There have been a few threads on using biodiesel in SEATs - thought this bulletin from SEAT might
help clarify the situation
SEAT’s TDI engines are unaffected by new legislation on biodiesel in the UK.
The legislation, introduced on 15 April, makes biodiesel a mandatory component in diesel fuel offered at UK pumps. But the ruling, which forces fuel suppliers to use at least 2.5 per cent biofuel in diesel production, does not
change the current situation at SEAT, which approves the use of diesel fuel containing up to five per cent biodiesel in all of its diesel vehicles, the same amount allowed in the UK by motor fuel standard BS EN590.
BS EN590 fuel is also approved for vehicles fitted with a Diesel Particulate Filter (DPF).
SEATs currently have a ‘No Bio Fuel’
sticker on the inside of the filler flap, which relates only to fuel with a biodiesel content of more than five per cent, including 100 per cent biodiesel. None of SEAT’s current production vehicles are suitable for use with 100 per cent biodiesel, which will decrease engine durability and invalidate the manufacturer’s warranty.
100 per cent biodiesel - A number of older SEAT models are approved to run on 100 per cent Rapeseed Methyl Ester (RME) biodiesel, which is available from a limited number of specialist suppliers. Where 100 per cent RME biodiesel-compatible parts were fitted during manufacture, the vehicle PR code (found on the data
sticker) is 2G0. However, some older vehicles may not have this PR code. Always refer to the owner’s handbook and factory information regarding the vehicle’s compatibility with biodiesel before using this fuel type. In vehicles that are 100 per cent biodiesel compatible, SEAT has only approved the use of Rapeseed Methyl Ester (RME) to standard DIN EN14214. No other biodiesel can be used. Additionally, no other diesel substitutes, especially any type of cooking or industrial oil, should be used as fuel in any circumstances.
Summary
• Vehicles that do not have the factory preparation for biodiesel cannot use 100 per cent biodiesel.
• Vehicles fitted with a common-rail fuel injection system cannot use 100 per cent biodiesel.
• Vehicles fitted with pumpe düse injectors cannot use 100 per cent biodiesel.
• Vehicles fitted with a Diesel Particulate Filter (DPF) cannot use 100 per cent biodiesel; however EN590 containing up to five per cent biodiesel is approved for use with DPF.
• 100 per cent biodiesel vehicles cannot be used in temperatures below -10°C.
• The use of 100 per cent biodiesel may slightly reduce the driving performance of the vehicle and slightly
increase the fuel consumption.
• The use of 100 per cent biodiesel may mean the vehicle needs to be serviced more frequently.
