Winthattt Posted October 6, 2020 Share Posted October 6, 2020 Does anyone know the part number of the lambda sensor for a 2014 Sigma engined car, it's a vtti engine?Caterham do not appear to have them in stock but I expect my local motor factor does.

SM25T Posted October 6, 2020 Share Posted October 6, 2020 Remove it and note the etched number on it. Buy from parts supplier on line. Link to comment Share on other sites More sharing options...
paul_w Posted November 23, 2021 Share Posted November 23, 2021 bumping this as I've not been able to find it and can't see anything written on the sensor itself. Pretty sure from previous threads it's faulty - mine a 2010 fixed cam Sigma upgraded to 140bhp - MoT runs out this week and on Saturday it started missing once warmed and the revs going up and down at idle, so a quick lambda swap might cure it given I've only a couple of days to do so and there's a lot of threads pointing to the lambda going on Supersport cars.

Dave connors Posted November 23, 2021 Share Posted November 23, 2021 Changed the lambda on my 2011 supersport (fixed cam sigma) the number was 0258 006 600 (bosch) Link to comment Share on other sites More sharing options...
paul_w Posted November 23, 2021 Share Posted November 23, 2021 Thanks Dave, I'll try to hunt one down Link to comment Share on other sites More sharing options...
Adamc456 Posted June 13, 2022 Share Posted June 13, 2022 Reviving this thread as I am trying to find a lambda for mine now, its a fixed cam supersport Sigma engine. There's nothing etched onto the sensor itself. Googling the part number 0258 006 600 above doesn't return any solid results. Link to comment Share on other sites More sharing options...
Amos91 Posted June 13, 2022 Share Posted June 13, 2022 Check the plug on yours, but this design looks very familiar - Bosch 0258006155 - Lambda sensor with vehicle-specific connector : Amazon.co.uk: Automotive Link to comment Share on other sites More sharing options...
Amos91 Posted June 13, 2022 Share Posted June 13, 2022 Alternatively, Sevens & Classics sent me a new lambda just after I bought my 2008 Sigma due to a running issue.They sent me this one - https://www.opieoils.co.uk/p-175710-lambda-sensor-febi-bilstein-21383.aspxBeen fine for over a year now.

Adamc456 Posted June 13, 2022 Share Posted June 13, 2022 Thanks for your help, the first one definitely seems to look right. That second one looks a bit different but if it works it works! Link to comment Share on other sites More sharing options...

Reindeer Posted June 19 Share Posted June 19 Sorry to bring up an old thread but don't want to start another lambda part number thread! Does anyone know which one it is for the Sigma 150....? There's nothing at all on my current sensor.... Thanks All! Link to comment Share on other sites More sharing options...
Eccles Posted June 20 Share Posted June 20 Hi, this is the info on my sensor..... Link to comment Share on other sites More sharing options...
Andy135 Posted June 20 Share Posted June 20 And here's mine. Link to comment Share on other sites More sharing options...
Reindeer Posted June 20 Share Posted June 20 Thanks Gents. Interesting they're both different. I'm guessing both they didn't change the lambda as part of the 150 upgrade.....? I'll do some digging! Cheers and thanks. Tom Link to comment Share on other sites More sharing options...

It'll be the same as the other Sigmas. 1 Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted June 21 Member Share Posted June 21 It's worth recording these as text so that they can be found in the future. I think that those are: 0 258 010 319 which is almost a Bosch part number and 0 258 006 599/600 which are Bosch part numbers. Jonathan 1 Link to comment Share on other sites More sharing options...
Reindeer Posted June 21 Share Posted June 21 Apparently this is the latest Bosch number....0258006605 And....that has then been replaced with 1303221.. I've ordered one. Will let everyone know how it goes! Link to comment Share on other sites More sharing options...
Reindeer Posted June 21 Share Posted June 21 The 599/600 was discontinued... Link to comment Share on other sites More sharing options...
