Lambda sensor

[Jonzy]

Is there anything that I can log in vagcom that will showup a dead/dying lambada sensor.

Theres no fault codes stored. MAF is 2 months old and gives expected values. My fuel consuption is awful and its been suggested that a lambada sensor my be at fault.

Haven't got a clue mate - but I do know it's a Lambda sensor, and not a Lambada! Don't worry we use a 'Lambda' print machine at work, and quite a few people call it the Lambada

I thought it was, never remeber how to spell it! Cheers Mart, will give it a go later!

An engine Fault light should come up and your mpg will fall through the floor

 

[Jonzy]

No engine light, but mpg is hovering around 20-22mpg depending on the petrol. And thats taking it easy, doesnt really move wether I hammer the car or drive like a granny.

Jonzy, get those blocks logged and all will soon become clear

 

[Jonzy]

Doing it tonite fella, will post the results.

First is showing a constant 0% on both sensors, the second log is the last bit of my drive home. Noticed that both sensors are showing negatives?

I aint got a clue what im looking at!

 

[Martyn]

Sensors look fine to me

 

[Jonzy]

So just **** fuel economy then

 

[Martyn]

Maybe you've just got a lead boot

Clean the MAF with some IPA bud.

 

[Jonzy]

I wish I could put my foot down but im stuck @ 50-60mph most days back and fore to work. Only time I get chance to open it up is weekends @ night. Even then its still returning 20-22mpg.

MAF is a month old, and its been the same since I put it on the car. Oh well.

 

[Martyn]

Where did you get the MAF from mate?

My Ibiza will happily do 35mpg, even when I thrash it it's hard to make it go below 29!

 

[Jonzy]

Eurocarparts, genuine bosch exchange unit. Part number matched the old one. I drove from Cardiff > Reading > Bath > Cardiff. 70-80mph and it peaked at 26mpg!!!

 

[Martyn]

Do you have any other mods mate?

 

[Jonzy]

Dynatwist, 007P, Forge FMIC, shonky powerblow bean can excuse for an exhaust (being changed when my supersprint finally arrives!)

 

[Martyn]

Interesting....... thinking back to 'pre-revo' I was only really getting 27ish mpg with similar mods....

 

[Jonzy]

Im planning on getting it remapped after ive got a milltek dp/cat and the supersprint fitted. Maybe a 90k service and 4bar too

Lets hope its just **** standard software!
