Have had a few issues on this car now down to the last for now, getting and error on VCDS 17591 Linear O2 Sensor; Reference Voltage Short to Plus, was intermittent but now the error without. Swapped for new NGK o2 sensor and 20 miles later light is back on and same error but with intermittent again now. What do you think - iffy connector or wiring from connector back to ECU or something else? Getting bored now! 2006 1.4 BKY SE
Hi, I own a 1.2 9n3 Polo (55 plate) I bought it in July 2015 and in October 2015, the check engine light came on. After taking it into a local garage and having it looked at by the mechanic, I was told I would need a new Catalytic Converter. I was also told that for the warranty, I would need both sensors replaced as well. So after nearly £400, it should now all be fixed. The invoice read that a new cat was supplied and an fitted as well as two o2 sensors and the p0420 code was read and cleared. Two days ago the check engine light has came on again. This time, I have an OBD-II reader and plugged that in. The reader showed one error code, p0420, the same as last time. So as it stands I am potentially looking at the replacement cat having failed only 13 months on from being fitted. I'm hoping that someone can help shed some more light on this situation for me so that I am not spending over the odds on repairs that are not needed. As far as I am aware, the cat is aftermarket. I was wondering if these come with a specific kind of warranty with them? (I asked a different local garage yesterday and was told that most exhaust parts should come with a two year warranty - is this true?). If it is covered under warranty, is it for the garage who carried out the repair to replace at no extra cost or would I have to pay the labour? Is there anything I can try out first before paying for another repair? Is it okay to drive still and is it worth taking it out on a drive to try and clear it if anything has built up? Are there any checks I can carry out to try and single out the problem? Thanks!
