Hi I've got a octavia 1.9 tdi estate and had falts come up on the dash put them on a diagnostic and come up with sensor for level control (g84) and abs inlet valve front left (n101) and abs wheel speed sensor rear left (g46) I've put a new sensor on this side but still coming up with the code also abs wheel speed sensor rear right (g44) and the last one refrigerant pressure sporadic 002 lower limit exceeded if anyone has any advice or comments I would be grateful thankyou

Have you had any suspension work done lately?.......there is a level sensor connected to the the front near side wish bone and I think another one on the rear. Worth checking they are both physically connected to the suspension.

I'm not sure about the ABS faults, but it might be worth giving the whole setup a good clean.

Refrigerant sporadic lower limit exceeded sounds like the aircon simply needs recharged....aircon gradually looses pressure over time, and soon the system won't work at all as the low limit will be exceeded all the time.

Do you have the actual fault codes?

they sensors are for the xenon head lights if fitted. they have no other function for the car.

I got the " refrigerant pressure sporadic 002 lower limit exceeded " which turned out to be the pressure switch

Yes, but if they are left disconnected or are removed and reconnected without the calibration procedure carried out in VCDS, they will produce a fault code.......as I found out recently after getting the front wishbones replaced.

Sorry about taking so long to reply the codes are 01393 sensor for level control. 00257 abs inlet valve front left. 00290 abs wheel speed sensor rear left sporadic. 00287 abs wheel speed sensor rear right sporadic and 00229 refrigerant pressure sporadic 002 lower limit exceeded thankyou for any replys
