can anyone help me with my lambda problem after replacing the front lambda twice i am still getting.

17511 - Oxygen (Lambda) Sensor Heating: B1 S1: Performance too Low
P1103 - 35-00 --
then lambda not active.

the only thing i can think of is crap maf..... or i have noticed that the lambda probe i have put in is a round tip not square with holes in. looks like a univeral lambda. anyone with any info. the eml is driving me mad.
 
i had this problem it was the maf ,after me nearly replacing all other sensors lol ,A faulty maf can be the cause of many a rouge fault codes
 
right this is for anyone else who has ever had this problem or ever will. in the end after replacing the lambda three times and endless searches. it was the MAF sensor. thanks to anyone who helped seatcupra.net is the best.
ps dont always belive what vagcom says
