Dmax issues where do I stand?

[mendiplogs]

Seeing the vehicle is so new then it would be unfair of them on that mileage to put it right

 

As TCD said i bought one of the last Td5's in March and I had three months warranty and I had the oil level rise to a serious level spoke to the garage in Exeter and they took it in and they where told it was a crack in the cylinder head near one of the injector seats but they dismissed this and went there own way and said it was the injector tips and they where leaking diesel so they put new injectors in , I collected the Land Rover 10 days ago set the trip too zero and done some local driving nothing much stop start then did a day of trailer work came back in the dark on Monday checked the oil next morning and oil level very high again drained the engine again and out came 10.5 litres of runny diesel oil and I had only done 343 miles so a telephone call and a letter from a good independent Land Rover specialist and it's going in this week and have the head changed they said its cost us £1400 already but I said I've got a vehicle that's not fit for its intent and purposes

So beau stick with it and get them to sort it

Cheers

 

Hi Andrew what's £3)4K for large garage Andrew but to me and you it not good I had a new XS 90 like yours new on last TD5 only had it 5)6weeks sold as the gear got very hot thanks Jon

The DPF is removed and bypassed. I dont think its an option on such a new vehicle but if it was a few years down the road I would tear it off and fit the gizmo.

Removal is the best solution, the problem is the ECU has the be changed to block the DPF.

 

If you ever have an issue with the car and it goes back to VW or they service it they reset the ECU for updates etc.

 

Easy enough if you live 5 mins from the person that mapped it. However

some cars wont even drive with factory settings once its done.

 

I looked at having mine done (one guy is getting a comfortable 220bhp out of a 2.0 twin turbo). For me the issues outweighed benefits. Also, I'm pretty sure you would lose the warranty if they found out.

 

Once the car is out of warranty it will be a brilliant idea.

Hi all. Got a continuing problem with a rising oil level. Had it go from normal level to halfway to max in just 1200 miles. Got it booked in for a full check over but pretty sure there are no fixes available. Believe it's to do with the DPF and short trips gets diesel into the oil but that's my work so can't fix that. It's only a year old and still has 4 years of warranty left. Had planned to keep it for many years but can't imagine diesel in the oil is going to the engine much good in the long term so wondering what to do and what to expect from the dealer.

 

What is reasonable to expect from the dealer and do all trucks hate doing short trips and dump diesel in the oil?

 

 

Thanks

My mate had this problem. Had to have a new engine. Dealer/Isuzu paid.

Did the diesel in the oil kill the engine or have they developed a new engine without this problem?

keep us posted how you get on, iv had mine 2yrs & no issuse

D'oh forgot about the extra injection for burnoff !!

 

 

Before reading about dmax problems here I had not realised DPF regeneration was done this way, according to the article posted in the thread they have used the ability of a common rail system to squirt a bit of fuel during the exhaust stroke to reheat the exhaust and get the particle filter hot enough to burn off soot.

 

I had always assumed (from having removed one) that particle filters were a fine matrix of ceramic coated with a catalyst. The catalyst is there to lower the temperature necessary to burn the soot. As I have said elsewhere these small bits of carbon are actually quite difficult to burn and you only have milliseconds while the exhaust passes through the filter

 

Anyway the article suggests that the biodiesel fraction hits the cylinder walls and runs down into the sump oil because of its lower volatility.

 

It suggests the particle filter regenerates at 600C Apart from my thinking the exhaust gas temperature of a naturally aspirated diesel shouldn't get above 550C and a turbocharged one will be lower because useful work is done in expanding the gas through the turbine why not just have another injector in the manifold to regenerate the filter?

 

With the ford ids software you can query most of the sensors so if other engine management software is similar the delta pressure across the filter should be readable to give warning and maybe regenerate the filter off the vehicle??

 

Whilst I'm fairly sanguine about NOx from diesels in our climate I do consider PM 10s and 2.5 a health risk because of the chemicals in them, even though I drive a diesel van which has no particulate filter, at least its delivered between 60 and 70 mpg for the last 287k miles.

 

 

A bit of a ramble because I haven't though much about engines since I made my mother's imp difficult to drive by filing the head down with a surform.

That's exactly what GM are doing on their latest Duramax LML diesels in the US.

I'm not sure, only that he had diesel in the oil. I know that he had it serviced and not by an approved dealer and the problem started then.
