My Check engine light comes on under load going up a certain steep hill near me then goes off after 20 seconds.

oem ecu
pod filter
decat downpipe and 2.5 system
all the vacuum lines have been changed for blue ones so dont know if theres a restrictor pill or not.

 

Get the codes looked at. Mine did this and it was the first lambda sensor in front of the turbo cost me about £35 of ebay.

 

will a obd reader pick up on the codes?

 

it should do.

 

Obd reader wont work on an my99. Connect the diagnostic plugs under the steering column instead to read it

 

I will give it a try

 

it will be the lambda sensor. Had the same on my MY00 sport. Under load check engine light came on. Went away after a while. Car will run rich until the sensor is replaced and will be hesitant if left for too long

an easy fix

 

It is the Lambda sensor just done the CEL thing and got error code 32 Oxygen Sensor or Circuit (No. 1, Right Side, On SVX). Is this the one closest to the turbo?

 

Yep you only have 1

 

I thought I had a pre and post cat lambda

 

I had the same thing years ago on my classic no mods apart from an induction kit seem strange when the light came on going up hills turn out it was the maf sensor

 

no you only have 1

 

nice one were's the best place for a replacement
