Yep, I remember Barry, sadly I don't have the correct emoticon lololol
A lot of inepts are still doing that, and get sent on wild goose chases .................
Why ?? Because the vast majority of modules etc need version coding these days, specific to the Car, so you swap f.e. an Airbag Module, it has exactly the same part number, but it came from a higher specced Merc VW whatever of the same model, so you fit it, light is still on !!
Why, because the car it came from had side airbags and your car does not, (or vice versa), so it needs to be version coded on Dealer Level Kit, also some very expensive Generics will do basic coding on some modules on some cars
I'm learning every day !!
Here's a good 'un .................
I Just sorted out an HVAC fault on a 2014 E Class, 2 Main Dealers and 1 Indie baffled, so they sent it to me
They've had the Dash out twice, changed sensors, flap motors, blower control module, HVAC module etc still not fixed after £1000's.
Anyone know what was wrong ?? ..........................

Fluff etc in the UCP Temperature Sensors little tiny Fan, stopping it drawing the Upper Cabin Air through to the Sensor, 10 minutes with Vacuum Cleaner, and 8.5 minutes of that was getting it out from under the bench and plugging it in
How did I find that ? ....................
Sat in the Car for 10 minutes watching all the data with SDS Xentry as the heater was going beserk blowing hot / cold flat out / slowly etc etc
A tenners worth of OBD reader certainly won't do that
I don't think the guy believed me this morning when I said it was all fixed and ready for collection
I'm not sayin' what I actuallycharged the Guy for that, but it was a helluva lot cheaper for me to actually fix it, than all the money he's already wasted with 3 firms who didn't actually fix it !!
