Default I am blown away!!

So thanks to the help from here, my awesome Audi engine is performing as it should. I installed the MAF and took her out for some logging.(Or should I say flogging! LOL.
185.82 g/sec was the highest recorded number.
Unbelievable the zip. I needed this inspiration.

Now I just need to fix the rest.

Have a Haldex loaner from HPA and hopefully this will fix the CAN-comm problem. I did the driving test and didn't see any difference in the slow down. The car definitely hooked up in the rear. On one of the logs I got some wheel hop from the back and had to let off.

Does ESP/ASR stop wheel hop when it's working?

Anyway tomorrow = DEFCON 3 (thanks Steve - World Impex delivered as well), front end service, rear-end service, (suspension), Gearboxes, Haldex, etc...

If anyone knows of any wear area or item I should look at while I'm under this beauty, please let me know.

Al of the great help I have received has been greatly appreciated.

I ordered a performance controller from HPA. They got a bad shipment, so they are waiting for a new shipment. They sent me a stock loaner I will install tomorrow. I am hoping for no more yellow triangle on my dash!

I would have taken you up on that last week. Too late now.

Thanks for the offer.

What are you running in your car now?

Default oooo...the most common cause of the "Yellow Triangle" error code is a fault in the Anti-lock braking

system.
It doesnt appear to be fault that affects the ABS to function as it should, but instead is a malfunctioning sensor. Audi put out a repair kit for this problem about 3 years ago. You no longer have to replace the unit.

The codes I am getting are no communication with the AWD controller.

The ABS measuring block 225 reads the ECU and Steering Angle Sensor on the CAN Bus, but no AWD Controller. No ABS light, just ASR.

Yes, sorry ESP. I can switch on and off sitting still, but comes on after moving.

I will swap the controller and at least know if that ws the problem.

Default sorry. i check this forum sparingly.

I am pretty sure that the problem that you describe is the ABS sensor issue.
The light in your dash would not come on, until you have exceeded 12-14mph...

Lemme know if the controller swap works for you.
