To my undertanding ('m not a mechanic) the communication beetween the MAF sensor are interupted or missing. As a warning the system then shut down the ABS and then PSM. Most probably in your case it is a bad MAF sensor (common problem). If not, i don't now ? Maybe leaks etc. as you can read above. If this happens only one time, i will not be worried. But my experience is that this kind of error messages show up time and again. On my car this is happening every time the boost hit 1 bar , 4-5000rpm, = full trottle. On "normal" driving there is not ABS/PSM light. On mine everything pointing in the direction corrupt ECU. But early next week i will know. Oh OK, its sort of like the only way the car can tell you the MAF is dodgy or hoses or DVs, i get it Thx for your post Have had a dodgy MAF with previous C4, interestingly came on during cold humid conditions too. I wasn't on boost at the time but cruising in 6th gear on Freeway at 100 kph Appreciate your input Hope yours gets sorted Plesase post how it all ends up, I might need to know All the best Andrew

Thanks for the post I picked up my 2002 996 Turbo yesterday I took to work on freeway today and what should come up, but ABS and PSM failure warnings And the next lights I restarted the car and codes went When I checked the on board check feature the warnings had been removed I hoped there would be something on Renntech about this, and viola a post today on same subject so thank you I DON'T QUITE UNDERSTAND : why is MAF related to an ABS/PSm failure Mine is a 996 TT with x50 package Only mod is after market exhaust Its run fine the rest of the day and no repeat warning Its just been serviced two days ago and everything checked perfect Should I be worried??? Interestingly it had rained in the morning and it was very cool and humid, a bit unuual for Perth recently with the drought Any ideas
