I was also told dealers for some brands are now charging $180-$190 per HR for labour... That cannot be correct can it?

No mistype,see my post above.

LR charged me $220/hr in 2012,i hate to think what they charge now.

The local Tojo dealer charges us $160 Hr,which i dont think is too bad,probably something similar to an LR Indie.
Synthetic Castrol DPF engine oil,5W/30 from the local Tojo dealer is cheaper today, than LR charged me for the cheaper non DPF Castrol 5w/30 oil,in 2012.

After those efforts from LR,i didnt go back,except for warranty issues,and there were a few of them.I only had the D4 serviced by them once,because it was in getting warranty work done.

Forgot to mention that as it does confuse some

Back in my box!

There you go, is that to burn out the DPF?

There is always something to learn

Yes,inject fuel, heat it up to burn off.

What happens with these is the injectors get corrosion on them.
Then they overfuel and clog up the DPF's,which then have to be replaced.
The other parts are replaced,different from original, so it doesnt happen again,EGR,coolers,etc,also software upgrade.
I dont know exactly why it happens,some say something to do with moisture when the engine cools off,maybe condensation?

One thing i do know is they downloaded info from the ECU and sent it to the manufacturer before the repairs were authorised.
The ECU records a lot of info about how the vehicle is driven,etc.
If the vehicle had been modded or tuned,they would not have covered the repair.

Thats a really interesting system in doing all of that. I hadnt heard of it. I don't think my Audi does that when it has a DPF burn off.

Thanks!

My brother has a 2013 Mazda 6 diesel - he bought it a couple of years ago with 50,000km and it now has 210,000km. Not sure of the exact details but these engines pump raw fuel into the DPF to burn of the carbon etc but the engine has a design fault and the fuel can sometimes find its way into the sump - the car has a sensor to pick this up. Anyway the car was being driven to work and the engine failed due to poor lubrication caused by fuel dilution of the oil - the sensor had failed.

Car is now in with Mazda getting a new engine $10K-$15K - no cost to my brother - as I said this is on a car with 210,000km and was bought as a second hand vehicle.

A pity LR did not have the same customer service ethic.

While LR don't seem to have the same customer service ethic, some of their engines do have the same sort of fault....Early Service/Oil Dilution - JLRP00100 | Evoque Owners Club

I believe if the oil dilution problem goes unnoticed it leads to premature camshaft wear.

Yep, diesel doesn't do that good a job in an oil sump

Was speaking with Ryan from Turbo Technics UK recently (produce remanufactured turbos for JLR, among other things) on another matter who was saying they were almost out of core for the ingenium engines due to ridiculous amounts of fuel dilution failures.

Many European vehicles use a different system,but can lead to oil dilution.

I cant remember exactly how it works,google wil probably help

So the simpler version is to simply pump fuel in late in the cycle so it flows out in the exhaust stroke, flooding the exhaust, increasing exhaust temp and the burn off. This is much like what anti-lag did on turbo cars - pump fuel late in the cycle when you come off throttle and that fuel ignites into the exhaust spooling the turbo and making wonder pop pop sounds.

As you suggest though, this excess fuel that is designed to assist the burn off for the DPF also runs back into the cylinder and then past the rings into the oil. Now we have the issues of fuel dilution.

Toyota’s idea avoids that by providing fuel where needed, but clearly didn’t anticipate the variances of the exhaust environment.
