T6 DPF woes, mapping advice needed !

[quattrodave]

Recently had my DPF gutted and remap software installed by a local garage in the north east.
Set off on a longer journey and coil light came on flashing and EML also.
Van was smoking and underpowered.
Back to said garage and they uninstalled the map and then installed in again, apparently fixed.
Its still underpowered and smokes slightly as well. I've lost faith in them now so looking for someone North East based who can help sort out the mapping.
Any ideas please ?
Thanks

Get a refund because it obviously didn’t work as expected and buy a new DPF.

I should have said that the garage contracted the mapping to a t
hird party and they're blaming him so it's not straightforward.
I just want to move on and pay someone else to sort it

In legal terms you contract was with the garage not the third party.

Yes I get that but just looking to move on....
Thanks for advice though

Most vehicles live trouble free with the emissions systems in tact.
As it’s illegal to tamper with emissions control parts (and renders your vehicle not road legal - so possibly not insured either) I can’t see many people would do it and yet there are quite a few examples where the vehicle develops faults after being tampered with so proportionately it seems a lot more likely to develop faults after going down this route.

IIRC Baz Meredith on YouTube had a Polo in last week with a similar issue to yours - might be worth a look and if you search the forum you’ll find some threads along the same lines that might help.

To be honest I’d second the advice above - get your money back (who wants to pay to have something made worse? Even if you’re made of money surely it’s the principle?) and put it back as it was designed, thereby remaining road legal and less likely to have issues (reliability, failing MOTs etc) going forward.

Thanks for that, I'm thinking of options at the moment.....

Removing DPFs will become a very expensive mistake when the MOT test catches up with this. I'm very surprised it hasn't already tightened up, as they have known for a long time that DPFs are being removed, and the current test can't detect most of them.
The people it will hurt most are those that buy an older cheaper vehicle not knowing the DPF has been removed, then suddenly face a bill for several thousand pounds to fix the MOT failure. Or more likely, the vehicle will be written off.

This is what a post I saw last week seemed to be based on - seller had mapped the car, messed with the emissions stuff, caused issues and thought best move it on without mentioning any of the mapping/tampering before it gets expensive.
It’s happening already.
As you say the Gov know it, are looking at it already (have trialed some bits like getting MOT testers to take photos of certain things) and will no doubt roll out enforcement at some point.
