*** do I do
OK here is my history. I bought my car a few years ago used, its a 2002 VW Golf GLS TDI with the 01m transmission. I was getting about 45 or more on the highway.A couple years ago I ran over a curb on the passenger side at an angel, and it broke the oil pan, right front tire and some suspension components. VW fixed everything but ever since I have been getting increasingly worse molage and power, and seemed like the transmission was slipping. Anyway I took it to Todd with Dieseltoyz, a trusted mechanic on this site. I had the intake cleaned, EGR cleaned, new Diesel geek timing belt, and had the transmission oil and filter changed. After I got the car the transmission was slipping on exceleration from a complete stop, and then locking up hard, and jerking when I came to a stop. I went back and had him add a little OIL and it seemed to work better for awhile. Now it still seemed like it had low power, and I assumed it was the transmission. So we talked about it and I have read numerous forums on problems with the 01m, and ordered a new valve body. So I am in the Houston area now and replaced the valve body, put a transmission cooler replacement kit. I went to a VW specialist here in Houston and had the VAG COM scan done and he said I was getting a code for the MAF, and actually ran the engine while reading the parameters and said they where way off. I ordered a new MAF from MJM Autohauss, I went to VW dealer and checked the serial number and the appearance of the MAF myself and the one I bought was Identical. I also replaced the g68 transmission sensor the Crankshaft sensor the Temperature sensor,( with the new Green one) which by the way was the p108 code I was getting originally from my scan Gauge II. I cleaned the intake from the throttle body to the intake on top. there was oil pouring out of the inter cooler. I put everything back properly so there is no lose hoses. Now I filled the inter cooler up with degreaser and water, and there where no leaks. OK I went back to the VW guy here in Houston yesterday and he did another scan and flashed the hole computer and still got the wrong parameters for the MAF, also low boost pressure. when I was checking the inter cooler I noticed it had been hit and bent a little but did not leak when I put water in it. He told me it could be leaking under pressure though. Anyway I got a wheel speed sensor signal ( changed the brakes too),. And I put dielectric grease on every connection I put back including the MAP on the inter cooler. Could the Dielectric grease be effecting everything. I intend to clean the connection to the MAF and test the voltage like it says in my Haynes book and try it. I have been going through hell trying to figure this out and I am tired of throwing money into this car. I am also aware of the possibility of the VNT actuator or the Vanes being caked up with carbon, or the Catylitic converter. Please help me if you can....What exactly are the sensors you mentioned from the VAG COM description. By the way do you know where I can find A VAG COM and software cheap.
