XE 2.0d ad-blue issues?

[jmansion]

I'm advised by my son that he has a couple of friends that had issues with unreliability of XE 2.0d seemingly around the adblue systems. I'm considering purchasing an XE 2.0d.

Is this a known weak area?
How serious is it?
Is there a fix that a specialist might be able to provide?

Thanks
James

The AdBlue system is the least of your worries. Google "ingenium diesel" for more information. To summarise - the 2.0d ingenium engine was engineered down to a price and in a hurry because Jaguar were losing their supply deal with Ford for the Duratorque diesels and had to come up with their own. Reliability is sub-par as a result.

Read this, should help you decide.

My girlfriend has an XF with the same engine/emissions gubbins in it. Obviously the internet would have you believe the engine will explode long before the adblue system plays up, but my girlfriend's has (thusfar) stubbornly refused to expire!

When the car thinks the adblue system is not working correctly, you get a countdown of doom ... telling you how many miles you can drive before the car slaps you on the wrist for driving round without the emissions reduction malarkey fully working and will refuse to start again until a dealer tells it that everything is ticketty boo. The countdown starts at about 560 miles or so - so it's not going to leave you caught out unless it happens in the middle of a continental road trip!

Your choices are to either get the emissions system investigated, and whichever sensor or injector is playing up gets cleaned/replaced ... or you go see one of the numerous people offering to code out the adblue system warnings, and the car just carries on as normal. The first option is potentially expensive if you can't work on the car yourself, but you have the peace of mind of your car being fully legal, compliant and minimally polluting. The second option costs about £80, and while it is a breach of legislation to disable the emission reduction systems, it won't show up at the MOT and is pretty difficult to conclusively prove at the side of the road. Therefore the chances of actually getting caught for it are very low.

Your wallet and conscience will dictate which route you take when presented with that issue.

Of all the things that can go wrong with the 2L diesel, the emissions system is not the one to keep you awake at night. Between the turbo, the timing chain, and the potential for oil dilution (it's not designed for lots of short journeys, and needs a regular long run to allow a full DPF clean - this is done by dumping a load of diesel into the DPF and that cleaning it out. If the clean is interrupted, for example by it trying to clean during a short journey, then that excess diesel is dumped into the sump. If that happens too often, the engine oil is diluted by the diesel and you get metal grinding on metal in a very expensive fashion), the 2L diesel has pretty much every base covered as far as unreliability is concerned.

The DPF regen issue is far less of a problem on the XE compared to the E-Pace (and the RR Evoque) because it is on a shortened XF chassis with the engine placed longitudinally, rather than transversely leading to the positioning of the DPF being adversely compromise and not being close enough to the engine to generate the heat required to burn off the soot. This leads to repeated regens which cause the oil dilution.

However, the main issue is the very cheap, under engineered valve train with components that just aren't strong enough to remain reliable for what was supposed to be the lifetime of the engine. While this problem is compounded on the transverse engined cars because of the compromised lubrication (see above) it is still an issue for all cars especially if the standard oil change intervals are adhered to.

Thank you. I had heard that the 2L diesel was even worse in the transverse engine'd cars, but wasn't 100% sure on the why.

I still wouldn't want to be using a DPF equipped diesel predominantly on a short school run (for example), whichever way the engine sat!

Avoid this junk because there are better cars out there for the money .
