Hi all, I registered just recently because I wanted to ask a specific question to which I couldn't find an answer in past posts. (If I missed something, please feel free to direct me to it.) So here it is:
My 1999.5 Golf TDI hasn't been able to pass inspection in over a year due to the check engine light, but the car runs great. I have one of those knock-off VAG-COMs and the code it's showing is P1403: EGR regulation deviation.
I've replaced the N18 and N75 valves and all the vacuum hoses in that part of the system. That didn't help. I've also replaced the MAF sensor, which helped for long enough to pass inspection last time. CEL came back on after about 50 miles.
On the recommendation of KermaTDI, I had the intake manifold and EGR valve cleaned. The mechanic said everything was severely coked up. The car had been running fine, and still runs fine -- and that's great, but I'm out almost a grand and my car still won't pass inspection.
The car makes a high-pitched squealing/whistling noise at higher RPMs under load. Doesn't make the sound just revving in neutral.
There are two holes in the exhaust. One is just downstream of the flex pipe and the other is a foot or so downstream from that. I did my best to patch the first one with a Miller Lite can and a bunch of pipe wrap **** from AutoZone. I patched the second one with the same pipe wrap stuff. I wire-brushed all the rust off and followed the instructions. It still sounds like it has an exhaust leak, though, and after resetting the codes I got another 1403.
One more thing that may or may not be related: I have a slow coolant leak, but another mechanic pressurized the system and said it held. I have a feeling the leak is in the cabin heating system, though, because I can smell coolant whenever I turn on the heat.
So what I want to know is whether the two exhaust leaks I mentioned are enough to throw the 1403 code. And if not, what else could be doing it if the N18 is good, the car runs well, and the intake and EGR are clean? I've double-checked all the vacuum hose routing, and it's correct according to a diagram I found here in the forums.
My wife wants to sell it, and I want to fix it. I can't afford to have a mechanic throw money at it. Another question I have is how much is it worth? Intractable EGR code, runs like a top, 2-door, alloy rims, manual transmission, 180k miles, old tires, slight rust on the front fenders, decent-for-20-years white paint, fair interior, old tires, roof rack, trailer hitch, newly cleaned manifold, timing belt and clutch at 160k, and good glass?
Any help would SO much appreciated. And if anybody knows a VW guru near Ithaca, NY, that would be great too. I like the shop I take it to, but they don't pretend to be VW or diesel specialists.
Ok, thanks in advance! Take care everybody.
