'Speed up!' sick Jag's owner told

2011-11-04 12:33

A Jaguar XF driver was reportedly told his luxury sedan was continually breaking down because he wasn’t driving fast enough.

The London Daily Mail reports owner Jonathan Dines was told his “inappropriate” driving style was to blame for his repair bills.

Dines bought the 18-month-old 3.0-litre diesel XF in November, 2010, and since then has seen his car grind to a halt on three occasions and witnessed the diesel particulate filter warning light turno on 15 times. The car was also booked in to the repair shop for a week and regularly switched to “limp mode” when Dines was driving at speeds under 50km/h.

But Jaguar in the UK has placed the blame squarely at Dines’ feet, saying the DPF becomes clogged if the car doesn’t get sufficient fast runs.

Dines said he works as an estate agent and most of his journeys are short.


“I was never told I had to drive in any particular way,” Dines told the Daily Mail.

“They’ve told me that the problem is that I’m driving too many short journeys and driving too slowly. I’ve driven a diesel before and the salesman knew I was an estate agent doing local, short journeys.

“You buy a prestige car and you expect to be able to drive it at whatever speed you want. You don’t imagine that a quality car would suffer from you going too slowly. I dreamed of owning a Jag but it’s not been a great experience.”

His local dealer conducted tests on the DPF and sent the data to Jaguar for further analysis.


Jaguar’s response was: “Looking at the average speed for both trip computers and the DTC’s stored in the vehicle, this is a driving style issue and will be chargeable to the owner.

“Please educate the customer on the driving cycles required to clean the filter reference the owner’s handbook.”

Dines was also warned any further failures won’t be covered by the car’s three-year warranty and feels the dealers have tried to wash their hands of him.

He is now considering legal action unless he gets a replacement car.


Regarding a similar situation applying to South African drivers, Jaguar South Africa had this to say.

"The issues with DPF are affecting not just Jaguar but many different brands, including Mercedes, BMW and Audi.

"The problem tends to stem from people with short commutes never reaching the required speed to allow the DPF system to regenerate. The DPF requires that the vehicle is driven at a steady speed (typically above 50mph/80km/h) to allow enough heat to be built up within the exhaust system to allow it to regenerate - this speed has to be maintained for several minutes for this to occur.

"The car will warn the driver that the system requires regeneration before it actually fails - unfortunately this is often ignored.

"There is no single, straightforward solution to this. The most obvious being better communication between the manufacturer and the end user on how the system operates and how to react should a warning light illuminate."

    You drive a jag - expect cr*p. An English car with Tata owners, nothing more needs to be said.

      Does it mean you must also expect cr*p from RangeRover as it's also owned by Tata?

    Stop driving your Jag like a Corolla and drive it properly.

    There's a great article about this in SA Car Magazine about this. (Appologies for having to mention a competative publication, I'm not a journalist just a petrol erm dieselhead) Many people tend to forget that most/all of fuel management systems are made by OEM manufacturer Bosch! The requirement of DPF is directly installed to comply with EU5 fuel compliancy. Thus any vehicle with this WILL have a DPF fitted. And yes DPF's seems to be problematic with short driving trips. Thus a diesel engined vehicle, with EU5 DPFs, should not be considered if you are going to use the vehicle as a 'moms taxi' or a 'jalopy' doing only short trips.

    This is a general problem with new "clean" diesels. I sell cars with DPF's and they have to be driven hard for at least 15 minutes every week in order to keep the filter clean. It has nothing to do with Jag or Tata or anything else. If you own a diesel with a closed DPF, you are going to have to drive it this way or it will give you problems!

    This adds to the reasons I still don't trust diesel engines despite improvements that have made to this technology. Will stick with trusty old expensive petrol for now.

      Eddy - 2011-11-08 13:30

      Not to mention the fun and great sound of petrol engines, unless one drives one of these econoboxes!

    i owned an E46 BMW 320d. Drove it like i stole and never had issues with any filters - the turbo seals however did give in at 169 000km's

  • Ian - 2011-11-30 12:38

    I drive a Fiat Multipla diesel and at 180 000 kms have had no problems with the diesel particulate filter at all. I do a mix of in town and semi rral driving.
