Hello, had a problem with my 2008 pd170 BMN audi a3.
It started 10 days ago when my engine randomly died at low revs while parking, it would not start again until after several minutes and then ran fine again. Now I got a code for the G28 speed sensor (00801) and voltage low of ref circuit a (001602). I've read that any faulty sensor on this circuit can trigger a a low voltage code such as this, so a possibility that if the g28 sensor is faulty itd also cause that code?
Anyway, since then it was absolutely fine until yesterday when it stalled/cut out while driving at around 30mph, it felt like someone killed the ignition for a second or two then put it back on (the revs fluctuated by about 400-500rpm while this was happening despite me being in gear and still rolling so impossible for them to actually fluctuate by this amount.
Since then its happened a few more times, but only lasts a second or so then the engine is completely fine again in all ways (no loss of power etc) and when it does cut off and i'm not in gear it restarts instantly again.
Now as i said i've only got the two previously mentioned codes for the 14th of this month and none for this weekend, could this be a warning of a faulty speed sensor and it didn't fail long enough for it to trigger a code? or something else? it seems easy enough to change so i was going to go to TPS tomorrow buy a new genuine one and change it myself unless anyone has anymore information and can point me in a better direction?
Thankyou for sticking with me this long!
