my tpms readings are no longer reading anywhere near accurate anymore, for some reason o/s/r and n/s/f are now reading under by about 6 psi, also this week on 2 mornings (cold) the dash warning light was on. i have set fronts at 37 psi and rears to 31 psi and checked them with a seperate digital gauge so no readings are correct, but dash says different, i have re-learnt the readings on display. has anyone else had this issue?

Hello

I have a Astra J 2010 1.3 CDTI model. I would like to buy a fault code reader for this car. Do anyone know what works? I have done some googling and it seems that OP-COM and Launch creader 6001 works, but I am not sure. I would prefer to use the Launch creader as it seems much easier, with an Op-com you need to connect a computer, and I am mainly an apple guy. 

Can the Creader 6001 read SVS for a glow plug failure for example?

kind regards
Euro

My 2013 Astra-J 2.0 CDTi auto is starting to play up when taken on a journey of more than 10 miles. Driving around locally it’s fine, but putting it into D after approx 10 miles or more, it snatches into gear quite violently like the clutch has gone in a manual box. If I turn the engine off and start it up again, then it’s fine for a little while. No error codes (using Op-Com).

It's done approx. 65,000 miles. Am I right in assuming it's the AF40 autobox?

The gearbox oil has never been changed,
