I've just had a frankenturbo exhaust manifold fitted on my s3-bam only to find the the pre cat lambda sensor won't now fit.
There's not enough room in between the 3" relentless downpipe and the manifold !
What are my options ?
Can I get shorter sensor ?
Can I use one of them 90° elbow sensor spacers to angle the sensor down ?
Or would it work if I put the pre cat sensor where the post cat sensor should be ? Extending the wires if needs be. (As the car has had the rear/post sensor mapped out already) thanks in advance, really stuck here as this needs sorting asap :-(
