karlosR 3 Posted March 27, 2015 Report Share Posted March 27, 2015 (edited) I keep getting constant faults on my Bora 4 motion. scanning for fault codes I get 17511 & 17516. I know these are for..... 17511 - Oxygen (Lambda) Sensor Heating: B1 S1: Performance too Low17516 - Oxygen (Lambda) Sensor Heating: B2 S1: Performance too Low my question is this. which oxygen sensors are they? are they the pre-cat lambdas? I don't know if all four sensors are the same so ideally i'd like to avoid buying all four if I can. thanks! Edited March 27, 2015 by karlosR Link to post Share on other sites

karlosR 3 Posted April 1, 2015 Author Report Share Posted April 1, 2015 (edited) thanks, i'm getting cheesed off clearing the codes on a daily basis..... serves me right though for using supermarket fuel I suppose! I've decided to run shell nitro+ and it is now running a lot nicer & more economical too. anybody got any experience of this? http://www.terraclean.co.uk/ if it does what it says then it should clear 120k worth of cack out of the car so will hopefully run cleaner.

karlosR 3 Posted April 9, 2015 Author Report Share Posted April 9, 2015 Dora the Bora is running better on shell Nitro+ but i'm still getting the CEL on the dash. i'll just have to bite the bullet and replace the lambdas..... along with the G200 sensor, oil level sensor to go with the brake fluid change and oil change. the exhaust is starting to sound ropey to..... I think the Terraclean will have to wait a while! Link to post Share on other sites
MJ Vr6 79 Posted April 10, 2015 Report Share Posted April 10, 2015 This could also be a problem with your Cat. As it can be blocked and causing Back Pressure.Have you VagCom'd it.Its not always the sensors to be at fault.I have the same problem that has come up, I had changed sensors earlier this year.

karlosR 3 Posted April 13, 2015 Author Report Share Posted April 13, 2015 i'm thinking about getting a twin 200 cell cat made up. decat would be a pain in the rear come MOT time & without a stage 2 map i'd still have the annoying yellow warning light on the dash. Link to post Share on other sites
