Hi, 2017 T6 with cxgb engine. I'm trying to bleed fuel system but vcds says "Service not supported in active session". Same thing with other basic setting options also. I could not even enter secure code.
hex v2 cable and newest version.

Please post an Auto-Scan (full and unedited using the English version of VCDS) so we can see how your T6 is equipped and configured.

A newer interface will give you more complete diagnostics, but your HEX-CAN shows some significant problems on 01, 09, 13 and 18.

I'm trying to bleed fuel system but vcds says "Service not supported in active session".
What exactly are you trying to do to make this happen?

Have you tried clearing fault codes in the Engine first?

i have hex+can cable. This might be too old for this ecu.
Nah, it should work for this.

It is possible that the errors in 01 need to be cleared/solved first?

For me this code works after i copied that file. Bleeding works but car didnt.
Car wouldnt start after short brake. Timing belt has popped 2 tooth and i have changed belt, waterpump, high pressure pump, filter, diesel tanks was drained and filled with new diesel and meny sensors. Inmjectors has tested and all works fine. Camshaft and rockers are good and no error codes at all. Engine cranks, rail pipe pressure is about 350bar but doesnt run. cxgb engine, 150 000km driven.

Have you checked the compression on all cylinders after replacing the timing belt?

Try firing it on propane or a tiny touch of carb cleaner, if it fires then your cam/crank timing should be good, if it doesn't start back at timing.

Engine runs nice with brake cleaner. I quess ecu doesnt give permission to run and injectors wont open. Couldnt understand why.
Rail presure sensor and both camshaft and crankshaft sensors changed and tested also with originals.

Not being familiar with that engine code have you double, triple checked the high pressure fuel pump timing for accuracy on the timing belt?

Timing is done with locking tools and couldnt be done wrong. Of course, checked 3 times.
