james snaithI had an ad blue malfunction on my ford transit custom while on holiday in cornwall,Bolt remaps was very helpful and came out the next day and had me back up and running in no time.Trustindex verifies that the original source of the review is Google.![]()
Iain MarrI used this company to sort out adblue issues with my Vauxhall Combo Life, I was fed up of keep getting warning lights and threats of engine not starting if I continued to drive the car. I contacted Bolt Remaps and they came to me the same day and fixed my problems for good. Unfortunately, due to an error on my part, I overpaid, however, once they became aware of it they refunded me immediately. Both of the staff I was involved with were extremely friendly and efficient and I thoroughly recomend the company to anyone that needs help with adblue problems or engine remaps :-)Trustindex verifies that the original source of the review is Google.![]()

Hiren SharmaFirst of all a massive thank you to the team. I was told that my car would need to have it's adblue tank changed and there was noway out. Costing around £3k. Obviously that's a massive knock. Got it touch with Dean who was prompt with his response and Irwin (sorry for spelling mistake) came and solved the issue in less then an hour. I totally recommend these guys for any of your adblue issues.
