Hi guys, I'm in serious need of help. Recently the car has started to play up when it's warms up. First it just wouldn't start once it was warmed up and I be cranking over for ages and I could smell the fuel not being burned. So I change fuel pump resistor 109 and 167(I think) and also I fitted a new Bosch cam shaft sensor since the symptoms of a doggy cam sensor seam to be when it's warm. So now its gotten worse. When driving now it suddenly hesitates and then it feels like someone slams on the brakes. And it then slowly but surely cuts out and I have to pull into the hard shoulder. And try and start it again, which takes five minutes. Have had it on vagcom and it is showing no fault codes. Could it be a dieing knock sensor. Help is really appreciated. Car is mapped with joe power remapping too. And has over run mapped in. So was thinking this with a broken knock sensor will be the main issue. Oh Ye is a mk4 Ibiza cupra petrol.
