I’d say in the 6 weeks ive had the hawkeye its saved me probably £100 + in diagnostic time plus more in me being able to diy fix the problems. It also diagnosed my mates D3 power loss and smoke issues in 5 mins (split intercooler hose). Saved him also.
If the Foxwell jobbie does the same as Hawkeye it will be great.
The dongles do allow greater range on the Hawkeye but most are slightly obscure. I have the blk and red dongle as they came with it.
