Good day all.
Some of you may have read my previous post on servicing, so I opted to take truck to main dealer in my area. It’s a scania R480… Long story short had the egr light and engine malfunction light come on so took it in got it diagnosed, they told me it was the fan… so they changed it and about a grand later said it was fixed, however same lights are on again, only happens when it’s warm really so took it back and now they are saying it’s either the wiring to the fan and the loom or the ecu… problem is why didn’t they say that the first time, and how do I even know my fan was faulty?
What’s your opinion? Has this happened to anyone and should I trust this dealer again?
Staff have been helpful in reception but that’s no good if trucks still bust! Is it a case of process of illumination in cases like this?

Sounds shockingly similar to an issue I had recently.
Was doing some deliveries up in the lakes; heavy load, engine working hard. Fan came on, suddenly amber emissions light pops up also with 'excess emissions, 50% power in 50 hrs (limp mode basically)
Dropped it into Scania: ‘pointing to the EGR sensor’.
Sensor replaced, light cleared.
Happy as larry for the next few weeks. Then the red light comes in ‘excess emissions, engine power 50%’.
And it was.
Dropped back into scania… ‘pointing to the ECU; but it could be the fan’.
So the conversation went like this:
What’s the problem with the ECU?
Well, it might have been spiked.
By what?
The Fan.
So what’s the plan?
Send the ECU off for repair.
Right…but won’t the fan spike it again?
Yeah, if that’s the fault.
So why don’t we test the fan first?
Because we need a ‘good one’ to test it with.
Well can you get one? Yeah, but we’d need to charge you for a new fan.
Right…so basically you want to repair the ECU, and hope for the best, and if it spikes again, repair the ECU again and then replace the fan? Or, charge me for a replacement fan to test if my fan is faulty?
Yeah.
Fix the ECU and replace the ■■■■■■■ fan.
