Hello everyone. It has been a long long time since I've been on here. But, I finally got a tdi and, well, finally had an issue with it.
Basically it was running a little funny, a bit of a vibration. It would pretty much chatter when I turned to the right. So, for that I replaced the wheel bearings. Seemed fine. Although, it doesn't seem to be related, I was warming it up to drive to work and it stalled. It wouldn't start again. A few days prior I had a few engine codes pop up on it. Using a cheap obd scanner and a cell phone I got three engine codes. p201, p301 and p726. These came out to be all powertrain related and "injector circuit cylinder 1 (201)", "cylinder 1 misfire detected (301)", "engine speed input circuit range/performance (726)" respectively for the above codes.
So, doing some digging online I tought it was my injectors blah blah blah. Well, I finally popped off the timing belt cover and found what looked like bits of belt in there. Although, as it turns out it was not bits of belt but bits of what I think to be oil and coolant mixed up into a crazy thick goop that closely resembled belt. It seemed to be coming from the crank area and started to travel up in chunks to the cam. The cam eventually skipped time. I placed a lock (tool t10050, I think) on the crank and the pic shows how far the cam sprocket is off.
Grant it, these are my theories. I have no previous knowledge or experience as far as working on tdi's previous to this car.
So, I guess I want everyone's opinion on here as to why this gunk built up in the car....the best was to fix it and I suppose prevent it in the future.
I've ordered a high mileage timing belt kit from idparts. I've watched a million videos on youtube. Including loosening the cam bolts and moving the cam back to where it needs to be. I'll include some photo's that will "tell a thousand words."
