UK-POLOS.NET - THE VW Polo Forum

Hi All,

I have vw polo 1.6 16v gti, MKV 6N2.

Recently, my engine management light started coming on and off and after VCDS inspection it was lambda sensors. but they are really very expensive to buy around 80 to 90 quids.

Then I found the zirconia lambda sensor's on ebay for only £17.80 (Genuine Bosch Universal 4 Wire O2 Oxygen Lambda Sensor ) the wiring colours on my sensor (on manifold down pipe in engine bay) is red, yellow, black and white.

Ebay Link : http://www.ebay.co.uk/itm/Genuine-Bosch ... 2589bdc47d

Not sure if this will be good for my car? any ideas?

There is alot of fake bosch sensors around at the moment. I would only get a genuine one from VW/TPS or from the likes of Euro/GSF.

if however it is a genuine offering, and the wire colours match, it should in theory work

Thank you Alex.. I will stick with you advice....
