I would do, but its 45 miles away and just not practical to get there I'm afraid.
I've booked it in down the road for Friday, they are going to do a forced regen if the DPF isn't too clogged. Will take it from there.
I feel a petrol car coming soon...........

Cleared the codes last night, set off to work this morning. About 5 miles in limp mode kicked in. Drove down the M42 and M40 to Banbury in 4th fear, 3K revs. Reset the mpg reading to monitor the regen this way.
Was at 55mpg around the Warwick services, then fell to 52mpg quite quickly. After two mins the power came back. Rapid drive to work.
Left the CEL on to see what happens.
On the way back the limp mode came back. Was doing 80 in the outside lane, dropped back to the middle and kept between 60-70mph.
Stopped at a set of lights and the limp mode went, CEL still on. Another 5 miles of town driving and it is back.
On the drive, read the codes, still P1901 DPF related.

So, it did do a regen and it worked, but then quickly clogged back up again.
Maybe a sensor, maybe the manifold is clogged causing the soot to push through the exhaust.

I’m going to strip the EGR and TB down this evening, see if I can detect anything simple.

Interesting.
The TB and intake pipe had the usual oil film but nothing overly mucked up.
EGR looked ok at first inspection, the solenoid pin moves freely, but the actual valve was jammed, only a mm of play to open/close. Cleaned the spring and valve seats and whole unit, moving freely again.
Wondering it the sticking valve would cause the exhaust to over soot, combined with the duff cylinder number four swirl flap.
Checked the swirl actuator and all good.
Put the lot back together after a thorough clean.
Quick test drive and the CEL came back on. Same P1901 code.
Need to get the sub code to track down if it’s just a regen failure or a sensor or more.

I’m not letting this beat me.....

Seemingly sorted.....

After the EGR valve “fix” I added a bottle of Redex DPF cleaner to 2/3 of a tank. I’ve done Kettering and back and today Banbury and back the last two days.
CEL came on as I got on the M42 Monday morning, limp mode, but it cleared and returned to full power half way along the A14.
CEL still on during the return journey and again to Banbury. But still no limp mode....phew. Drove back this afternoon and still good, the CEL has turned off. Bonus.

So, the duff swirl flap issue combined with the jammed EGR must have been pushing too much soot through the DPF, the ECU wasn’t able to regen quick enough, hence all the lights and limp modes.
I’ve got my fingers crossed that this has been resolved now.

I did say I wasn’t giving up.

Driving down the M42 this morning, loud bang on the front windscreen, stone from a truck I think.
Does this look repairable to you?

It’s to the right of the rear view mirror, certainly in line of sight, so undoubtedly an MOT fail.

Look on YouTube for screen chip repairs.

I’ve had several stone chips repaired before, but not with the crack as I have in this one.

Thanks for the link.
Looks relatively simple to do, maybe worth a try. The kits are between £5 and £9 so not out of reach!
If the process works the same as the video, and the chip looks just the same, is still be concerned that it would be an MOT fail with the crack showing.
Will read some more and decide which way to go.

I suppose it depends on how strict the mot guy is.

A better repair.

Certainly giving me the thought to do it myself..... definitely worth a try.
What could go wrong really?

I've got a very similar one on my 9-5 windscreen, albeit on the passenger side - picked up from a lorry coming the other way on the Fosse. As you say, huge bang and your initial thought is what is that?! I was expecting it to spread but it hasn't.

If it's 145mm either side of the steering wheel centre then the limit is 10mm diameter for it to pass an MoT. Might be worth measuring before worrying too much about it...

Thanks for the info James.
It’s 80mm to the left of the steering wheel and is 13mm in diameter. @r5e.

Sorted the chip in the screen. Bought a Rainex kit for £7, spent an age reading and then re-reading the instructions before having a go.
Bit fiddly but seemed to work well. Transformed the chip, can only see a few tiny hair line cracks now, and only if you look really hard.

The car has been “fluttering” on initial start up for a few weeks now. 10 - 20 seconds and then the tick over is fine.
A stutter in the engine, almost like it’s about to stall.
Took the engine cover off this morning and the number four cylinder swirl flap brass bar had worked loose from the bar. The tiny Allen key has dropped off and was lying on the head. Hence be fluctuation in idle on start up, three cylinders were doing one thing and number four was doing it’s own thing.
Connected up again, a drop of loctite this time!
Started fine. Will need to keep an eye on it.

Another CEL this morning, P1901 code suggesting the DPF again. No issues with running or power for the journey today, got home and read/reset the code.

Did a visual check of the DPF sensor attached to the bulkhead, all wiring seems intact, no splits in the rubber pipe section.
Will see how it runs tomorrow.

While I had the torch out I noticed what looked like a spanner head poking out from under be gear linkage....wiggled it free and found a 10mm spanner! No idea how long that had been there, definitely not one of mine, so at least 2.5 years.
