I have a 2006 Jetta BRM manual trans with around 200k miles on engine and 282k on chassis. Long story short with the mileage difference, I purchased the car with 272k miles and a connecting rod hanging outside of the engine block. I paid $300 for the car from my sister n law and had junk yard engine installed for $1800. The timing belt was also done at time of engine install in Jan this year.
After driving the car I noticed that the brake pedal was only for the first few presses when coming to a stop. I suspected there was vacuum leak or possible failing brake booster (I changed the booster in my old 03 TDI and don't want to do that again). Other then the brake issue the car ran great with tons of power or at least compared to the 03 Jetta Wagon TDI I had before.
Now for the problem - Monday I drove from Atlanta to Philadelphia, I've made this trip a few times since having the engine replaced. It ran great as normal but on the way back to ATL I was south of DC and proceeded to pass a semi truck and there was zero power to accelerate. I go to pull off of the interstate and the brake pedal is hard but I was able to safely stop. I checked everything and looks for anything obviously wrong around the vacuum pump/lines. The only thing that I saw that wasn't there before was there is a slight oil coming from between the vacuum pump/head/valve cover. I carefully drove to the first exit and gas station to look over the car more thoroughly but everything looked fine and normal, all of the intake pipping was intact, oil level was normal, coolant level/temp normal, and the engine idled/revved normal. When I shut the engine off and restart/drive it feel to have about 80% power and I car hear the turbo spool but after few mins it goes back to no boost/limp mode. I was able to drive the car a family members house about 100 miles away without any other issues.
I haven't pulled any engine codes yet but I'm sure it's going to have P0299 in there. My first thought was to order a vacuum pump/tandem pump but after reading a few threads here I think I'm going to check a few other things first.
My short list is the following,
Pull the fault codes
Valve Cover/Vacuum camber
N75 Valve (I don't think this is the problem due having two issues)
Vacuum/Tandem Pump oil leak (Gasket?)
Reinspect all of the turbo/intake pipping
Check Vacuum at the turbo actuator (again I don't think this is problem)
My gut is telling me that it's either the Vacuum Pump or Vacuum leak that is going to cause both the brake issue and limp mode issue.
Any advice will be much appreciated.
Thanks,
Steven
