NOOB here! I recently bought a 2002 VW beetle GLS TDI with 253,000 miles that I knew needed some love. You would have to give it a lot of gas to keep it from dying when you were starting from a stop when I test drove it and was lacking power (wouldn't go fast). That said to me it needed a fuel filter and possibly a pump (sorry, new to diesel engines). I replaced the filter then the pump/sending unit under the back seat because it was not making a sound or vibration with the key turned. It is still not starting or staying cranked for more than 2 seconds and will only do that the first or second crank then won't fire up. When I bought it I drove it the 1+ hour home, but it was limping (gas pedal floored it didn't want to go over 60), then hasn't fired up to be able to drive it since.
I also replaced the 109 relay, MAF sensor (because of a code) and Air filter. The only thing I can find on the forum is to clean the intake manifold and EGR valve. I would think it would be running rough if that's the case. Still planning on doing that anyway, just not now if I can help it. the codes my OBD2 scanner is giving me are
P0101 mass or volume Air flow sensor a circuit range/performance
P0321 ignition/distributor engine speed input circuit range/performance
p1556 Charge pressure contr. Negative deviation
P0401 EGR A flow insufficient Detected (Why I replaced it, but still there- though I didn't clear codes...)
I got a vacuum pump and made sure the filter and IP were primed. It seemed like the filter was but the IP was not. I got it to fire up for about 5 seconds before it cut out again. It would fire again after that and cut out after 1-2 seconds. Trying to rev it to keep it cranked would rev for about 1/2 a second then acted like I took my foot off the pedal. I'm going to try to clean the EGR valve today. I'll do the intake manifold when my gasket set comes in. If that's not it I'm thinking injectors?
Anyone else want to chime in?? Please?
Update: I cracked the fuel injector nuts and am only getting the 8-10" spray on injectors 2 and 4 when attempting to crank. 1 and 3 just have a drop or two that sits on top of the nut. I'm thinking the next step is to pull 1 and 3 and clean or replace them.
We are moving to another house in town and need to get this driving so I can move it from the old house in about 4 days. Any help is MUCH appreciated!
