“The spanner warning light came on (coincidentally?????)?at the same time that the car needed servicing.
Ford wanted a stupid amount of cash to check and even more to remove the spanner if all was ok
Cue the code reader - no faults
Get the car serviced
All is good
This has saved me over £50already - happy days”
“Pleased I bought this. I'd assumed a fault with the fuel as my partner had run the petrol right down to nothing but decided to buy this just to check. It showed a fault code to cylinder 2 and so I replaced all the spark plugs. Now runs fine and I was able to delete the engine warning light using the code reader once I'd changed the plugs. Well worth the money even if I never use it again.”
“I bought this to clear error codes on my 2008 Vauxhall Astra. I had replaced some parts but the error codes and symptoms were not gone. I cleared the codes with this code reader and the car was immediately back to normal and has been fine since then (400 miles). I wasn't expecting that, only to see what codes came back to further diagnose the problems! This obviously isn't a full scanner etc and very basic, but it worked great for what I needed it for with the added bonus of presumably resetting the car's learned data so that it was able to run properly again once the parts were replaced.”
