V70 strange fault today
Whilst driving today, my V70 developed a fault that felt like it was misfiring (felt like my first Mk2 Escort when it had two knackered spark plugs). Two warnings were displayed on the dash. DTSC service required and Engine system service required.
I stopped it and restarted - same codes and issues. Used my cheap OBD2 reader and the following codes are showing. P1264 ECU Cylinder 4 High To Low Side Short U0415(68) Invalid data received - anti-lock braking system (ABS) P2425(00) EGR valve cooling valve - open circuit Any ideas of the issues and the fixes?

I think just diagnosing from those three codes alone will be a task and a half.
The only input I have is based on another vehicle brand. On my Smart Roadster when an ABS sensor fails or the reluctor ring on the driveshaft splits or becomes overly rusted, the car develops a misfire. The last occurrence was split reluctor causing a rogue signal, previous to that a sensor just failed. Perhaps you could take a look in this area. What you really need is Vida so you can see the live data and use the diagnosis portion to work through. Code readers only - They are for the wizards amongst who recognise a series of codes from previous experience. Perhaps a wizard will be along shortly... |

Does it do it whilst cornering at relatively low speeds? Like driving around town?

Remember that the ABS not only controls brakes but can cut fuelling and/or throttle - it will be linked through the ESP which works by controlling brakes and engine speed the latter of which might be the misfire you have experienced. Let us know how you get on |

No, it just cut in without warning on an A-Road at around 40mph. Constant misfire and worse with more throttle, but not noticeable with foot off throttle. I only drove it home.
Starting it since, the misfire now continues at idle in neutral. Like a cylinder isnt firing at all
