Car experts warn of ‘failure epidemic’ on this part – what you can do to protect your car

Only using a car for a short ten or fifteen minute journey could see a vehicle’s Diesel Particulate Filter (DPF) block as the part requires long journeys to clean this. Motoring experts have warned the UK could face a DPF failure epidemic as cars will not have been run efficiently.  

James O’Malley, spokesperson for Select Car Leasing said: “The filter does a brilliant job of stopping soot passing into the atmosphere, making your car more eco-friendly. 

“But the trade-off to enjoying a frugal diesel is that the soot caught in this filter has to be ‘burned off’ in order to regenerate the DPF. 

“And the best way to burn off the soot is to make sure you regularly treat your car to a good 30 to 50-minute blast on the motorway at sustained speeds. Short runs are the sworn enemy of the DPF.”

Long journeys are essential because DPF’s usually regenerate when the exhaust reaches a certain temperature.

Mr O’Malley said: “There’s a number of ways you’ll know you’ve got a DPF problem. 

“You might see a filter-shaped warning sign on your dash, you might notice stilted performance or strong smell from the exhaust, or your car might even go into limp mode. It might not start at all.

“And remember that if there’s a warning light on the dash, it’s an automatic MOT fail.”

Motoring experts at the RAC have confirmed short journeys at low speeds are the prime cause of DPF failures. 

How to fix the issue without driving? 

Some garages can clean a blocked DPF through a process known as forced regeneration. 

This is not a guaranteed fix but is usually successful in clearing the majority of excess soot. 

This will enable the part to automatically regenerate itself again once the car is back on the roads. 

What other car issues may I face?

According to AutoTrader car batteries are likely to die if a car is not driven for between 12 and 16 weeks.

Car alarms can drain the battery and AutoTrader urges road users to disable this if your car is parked in a safe place such as your garage. 

However, the motoring experts say the best option is to buy a trickle charger and regularly top up the battery.

A smart charger can be plugged in all the time and will only top up the car battery when it is absolutely essential. 

This will help keep a car in good condition until the vehicle is ready to be used again once travel restrictions are lifted.
