Df037 Renault |top| – Verified & Certified

: In many engine management configurations, DF037 points directly to a fault in the stop contactor circuit (P0571). This can affect cruise control, start/stop functionality, or trigger a "Braking System Fault" warning.

The DF037 was also notable for its reliability and durability. The car's engine and transmission were designed to withstand the rigors of rallying, and it was not uncommon for the DF037 to complete rallies with minimal mechanical issues.

In many Renault models, especially the Scénic II and Grand Scénic, DF037 signifies a "Loss of ABS multiplexed transmission". This means the ABS computer is failing to send vital data (like individual wheel speeds and braking pressure) over the vehicle's Controller Area Network (CAN) bus to the main computer and other systems like the transmission and parking brake. This failure causes a cascading system failure, leading to multiple symptoms.

Next, power and torque figures. The turbocharged versions (DF037T) would have different specifications compared to the naturally aspirated (DF037D). The naturally aspirated version I remember produces around 55-60 horsepower, while the turbo is about 70 hp. Wait, I need to be precise here. Let me cross-reference. For example, in the Renault 19 and other models equipped with the DF037T, I think the power is approximately 74 PS (73 hp) at 4,000 rpm with torque around 125 Nm at 2,000 rpm. The naturally aspirated might be lower, maybe 55-60 hp. Let me confirm that. Yes, DF037D is 55 hp (41 kW), and the turbo is 74 hp (55 kW). Good.
