  • Emissions mot failure after remap and milltek cat

    I spent most of today shitting myself about my car. Mot failed this morning because emissions were very much over where they should be. Thought I'd have to take it back to the remap place in Newcastle tomorrow as mot expires tomorrow! Luckily turned out just to be the lambda sensor! Just in case this happens to anyone else!
