I have removed and clean both egr and shudder, and the shudder is opening and closing fine manually. Most likely is the shudder isn't clsoing when the engine is turned off? MVB 074.4: Adaption status: (Run) then it should change to (ADP OK)Īlso, are there any ways to check the antishudder valve, I've been having engine shakes when shutting off the engine. Should I input something in 1, 2 and 3? Where is 4th input? I don't understand the meaning in the ross-tech manual: (EGR)_Valve_Adaptationīut, what do I do from here, I don't understand what 'MVB 074.1: min position in volts' means, also the latter 'MVB's'. So I'm just trying to do all of my research before I go replacing things that don't actually need replacing, in an attempt to start getting >50mpg highway, and hopefully, with some hypermiling techniques - over 60mpg.I'm trying to figure out how to do a EGR adaptation with vcds. So it's just a good idea to do that anyway.Īs the car feel underpowered to me - it can still rev up to 5100+ (haven't tried much more than that for fear of breaking something) - I'm guessing it's either clogged intake, dying MAF, dying thermostat, or possibly dragging front brakes (already replaced rear pads/rotors, and they aren't dragging. I have every single service receipt since the car was new (great prior owners!), and that cleaning service is nowhere to be found. My guess is that the EGR/Intake is clogged. However, I've never gotten anywhere near that since I got back to TX. When I drove the car back to TX, I got 56mpg on the tank (accurate measurements). I bought the car in Ohio just over a year ago. Just wanted to make sure they were all available in the free version of - Thanks.

I'm not averse to buying VCDS Lite in the future, but if I can save another $99 now, it will help me out immensely in the short/long - I'm in San Antonio, TX, but I won't need help, as I'll have my wife running these logs in the passenger seat while I drive. Has anyone done this with the free version of VCDS?īefore you say, 'Go buy it, it's only $99!' (I already have a USB-OBDII cable) - the whole point here is that I need to save money. I have the free version, and I'm curious if the free version can do logging of requested vs actual turbo boost, and the necessary logging to see if the MAF is going bad, as well. I want to check the MAF performance as well as turbo requested boost vs actual with VCDS.

Next oil change is at 183k, and I want to clean the EGR / intake manifold, all filters replaced (including fuel filter), and make sure the MAF is functioning properly, as I'm currently averaging high 30's MPG, and I want to get into the 40s, 50s, and 60s.

The car is an 02 Golf with ~181k miles on it. I want to clean out my Intake Manifold / EGR, as I suspect it's clogged up with soot.
