Adblue Jaguar DEF issues

[DOK2]

Hi,

I had a message come on the dash that incorrect DEF (Adblue) was detected and the engine would not start in so many miles which happened. Had the car collected and taken to Jaguar as it is still under warrenty (only 14000 mile on the clock).

I was informed by Jaguar main dealer it had incorrect Adblue in the tank, they drained the tank and refilled. This was done without my approval as I was not informed the tank would need to be drained.

I had to pay for this and I was told it was not covered by the warranty. Please note that no other liquid was put into the car, only the correct specification Adblue.

Having contacted Halfords where I bought the Adblue I received their response below-

A recent issue has come to light which affects all Jaguar, Land Rover and Range Rover vehicles after being refilled with Halfords AdBlue. A warning message appears on the dashboard claiming 'Incorrect diesel exhaust fluid detected'. The handbook recommends visiting their local Jaguar or Land Rover dealership to be drained and replaced.

Our AdBlue complies with all ISO 22241 regulations including ISO 22241-1, which specifies what AdBlue is made of and the quality of the ingredients and ISO 22241-2, which specifies how the product is tested. We can categorically say that our AdBlue is perfectly safe to use in all JLR cars, and there is no need to drain the tank or any other remedial work.


The Jaguar handbook does not state that the Adblue must be purchased for Jaguar only or at all other than the specification which I followed.

The cost to me was £186 which I feel excess to say the least for what would be a quick repair if needed in the first place.

Has this happened to anyone on here as I think there is a bigger issue going on? I would be grateful if you could advise if you had this issue also.

I believe its a faulty NOX sensor and not the Adblue.

Thanks

Out of interest, which model is it and at what mileage did you need to top up? Mine went all the way to its 20k first service without requiring a top up and I drove it very hard (c.39mpg) so my adblue consumption will have been on the higher side.

Hi

Jag XF R Sport, 14000 miles and has been topped up 3 times so far.

Jag XF R Sport, 14000 miles and have had to fill the Adblue tank 3 times already. Its drinking the stuff and I think it was a faulty sensor or software issue but they charged me to replace the fluid. I dot believe it was a Adblue issue as I have used the same type since I bought the car with no issues.

Try pinging WhatCar's helpdesk, or whatever it's called these days. I'd expect they'd at least be able to get your money back, and maybe they'll be able to get to the bottom of the story.

Thanks

Halfords admit their AdBlue is causing faults to be thrown on all JLR vehicles in their reply, which I find extremely odd as a quick google shows lots of references to people using Halfords AdBlue in Jaguars with no issue.

It's not down to Halfords to determine whether the tank needs to be drained or not, so likewise I'm surprised to see them flatly denying that it was needed. I would expect any customer service person to be a lot more circumspect about issues of liability and what should/shouldn't be done with a car that they have no direct relationship with.

I'd show the email to Jaguar and see what they say.

Hi,

Halfords state they are aware of the issue with JLR and states that their Adblue is perfectly fine to be used in the JLR cars and recommended I take it up with JLR which I have done. Its either a JAG issue or Halfords so trying to get to the bottom of it out of principle.
Either don't by a JAG or don't buy Halfords Adblue-who knows!!

The last time I took my car to a Jaguar dealer they were more interested in serving coffee than in servicing my car.

In hindsight you could have taken your car to an indy and got the tank drained for 1/3 of the price... but either way your dealer should have got your consent to do the work before starting. That said, by then you had little choice but pay up

Yep, feeling scammed!!
