My Saab 1.9 TID 9-3, built in 2005…117000 Tkm, 2 years ago to have new AGR valve installed, 4 months ago to have new AGR valve installed, yesterday on the Metz-Berlin route…the power drops… then leaves more after …the engine control lights up ….. I already know, drive to the next parking lot, call the ADAC…he is very fast there…I say what’s going on….he reads the error….but can only determine the error number and not describe text daz u (his software only lasts up to the 2.2 diesel engine)…..then he takes his hammer…happens a little bit on the valve…deletes the error and we make a small test drive…..Check engine is off, engine runs and pulls as it should….I drove through the remaining 300 km well. But what now? Is the fucking valve already ready for change? Isn’t there a better solution than to call the ADAC because of a few hammer strokes? Can one possibly call such an AGR valve than Put the spare part in the car and when Check Engine lights up is changed quickly and continues. At home you can let the thing pass through the washing machine (of course wrapped in a bag) you have a clean spare valve again. Or does the self-installation of the carried AGR valve do nothing because you can not access the software to delete the error memory ? MfG Isenhagen
