Hmm...

So if it hasn't been mapped out and the plate probably isn't fitted, I'm assuming if I buy a plate it'll most likely chuck an eml on??

I'll buy the newer clamp and start pulling bits apart soon.

I might even buy a can of the spray cleaner to chuck in the turbo?!?

Don’t chuck anything into the turbo

If you send a pic of the egr valve I can tell if it has a plate fitted

On this model you don’t need it mapped out as a plate works fine without any management lights

It the plate isn’t fitted likelihood the value needs cleaning

Since the orange seal replacement have you reset codes and see what if it comes back

I have cleared them, but I'm now getting different codes.

I believe p1351 is a ghost code, the other 2 are new, one I believe is air dosser, the other egr?

I've read that the plate will put an eml on with the 1.6hdi?

I've seen a fair few people spraying egr cleaner into the inlet, I've done it before on my old 1.4hdi with good results.

P1351 is glow plugs I’d just forget that

P0122 seems to be egr butterfly issues

The other code seems to say about the throttle position sensor or throttle pedal possible wiring. I have replaced the

I did replace the throttle body years ago as it split and was leaking. Might be worth checking pipes and unplugging and reconnecting the connectors it in the left as you open the bonnet on the top

A plate won’t throw the light on this model done a few I haven’t mapped some of them out since the engine came out in 2004

I'll wait for the new clamp to arrive before I start pulling it apart.

From what I'm reading online, I think it's either the egr or dosser?

The doser is mainly there for dpf regens

You can test if it’s working ok by taking it off leaving it plugged in and getting someone to turn the ignition on you should see the actuator inside do a sync test if it’s not properly or seems rough maybe worth a clean with brake cleaner

So... I haven't really had a look into this much yet.

But when it was raining today I noticed the fuses above the battery were getting very wet, I've since found out that there's a 30a midi fuse for the esp there... I wonder if it's just a blown fuse?!?

I'll get it swapped tomorrow

Update, swapped the fuse, no changes

The thing is there’s no abs light showing which are normally linked

The issue I had the only thing I would have done is changed the air doser as it was leaking (not sure what what time though) or cleaned out the egr valve

Have you pressed the esp button does it come up on the dash it’s turned off

When I push the esp button, it comes up with an esp/asr warning message.

Saturday I'm going to just start taking parts off and cleaning.

I'm still convinced it's a sensor or something??

Update,

I've cleaned the dosser, didn't change anything.

Camshaft sensor was hardly bolted on and hardly connect to the loom, so I sorted that out. It's fixed an oil leak but didn't sort the limp mode.

Then I targeted the egr, my new clamp still hasn't arrived, so I was limited as to what I could do.

I believe it does have a plate fitted

Now here's the strange part... Unplugging the egr clears all faults and takes my out of limp mode.

Plugging it back in puts my esp light on and back in limp mode.

I've ended up leaving it unplugged for now until I decide what route to go next.

You need someone local with planet they can do a butterfly test on the egr

Even with a blank the egr will still do a sync test when you turn the ignition on. If this fails or gets stuck you get issues even though it’s not in use lol

I’m not too sure on the unplugging the egr if it puts it in a default setting

This happens when you disconnect the maf sensor too trouble is what it stops working is obviously the issue

Took it out this morning, driving as normal.

I'll most likely either leave it as is or replace the egr.

There's a local guy with pp, but he charges about £30 for a scan... An egr is only £50 on eBay.

That doesn’t make sense if it’s unplugged it should throw the light straight away as it won’t do it’s test

You can plug it in and then unplug the maf sensor which puts the car in defaults settings but it won’t stop the issues if the mechanism in the egr is faulty

The only thing I can thing which is possible is somehow part of that rubber seal has got in the egr but still doesn’t make sense why it’s running fine without it plugged in

I don't know either, an automotive electrician at work seems to think that if it was mapped out, a dud signal received could cause it to be confused.

Whereas no signal would be fine if it had been mapped out....?!?
