My Check Engine Light came on a week or so ago on my 2005 with 98,000 miles on it, so I brought it into my local Dodge dealer. They found the truck was throwing Code PO243 - Wase Gate Pressure Control PWM and told me they would have to replace the entire Turbo at a cost of around $2400. I have a fairly comprehensive extended warranty on the truck, but the warranty folks refuse to cover the turbo. Turbo itself seems fine - spools up, not loose. I've read posts on this error code here, and it sounds like I just need to replace the Waste Gate Control Valve, which I can get delivered to my door from Hoesli Diesel for around $270. Dealer technician checked for loose or frayed wires and found none - they look OK to me as well. Should I order the control valve? How hard is the install?
