I bought a cheap ODBII Bluetooth scanner and a paid version of Torq, when I did my oil cooler change , it come up with nearly 60 faults , which went down to 7 which I just couldn't clear.
It seemed to be totally Radom, a few of the same ones kept coming up though , and the van would be fine ,then go on to limp mode after a few minutes.
Changed a exhaust sensor, at £80 as it always came up, didn't make a bit of difference though-still threw up the same code.
The van cleared itself , and started running fine- I think it just' reset' itself after a certain amount of on/off running cycles but the Torq app came up with the same 7 codes.
I was about to buy a new EGR valve at over £250 , until I decided to get it checked on a Star scanner, which came up with NO fault codes, none whatsoever regarding EGR or pressure sensors.
So it's a good gadget, but would now look to buy one like the Carsoft , as it just made me really paranoid, when there was in fact nothing wrong, I am in fact reluctant to try it again , in case it still has faults come up, which will worry me.
