I recently bought a '04 V10 Touareg with 107K+. I bought it with a few issues but I have my 7.3L PSD as my daily driver while I work them out.
First, the center support bearing bushing for the driveshaft was out. I replaced that with the Vertex Drive Shaft Clamping Bearing Support Mount. Hopefully it will be the permanent fix they claim. I do have a heavy vibration when getting up to speed around 40mph and 60mph but that might be related to another issue I have yet to diagnose.
Next, the exhaust was bellowing out white smoke. I pulled both the lower intercooler tubes and oil poured out. I have since removed both intercoolers and cleaned them and the upper tubes up to the EGR valves. The white smoke has cleared up significantly. There are still occasional times where white smoke pumps out exhaust. I think next I'll take the intake manifolds off and clean.
I have removed one of the lower cats and seen that they are pretty clogged up. I plan on making downpipes when I'm ready to do the tuning. I know those clogged cats are not doing the turbos any good.
Another issue is a rough idle but I hope that might be addressed when I clean the intake manifolds. My Autel shows codes for random misfires but I can't view any PIDS. I am going to purchase the Ross Tech to help better diagnose. My worst fear is that I'll need a camshaft or two.
I plan on doing all the work myself. How far can you tear into these V10 without dropping the motors out?
I am excited to tear into this motors and see how it works. I haven't worked on many TDIs. I mainly work on Powerstroke, Duramax and Cummins (order of preference). What are some other issues I should look for? What are some other upgrades or aftermarket products available for the V10?
