Q: How long does the Remapping take? A: We need around 2 Hours to remap your vehicle. Q: Do I come to you, or are you mobile? A: We are based in Havant however we can travel to you at a cost of £1 per mile (from PO9 1JH) to come to you. Q: Can I wait with the Car? A: No, you cannot be inside our unit when we are working. Q: Why don't the manufactures do this from standard? A: Manufacturers have to allow for the fact that the vehicle could be going anywhere in the world. This is significant because they have to allow for constantly hot climates very cold climates, and very poor fuels. They also have to allow for customers abusing the car, for example completely missing services. When we re-map your vehicle, it’s mainly for performance, however, it is also fine tuning the engine to run perfectly, as each individual engine is different. When we're finished, your car will run as it always should have done. Q: Can any car be remapped? A: Most diesel vehicles can be, just get in touch and we will check for you. Q: Why is re-mapping a better option than a plug in tuning box? A: The option other than a proper re-map is a plug in tuning box. We often get asked which is best. The simple answer is a full re-map. A tuning box simply gives false sensor values throughout the complete rev-range. The ECU is constantly told (or fooled) that not enough fuel is entering the engine, so it over-fuels the engine to gain performance. Although performance gains are made, these are at the cost of high emissions, higher engine temperatures, and general poor running of the engine. Many sellers of tuning boxes state that they are completely invisible, as they can be removed. This is not the case, diagnostics tools will show errors which have been caused by the incorrect fuelling. Problems related to tuning boxes are poor running, black smoking from the exhaust, rough idle, and clogged injectors and even engine's cutting out. Q: What if I’m not happy with the Remap? A: Simple, we will put the car back to standard and give a full 100% Refund. Q: If in the future I decided to sell the car and would like it back standard could you do this? A: Yes we store all original ECU Maps in our Database so it’s a simple case of just remapping the original map back to the car.

One of those jobs that just kept going wrong!

Yep, this was one of them, a simple manifold swap was all that was required but no, this T5 decided it had other plans. The first stud touched snaped, the second one, snapped, third…. You get the picture, these were seized in place and no amount of lubricating was going to get these loose.

This usually isn’t a problem but these were the ones with limited access to get tools in to replace the studs so sadly the engine had to come out. So now we have the engine out and on inspection the DPF was falling apart so we moved the broken block inside that was surrounding one of the temperature sensors only for that to be dead and upon trying remove the sensor the boss split and ruined the thread and DPF.

Then the other sensor was seized in due to age and heat plus one of the pressure sensors pipes was damaged. Finally, upon replacing two sensors that refunsed to come out of the old DPF the only one that came out ok was also faulty. DOH.

This has had an after-market DPF fitted as the genuine ones cost a ridiculous £4296.24 plus vat excluding any sensors needed (come on VW that is taking the p**s!!!!).

Anyway, after way too many hours and this van being on and off the ramp way too many times it is up and running with a clear DPF too.

We look forward to not seeing this lovely patient customer for a bit now after performing open wallet surgery on him 😉

2021 VW T6.1 (Bosch ecu) 110 bhp van in for remapping.

This is using the Bosch MD1CS104 ECU that we must send to Auto Tuner for unlock. This is a 3 day turnaround on average.

At stock this made 107 bhp and 237 nm of torque. After remapping this left us with an amazing 188 bhp and 345 nm of torque. This is stunning tuning and no one tunes them better than Pendle Performance.

We are the only remapping company in the UK listed as a Which Trusted Trader for a reason.
