Hi,

I have a rough running engine after a rebuild and I am about to buy me OBD2 reader to help diagnose.

Less important, but I also have an oil service light to distinguish.

Does anyone have any recommendations on tool - I was wondering if I can get away with a generic OBD2 reader (~£25..£35) from Amazon like the Motopower manufactured devices to diagnose and reset the warning lights and then either a hack or additional cheap tool (~£0..£15), for resetting the oil service, or, should I get a more sophisticated VAG device (eg Ansel VD500) which can do both but at £80

Does anyone have any experience with these readers??

you dont need any tool to reset service interval.. othervise OBD 11 ot VCDS.

I bought a modern OBD 2 tool from Amazon - the use case was use on several cars and being of low cost, plus a battery health check feature a winner too.

I feel so ignorant, yet frustrated, that OBD would market a version as 11, especially when OBD 2 is occasionally marketed as OBD II with latin numerals. As a casual skim reader, it is confusing.

but Yes, looks like OBD 11 or VCDS is what is really needed, and for the cost of a garage to diagnose, it is almost worth buying a license...

unfinished review

on my Karoq 2019, 1.5 tsi i had issues to reset service inspection and oil change, oil change i reset with combination of buttons but inspection service i reset thru obd 11. for 10 credits i think which is almost nothing.

it is set to 2 yrs and 30000 kms, i dot follow that program, i do it myself at 8000-10000 kms or 9-12 months (urban driving 90%)

Suggest you look at the reviews of the Kingbolen Ediag Elite which runs via an app on your phone. This has free lifetime updates, where other such as my previous Topdon may charge a yearly fee for updates. This should do the diagnostics as well as reset.
