Bosch ECU remap - finally?

Yeah! It's underneath the battery in a very awkward position with a security cage over the top with shear bolts, holding it on, it was a pain!
I'm using a local guy to me who's a bit of a whiz with all of the auto tuner, tech, I'm having EGR + DPF + ad blue deletes, 150 to 180 map
Will the van pass an MOT if these all deleted?

If hes caught, yes, but the odds are slim in the extreme...at the moment.

Will insurance be void?
Yes-ish. 3rd party liability remains covered, but they wont pay the policyholders own losses. In the event of an expensive claim or serious injury/death they will plug in and  will detect it. You could declare a performance map and everyone is happy, but the unlawful deletions would torpedo them in those circumstances.

i had a T5.1 that was remapped, it was written off last year and the insurance paid out without knowing. Chances are, copart will pick it up without checking its been remapped. Nobody cares unless the police are involved and check the vehicle out
 
It likely wasnt a huge payout if it wasnt checked. Try it again on a £65k van thats been smacked.

Having worked in collision investigations I can confirm they are very likely to check in the event of a serious injury or death, or a big number payout. Suddenly they will care very much indeed - I've unlocked the pound gates enough times to let them in. The vultures at Copart wont get a whiff until the dibble say they can.

I paid £4200 for it and they settled at £7600. I’d say it was a huge pay out really
 
Well there you go. They aren't likely to pay a tech £1500 for a day out, travel, data analysis, and report, and the potential onwards costs of a court summons for £7500.

Bottom line is the odds of being caught are slim indeed, but if someone in that situation does get found out itll be in a situation that causes them the most pain financially and potentially criminally. Hes a big boy, he takes his chances.
 
Well, I wanted to ask that in several "tuning" threads, but I may ask it here as well.

Don't they test exhaust gas for fumes/particulate at all in the Kingdom?
A friend of mine was caught in Italy at "MOT" some 8 years ago for having drilled through the DPF and had to write off the van. That was still an Euro 5 .
Myself, even before, around 2010, l was pulled out by the municipality police of Como (IT) and tested for emissions on the spot (and passed, my Renault was new and unmodified). They were stopping only diesels.

Or is it understood that for passing the UK MOT without a working DPF you NEED to go to a "dodgy shed" where for a fee in cash everything passes?

Again, not judging or preaching anyone, just trying to understand how it works over there.

Yes they do.

Strangely enough, for some engines (i think DNAx), workshops have a recent advisory to drill a 3mm hole in the DPF if the EML comes on and something shows up related to emissions. Something to do with pressure I was told by a VW workshop, although the location of the hole seems to suggest it might be more to do with condensate.
Factory DPF's are being produced with that hole pre-drilled now.

Yeah I've got a DNAA with factory hole.

In the UK, the emissions equipment is visually inspected for tampering, and a smoke test performed. A good condition engine will pass the smoke test without a DPF present.
Future MOT's will tighten up, and probably will test for particulate size as well as opacity. I can also see that a sooty tail pipe will also fail, so any cracked or missing DPFs will fail.

The MOT diesel smoke test is very basic and can't itself detect an absent DPF. The test pre-dates the introduction of DPF technology.

However, the DVSA has had selected MOT stations trialling a "PN" test, which can detect missing DPF's. The trial isn't part of the official MOT but is being used to gather data in order to establish how wide a problem sneaky deletes has become. Sadly, the data going back is sufficiently alarming that the DVSA want to incorporate the PN test into the MOT, as most of Western Europe has already done.

The only thing holding it up is arguments between industry bodies and the DVSA because of the cost of the gear, with the industry wanting more time for garages to acquire the gear in a phased manner. As of last year the DVSA wanted a 2028 introduction, but its probably now too late for that short a time frame so extremely unlikely. 2030 seems more feasible. When it happens, and it will almost certainly come within 5 years (I've a friend who's a bobby attached to DVSA who gets the internal gossip - DVSA are being leaned on heavily by central government due to legally binding air quality targets), there are going to be probably millions of people finding themselves lumbered with vehicles subject to prohibition notices that cant be driven until repaired, and worthless because no one is going to buy one without a ticket.
 
Devils Advocate - so not shouty and being snooty.

Based on Sasquatch inside info and other info on the forum, at least 4 things to look at:
1) environmental,
2) legality
3) price
4) potential pros/cons

1) Environmental:
The engines are quite complicated compared to the 'old days' and without the mipmaps and the goujons installed, will give more NOx, particulates and possibly other nasties. However, the mipmaps and goujons do result in extra useage of diesel so reducing mpg slightly.
Also, however, the NOx and soot doesn't just 'disappear'. It gets burnt off, so producing other combusted gasses and products that governments are happier to turn a blind eye to (If you don't test for them, then there isn't a problem) rather than the demon CO2 and NOx and larger particulates. So - these aren't 'clean' engines with the DPF/adblue in the sense that there are still emissions. No such thing as zero emissions unless you have a hydrogen powered engine (if you discount water + heat) or an electric engine powered by renewables. We won't go into production/mining/transport/slavery in this post just yet.

2) Legality:
At the moment, although illegal to drive on roads with emissions devices that have been tampered with in any way, it is unlikely (not impossible) that you would be caught out for the next 3 or 4 years unless in a major accident or have a major insurance claim, or are rude to the wrong traffic officer (as in, one who knows what a DPF looks like) or that rare occurrence, a checkpoint looking for such anomalies (you'll know it when you see it and are just about to pulled into one).

3) Price:
The price of a new DPF is about £800 to £1200 ish. Expected to last over 5 years(?) depending on driving style. The price of a new Adblue system is about the same (expecting not to replace it within the lifetime of the vehicle but a few are unlucky in this respect).
The price of a remap and blank DPF is about (at a guess) £500 but would have to be put back to OEM in 4 years time at a cost of about £800 to £1200 (ish).

4) Potential pros/cons:
With a remap - in theory - not insured and illegal to drive on the road.
With a remap - get a bad one (not all are good looking at forum) and it'll cost you loads to put right
With a remap - get a good one and you are cruising.
With a remap - either mapped for extra va va voom OR for extra mpg - not both.
You pays your money and you takes your chance - but all this talk of taking a vehicle to someone who has just come out from having a holiday at his maj's pleasure and giving them money to fiddle about with your engine/cpu, that is too much for me to bear. I know that doesn't apply to many (more than 1) but at a guess, if a garage that is doing this gets it wrong, I can't see what comeback you have as you have asked for something illegal to be done in the first place.

Admittedly, before reading lots of stuff (mostly on this forum as I can't be arsed with most of the rest of the internet), as soon as I got my van I was doing research into getting rid of all the 'potential problems'. Less stuff on there to break, less stuff breaks. Now I look on the system as a bit of a needy friend. All good for most of the time but will eventually have to replace it - like brake pads.

Personally, If you want a cheap vehicle, then go get one - but, each to their own.

Actually - a quick edit - won't let me do it in the post.

If after 4 odd years of having a mapped engine and not using DPF systems and Adblue systems, then it might cost a bit more to go back to OEM as would think, especially, the unused Adblue system will be knackered unless it has been completely flushed through at the time of mapping (doubt that happens - but I could be wrong). There might be other knock on events also but those in the know are better to comment.

Should have clarified - taking out emissions remap - rather than 'remap'.

Actually - I should have put a title on it saying that it was about taking out the hardware.
Cheers Bav - feel free to edit that post if anything is iffy in there.
 
Remaps are legal and insurable (provided they're declared).
That must be another fantastic freedom feature of thr UK system.
Respect.
I reckon in most of the world you need at least a written approval from an engineer of trade and a new paperwork from the authority.
All the above in practice never happens (legally).
The fact that they trust you as a Citizen to do and take responsibility for that is impressive

On the funny side, in UK you must be concerned of LED bulbs , even the few ones thar are worldwide accepted (and that, IMHO are absolutely safer than halogen).
