Hello all,
I've been lurking on the forum with nothing much to say lately; I've been fooling around with a lot of Fifties and Sixties machines, and my Noughties vehicles have been pleasantly boring (from the maintenance perspective).
This weekend I put several hundred miles on the Sprinter, from highways to country roads, as I noodled all around central Texas picking up various components for my next project car. Temperatures were cool for a Texas summer-- hardly got above 96 F -- and the Sprinter didn't miss a beat. 21-22 mpg the whole way.
This afternoon, after about an hour on the road, I got a check engine light. No noticeable symptoms or anything otherwise out of the ordinary. I stopped at Autozone for a quick scan and got the code; I didn't have time for much more than a brief visual check under the hood after that before I parked up the van at the workshop, but didn't see anything amiss in the engine room.
The code was P2457 EGR Cooling System Performance. According to Autozone's system, this means that the intake air temp (IAT) sensor has gone over a set temp for >30sec, with possible causes including 1) restricted air to the CAC (intercooler) system, 2) damaged CAC, and 3) "tubes off or damaged."
I'll likely take it in to the dealer in the next few days, but wanted to ping the list to see if anyone else had seen this and, if so, what the diagnosis was. I will follow up once I have some news from my end.
Thanks, and happy Sprintering!

PS- I got all kinds of comments on the van during the trip; now that someone has said "nice truck" to me at the gas pump, this West Coaster feels like a REAL TEXAN. But I do sometimes feel like that three-pointed star attracts a little too much attention...
