Just looking for some thoughts. My 2017 TD6 died, has 93K miles and has always run like a champ. No issues prior to this. My wife called me from the store (maybe a mile away) and said the car was running rough. Just did it on the way home and not to the store. When she got home, I turned it on and it felt like it was missing a cylinder. Turned it off and it through several codes (P0272 - Cylinder 4 Contribution/Balance; P06F9 - Glow Plug Control Module 2 system Voltage; P052F - Glow Plug Control Module 1 system voltage; P2610 EM/PCM Internal Engine Off Timer Performance). All power was working. Turned it over again, and everything went dead. No power at all to anything in the car.

Talked to 2 mechanics (one we've taken our Range Rover to for years). Consensus was it was something electrical. Towed to regular mechanic. So here's were it gets interesting. They went to jump the starter directly, and the starter was completely dead. Then they went to turn the motor over by hand and it was seized. $32K for a remanufactured motor.

BUT here's my question... why is the car completely dead? there is no power to anything; no lights, no dash readouts. nothing. I've changed the battery. Is there a scenario where the maybe the starter failed and is holding the motor from turning over via the fly wheel? Or maybe an electrical failure to that would lock the motor up? If the ECM/Control Module failed, what would happen? It seems to me if there was a failure like a drive chain or it through a rod or some other mechanical failure, that there would still be power to all of the other components. I did not have the mechanic do any additional troubleshooting as I just assumed it was a lost cause.

Before I part the thing out, I keep coming back to maybe it isn't a mechanical failure but an electrical failure.

Any thoughts/experience would be appreciated!!!

 

Sorry for what's happened.

What oil do you use? brand? type?

What is your oil change intervals? 5K 8K 16K ?

What is your fuel filter intervals? 5K 8K 16K ?


The electrical part is a real puzzle to me.

 

A friend of mine had a Td6 Range Rover and had a nearly identical situation as you. Engine was running like crap, there were some loud rattling sounds and it completely seized up. Later found out the crankshaft snapped, which is a common problem with these engines. In fact, when Ford put this engine in the F-150, it got a completely new forged crankshaft, and has been a lot better than the JLR spec.

Never understood why people rave about the Td6. I always thought that while they're smooth and efficient, they are little underpowered and they're notoriously unreliable, and never regretted having the supercharged V6 in my D5. Plus the supercharged has an increased towing capacity by 500 lbs.

 

Thanks Cincy!!! Interesting about the crankshaft. If I end up having to part it out, I will tear down the motor to see what happened.

 

5W-30, Castrol 10K Mile oil changed every 5-6K.

Fuel filter every 20K

the electrical issue is what keeps me from parting it out. Though I suspect it's mechanical.

 

That's a good maintenance routine. My 17 TDV6 is at 108K.

Thanks for the info!

 

Notoriously unreliable is a bit of a stretch. Mine's also been great now at 115k miles. We're going to have bias on these forums because people generally come with issues, less to post about how great their experiences have been. Having owned mine for five years and seeing the issues, most of them have to do with inherent modern diesel engine issues and aftertreatment DPF/scr/EGR. What makes it worse is people exercise drive cycles that OEMs specifically discourage for diesels. I'm a class 8 heavy truck engineer, it's no different in that market. Don't do a lot of idling or short trips else you're going to have emissions related problems. Snapped crankshafts are a thing, but still not the normal or expectation in my opinion.

 

Agreed with @RyanLR3. 125,500 miles on my '17 TD6 HSE and have only had 1 check engine light on mine related to 1 of the 2 coolant temperature sensors. Otherwise this vehicle has been rock solid and the most reliable car I've ever driven outside of our 2010 Volvo V70.
