I hate cars...

Got 1.3g/s MAF with engine off. Is that an acceptable zero error? 100 Kpa atmospheric 101Kpa intake all off.
It's booked in on thursday....they also seem to think the dpf is suspect. If the burner needs replacing with a genuine Ford item looking >£K1. They also say they can clean the unit if possible.

What is the differential pressure sensor offset value? should be <0.008kPa with engine off, if it's over that or fluctuating then a defective or contaminated sensor is likely. MAF should be closer to zero but be aware that as it's a hot film sensor, the longer it's active with the engine not running, the greater the value (both airflow & IAT) If it turns out to be a defective fuel vapouriser, then it is possible to 'tell' the engine management that the DPF has been replaced when it hasn't, then run a forced regen. to enable an accurate soot & ash level to be calculated. They should know this but are most likely playing it by the book as a forced regen. on a potentially seriously overloaded DPF isn't risk-free.

My unit doesn't read that. Tomorrow at garage should reveal cause. Laptop k'boards got fizzy drink in it. Using onscreen k'board very slowly.

I hate cars too, I will qualify this rant too, with a new clutch for the car I bought last week. Yes, that said crying / ranting sound is me you can here, bloody cars, well, it was cheap.

To the OP @Hopefuldave and @Barking Mat

Nobody hates cars more than I do. Trust me on this one!

I've sorted my clutch issues for the moment, wasn't expensive.

Works a treat, I prefer to think the cables old and stretched, than the clutch is dying, might get me another 10k kms, hopefully.

Simple, only use the clutch to start from a stop.

I've never understood that clutchless gear change method, I know get the right revs, but its never worked for me, I've tried a few times to no avail.

I rode along with an old timer in his Mack Tri-axle dump truck, he showed me.
I then learned on my dodge 2500 with the 5/9 gas engine.
I don't have any stick vehicles anymore, and I've always felt the small cars and such
would not drive well sans clutch.
First lesson, don't force the stick, 2 finger grip only, float them in.
If you normally double clutch, your already half there.

Or if you're desperate, you don't need a clutch, I've nursed a car home a few miles by starting it in gear, up and down the box matching engine revs and knock it into neutral if you have to stop.

It is a matter of holding the gear lever gently against the gate whilst changing engine speed. At the sweet spot, it will just slick in.

I've done this on several occasions now, best one was on Swainswick hill going down in traffic and the clutch decided enough was enough. I was on my way to South Devon for a weeks holiday, managed to get it to the caravan we were stopping in and then to a local garage in the next town over. It was a bank holiday weekend, didn't get the car back till the penultimate day of the holiday!

Had it happen to my van in Andover on a farm job. I live near Rugby in Warwickshire. Made it back in one piece was an interesting trip back!

Very handy thing to be able to do!!

What fun it was to do the Mondeo clutch master cylinder! Must have been an 18" extension through a square hole in the dash, to get at one poxy fixing!

AND you have to remove the clocks and steering column!

Well professionals came up with same results.... a turbo warning 1550km prior and nothing recent.
Did offer a possible fix related to a solenoid at £400 with no gurantees. I declined and am now once more in the dark and £80 lighter. Not sure if the tech said he couldn't read DPF diff...wish I'd paid a bit more attention.

Latest with OBD is that another garage read it, whilst still in Devon, with obviously a better bit of kit, and found log was full of Battery management error codes, due to the many flat battery events. He cleard them all except one and suggested the possibilty that it might have caused the spurious event (no DTC)
Friday. I tested battery ambient drain and found it at 300mA! That's a good hr later, bonnet switch and door in dummy run.
So something at the rear of the car is causing battery drain which in turn is causing spurios DTC. That's the theory.
Now local garage is investigating after it passed it's MOT.
Find out today....although their diagnostic skill are uncharted.
Nope they didn't resolve it.

Easy enough with mechanical linkages, difficult with cable linkages.

I had a parasitic draw on a Dodge 2500, it ended up being the trailer connector, water & salt got in (like that would never happen eh ?).

Works well on some cars not so much on others

300mA is roughly 250mA too much, its around 3W so it may be worth checking the boot light isn't staying on...
After that, its good old detective work.

I heard < 25mA is about mark. Fuse pulling found usb on the c-max.....but later steering rack fault......RIP

 

[Ubique]

Most vehicles are in the 20-40mA quicient current range after some period of time, its very manufacturer and model (and model year) dependent but if you, in rough numbers, work on anything over 50mA is too much, then you should be OK.

Disconnected the towbar electrics at bonnet ......just a 6mm crimp eyelet. No obvious interior lights on either.
