Volkswagen Motorsport announces technical fix and update for Polo GTI R5

2018 Volkswagen Polo GTI R5

After a spate of Polo GTI R5s unexpectedly and suddenly catching fire – the most recent incident featuring WRC2 star Ole Christian Veiby at last weekend’s Rally Portugal – Volkswagen Motorsport has announced that a technical update will be applied to current customers’ cars.

After consulting with experts, the Hanover outfit states that the problem appears to lie with the position of the safety valve on the fuel tank, which must be adjusted. After the solution has been tested, all cars sold so far will receive the update free of charge. In the meantime, teams who currently run the 270bhp machine have been advised of the findings and have received fuel and check recommendations. The full official Volkswagen Motorsport press release issued today is reproduced below.

Update for the Polo GTI R5: customer cars will be revised
Volkswagen Motorsport is working flat out on a technical update for the Polo GTI R5, after multiple customer cars suffered fire damage at rallies in recent weeks. Working together with experts and consultants, Volkswagen Motorsport has thoroughly investigated several of the cars affected and has already developed technical solutions based on the results. Tests have been arranged at short notice. Once these have been completed, all customer cars will receive the update free of charge.

The investigations revealed that the position of the safety valve on the fuel tank must be adjusted, as its function may be restricted when using a specific fuel. In some instances, the fuel cell breathing system becomes blocked, resulting in ‘over’ pressure. Together with the heat from the exhaust, this ‘over’ pressure can cause a deformation of the tank cover. This can ultimately result in contact between the propshaft and the exhaust, ultimately causing damage to the fuel cell system.

Based on these findings, Volkswagen Motorsport has developed a technical solution. The plan is to reinforce the tank cover around the propshaft and exhaust with a steel support and to optimise the insulation. The fuel cell breathing system is being modified, in order to reliably regulate any possible ‘over’ pressure. Furthermore, the clearance between the central exhaust and the tank is to be increased.

All these measures will be tested in good time and in realistic conditions. Once they have been successfully evaluated, all Polo GTI R5 will receive the update free of charge. Customer teams have already been informed of the procedure and have also received recommendations for suitable fuels and regular checks on their cars.
