Monkey 0 Posted April 25, 2007 CO2 too high, Lambda too low apparently. Peugeot 106 XSi 1.4 Anybody got any thoughts? New Lambda sensor, new(ish) CAT, ECU 3 years old, engine has £500 bill from 3 years ago for top overhaul. How do I get those amounts sorted? Share this post Link to post Share on other sites
Richie-Van-GTi 71 2 Cars Posted April 25, 2007 how far out were emissions? If its just a small amount then redex and a good blast may sort it, if they are way out then a new lambda. buypartsby do nice cheap generic ones that do the job just fine. Share this post Link to post Share on other sites
Monkey 0 Posted April 25, 2007 Already fitted brand new lamda! Im thinking redex, go for a good 'spirited drive' and use up all fuel, then fill with tesco 99 stuff and cross fingers I was just hoping somebody might have miracle solution Share this post Link to post Share on other sites
Richie-Van-GTi 71 2 Cars Posted April 25, 2007 raising the idle often helps Share this post Link to post Share on other sites
ablister 31 Posted April 25, 2007 can't raise idle as idle speed is tested. Change the oil and getting one of those engine flush things usually works. Also give the engine a good blast before it gets tested again to get the cat as hot as possible. Lambda too lean could be caused by air leak, quite common around the lambda probe socket on exhaust on tu engines Share this post Link to post Share on other sites
Monkey 0 Posted April 26, 2007 Can anybody tell me how the Rev counter on the 106 works? It seems very wrong on this car. If the same thing telling the counter is telling the ecu the revvs it would explain alot. Share this post Link to post Share on other sites
Guest cknotty Posted April 26, 2007 I would have thought it comes from crankshaft position sensor, at the bottom of the engine, by the flywheel. From the wiring diagrams, wires 132 and 133 come out of it and go into the ECU. The rev counter wire 426 comes out of the ECU and then on to the rev counter. Having said that, if there is no signal coming from the crankshaft position sensor, then the engine would not fire as the ECU wouldn't know the engine is rotating at all. Perhaps yours is either misaligned or on the way out? Hope this helps Chris Share this post Link to post Share on other sites

Monkey 0 Posted April 26, 2007 This one is too Utter pain it is! Planning on head rebuild this weekend I think Share this post Link to post Share on other sites
Guest cknotty Posted April 26, 2007 Good luck! If there is anything you want to take a look at on mine, as you're not that far from me drop me a PM and we can sort something out... Chris Share this post Link to post Share on other sites
Monkey 0 Posted April 26, 2007 Thanks very much, will let you know on that one If you like boats, might be able to arrange some sailing in return on my boat Share this post Link to post Share on other sites
Rob Thomson 6 Posted April 26, 2007 Personally can't see how CO2 and Lambda problem can be anything to do with the head needing a rebuild. Got to be something wrong with the injection or exhaust, surely? Wouldn't it be easier to find a slightly dodgy MOT tester? Share this post Link to post Share on other sites
Monkey 0 Posted April 26, 2007 I could really do with that to be honest... If anybody would like to advise me of good MOT place I would me happy to receive their PM. Cant see anything wrong on injection side, is running totally fine... Could be another exhaust blow I suppose, that would cause it! Share this post Link to post Share on other sites
welshpug 1,657 Posted April 26, 2007 i've had a few cars that run fine but fail the MOT on emissions, one was a tweak of the AFM, the other was a fooked Lambda sensor. Share this post Link to post Share on other sites
Monkey 0 Posted April 27, 2007 Any ideas about servicing AFM on this 106 XSI? It would explain alot Share this post Link to post Share on other sites
