Hi all.
Got a strange problem with my 54 plate TD4. Lost all power on the motorway last week, managed to limp home and put it on diagnostics, no codes stored. So unplugged the MAF and it was like a different car so assumed MAF sensor. Fitted a new genuine Bosch sensor which has cured the power loss.
Now the strange bit. I have a synergy tuning box fitted which has been on for the past 80 of thousand miles with no issues. I noticed that since fitting the new MAF I have loads of black smoke when accelerating hard so turned the box off to see if it made a difference. With the box off I have no power at all below about 2k revs, after this it picks up fine, there is also no black smoke. I've had the ECU reset as I was told this needs doing when replacing the MAF so it can relearn the values, this has made no difference.
This is a list of things I've done:
1. New MAF genuine Bosch
2. Replaced vacuum hoses as some were perished
3. Had ECU reset
With the synergy switched on I have power but loads of black smoke, with it off I have no power under 2k revs but no smoke at all.
Could this be the turbo solenoid and the synergy is just covering the problem?
