might aswell change it then. i have located which is the first task for someone like myself. Anyway an update i cleaned the MAF warmed her up and took her out for a blast. The car was fantastic no overboost protection and it seemed to boost better. The MAF was certainly dirty. Should it get that dirty in 4 months? I have recently changed the air filter as the old one was a bit of a state could this have an affect? I also reset the ecu by pulling the fuse, would this hide a more serious problem if it turns out not to be the MAF. Thanks for your help

SJM Autotechnik: Output Tests

1992-96 S4/S6 with AAN 5 cylinder 20V Turbo Engine

There is also an "output test" mode that will cycle the engine electrical solenoids on and off to verify they are working correctly. You are able to test the 5 Fuel Injectors Idle Stabilizer Valve (ISV) Carbon Canister Solenoid Valve Waste Gate Solenoid (waste gate frequency valve)

To activate the Output Tests, you must first connect the Jumper Wire across the Fault Code Connectors as shown in the above diagram and THEN turn on the ignition to initiate the output tests. (DON'T START THE ENGINE) After the ignition is turned on, remove the jumper wire after at least 4 seconds.

FUEL INJECTOR TESTS: After you have removed the jumper wire, you can place your fingers down on fuel injector #1 and then open and close the throttle with your other hand. You should hear and feel #1 Injector click 5 times and then be quiet, place your fingers on Injector #2 and again open and close the throttle, Injector #2 should click 5 times, place your fingers on Injector #4 and open and close the throttle, Injector #4 should click 5 times, repeat for Injectors #5, then Injector #3
After doing the last injector test on #3 the Output test will switch to testing the IDLE STABILIZER VALVE (ISV). You should hear this Idle Stabilizer Valve clunk open and closed..
Connect the jumper wire again for 4 seconds to go to the next output test:
The blue Carbon Canister valve behind the idle stabilizer valve (behind throttle area) will be cycled on and off. You may want to place your hand around the carbon canister valve to feel it operate.
Connect the jumper wire again for 4 seconds
The Waste Gate Solenoid on the intake boot near the turbo inlet will be cycled on and off. This valve operation is pretty loud, so you should be able to hear it operate.
Connect the jumper wire again for 4 seconds.
;End of Output Test Procedure, fault code memory has been cleared.
NOTE: To repeat the Output tests, the ignition should be turned off for at least 20 seconds. If Output tests are repeated, the INJECTORS will NOT be cycled again, unless the engine is started and run briefly.

The 2x2 connectors is in the fusebox, under the bonnet, you jump the front 2 pins on each of the white and black connector.
