Now there’s something wrong with this photo of a DAF XF 2016 engine ECU, just can’t figure it out, truck doesn’t start & throws an open circuit fault for the electronic common rail release valve….hmm

P.S. vehicle starts & drives fine with a brand new one on 🛠

Loving the DAF DPF puller tool, every special tool has its price, but to make the job far easier, boost your confidence & complete said job with perfection…price shouldn’t matter 👍

The mid 2017> DAF CF & XF exhaust boxes house the DPF in the same place as the older Euro 6’s, but these DPFs seem to be a lot tighter to fit, given the compact size of the exhaust box as well.

Simply turn the wheel full lock to the left, remove the covers & clamp, & crack on. Here you can see the element has shifted without even measuring the depth. DOC seems to be hit with a fair bit of soot, but it’s expected as the DPF inlet face is quite close to the DOC.

A nice clean housing before a part change as well. 💪

Near the end of the year we tackled a Renault DTI11 tractor unit with a power issue, terrible pulling with a load on its back especially.

Diagnostics on & a fault for #2 pumping injector failure instantly got us thinking….it’s a Volvo engine, a pumping injector failure, do we have camshaft troubles?

After consoling many of our Volvo Tech friends for advice, we diagnosed the following:

-3x pumping unit injectors (Cyl #2, #4, #6)
-1x Exhaust rocker complete
-1x Solid camshaft (hollow from factory) kit

The steel injector sleeves were a pain to remove, a doddle to do with whole job itself, but we learned that all of this happens, due to the pumping injectors failing & seizing internally.

Funny how the trucks get hollow camshafts and the buses/coaches get solid camshafts apparently 🤯🥲

Typical DAF CF/XF 2018> (small exhaust box) with multiple warnings, some noticeable faults mentioned the DPF high pressure AFTER the DPF, most of the pressure should obviously be before the DPF as the soot hits the DOC first then the DPF inlet.

Quick check to make sure everything looks sound, we have a fuel stain and clear evidence that the element has shifted forward….less than 85mm from element to end casing 😔

This could be a SCR blockage kind of job too, but for now, parts parts parts!

Yet another DAF with a failed engine ECU, diagnosed over the phone came next day to program and we’re away!

The DAF CF/XF MX11 & MX13 engines are equipped with this ECU, they still fail for the same reason (along with other faults on the 2017> trucks) all the way from first production in 2014.

Fortunately for us we have the Davie 4 (Euro 6 diagnostic tool) and it is not a problem programming even the freshest truck on the road.

Being mobile has its benefits for our customers, no 3week wait for the dealer to make their mind up & certainly not their prices either.

DAF LF, high soot level, wouldn’t regen, eventually found a leaking/faulty EGR valve, checked the entire EGR system, fully coated in soot & moisture creating the sludge of death.

Final steps in putting it back together after a big clean out & parts replacement, the coolant pipe onto the EGR cooler went “drip”…”drip”…”drip” 🥺

Followed by plastic compressor coolant pipes breaking upon breathing near them, nothing is built to last anymore 😔

Keep forgetting to take a simple picture of the even simpler work carried out for the DAF CF/XF MY17 coolant level warning that’s setting many owner/operators back by thousands. This is a bulletin from DAF to dealers or agents alike for a certain batch of chassis numbers with the MX13 engine fitted.

The bulletin basically explains about an unnoticeable coolant loss & other excuses from DAF. The low coolant level warning is still amber but the warning sound stays on constantly instead of usually lullaby we all hear that stops after a few seconds.

To rectify this, a Davie 4 diagnostic tool has to reprogram the VIC-3 ECU, the warning goes off & you
carry on as normal. This reprogram function only resets it, it doesn’t remove it fully. We have been up and down the country with our little bypass method, armed with a Davie 4 just in case the warning has appeared.

Some customers have had this repair work of ours carried out prior to the coolant level warning. Below are the chassis numbers affected:

0G274270 - 0G298272
KG277776 - KG297719
LG285162 - LG297571

Give us a call if this issue has affected you, and/or you’re sick of the return trip to the dealer/agent.

Nice little engine swap along with a full exhaust for a DAF LF Euro 6. Obviously using all the best bits from both engines, giving the donor engine a proper EGR/inlet clean out unlike what most folk do, this Tunap 925 stuff is brilliant 💪

Vehicle had a multitude of engine/emissions faults, upon looking into it, we saw oil dribbles on the downpipe clamp & at the tail pipe stack….yes a turbo failure was the cause. With these EGR/Exhaust systems, it was either a full clean & refurb job, or straight swap.

When having emissions faults on DAF LFs, it’s not always NOX sensor or DPF related or issues like this, a lot of the time the inlet pressure sensor (before the turbo) fails & brings these warnings up, also with the common “SCR failure”, “AdBlue Dosing internal failure” and so on, usually codes ending in ‘-31’.

We find these problems with PTO fitted vehicles like skip wagons or even the scaffolding trucks. Feel free to call if you’re concerned about your trucks performance or general health.

As always, no time for pictures & stories! Just a fair few jobs as we’re leaning towards the dreaded winter for electrical work on trucks.

*Plenty of AdBlue/EGR/DPF work as per
*Multiple installations with the Brigade camera/radar sensor kits for our main customer in Pen*stone
*Couple of Scania air con pump diagnosis
*BPV actuator on a DAF
*Chinesium Volvo AdBlue pumps
*Coordinator malfunctions for Scanias
*Extra work lights & suzie prep work for some special Volvo Unlimited Edition FH’s
*Rear air suspension faults
*Trailer re-wire
*Truck EBS issues on DAF LF’s (as always)
*Some truck export software work
*Fuel issues on the DAF MX13 engines
*Side marker re wiring on our tipper customers (joyful as ever)
*Engine management faults hours before MOT, thankfully wiring
*Plus the driving all over the place to sort our customers out 👌💪

Aaaaaand so on!
