renson 0 Posted December 3, 2007 was fixing gas analysers on friday and decided to test them on my car. was a mistake as the car failed the BET test and the full cat test too. 02 and HC were fine but the co read 0.6 (should be 0.30) and lambda was 1.034 ( should be 1.03) Decided to check the ecu for fault codes and found the following; 00537 lambda control-regulation g limit exceeded 00520 air mass/ flowmeter-g70/g19 Sporadic: open short circuit to earth 00587 adjustment limit mixture regulation: adaption limit exceeded autodata said chek the earth on the inlet manifold but the only earth i can see is by the distributor.anyone had any of these problems before? don't think the cat is at fault but possibly the lambda sensor. anyone know a good supplier to get one from, don't mind if it is universal fit? also got ABS fault codes as; 00532 supply voltage 00285 speedsensor front right-g45 00287 speedsensor rear right-g44 don't want to get 2 sensors if abs unit or something simple is at fault. maybe it would be worth keeping a full list of trouble codes and suggested fixes for them Quote Share this post Link to post Share on other sites
