Extremely happy with the way ECUtesting handled my Dash board problem as it was damaged in transit. Sent me photos of damage, fixed the initial problem along with transit damage. No problem with reccomending ECUtesting to anyone with dashboard problems.

used these several times used these several times 5/5

We have used these guys a number of times now and can not fault there process. We would defiantly recommend them. We were impressed with the lifetime guarantee that comes with the repair and the quick and efficient turn around of each job. Well done guys .
