is this hose connected ok?

yes, they come with a code which equates to the tolerances of the injector (deviation). You enter that code in the VCDS then you run an adaptation on the engine where the car does it's own thing, revs up and down for a few minutes. You can ring the garage and ask. If the judder is because of an injector then it will get worse over time and will throw an error code indicating the issue. Don't spend anymore money until you know

personally, I don't think you need 1000miles to recalibrate anything, they have VCDS, they code the new injector which is essentially the deviation of the injector. They run an adaptation via VCDS where the car revs on it's on to establish the new injector values and you're good to go. Like I said to you, you will end up chasing this judder for ages, just drive it and if there's something broken then it will get worse eventually and it's about to show something. It's sht advice, but it's my best advice.

the egr on these might fail because of the actuator mechanism and also being clogged, You can't/shouldn't really try and fix it, just replace it if you managed to get it off. It will give you an error code if it was the issue. I think it's something to do with the fuelling system, injectors or pump or something like that. If we have the same problem.

I find that people are quick to blame this on the DMF. Mine had and still has the same issue since I bought it at 30k mile an now with 130k miles. Over the years I changed all mounts, the flywheel (mine didn't have a DMF) 4 injectors, a new EGR, DPF cleaned etc and it still does the same judder. My wife says there's nothing wrong, I say it judders for a few seconds when I accelerate or decelerate. Almost as if the engine wants to leave the engine bay. It's down to you to go through the process of elimination.

my 1.6tdi has 134k miles, I don't have a DMF just a solid flywheel. I have a judder too when under load and I think it's from my injectors. I spent £1000 on reconditioned injectors which are rubbish and now I live with it. If I go past 1500rpm it doesn't do it but anything below it starts juddering. I too in the past was chasing this judder, replaced all mounts and clutch + flywheel. When I put my foot down it feels like the engine is launching forward with a few 'bounces'. My wife says she doesn't notice anything wrong with the car I'm just OCD about everything. I drive it the way it is.

it's a well known fact that Mx-5s after a certain year don't have a real oil pressure reading. You can research it if you wish, I don't care that much to be honest, we have digresses from OPs post in typical forum fashion, my apologies.

of course not, I was referring to the original question. pre 1995 had real ones.

my 2007 roomster has a blanking plate where the oil level sensor is. I have a MX5 which indicates the oil pressure on the dash as you drive and even that one is not real, it's some sort of simulation driven by the revs. You need to fit one and code it with VCDS

thank you I did suspect that. Much obliged chaps.

Got a 1.6 petrol 130k miles from 2007. More generic questions more than roomster specific. Having issues with the battery is not holding much power especially since the weather turned. Power steering cut off and had to jump started this morning, considering I'm using it daily more than once. It's got an old Halfords battery, don't know the year but it looks old. I tested the alternator and it's registering 14.1 V at idle and lowest it went is about 13.6V when everything was switched on then climbed back to 14.1V Haynes manual states no more than 14v and no less than 12. Ideally between 12-13V. Is my alternator buggered? P.S. i have a brand new battery already waiting to be fitted but wanted to see if it's an alternator issue.

what type of AC module is it? what's written on it?

I do motorways only in my 1.6tdi. But I never look at the MPG dash as it keeps telling me I do these incredible figures. I use mpg calculator online to see what I've actually been doing.

funny reading my rant issue list from a while back. My latest cranckshaft bolt snapped a while back. Currently running it into the ground, not even fixing issues anymore.

that's 100 miles with reserve. Sounds about right?
