MAN admits to fixing 300 faulty Euro-5 D26 engines
MAN has admitted that to date it has repaired or completely replaced nearly 300 early Euro-5 EGR 12.4-litre D26 engines in the UK because of EGR cooler and/or high-pressure intercooler faults.
The necessary work has been conducted free of charge and regardless of warranty status, said MAN – assuming that its maintenance recommendations have been followed and its service consumables used.
However, aware that other early D26s may fail too, the truck maker appointed a specialist at its UK head office in Swindon to interpret the results of a nationwide oil analysis programme that has been conducted to help it identify the warning signs as early as possible.
The manufacturer’s dealers have received extra training to help them spot potential faults as part of what MAN describes as a five-stage plan to handle the problem.
The plan involves the company committing to support operators with D26 engines – including dealing with any consequential damage – for five years from the first registration. That is provided the truck concerned has not covered more than 1 million km, that MAN parts and service consumables have been used, and the company’s maintenance guidelines adhered to.
“As a result of all these measures we have significantly reduced the impact of this issue,” a spokesman for the manufacturer said.
“We are now focused on ensuring that all affected vehicles are brought up to a quality-assured standard.”
The company has not disclosed how much the measures have cost so far. Acutely aware of the potential damage to residual values and that uncertainty over the reliability of a vehicle is likely to dent its second-hand appeal, MAN stressed that all Euro-5 D26-powered TopUsed trucks have undergone stringent engine checks before being offered for sale.
