been fighting a loosing and expensive issue with my 03, AUQ, 1.8t Leon Cupra. I know this is ASN but the likes of tuffty, prawn, klappe, badger5 are all on here and not to discount anyone else but you guys seem to know the 1.8t inside and out !!
I have posted a few time with this issue and not really got anywhere, but today l was getting a small weld on my backbox done and noticed something new !!
There are 2 lambda sensors on this car, but the 1 in front of the cat has a massive long cable ?? Its been tie wrapped up so as not to hang down, but surely this cant be correct !!
So my question is, if its the wrong lambda sensor could it cause a hesitation around 2k revs??
No codes at all, mpg down a little 22.4mpg on a short city run(just changed thermostat tho)
