Mechanically faulty near closed position; 272F00 - Exhaust-gas recirculation valve plausibility. Posts: 154. 35d worsening gas mileage - solved- thermostat/fan/EGR cooler - DIY with pics. I have a 2010 e70 35d with about 79,000 miles. Over the past 6 months or so I've noticed a drop in highway mpg from 31-32 to approx 25-26.

Hi I am a new member, so much great info on here! I have a 2010 X5 35d, 117,000 miles. Has been a great vehicle so far. I recently got the code P2457 for egr cooler efficiency. I inspected the exhaust cooler and there doesn't seem to be any cracks or leaks with the engine running. Coolant level is good.

2012 X5 35d with 120k miles. Original owner and overall rock solid SUV. CEL came on and through the following code on CreoDor C310: 00 01 48 73 No Found!
