Having a nightmare and want to cry!!

scottclelland1 · 03-08-2021, 02:25 PM

Evening all, I have a nightmare on my hands. Car cranks but wont start. Mechanic thought it was the valvetronic motor after doing some research. Replaced it and its made no difference. It fuels, cranks but refuses to come to life.

I've attached the ISTA report if anyone is kind enough to pay it a look. Aside from low voltage faults from it lying for a few months I'm at a total loss and my mechanic is talking about an engine strip down.

Any advice is welcomed

First or all get that battery fully charged or replace it with a new one.

Were any ECU connectors disconnected and possibly put back on wrong, as that can cause all kinds of issues as well?

These cars hate low voltage
Get that sorted first and give it a rip

Get some juice into that battery or try a new battery.
