LeeT5's V70R Project

[LeeT5]

Car has developed a boost leak at around or just above 17 psi under load in 4th/5th/6th gear.

Fault code is ECM 6806 - Turbocharger (TC) control system flow fault - Flow too low. Car boosts fine until 18 psi then drops to 7 psi and won't drive normal again until restarted.

So far I've removed and cleaned the TCV, BPS and MAF. I've also swapped the TCV with a known second hand working TCV, same fault still present.

Cars getting booked in for a smoke leak test at Volvo next week, so I'll keep you all posted. Other than that, it drives fine and after every drive cycle, the boost is restored from the ECM safe value of 7psi until I hit 18 psi again.

For now, she remains parked up....

I was given it by my Dad many years ago. No idea where he got it from and I doubt he'd remember.
It's a Quality UV reflective cover with soft underside, elastic corners and waterproof/breathable membrane. Works very well.

I wouldn't get one from halfords as the XL cover (you'd need) is very heavy in comparison to mine. I think mine came from a proper car cover company?
