lambda

Hi does anyone know if the lambda sensor affects the mpg readout. My mpg readout is all over the place ticking over at 12mpg but accelerating at 27mpg and everything in between. When I lift of accelerator completely still reads 53mpg or 30mpg just depends how it feels cheers Sent from my...

Hi, I have been measuring some blocks and I recognized that I have something weird going on in measuring block 031. I have an AWM engine so 031 shows actual and requested lambdas. So my actual lambda is usually within spec, but sometimes it is way off. I see a lot of 1.991 and some 1.6xx, 1.4xx...

Hi all, Not sure if i've replaced a faulty part that wasn't the real problem. Started the car and all fine then got a mile down the road then first cough that rapidly built into very bad kangarooing. At tick over the engine was sometimes stalling or reving up to 2k rpm. Had to get it from where...

Hi, My 2nd time posting here. I finally got a VAG tester and was able to pull the error from my 2001 V8 passat. I get the CEL light. I got the following: 17584 . Bank1 : O2S (Lambda) Correction Behind Catalyst: Control Limit Reached. I know there are 4 sensor but don't exactly which one I...

Ok, i'm new to vw world, im getting a code for a "lambda probe" Could someone tell me what this is and what it does? Even better, where i can find one for a 94 vr6. I just went through inspection with new maf, new plugs, new airfilter, new o2 sensor, vacuum lines replaced, and still failed...

2000 V6 ATQ Manual. My readiness code shows all passed. Playing with my Vag-Com, I cannot get Group 107 Field 4 to ever show "ON". Always "OFF". I idle, RPMs are within specified test range, fields 2 and 3 show voltage fluctuates up and down. Is there a trick to get Group 107 to turn the...

Hi! I had some problems starting my 2.0FSI and when I checked the fuses in the engine room i took out a fuse and I think I put it back inte wrong position, because after that the "exhaust" warning indication is shown. Is there anyone that have a hint where the lambda fuse should be? Thanks for...

I was wondering if anyone could help me diagnose my VAGCOM readout. Been getting horrible gas mileage so pulled to code listed below for the Oxygen sensor. I suspect I have to replace it. Is this doable without a hoist? Any input is much appreciated. Regards, Shawn Chassis Type: 3B - VW...

OK - as you may have seen in my earlier threads - my Passat constantly fails on the left bank cat with a low O2 error code. My dealer swears my car has had the known ECU update. So, before I have to splash out on a new CAT (dealer price is £649 + VAT - cheapest aftermarket unit I could find is...

Hi all, long time lurker in need of some help. I am trying to diagnose a 16806 Main Catalyst Efficency Below Threshold DTC. It is probably either one of the 02 Sensors or the Cat. If it is the Cat I'll get it replaced under warrantee, but I don't want to pay the dealer to change an O2 sensor...
