Yeah the ecu was mapped and EGR was blanked off, and I’m not entirely sure what was done to the DPF. i May invest in the tech stream software. i did read somewhere that the DPF provides a little back pressure to the turbo and maybe that has something to do with it but I’m not so sure. The turbo works perfectly when it operating. Apart from the standard turbo lag on these cars it kicks in around 1700/1800 RPM and pulls the car nicely. The 5th injector hasn’t been touched yet but I doubt that would have any input on this fault

The wastegate seems to move free, but if it was this wouldn’t it happen as soon as the turbo is used? Because it’s much more random than that. would this also cause a warning on the dash? And would it have an input on the cruise control selection? It just seems strange because even if you go into ‘limp’ mode I’m sure you can still operate the cruise control light so I’m not sure what’s causing that to stop working when I lose power? the problem goes away when I turn the car off then again

Hi there, firstly can I say what a helpful forum this is! so the problem, I own a IS220D 2.2 and like a lot of people I’m starting to have a few problems. Firstly the EGR valve was blocked and the DPF wouldn’t regenerate. So I have had the DPF removed and the EGR valve blanked off. However, my problems start here. The car will randomly lose all power and will struggle to get above 2500 revs. Exactly the same symptoms as ‘limp’ but with no warning lights or anything on the dash? The only thing I have noticed is The ‘cruise control’ light in the dash will work fine until the problem occurs and then it will turn off and I can’t turn the cruise control on again. Other than that, no other symptoms... i have loosened the turbo off and used Mr Muscle (as well as revive turbo cleaner) thinking I had sticky veins or wastegate problems but it still hasn’t cured it. Any ideas anyone? Thanks
