Odd slight stutter and smoke

[JagXDave]

Hi all, 

Got a slight issue with 55plate 56k 2litre diesel manual.

When driving steady in any gear it seems to have a slight stutter and I have noticed it is a bit smoky from the rear, looks like a darkish grey and heavy black when on the accelerator a bit hard.

I am used to an old L200 so pretty much just blanked the Egr straight away on it and never had issues, I don't really want to mess too much with the Jag as it was running lovely until yesterday.

I not had it long and plan a good service, Oil and filter, fuel filter and air filter and pollen filter, will have a look at cleaning Egr and intake manifold and while it is off change the glow plugs.

Does anyone have any advice or suggestions?

Hi, Dave

Give it a good service and see if that helps. Could simply be an issue of neglect. Good Oil change might fix things. If it doesn’t, however, we’ll have to investigate further 🕵🏻‍♂️

All the best

Thanks Marty, 

It was a one owner and did no more than 2k a year, he had it serviced religiously with jaguar but it has stood still under its cover for 6months, 

I've driven it for a couple weeks and I reckon it needs a good service,  fingers crossed it solves it, had a run of bad luck with cars and coud so with the x type being good for atleast 3years.

With such a low annual mileage for a Diesel I would be inclined to use an injector cleaner additive and then take it for a good long run at fairly high (but legal) speed.May be a build up of contamination caused by long standing period.

Sounds similar to mine, Dave. She was serviced religiously (at Jag) by the first guy, but it looks as though the second or third (I forget how many owners she’s had) didn’t do much with her. Looks as though the last owner maybe had her in storage, or just sitting outside, for a while too. He said he’d bought an XF, which leads me to believe the S Type just sat - maybe being used occasionally - to keep her running until he sold her. Seeing as the last service record is from a year ago, and because he didn’t seem like the DIY type, I believe she hasn’t been serviced - and probably not driven much - for a year. I dunno. What I do know is that there was a lot of cobwebs, dirt, leaves and other debris under the hood and in the filters. Brake discs and pads were filthy and corroded, coolant pipe was loose and leaking, filters filthy, Oil low and dirty. !Removed! me off when I saw the state of her under the hood and behind the wheels. 
 

Having said that, even though I’ve rejuvenated her, I still feel she’s sluggish. I’m praying she’s just still half asleep and bunged up from being neglected and in hibernation, and that there’s nothing seriously wrong. I’ve emptied a million bottles of additives into the tank lol, and will continue to do so periodically, in the hope they will clear her out. Admittedly, and shamefully, however, I haven’t used her as much as I should. Need to get her on a long run down the motorway. 
 

Hope everything goes well for you. Keep us updated. If you need any help (probably can’t offer much), just give me a shout. I’m in the North East, if you ever need a spare set of hands 👍🏻
 

All the best

Thanks Marty

Changed the air filter and fuel filter today.

Filled the new fuel filter with injection system cleaner, done it to all my diesels, works a treat, haven't done many miles since and noticed a bit of crud coming out, hopefully will clear and run cleaner, she does sound a bit smoother, going to do a full Oil flush and change with a new decent Oil filter.

I need this motor to last a good 3 years or more.

Fed up with changing cars each year.

I can’t see why she won’t last you 3 years, Dave. 
 

My girl is running better now too. I changed the fuel filter as well, but didn’t fill it with cleaner, as I didn’t know that was a thing until recently. She seems to be running pretty good, however, after the extensive service, Shell V-Power diesel, and many bottles of additives I’ve given her. 
 

You might want to clean or replace the MAP sensor — easy job and really helps. Can do the MAF as well, but I didn’t noticed much difference after cleaning mine. 
 

Keep us up to speed on her progress, Dave. I’m sure there are lots of knowledgeable folk on here who can help you if you run into problems. 
 

Take care

So after a few bits pulled and cleaned including Egr, few sensors and intake manifold, I found the top boost hose had a small split, replaced it and 50yards down the road the bottom split, changed that and all much much better.

[Marty1488]

Glad things are going well. Which one’s the boost hose? 
 

I recently blanked my EGR and never looked back. Luckily, I don’t have a DPF. Also replaced one of the injectors because I was getting a cylinder 1 fault code. Still have a coolant drain/leak or maybe I don’t after the recent drain/replace — haven’t had her out enough to tell. Coolant must’ve been ancient, however, because I couldn’t even remove the undertray due to corrosion of the screws, so had to cut through the plastic to get at it. 
 

she seems to be running a lot better now. Not sure if she’ll ever be like new, but I’m going to continue to try and get her close.
 

Keep me posted.

Can I Ask, 

When you blanked the Egr, did you use full blank or one with hole in it?,  did you get any Eml light?, Mines a 2 litre and I've had different reports, I am planning a remap and they will delete the Egr from Ecu.

I've always blanked my egr's in the past but they have been older cars and trucks.

[Marty1488]

Hi, Dave

Hope you’re keeping well (never sure whether to “quote” or just reply to the topic lol). 
 

I completely blanked it off at the throttle body and where the pipe meets the — cooler(?), and removed the two pipes completely. So, four plates in total for the S Type (X2004). Not sure if the X Type is the same. I got no light or anything, and I didn’t remove the throttle body butterfly, because I wasn’t sure how, even though others advise to do so. Not sure if this makes a difference or not. 
 

I did some research on my model and discovered that deleting the EGR from the ECU isn’t necessary. However, if the garage is going to sort all that out for you, then let them get on with it. Maybe they’ll discover it’s unnecessary. I dunno. I’d have to research the X Type to know. 
 

Not sure if it was related, but I got an “unusal flow” (or something like that) alert recently. I removed the throttle body, checked the butterfly actuator, tightened the blanking plates, refitted everything, and now everything is fine again. 
 

unrelated to the EGR, but as an aside, I recently replaced the glow plugs (bit of a nightmare job) and the last one snapped off. So now I have to figure out how to remove that. Oh, joy. Incidentally, it seemed that the ones on the left bank(?) - passenger side - were all seized and dirty. Not sure if this is a sign something is wrong. 
 

I’m still getting coolant loss, particularly when I ride her hard. Mechanic found nothing after pressure test, and I did a block test and got a negative result for gasket failure. I suspect the heater core needs to be removed. I also recently replaced the transmission fluid and filter and reset the TCM/TCU — doing that on your back is a bar-steward lol. 
 

keep me up to speed on everything, please, Dave. I’m interested to know how everything goes, and would like to help, if I can. 
 

All the breast

Marty 😉

Thanks for the reply Marty, Yeah I'm the same when it comes to quote or reply.

The Boost hose goes from the intercooler up to the egr valve, mines in 2 peices with the sensor in between, not sure about the S types, never seen under the bonnet of one.

I'll sort a blank out ands leave everything in its place, my mot bloke is a good guy and doesn't mind it being blocked off just has to be in place.

I have to do the glow plugs before winter, I'm going to soak them for a few days before and after a journey, I heard they can be a pain, 

I watched a video on you tube on how to use a kit for removing a broken one,

I have heard about the throttle body butterfly mod, haven't looked into the pro's and con's, I will do though.

Regarding your S Type, Have you found any water puddled or dripping?, I had a 4x4 once that randomly lost a little coolant on booting it, turns out I had a weep from the water pump.

I've just done a full clutch change on mine, next up is Oil and filter change then Air con recharge, after that tyres then full suspension and some bushes and lastly a wheel bearing.

After all that is done I'll book it for a remap.

[Marty1488]

I found - what I believed to be coolant - dripping from the Ac pipe, just in front of the transmission, and behind (I think) the power steering hose, that sort of region — at the back of the largest section of the belly pan. However, I took her out recently, for a very aggressive drive, and when I parked up, there was steam(?) billowing out from the left (viewed from driver’s seat) of the engine, no coolant in the expansion tank (lol), and a shi*load of colourless, slightly viscous, scentless liquid pi**ing out of the belly pan, in the region I described previously. I decided it was normal after reading that water is naturally released from the AC system. Seams to me the engine is maybe overheating for some reason. I checked the coolant temp after said drive, and it was only around 95 celsius. I dunno, Dave 🤷🏻‍♂️

That's a weird one, never encountered that before, 

Hope you manage to get to the bottom of it mate.

We’ll triumph, Dave lol. Keep me posted on how you get along with everything. The suspension job sounds like a big undertaking, and not one I would relish. Next for me is broken glow plug removal and then full service. I’m praying the heater core doesn’t need to come out. Speak soon, mate. All the best, and give me shout if you need anything. Take care.
