PD105 ➜ PD130 Caddy Swaps – Service Update
After a lot of thought, we’ve made the decision to stop offering remapping for 1.9 TDI PD105 to PD130 engine swaps, and these options will now be removed from our website.
This isn’t because these conversions can’t be made to run well—many of the ones we’ve mapped have been a great success. The problem is that every swap is different, and they often involve a mixture of parts, modified wiring, sensor differences, vacuum issues, boost leaks, fuel system faults and countless other variables that simply can’t be diagnosed through a remap.
In one recent case, we spent months supporting a customer, replying at all hours of the day and even while we were away on holiday with our children, trying to help diagnose an issue that we repeatedly explained was extremely unlikely to be caused by the calibration.
The customer also sought the opinion of another tuner. They had their own views on how they might have calibrated the file—which is completely normal, as every tuner has their own methods—but importantly, they also agreed there was nothing within the calibration that would cause the reported boost issue.
We were so confident in our work that we even offered to refund the mapping cost if another tuner could identify a fault within our calibration that was causing the boost issue and fix it. Here we are many months later, and no evidence has been provided that the map was ever the cause.
No tuner is perfect, and every tuner has a different approach. That doesn’t automatically mean a calibration is faulty or that a refund is justified. You choose the tuner you trust, and we’ll always stand behind our work. If we make a mistake, we’ll fix it. If a map genuinely needs adjusting, we’ll adjust it. But we can’t accept responsibility for mechanical or electrical faults simply because a vehicle has been remapped.
For that reason, we’ve decided these PD105 to PD130 swaps are no longer a service we wish to offer. They too often become lengthy remote diagnostic jobs rather than straightforward remaps, and unfortunately it’s no longer worthwhile for us as a business.
We also want to make one thing very clear. This post is not about shaming or naming anyone. It’s simply explaining why we’ve made this business decision. If you happen to see posts elsewhere regarding this situation, you’ll probably know which case we’re referring to, but we won’t be naming individuals or arguing online. We’ve said our piece, we’ve done everything we reasonably could to help, and we genuinely hope the vehicle is eventually resolved.
Finally, a huge thank you to every single loyal customer who continues to trust PDpower Remaps. Over the years we’ve had countless occasions where we’ve advised that a fault wasn’t map-related, only for a mechanical or electrical issue to be found later. Sometimes those customers come back and let us know, and sometimes we never hear from them again—and that’s absolutely fine.
We genuinely appreciate those who trust our experience, work with us to diagnose problems properly, and understand that not every fault after a remap is caused by the remap.
Thank you all for your continued support. ❤️
