Re: Having trouble finding a fuel temperture sensor on a t4 2.5 tdi transporter? Can anyone help – 15-07-2011, 01:29 PM. The fuel temperature sensor G81 is in the fuel pump, the part number is 028 906 040 C and they cost just under £20. Officially VW say that the pump has to be replaced to change the sensor BUT if you have the special Bosch my vw transporter t4 2.5 tdi w reg stopped working yesterday…. transporter. 2000 Volkswagen transporter t4. Already Tried: rac was called and he diagnosed that the diesel pump was not working, the fuel filter has been changed, ps when engine was restared their was a lot of pinking and the accelerator was not responsive and a lot of white Data from the 5-Cylinder 75kW VW T4 TDI Engine: Bosch VE VP 37 Fuel Injection Pump Injectors - Bosch P442-----Data from the 5-Cylinder 111kW T4 TDI Engine Bosch VE VP 37 Fuel Injection Pump Injectors - P764 Injector - Dual Spring version, minimum dead volume Lift I : 0.06mm Lift II : 0.25mm Nozzle P-type, VCO-nozzle Hole dia. 5 X 0.216 mm The 02G TDI Gearbox. For the 5-cylinder 2.5 litre ACV (102bhp/75kw) TDI engine launched in August 1995 on the T4a, VW provided the stronger 02G gearbox. Unique to the high power T4's, this gearbox is more able to cope with the extra torque generated by these state of the art engines. The Audi based ACV engine was initially the most powerful Model: VW T4 Transporter. Engine Size: 2.5 TDi ACV (75kW @ 3500 RPM : 102bhp) Torque: 250Nm (184 lbf.ft) at 1900 - 2300 RPM. Weight: 2890kg GVM (including weight of engine and fuel tank etc.) From the engine specifications for an ACV, a Tesla motor would be perfectly suited for the torque requirements, however there would be a requirement to Assuming the same deck height, T4 AXG-engine code pistons (VE injection) yield a CR of 19.0:1. T5 PD pistons bring it down lower still. The formula for determining the compression ratio is:\. CR = (clearance volume + swept volume) / clearance volume. For a stock bore- and stroke 1.9 TDI, each cylinder will have a swept volume of 474 cc (492 cc Its selling for 4500£. Mileage is big though and that worries me. Here are the specs!

Engines There was a choice of two different diesel engines in the T5, producing a total of four different power outputs; the 1.9 PD offered either 85 or 105bhp, while the more torquey five-cylinder 2.5-litre was available in 130bhp or 174bhp guise, the latter getting the option of VW’s 4Motion four-wheel drive technology. eEwIT.
