I thought rotating tyres was a thing of the past due to tyres having to be fitted a certain way, that's why there's a directional arrow on them and if TPMS is fitted the wheel has to stay on the same axle it was fitted too.
I took my EGR valve off and cleaned it, but this has now been some years ago ! I did check if the plunger inside worked when under vacuum, lucky for me ive only had a few little issues which I have managed to fix myself. the last time I had bad smoke and lack of power was my boost pipe had blew off from the intercooler due to a jubilee clip had rusted,
Hi Peter, Many thanks for replying.
I saw one of your previous replies to another member on here advising the use of Millers Eco Plus so I have some ready to use as soon as I fill up with fuel.
I have tried the Wynns EGR cleaner with some intermittent success, but I was advised to use Millers Diesel Power Eco plus and it has worked a treat as I have had the code P0402 only once, and a quick squirt into the fuel tank did the job and it took just about 5 minutes running the car. Worth a try.
