You could disconnect the battery for a while, and then reconnect, the ECU will then go into a new learning curve, might not hurt.
What turbo pressure do you get? You need figures to post here, Not that its correct by the mechanics. Usually if mechanics say its correct it means they haven't done it!

Update

Todays drama after replacing the intercooler and driving about 120 miles over the weekend with less smoke and more performance, on the way to work this morning i noticed as i drove through our village that i had no performance whatsoever, in that at 3000 rpm i was doing 20 mph and VERY slowly gaining speed, i noticed no loud whooshing sound and also not the ammount of smoke from the back i have come to expect, it was unsafe to drive on the motorway, so i dropped it back off at home, i may get the AA to look at it during the day, i had no messages on the dash and no extra lights. I am hoping that with the extra pressure now passing through the system i have blown off a turbo pipe, i am hoping that i have not blown a turbo!
I am frankly getting pi**ed off with this i need this car to work, and at the moment i am getting the Land Rover experience
Any ideas anybody ?

Which year car it is?

Disconnect exhaust pipe together with cat from the turbo and run a car. That can be a PITA job. I have a feeling catalyst is clogged

[chris810]

I know what you mean but it doesnt sound expensive enough for this car

[moorgate]

I think I have the same problems (plural) - in some circumstances I gas the guy behind me, other times, not. I've had the turbo rebuilt with one of the common overhaul kits, replaced the bottom rubbery intake pipe (which goes all squashy with oil and lets air in around the crankcase breather pipe), had a duff injector overhauled (no difference), swapped out the EGR: I suspect it is actually something like a wastegate actuator not fully closing until the engine is fully warm. That might be weak vacuum, or it might be just crud around the whole moving part assembly.

Like you, I find that quite a lot of indies are just groping about in the dark. When I pointed out the squashy pipe problem, mine actually said "there wasn't an ECU code for that". Well, d'oh - it's a lump of rubber pipe!!

Had the car into main dealer today had standard software put back on it still in limp mode but now showing a code, DPF sensor faulty, they swopped that for a "known working spare" and now showing DPF missing! And still in limp mode.

They wanted to change the DPF ( is there also a cat ? ) but i have a local tyre exhaust shop we use at work for things like this going to do it Friday, at a lot less that Main Dealer Prices.

The main dealer were going to run a regen but could not as according to the car it does not have a DPF. Would a clogged DPF show as missing ? It makes sense to me to say that its clogged, i have been putting a vast ammount of particulates down it lately.

Once that is done we will now see what the next fault down the line is, at least i am getting error codes now.

So if its got a DPF at least now (the rest of us) know its a euro4 engine.

I also had problems recently with the DPF temp sensor and ended up replacing it.

The car has a DPF and a CAT (which uses a separate temp sensor).

Ive never known of a car 'not knowing' it has a DPF.... this would again make me question what has been done to the ECU in the past... a bad DPF delete perhaps.

Have you considered taking the car to a renowned and knowledgeable ECU mapping specialist - im thinking along the lines of MTE/RiCA/Shark and having the DPF professionally gutted/removed and then proper DPF delete S/w written in.


It almost sounds to me like someone has done a 1/2 arsed job of remapping the car and at the same time has done a Sw DPF delete, without actually removing the DPF.

[chris810]

I had the engine management software reloaded, ( confirmation reload they say ) and they also recoded the injectors to the ECM ( dont know what that means ) I wanted it taken back to standard so that i could start from a known base. I would assume that the DPF would now be seen by the software.

I still dont know if the dpf issue is putting the car in limp mode, i have used V Tune in leeds several times in the past for remaps etc so i am dealing with them at the moment, i dont know if i want DPF delete sorfware written in, if it goes faster than 40 mph with better acceleration than a 2cv then i will be happy dpf or not, if any of these software guys are more than 40 miles away from Pontefract ( ponte- carlo as its known locally ) then at the moment they are out of my range.��

Next time it would be nice see that details about engine are provided in the first post , not in the 26th

I dont know tbh what to suggest for you because now only God knows what has been done with the car before you bought it.
I assume some trouble codes related to dpf been deactivated and thats why no single message came up on the dash also diagnostics tool been showing nothing.
Its very possible dpf is gutted but was not disabled in software and you had problems. hard to say but now you know the dirrection where you need heading to.

DPF is not Catalyst

You need to find a good remapping specialist who is familliar with exhaust to check whether dpf is gutted or not. If it is - carry on reprogramming dpf and I suggest EGR valve too.
If you want - do remap as well to gain some more power. So it would be 1 shot - 3 rabbits. DPF off, EGR off and remap.

All sensors like exhaust temp sensor, dpf pressure sensor must be in good working order

My car is remapped also dpf and egr disabled. Runs fantastic but not now! i have injector failure

Must inform you dpf removal does not comply with the law even your car emission is in tolerances. Removed dpf doesnt catch soot particles what it has been designed for.

The problem is, I still wouldnt be 100% sure you are working from a known base.

Im not familiar with how this stuff works, but if the car has had a 1/2 arsed job of a remap and DPF delete done in the past, it wouldnt seem unreasonable to me to suggest that even after loading the OE software back in, the DPF element of it is still somehow messed up.

Dont forget that dealers in general are not too knowledgeable with this sort of stuff.

I agree with DIRO and reinforce what I suggested earlier. Find a trusted, well known and established diesel ECU and exhaust specialist. Have the EGR and DPF written out of the ECU, have the DPF professionally gutted, and perhaps a proper remap at the same time.

I think you have probably got quite a complicated ECU/DPF problem and I dont think the dealer will have the necessary skills to properly diagnose and fix. You will more than likely throw good money after bad fitting new parts to the car with no solution.

There are lots of RICA dealers in the UK. Quite a few in West and South Yorkshire it seems:

They offer a proper DPF delete and remap service.
