Golf IV / Jetta IV :: 2005 - Car Would Not Accelerate Properly From A Standing Start
Aug 13, 2016
Crank position sensor was replaced a few months ago. After that noticed that it would not accelerate properly from a standing start. No jerking or anything, but way back it used to be able to spin the front tires a bit, but now not getting that needed acceleration. After hitting 15 or 20 mph, then it's back to normal and road and highway speeds are nice with power.
The reason the crank position sensor was replace was on account of intermittent no starts. That's gone away, but now this acceleration problem. Could it be a leaking air from the outside into the intercooler? Would a VAGCOMM show what's going on? Golf TDI 2005...

My 2005 Jetta gli 220k miles just spurred going down the road now every time I accelerate and get into high Rpms the Ac vents start to blow harder and feels like loss of power. It's fines at idle and first gear but 2nd and up its does it I'm stumped....

OK so been about 3 weeks and still cant get my car to start. So far I have installed a new crank position sensor, speed sensor located on top of transmission, new spark plugs, new fuel pump had battery tested and charged. I have tested the fuel injectors and get 13.1 ohms at all injectors tested the new crank position sensor and get 800 ohms. I just had car scanned with VCDS scanner and the codes that come up are. What else can I check.

So my little brother bought a 2005 Vw gli, and it's been pretty good on him so far however, one day he was coming back from work and the car suddenly shut off on him and we haven't been able to get it to start.
(Haven't really been able to actually diagnose it fully since this is his second car)
Did the typical unplugging of the air mass sensor to see if it was that. Checked the relays to see if they clicked Checked all the fuses Checked the ignition switch Checked to see if fuel is getting to the injectors Checked some of the grounds( can't locate all of them)When I turn the key, the rpm needle moves a tiny bit

Last Saturday I got gas on my way home from work then let my car sit all day. Sunday morning i go to start my car and it starts terribly along with a very rough idle. The ride to work was hideous as the car could barely climb a hill (max 25mph and high RPMs 3000 to 4000). Along with bad hill climbing power the car could barely get to 60mph.
I added a bottle of Gumout as I thought I might have gotten bad gas this had no result. While trying to figure out what was wrong I also replaced the air filter.
Fast forward to Tuesday I decide to inspect the fuses in the car and under the hood (all of which looks in good condition). I started the car before i went inside and it seemed the same as it has been all week. Wednesday morning I go to leave and the car refuses to start. It tries to start but immediately quits and then shakes wildly while trying to start. I have since changed the fuel filter, replaced 5 ignition coils, and given it 5 new spark plugs. The car is still doing the exact same thing it was Wednesday morning.
This is a VW Jetta 2005 2.5 Engine

Heat blows warm at best and A/C isn't all that cold. I want to believe its a blend door issue and dive into it this weekend and fix it but there isn't a single piece of foam coming out of any of the vents. Of all the systems on the car HVAC isn't my cup of tea I don't know anything about it. What else could be the problem?I can live without A/C but the heat things must be fixed.

So my new problem is cold engine starts If it's mildly cold out like 30-40 F or 0-10C and has been sitting awhile the car won't start on the first couple of tries. It tries to start but I guess chokes/sputters out like its not getting enough gas. Warm engine it starts instantly.
I put a bottle of gumout regane fuel system cleaner in the tank hoping its a dirty fuel system seeing it feels like it chokes out on gas during the cold start. I'm about half way done that tank and was going to add another bottle on the next tank.
I'm worried about the cold winter approaching and found out issue 8001 today that the oil pan heater is ripped off with broken wires and missing cover.

I've got 149,xxx miles on my Golf TDI. Took it by a local shop for a routine oil change and since then, it's just been puking oil from the oil cooler. I took it back to the shop and the mechanic even pointed that out. Some red flags here; Timing is too shady. This happened literally the day after the oil change. He also told me that he won't use customer-supplied parts for liability reasons. Seems believable enough, but why would this part just choose to go wrong now?
This is my first time at this shop too and I've never really dealt with "bad mechanics" before but something about this isn't sitting right with me, and I'm not sure how to handle my next step properly. So what would cause an engine oil cooler to leak profusely just after an oil change?

I am having issues with our 2001 vw jetta wolfsburg edition with a AWW engine the cooling fans not working properly. I had a bad fan and replaced it and since changed the thermo fan switch and the module under the battery and still no luck. With the key off I can jump the fans via the plug for the fan switch only low speed works with the key off. with the key on i can get both speeds of the fan to operate. With the ac on the fans operate.. normal driving the fans will not operate. and the engine will overheat and fans will not go on. Any other relays or sensors that could be faulty?

I have a 2005 Golf GL trim 2L SOVC. For months now the car won't start on the first try. One must let off the key and disengage the starter then reengage. It always starts the second try and never starts the first. Once the engine runs for a few seconds, if you turn it off, then start it again, it immediately starts. It's never a problem en route. Only if you let the car sit for a while, say 8hrs or more, (when the fuel pressure dies) do I observe this "no start on first try" behavior.
I recently replaced the plugs and fuel filter and cleaned the throttle body. It's a little better now. It stumbles like it is going to start on the first try after sitting but doesn't.
I exposed the fuel pump and measured the voltage going to it. When you turn the key to "on" position, the engine computer put's voltage to the pump for about 1.5 seconds and that's it. So while you are cranking I guess it expects that 1.5 seconds of pump operation is enough. I put my fuel pressure guage on the port near the injectors, and, as I suspected, the pressure only builds to about 28lbs. On the second try it gets up to 40. Once running it's about at 45lbs.
Sounds like a firmware bug to me.I'm considering wiring in a switch that I can toggle to deliver more on time to the pump inititally - maybe 3 seconds? Is this normal?
I noticed that when I put the fuel pressure gauge on initially there was zero pressure. Is this normal?
Shouldn't a check valve keep it at pressure? Where is the check valve located? I'm also getting a P0171 code "engine too lean". I repaired a hole in the air hose going from the air pump to the throttle body - still get the code. All hoses look good.

Bought a 2003 golf gti 1.8t as kind of a project. Car had no interior no exhaust and some shifting issues. To fix the shifting issues rather than replacing solenoids I just got a rebuilt valve body. After installation the car still doesn't shift from 1st to second properly and now I don't have reverse. (It's an 09a transmission)

having some issues with my idle, when im coasting and i push in the clutch it doesnt drop down to idle like it used to it sticks at about 2000 when its dropping, also at a stop light the idle will rise up and hunt from 1700 to 2300 or so. also if im in a parking lot in second gear or so the rpms will rise and accdelerate the vehicle.

2005 1.8t gti wont start. The other day I was driving on the highway when a thin plastic type wrapping got caught in my serpentine belt. The car immediately died and I hit the gas and nothing and with no power steering i pulled over to the side.
Timing belt was done with water pump and tensioners
Spark plugs and coils are brand new
What fuel line to disconnect to test if the fuel pump works? Like I said in the title I cant hear the fuel pump priming. The engine was running 100% before this 2 techs saw it and the vw dealer i workrd at looked it over.

My problem(s) are as follows:
I recently got a 2001 VW Golf 1.8T from a buddy in the Marines. He delivered it to me at my home almost 4 hours away, as described, reportedly without any issues. I got all of the paperwork transferred so that my wife could have a solid daily driver, only to discover ...
1) The vehicle in question was apparently used by a car audio company local to him, who has done some serious screwing with the electrical system in order to incorporate (and then remove) their crap.
2) When shifting through the gears, and coming to 4th gear, you get a couple of seconds of initial acceleration, followed by deceleration and RPMs falling, which in turn leads to the speedo dropping.
3) The same thing happens in 5th gear.
4) The only option is to downshift to a lower gear, which she did, and was apparently cruising along at 60 mph in 2nd gear, as 3rd gear was behaving the same way as 4th/5th upon downshifting. I'm not a mechanic by any means, but I'm pretty sure this is a BAD thing .

Happen a few times already. My RCF had problem starting at night only after parking for a couple of hours. During the day the car start fine and never once have starting issue. The problem is when I press the start button the car will try to start then die immediately. Second and third push will be required before the car would start. Is this a problem with fuel pump? I don't hear any noise issue from the fuel pump that others have reported. I notice that this starting problem only happen at a particular hotel that I play tennis at after work. The hotel is at sea level our day time temp is mid to high 80's. At night it is low 80's. Our humidity is quite high at 80%+.. Going to have the car checked on next service.

If I get in my car to hard or even when I'm in the car and rock back and forth while standing still it sounds like the springs squeak, kind of like a spring bed when getting it on. I don't hear it when I'm driving though.

I own a automatic 2002 Mazda Protege with about 167,000 miles on it. The other day I was at a stop light and when I accelerated it felt like the car was taking longer than normal to get into gear. I am scared that it may be a transmission problem.

I have a 2.0. Custom gt28 turbo project. Been up and running for awhile now. Took it on a 4 hr trip home and drove it back.
All of a sudden after the holidays it started to overheat and I had no heat. It will not overheat when idling. I replaced the thermostat recently. Lower hose gets warm when it opens. I replaced the green top sensor. I have done a wire tuck etc and I am running a closed coolant system. I believe I have gotten the air out of the system.
It will idle all day at 190. But as soon as I drive and accelerate hard or go over 50 mph it overheats and will not cool off unless I pull over and turn the car off. It will steam as if it's losing coolant somewhere but I think it's at the cap (too much pressure?).
I am thinking water pump but I am not sure. I got the car with 124k miles I'm at 127000. I was told timing was done at 90 could the pump be failing already? Also when it overheats I get a cel for misfire is that normal?
