I bought my 2012 Audi a4 Quattro not to long ago (around 3 months ago) on facebook marketplace and right after I bought it I got the code p2188 (system too rich at idle bank one). I have been trying to fix it for months now but I can’t figure out what ...
This is because a competition cam causes a very lumpy idle on the A4, and makes the car more prone to stall or jerk along in stop start traffic, sadly though many ignore this and end up ruining a perfectly good car and having to revert back to a fast road, or OEM cam profile. Comp...
but can probably go up to 100k miles without being too risky. Make sure it has been replaced or at least inspected if you’re buying an A4, as a bad one can mean a new high pressure fuel pump (HPFP) and a bunch of internal engine work that...
The piston rings are sealing element on pistons of the internal combustion engine in Audi A4. The purpose of both valve seals and piston rings is to keep engine oil out of the combustion chamber. When the piston rings are worn or damaged, the combustion chamber of the engine loses pressure....
Using good quality clean burn fuel free of bio elements, the higher octane fuels also tend to burn cleaner. Get the engine up to temperature as soon as you can (don't idle it but just drive it steadily at around 2000rpm till it warms up) and keep the engine operating at 3000rpm for...

APR’s Engineers paid close attention to the balance between core effectiveness and pressure drop through the core, core style and fin density. With fin density too low, pressure drop decreases dramatically but typically results in a core incapable of effectively cooling. Likewise, with fin densit...
I'd never have found a Motorsport camshaft to be a pleasure to live with when on the daily commute because the lumpy idle will make the car prone to stall and smooth driving at low rpm becomes impossible. If you are developing a track car this doesn't matter as you are in the high ...
