.

The engine ECMs have codes for rich issues. Does the it have the correct spark plugs? Good compression? Leaking injectors? To help check for leaking injectors, have the engine up to operating temp (+80C coolant temp), then with the engine at idle, go to 01-08-106.1 and note the fuel rail pressure at idle. Exit out of the ECM, shut engine off, turn ignition back on but don't start engine. Go back into 01-08-106.1 and note the fuel rail pressure.

As a general rule of thumb, with a hot engine rail pressure should go up about 20BAR in 2 minutes with the engine off. Rail pressure gets trapped when the engine is shut off, and with a hot engine you get heat soak, so the fuel rail become a bit of a pressure cooker.

Thanks Jef

I know there are no codes specific to throttle body - I was wanting to make sure the values changing at the end of the adaptation did not indicate a problem.

I am planning to do a compression test (while we are at it I will re-check the plugs) and will also run the fuel rail pressure test over the next few days and report back.

There can indeed be no DTC's present in OBD2 or VAG mode with a TV error present & for a failed ADP in a TV controller.

In order to check a status of a TV, a review of blocks in VCDS is advised for the TV and TV kick down should be observed directly too.

Compression checks should always be done with a TV set to open/removed and flaps for intake set to full open.

So as per your suggestion, I took the fuel pressure readings - 1st with the engine running showed +/- 35 bar, the 2nd with the engine not running, about 30-40 seconds later, showed +/-7.5 bar and dropping.

I had all the injectors checked about 18 months (30,000km) ago and replaced a few that were dodgy.

I guess its time to whip them all out again and have them checked.
