David McCarthyTrustindex verifies that the original source of the review is Google. The company carried out job it was satisfactory. However, when I made the booking and they were persistent. It was booked for an evening slot, which was fine however they never turned up. I did ring the company however they blamed it on a miscommunication which sounded very unlikely. But the job was done at the end I wish they had better communication. Did ask for an invoice as well but did not receive Or a guarantee, which they promised.

Iain MarrTrustindex verifies that the original source of the review is Google. I 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 :-) Afia WalkerTrustindex verifies that the original source of the review is Google. “Bolt Remaps “company is this best and specialist for any issue with AD BLUE problems.

We cover Croydon town centre and the surrounding borough, including Purley, Coulsdon, Addiscombe, South Norwood and Sanderstead our mobile technicians travel to homes, offices and depots as standard.
If your vehicle is displaying an AdBlue warning or experiencing emissions system issues, our mobile technicians can diagnose and repair the fault at your location anywhere in Croydon. We fix a wide range of AdBlue and SCR problems to get you back on the road quickly.

A dashboard warning can stem from low fluid, sensor failure, or dosing system faults. We diagnose on-site to confirm which.

Your vehicle displays an engine countdown warning if the AdBlue system isn't refilled or repaired in time. We clear the countdown and the underlying fault in the same visit.

Heavy stop-start driving the kind Purley Way delivery vans do constantly puts more strain on the dosing pump than steady motorway miles.

A sensor doesn't have to fail completely to throw a fault code, sometimes it just reads inaccurately.

Urea crystallises inside the injector over time, especially on vehicles that sit idling between deliveries.

Without a working heater, AdBlue fluid can partially freeze on cold mornings, stopping the system dosing correctly until it's fixed.
Fleet vans running the Purley Way industrial and retail units put more strain on AdBlue pumps and sensors than typical private driving we can usually get to a fleet vehicle same-day.
Constant stop-start delivery driving along Purley Way pushes dosing components and NOx sensors harder than steady traffic would.
Rather than take a van off the road for a garage visit, we come to you and carry out the repair on-site.
Our coverage stretches across the town centre, Purley Way, Coulsdon, Sanderstead, Addiscombe and South Norwood.
Yes Croydon has been fully within the Ultra Low Emission Zone since its expansion in August 2023, so a Euro 6 compliance issue caused by an AdBlue fault carries real financial consequences here.
