Currently having a problem with my MY00 PPP, where the boost seems to cut in late and all of a sudden between 3 / 4 thousand RPM (boost guage , and fuel ecomony is worse than usual!! Having done a bit of a search it seems that the Lamba Sensor could be failing. Does this sound right?

Assuming it is, are these cheap to replace, and is the job a DIY one???

Thanks


Pete

 

not sure if its the lambda failing or not, but could possibly be the Maf sensor

Lambda is around 120 quid from a main dealer, Maf (sensor only) is around 75 quid from a dealer

When my lambda was failing, my car drove fine, and came on boost fine, it was just lacking in performance, but as it had degraded over a period of time, I hadnt really noticed until I drove behind another scoob, and couldnt keep up (same mods as me at the time)

 

Cheers sonic,

Had the MAF changed a month or so back.

The car is OK, just seems unresponsive and it needs to be 'forced' along instead of previously it would accelerate alot more eagerly at medium boost...

 

Could be lambda then, difficult to test really without Delta Dash/AFR Gauge or a passenger willing to look at a multimeter attached to the lambda wires whilst you drive on WOT

I found it easier just to change the Lamdba, job sorted

 

is the Lambda an easy enough job to change then??

Also being stingy, are there decent options available instead of the dealer??

Cheers again

L300 lamda from Halfords for £25 does the job, if they still stock them....believe they've started to phase them out recently.

 

Cheers Mica,

I'll pop over to halfords tomorrow.

Best colour by the way!!!

 

the only thing with the Halfords Lambdas, is that the connectors are different, and that you have to chop it off, and chop off the OE connector and join them up

You cant solder the wires either, as they are stainless

 

Ah, so would be out with the gaffer tape then!!

Anywhere else to get the proper ones??

there isnt a problem using the halfords one, ive had one in for 20k miles

just a bit of a pain having to swap the connectors over

 

I'll give it a whirl then!!

Cheers againfor your help!!
