Help Please !

Post by Benscab123 »

So today, after having multiple faults including parking brake fault , gearbox fault , EGR, esp and others, the car decided it didn’t want to go into ANY gear ! It eventually did after a couple of minutes but the car is really worrying me now.
I’ve checked the battery and all seems good (12.7 with engine off and 14.3 with it on tickover). My thought are either something to do with the fuses or a broken wire somewhere, but I don’t have a clue where to start looking.

If it me, I would start with the basics, All multiplugs, earths, etc, Swop battery for known good one if you have access to one. Pull the multi plugs open and look at the contacts, they usually show signs of discolour if they have been overheating, creating a high resistance.
Then if happy with all them, try a BSI Reset.
Also, is your diagnostic kit making good connection all the from OBD socket to machine.
Always try easy stuff first

Already tried bsi reset and that didn’t work. I’m wondering if it could have anything to do with the brakes as I’ve been getting what sounds like squeaky brake noise from the rear even when I’m not applying the brakes and just slowly reversing. Only other thing I can think of is maybe something to do with aftermarket EGR valve.

Did a bit of digging on diagbox and came up with these faults, the only one that wouldn’t clear was P0405. Also did an actuator test on the EGR and couldn’t hear anything .
