After months of searching, I finally bought a Sprinter. The price was right, one owner, 153K miles. 2005 140 cargo van. I drove from Taos to Phoenix on my motorcycle, bought it, loaded up the motorcycle, and headed back to Taos. I took a bit of a risk with the purchase. The Sprinter was in limp mode, couldn't get over 60mph, and I was told the codes read "high and low fuel pressure". But the price was low enough that I was ready to spend a few thousand on repairs and still feel like I got a good deal. Driving back to Taos, I almost made it to Santa Fe (60 miles from home) and after refueling, the van wouldn't start. AAA tow truck to Santa Fe, in the hands of competent mechanics (I believe). They ran tests and made recommendations, resulting in: serpentine belt replacement, replaced all glow plugs, new fuel pump. Now the sprinter runs, but still in limp mode. After diagnosis and other testing ($$$), codes P0088 (high fuel pressure at the fuel rail) and P2601 (low pressure at the fuel soledoid) show up. These are probably the codes that have been there for a while. Also, they found a failing turbo resonator (boost pressure leak). They are quoting $1630 parts and labor to replace the rail and solenoid . I have already bought a Dorman turbo resonator replacement already. I was prepared to sink some cash into this sprinter, and I want it to be tip top mechanically before I start converting it into a camper, but am I on the right path here? Or is this a rabbit hole that may empty my bank account?
