This one I had was also very intermittent, a couple of other techs looked at it previous to me and the dtcs were always stored not present. When I first checked it out I couldn't fault the APP. I checked connections at the Ecu (near side under front bumper) then jumped the signal(s) with the 5v ref ...

I had these on a Astra H before Xmas, scoped the sensors and I was getting drop outs on sensor 2. Pedal fixed the fault.

I think my DTC description was low voltage and also I had a signal low....

How do you guys rate the snap on verus for the uk and European market?

I deal with http://www.blythequipment.co.uk/texa_cars.htm a family run company down south, excellent customer service. I've rung them a few times when I've had problems and there very helpful. He's called Jonah, mention me if you get in touch.

I also have a Texa (navigator) running ID4 version 46. Not currently on contract. Who do you deal with for your texa?

Also have a proper tech 2 which is bang upto date and a opcom.

Andy I've only been with Kia for 6 months but I do know they have problems with the items I mentioned. Just checked a few course notes and the egr figures do seem correct. You may have mentioned this before but can you see egr and maf relation when the egr opens? The maf should decrease as you proba...

When the egr was replaced, was the cooler cleaned out? These can block up solid. Are the dpf temp sensors reading ok. As far as I'm aware the egr should be off @ idle but would have to confirm with some of the Kia techs at our dealership.

Hello there

What car have you got and what's the reason behind loosing the cat? When I had my track car a few years back I just used a O2 simulator.... Did the job

Nice little case study Andy, I never had a problem driving my Elise with no servo assisted brakes

How do you find the texa idc4? When your looking through the live data screens is it slow to change pages? I think my laptop needs more memory.

Very common for the throttle body failing on the Z16xep, done a few in my time.
