Re: Ad Blue Incorrect Quality and 512 mile Warning

Hi thought I would share my current DEF warning fun. I have recently had the dosing error message (different to the insufficient quality one). So - I took the car to the specialist (Paul at Ultimate Cats - total legend) and machine plugged in, error codes received and Jag contacted. I parked up the car, used the back up for work and drove precious miles watching the countdown at the weekend to keep the battery charged. Car is booked for Thursday to go in and get fiddled with. The weird thing is, today I drove out for a bit and THE MESSAGE DISAPPEARED!! Wtf?! I had been driving fairly constantly 400 miles per week throughout (key worker) before it appeared. From the messages here I guess I have urea crystals blocking up the injector but it appears to have resolved “naturally.” I will still take it in and ask the specialist to eyeball the various gubbins but if anyone has had the same experience or can advise I’d be grateful. I love my XE otherwise. The next one will definitely not be a diesel, though...

If the DEF tank was overfilled, who filled it and why?
Thanks for reply.

To give some context I bought the car in October last year and have drove roughly 3.5k miles. As I said before when I got the "Incorrect DEF quality detected" message I hadn't got any prompts or warnings regarding DEF before. I hadn't even thought about Adblue at all - this was my first ever warning message on the car. After getting this message and the countdown came on I decided, having consulted this forum to put 5 litres into the Adblue tank - to see if this would help remedy the warning as it could take some time to register etc. Considering the tank is meant to have a 16L capacity; in my opinion this could not have 'overfilled' the tank.

Would I have grounds for complaints?

Unfortunately I think you have shot yourself in the foot. If you can't check the DEF level your car is 1000 miles per litre so probably early 16. The later 500 miles per litre cars have a dashboard check for DEF. The warning that came up was about DEF quality, almost certainly wrong as it's never a quality problem anyway, it's always something else in DEF dosing chain. However it didn't tell you it needed refilling and when you added 5 litres you probably either got very near or over the tank capacity, at which point the sensor in the tank detected an overfill and probably triggered another fault. When you took it to the dealer he read the fault codes and found it overfilled so providing a justification for charging you a hefty sum for sorting it.

You could try a complaint and explain exactly what you did and why but I fear it will be a case of "Sorry Sir......."
This Adblue thing is a mystry to most of us. It is simply a mind game and everyone is guessing where is the 'max threshold'. I had two problems with the AbBlue sensors before and they were all dealt with by Jag under warrantly. The AbBlue tank was drained and filled in by Jag in March just before the warranty expired.

Accordingly to the above, I do not have a DEF level display and my reg is 17, hence it would fall within the 1000 miles per litre catergory. But why when I checked the count down clock when it was filled in March (I have done 100 miles max since March), it is showing me 5,000 miles, not 16,000 miles?

I think I may have misled you be saying you could check the DEF level. It’s not a level check, it just shows you how many miles you have left before a refill is required. This changed in 2016 when Jaguar did a model upgrade. One of the things they did was to add the round central display between the speedo and the rev counter. At the same time they doubled the adblue dose to the exhaust so that instead of 1000 mpl it became 500 mpl. They also made it possible to check the distance you had left before a refill was required. On the previous model 2015-2016 there was no way of checking and you had to either top it up as you went based on your mileage or just wait until the warning came up which was my preferred method, just adding 10 litres so I knew I was never overfilling the tank thereby causing further problems.
If you have a 17 car you have a round display and the dose is 500 mpl hence it shows a lower reading. Maybe it only had 10 litres added which would explain why it is now showing 5000 miles.

From now on I will make mine into a dealer to be topped up. For me, the £30 is worth it and it's not like it has to be filled every month. Last fill lasted over 9000 from memory.

Anyway, my lovely cat is going back on Thursday (lease). 5 lovely year's, almost trouble-free as well. Staying with jaguar and purchased a 2016 XF V6 diesel

What a lovely retirement present. Not. Been to the dealer twice for regeneration and then NOx sensor replacement. 46200 miles on the clock, totally cherished with full Jaguar main dealer FSH. Then this. Gutted. What next I don't know but I think I'm done with JLR.
