Loss of power no faults
My S85 is causing me headaches.
It's really down on power at low revs and the power button makes next to no difference. Its dead below 6500/7000 rpm.
Only fault showing is a bank 2 O2 sensor heating circuit.
It feels like it's massively pulling the timing.
If you floor the throttle below 3k you feel it go then pull back/hesitates. It's feels ok on 1/2 throttle.
With dsc off, rolling in 1st gear @ 3k rpm on a wet road i can't provoke wheel spin!!!
I thought maybe MAF's so drove with them disconnected. It's worse.
Car is completely stock.
I'm wondering if it's VANOS related. Any ideas????
I've got inpa (It's all in German though) can I test the VANOS with inpa??
