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.
