The sheer popularity of the humble DAF LF means there are plenty of operators out there all too willing to point out its faults. There might even be an element of nit-picking going on, especially given these are generally short-distance vehicles whose drivers will be back at base and available to report the smallest of defects at the end of every shift. Seat bases: Seat bases suffer badly from wear, especially if drivers do not use the air dump facility before sliding out of the vehicle.

Rear crank seals: Reports of leaks from rear crank seals on some vehicles. Doors: Door-check straps become worn, with the result that the door catches on the front corner panel and causes damage. Sensor rings: Sensor rings on the braking system can corrode, causing the system to show an ABS fault. The solution is to clean or replace, although beware on older models — these had the sensor cast into the actual disc.

Number plate: The positioning of the front number plate means that it hangs down below the bumper, and as a result frequently gets caught on potholes and entrance kerbs. Engine light: Phantom red engine lights which clear themselves if the vehicle is parked up for minutes, leaving no trace on vehicle diagnostics. The cause is water ingress on the passenger side, below the windscreen. Gear covers: Watch out for timing gear covers, which are prone to weeping.

This leads to incidents where drivers cancel regeneration, either deliberately or by knocking the switch, then forget to turn it on again.

A sprung rocker switch is available, intended for pet-regs trucks, but can be retrofitted to any vehicle at minimal cost. Anti-roll bar: The rear anti-roll bar bushes often wear prematurely. AdBlue: AdBlue faults — some later trucks require the exhaust changing to cure these.

Some reports of front springs breaking in the second or third year when the LF is used as a skip-loader. Gearstick: On earlier, manual models, there are reports of incidents where the gearstick has literally fallen through the dash.

The cure is simple — lift the stick back up again and replace the spring clip which should hold it in place. Clutch: Clutch replacements needed far sooner than expected in some applications — as soon as ,km on one urban-based fleet. Check whether or not this has already been done if the vehicle comes from a similar background. Doors: The rubber door seals have been known to prematurely wear. Steps: Steps only made from fibreglass which are bolted directly to under the base of the cab.

If heavier drivers regularly use the vehicle, these are prone to breaking off.Welcome to world's most trustworthy automotive forum. Thread Rating: 0 Vote s - 0 Average 1 2 3 4 5. Junior Member.

I think only Davie. When we used to fit an emulator to an LF with an active fault we had to flash with Davie to clear the original fault once the emulator was running.

A NOx nitrogen oxide sensor is a device that is used to analyse the emissions of a vehicle and determine the amount of nitrogen oxides being produced.

It is typically placed before or after the catalyst in the SCR system to calculate if the emissions are at an appropriate level.

Euro 5 trucks usually have 1 NOx sensor. If a NOx sensor fails, the vehicle can have multiple faults on the dashboard which will cap the power of your truck Limp mode. As NOx sensors are directly linked to the SCR system, there will also be emission and general SCR system faults, which only add onto the list of issues.

Thankfully, fixing a NOx sensor is not that difficult, but can be expensive depending on the solution:. These are not all the solutions, but you can already see that the main concern for these solutions would be budget and reliability. We can always advise on the best solution for you — contact us to have a conversation with our friendly support staff.

What happens when the NOx sensor fails? Thankfully, fixing a NOx sensor is not that difficult, but can be expensive depending on the solution: Replacing the NOx sensor Around EUR will get you a new NOx sensor to replace the faulty one on your vehicle. While it is an ideal solution, you still run a risk of it happening in the future, meaning that there will be more money spent on repairs.

Purchasing a refurbished NOx sensor Refurbished NOx sensors are very commonly found in garages, services and part shops. They are cheaper than new NOx sensors around 1. In the end they do not solve the main issue of reliability as well. Usage and installation is quite simple — connect a few wires to the vehicle and you will have full imitation of the NOx sensor within your vehicle. Best thing? They are many times cheaper than NOx sensors and they can also be used with a faulty catalyst saving you a large amount of money otherwise spent on repairs.

Our CanSmart NOx emulators are offered with 2 years of warranty and a day refund guarantee, so you will not have to worry about the NOx sensor anymore.

Also, you need to connect the constant power supply to the module 30 terminal and disconnecting the power supply from the EAS-3 system and its components. If you are connecting the module in the truck cabin, you have to set the wires from A-CAN to the module connection place in the cabin. If you are connecting the AdBlue Emulator module to the EAS-3 connector, you have to remove only D26 E, 20A fuse and another fuse must stay in because this module requires a constant power supply.
