Rear Badge

[JagmanXJR03]

Hello all. After swapping my 2003 s type petrol for a 2007 Diesel, I noticed there is no 2.7D badge on the rear. Even after trawling the net for pictures I am unsure whether it had been removed by the previous owner, or they were never put on from factory. Has anyone any ideas if I should put one on not?

From memory my previous S type diesel did not have one either.

Hello Andy. Thanks for the reply. I am still unsure if it would look any good, some Jaguar brochures have some in but it looks bad with the exhausts that are 'turned down'.

The 2.7 diesel did not have the badge and the models that have the exhaust tail pipes pointing down have not got the dreaded DPF filter.
If you only do short journey work keep your eye on the engine oil level if it starts to increase change it. Also I would give it a 20 mile run up and down the motorway once a week to clear the DPF filter.

Ahh. I wondered why they faced down. Your are right regarding the DPF filter, the light has already appeared a few times, but it gives me an excuse to go on a long drive to burn it off. Even on a long run, we struggle to get over 35mpg. We just had the 11th service (car completed 130k, and has FJSH and one previous owner who was meticulous with the car) do you check the oil every month, and would the oil level actually increase?

I would check the oil level every day, I know that sounds a bit extreme but you can't be to careful. The reason why the oil level rises is because when the DPF needs to regenerate extra fuel is introduced to basically catch fire in the filter and burn off any particulates that are blocking the system. If this fuel is not ignited it somehow feeds back into the lubrication system mixes with the oil diluting it and increasing the level in the sump. So to much oil and not of the right viscosity is obviously a recipe for disaster. This explanation might seem somewhat vague but it only what I have read on the subject on this and other forums. I to have a diesel model but it hasn't got the DPF filter.

Any rise in sump oil level needs immediate attention. As Jeff says, this is usually down the excessive fuel wash caused when the DPF burn out cycle is innitiated and the owner fails to let it run fully cycle due to the car being used on short journeys.

An oil level rise is a highly dangerous situation. At extreme, it can lead to the engine consuming its own oil due to the high level. This can lead to a diesel runaway situation. This can cause the engine not to be able to be switched off with it running uncontrollably to full throttle...it is usually necessary to call the fire brigade. See You tube videos on cars that have the condition....clouds of smoke, fire and eventual burn out.

Best advice is to suck or drop out the oil and replace with new at the correct level. Then take to a qualified person to have the DPF system looked at.

No diesel engine should be run on diluted engine oil. To do so routinely causes terminal crank bearing failure. It is imperitive that diesel owners monitor their oil levels to ensure they do not increase.

It is well known that these cars are best suited to long journeys in great preference to short journey use. Short journey use cars should have their oil changed more frequently to combat the effects of diesel fuel wash. In that respect, a small petrol car for regular domestic fetching and carrying makes a much better proposition, reserving the Jaguar 2.7 unit for long trips.
