For all you who are thinking of getting a remap on your pride & joy, BEWARE. Did a lot of research on this remapping lark & it is a mind field anybody can set up & call themselves any expert. Anyway I decided to go with SEDOX performance in sunderland (or formally know as Vsport and PDtuning) wonderful glossy web site good reviews, plenty of bragging of what they can do, bla bla bla, So decide to go with them, yes they where 200 miles away but they’d do a good job wouldn’t they?? Had a golf 170 tdi & audi A6 2.5 tdi to take, golf was a no runner cos the DPF was blocked & had shut down, Trailered the golf down behind the Audi. Would get Audi remapped & management light was on cos I removed the egr valve. Got the work all done in a day DPF removed & a remap on golf, it was running hura hura, The audi was remapped & light out, but needed MAF ( which they done for me) & N75 valve which I did when got home, Anyway it all seemed fine, paid £1074 and headed home, on the way home management light comes on ( the audi that is as golfie’s having a ride home ) and stays on. The golf’s DPF light comes on a few days later also quite a aggressive power band with lot’s of (not a bit) black smoke under acceleration. Some emails later David from sedox suggested I take them to my local garage for diagnostics (DM performance cars pulford) could not find anything wrong & said the light should not come on as it has been mapped out. Back to David & this was his reply—
If there is a light on, there will be a fault code. The light is never 'mapped out', infact anyone that suggests that any diagnostic processes should be mapped out simply doesn't understand the process. Did they check the live data and reset all of the ECU adaptions? We're they using genuine VCDS or VAS diagnostic equipment, or a generic fault code tool?
At this stage I thought ‘this guy is full of carbon’ & I am not getting anywhere, If I took the cars back there all that way to get sorted, is he going to do another **** job? Back to square one. So back to dm performance, he says have you tried simon at ecotec at buckey just 6 mile away? No never heard of them, They do DPF removal & remapping he said. F**KING HELL. After coming down from the sealing I paid him a visit told him the story & he like me thought sedox where good, but would look at the golf first to see what was what. Simon phoned me up later saying he could not believe the car has been remapped this way terrible job, also they had wiped the codes so going to have diagnostic checks was a waist of time as there was nothing to read and they will have known this. Simon phoned sedox to try & make sense of his remap, But in the end Simon sourced a standard VW golf file started from scratch, remapped it and sorted all the issues, (no problems with sensors etc) and running much smoother now, no lights coming on, also sorted the audi as well, Many thanks to you Simon as you are down to earth, not full of **** & know your stuff. As for David Appleby of sedox you are one of the sharks and will No doubt will have a clever explanation for this, but the net is moving in.
