Problem with ACC on Audi A8 2004 3.0 TDI

I have had my ECU changed and after i got it back i am having problem activating ACC - I am getting the message "ACC not available". Can it be that the function is not activateed after changing of ECU ? I have checked with diagnosting tool and it shows that one of the enginge mounts ar faulty - can ACC problem be associated with this - did not have the problem with ACC before ECU was changed.

Who changed the ECU, you, or shop, was the ECU programed for your car or was plugged in and start.
most likely it need to be programed and apdated.

SOURCE: how do i change my fan belt on an audi a4 19 tdi

i just replaced 1 yesterday your best option is to remove the headlights, bumper, you will see 3 torx bolts both sides holding complete front section, remove air conditioning rad pull round to right hand side without losing pipes, the front section should pull round to the left a little prope with axle stand. draw out a digram of witch way the belt goes round all pulleys. to the left of the water pump (big fan wheel) is the tensioner, to slacken place 15mm spanner on bolt and pull anticlockwise.

The TDI.s are known for carbon build up in the egr cooler and intake manifold. Ive seen them so built up that you couldnt fit a pencil into the intake! Its a few hours of labor to get all the carbon out of there but the van will run like it used to! Book time is like 3 hrs to do it but well worth it. after its done youll agree! Ive been a ve audi tech for 10+ yrs. Ive done this procedure many times. Its easy to pull the throttle body off an have a look in the intake to see how bad it is. only takes 25 min or so.

It does not have power to overtake although when stood it will rev it is an audi A3 1.9 tdi and is 2000


Your motor probably runs in "failsafe" mode (won't go past 3000rpm in highest gear), but in that case the ECU warning light should also come on (which might also be broken ofcourse).

Try releasing and reconnecting the battery (-connectors), which should "reset" any fault-codes in the ECU and see if the TDI power is back. Please note that the "cause" of the ECU faultcodes will probably put the motor back in "failsafe" mode within minutes ! But at least you've verified that your motor runs in "failsafe" mode due to serious faultcodes in the ECU.

You should have a dealer/expert read the ECU faultcodes using VAGCOM to determine the cause. A dealer will charge something like 50~60$ for it.

Since it's a 1.9TDI my best guess is that's it a broken N75 turbo-valve (common TDI issue, replacing the part yourself will cost less than $30 and 15 minutes). When the dealer suggests a complete replacement of the Turbo-unit (quite expensive), please have a TDI-expert do an 2nd opinion ...

I don't think this is possible. Your AFB engine requires an AFB-compatible ECU. The AFB code is specific to that engine design due to parameters of the engine itself. My 99 A4 has the AHA V6 30v engine, which can only be controlled by an AHA ECU. Changing the ECU does not change the engine itself, and trying to use an ECU from a different engine code will not work. If you want to use a different engine, you'd need that new engine's ECU, engine bay harness, accessories and mounts, and possibly even the chassis harness from the donor car. It'd be a tremendous amount of work.
