Absolutely correct, Dave. Started the car to drive home from the office - about 15 minutes in traffic and the light never came on once! Seemed to drive ok as well. A friend of mine is an engineer / technician with Allianz so I'll get him to run a diagnostic for me. Cheers - Allan

Hey everyone, got a brand new warning light today. Nice and refreshing to have something new to worry about!!! Anyway, Red traingle warning light with message Reduced (or Limited) Performance. Accompanied by noticable loss in power. Very slow to build up speed and would not rev more than 2500. No smoke / noise / smell or anything else just immediate loss of power for apparently no reason. I was taking the car on a run to ward off the dreaded amber DPF warning light (which is my way of dealing with it as I only usually drive short distances). Was in the middle of nowhere so had no choice but to keep going. In the office now without access to the manual so was hoping some of the good people on here could point me in the right direction.

Like many, given the current "lockdown" situation, over the past couple of weeks I have only been using my car ( 2013 XF 3.0D Portfolio) for local shopping trips. I use the car because I can get more shopping (stock permitting) and therefore reduce the number of times that I have to leave the flat, thus reduce exposure to any virus etc. Seems sensible, if we take the government advice and every thing else at face value. Now then, I know from previous experience (well documented in the XF forum) that before too long, these short trips are going to result in the DPF warning light appearing yet again. I know, also from previous experience that it is fairly easy and straightforward to clear an amber DPF warning light by taking the car on a run. So, would taking the car on a run to clear the DPF in such circumstances be considered "essential" or run the risk of a ticket if stopped by the police? The only other option would be to return directly to home and call the AA. Thereby using up scarce and valuable resources for something that is relatively trivial and easily dealt with and also it would mean that a third party (the AA technician) is at increased risk unnecessarily. MODS - if this needs to be in a different forum, please move/ Allan

Just to bring my input for this thread to a close. Spent ages searchng for local garages using Autologic. Found a couple but when I mentioned the specific problem it sounded like they didn't have a clue! Decided not to risk any more costly mistakes so bit the bullet and booked it into E+E for this morning. About an hour and half drive from Dagenham so could have been worse! Met a chap there who had driven down from Liverpool for exactly the same fix. As mentioned above, 15 minutes later I was on my way back home , £90 lighter but problem fixed. So much for getting a cheap battery! Still, lesson learned. Now to start looking for that BMW I fancy!

Hi everyone, was going to start a new thread but decided to piggy back on this as the issues I've just encountered are very similar. Was getting messages on start up about low battery and "system will shut down in 1 minte" (never did). Plus the air vents wouldn't open as normal on start up and the eco stop / start wouldn't work. No loss that last one as I can't stand it and usually switch it off whist driving. Anyhoo, decided to invest in a new battery. It's a 2013 XF 3.0 Portfolio that I've had since August 2017 so I figured if it was the original battery then it could do with changing anyway. Technician friend of mind changed the battery this morning. Obviously had to reset the clock etc and all seemed ok until I locked the car using the fob. The mirrors wouldn't fold as they previously did. Also, upon clicking the fob twice as I always have there was the usual beep upon the second click (which was when the mirrors used to automatically fold). But now, not only do the mirrors NOT automatically fold as before but after a few moments there was a further, louder double beep - something I have never heard before. Opened the car again and went through all the settings - all set back to as before the battery change (twice) - locked the car again with a doule click and exactly the same. Ended up, opening the car once again, folding the mirrors using the door buttons and then just double click locking the car up and leaving it. Reading through this thread I now presume that a recoding might be necessary??

Thanks, Peter. My technician friend will be changing my front brake pad sensor later today and has said he will check the diagnostics again. He's fairly certain it is the EGR valves, though. He also agrees that, although additives may / not help with DPF problems, no amount of additive will solve the valve issues. The annoying thing is that I selected an "approved" used Jag specifically for some peace of mind and I've had nothing but grief with it. This will definitely be the last jag I will ever own! Cheers, anyway - Allan

False Dawn?? As posted on 18 June (last Tuesday) I added some Millers diesel eco plus and the engine warning light disappeared instantly. On the Thursday (20th) I topped the tank up with diesel (about half a tank) and added another measured dose of Millers as I was driving to Bath early the following morning. Round trip to Bath (from Dagenham) plus some local driving probably put about 400 miles on the clock. I'd again topped the tank up (again, about half a tank) prior to the return journey but didn't have the Millers with me. Not a sign of the dreaded warning light, though. Hey ho, jumped into the car to drive home from the office yesterday afternoon and it's reared it's unwelcome head once again. Added another dose of Millers to the tank this morning but it wasn't to be. Amber engine warning light still there. I am at my wits end!

Well, now then. Either this is an amazing coincidence or that stuff is !Removed! good! Treated the motor to a shot of Millers this morning whilst I was waiting for my number plates to be fitted.On the way to Halfords, the amber engine warning light was on as it had been for the past few days. Millers ECO Plus Diesel added and as I was pulling out of Halfords.... no warning light. Gone. Surely, it can't have worked that quickly?? But.. never look a gift horse. I'm still rather skeptical but that is probably my suspicious nature. I'll take it as a plus and keep an eye on things but if it has worked then it is all down to the amazing advice on here and a million thanks to "old" Peter, Jon et al.

Ah, hence; "old" Peter. I meant no disrespect. Thanks for the replies, especially Jon and Peter. The Terraclean outlet where I made an enquiry haven't got back to me as yet, so, as I have a journey this weekend (round trip from Dagenham to Bath) I think I will give that Millers a try and keep a very close eye on the dash and see what happens. Off to Halfords in the morning for some Millers. I know they're not the cheapest place but I need to get some number plates made up as well so, hopefully my premium members' discount card will save me a couple of quid. Thanks guys!

Hi all, the problems I have had with the DPF (well documented in other threads) is now largely kept under control by using Shell V power and making sure I take the car for at least one long run per week. You can probably gather from the above that Jaguar themselves did absolutely diddly about it but I am resigned to living with the issues as best I can. Well, that was until the other day when I noticed I now have an amber engine warning light on as well. Handbook says it could be engine / transmission emissions related. A technician friend of mine hooked it up to computer and said it was showing EGR fault (think that's right). Reading through some other old threads on here and I noticed that "Old Peter" had mentioned something about a Terraclean he'd had done a while back. Quick recap, I have a 2013 XF 3.0 Diesel Portfolio (with less than 46500 on the odo). Does anybody have any previous experience / knowledge whether something like a Terraclean might actually help or heaven forbid, even make matters worse? As always, all comments and replies are gratefully received. Thanks - Allan

Many thanks Steve. You've covered all of the issues that were buzzing around my head whilst thinking about this. Will also try to find that other thread. Cheers!

Almost a year now since I bought my XF so have just booked it's first service (in my care). I'm expecting an eye watering bill so was just wondering what other members thought of the Jaguar Service Plan route?? Cheers - Allan

Well now, despite a round trip from Dagenham to Bath in excess of 300 plus local driving and switching to V Power premium grade diesel, that blasted light came on again this week. The good news is that H A fox are now talking to me again (amazing what the truth posted on social media will do), to be fair, they came up with a plausible excuse for the breakdown in communications. Upshot is that they have agreed to take the car in to investigate the DPF problem. Here's the kicker; they have said they will need the car for at least 3-4 days as investigating DPF issues can be quite problematic. I don't know whether to feel quietly confident that they are preparing for a thorough investigation or miffed that they are yanking my chain! Has anyone else ever been told such a task would require them keeping the car for such a time?? They have asked whether I would need a courtesy vehicle so may not have much choice!

Just as an aside and by way of light relief; I've been reading various tips and suggestions about trying to avoid or overcome the DPF problems. These include a different driving style, longer runs and even using the paddle shifts to make the engine work that little bit harder. It occurred to me that when I had my old X Type, I used to drive everywhere in sport mode. Having consulted the manual to find out how to select sports mode on the XF (yeah, I know, what a newbie)! - I decided to give that a go. Now, I know it's less economical and far too early to say whether it might help with the DPF issue but I will say one thing - Jeeeeez - what a weapon!!! Phew!!

Hi Peter, thanks for that. Would you (or anyone else) happen to know the position on using an additive in respect of the Jaguar approved warranty. I'm happy to try anything, including the use of an additive but don't want to find out later that it invalidates any warranty cover I might have. Cheers.
