Diesel Emissions Irregularities Uncovered By Real World Testing

Diesel Emissions Irregularities Uncovered By Real World Testing

Is there a common thread that links all these diesel emissions shenanigans? Apparently there is. The exhaust gas recirculation control systems used on all those engines were all manufactured by Bosch. At issue is whether those systems were programmed to shut off under certain conditions, especially at lower air temperatures. Reportedly, Mercedes programmed its system to turn itself off below 50 degrees F. The controls on Opel diesels were deactivated below 62 degrees F. Testing in the UK showed that diesel emissions were typically six times greater when the systems were deactivated.
