Question about 2000 Volkswagen Jetta TDI

4 Answers

TDI loss of power

On way to work noticed significant loss of power w/ no noticeable event preceeding. Hard to maintain 60mph on minor inclines and drop down to 50mph on moderates. Revs up to 3100rpm on moderate inclines w/ little acceleration response. Have I lost my turbo or dropped a cylinder or something like that?

Not mechanically inclined.

If all checks out good on the turbo, could be Cat. Converter. Does the car have a lot of miles? Are you getting a Code"engine light"? if so, take to an auto parts place to read code, should do it for free.

Check the hose on the intercooler and around the turbo, check for split on turbo and the intercooler hose not too soft as they can collaps while driving

    it sounds as if your car had a problem before with either the turbo and or the intercooler those are easy to check take it to an auto parts place like autozone and they will hook up the diagnostic check tool for free but from the sound of all that smoke it most likely had a cracked head before and someone welded it seen it done it just never lasts forever that will show up if you check your oil see if there are water droplets on the stick then its either a cracked head blown head gasket etc. if it is this type of repair let a proffesional do it as there are so many things that can go wrong

Major loss of power suddenly is probably limp mode. This is a very common issue with high mileage TDIs. The ECU will pull boost to "protect" the engine from what it thinks is a potentially damaging situation. The most common cause for this is degraded vacuum lines, a faulty N75 valve, or stuck VNT turbo actuator.

Since this happened suddenly, I'd suspect vacuum lines or N75 valve. Stuck actuator is usually progressive and not sudden. Secondly, if it is limp mode, you should have a check engine light. The codes that will reveal can help pinpoint the issue.

I'm not going to tell you this will be cheap and easy to fix, but it really is a minor issue. If you're not mechanically inclined, it's time to get this to a trusted TDI mechanic in your area. Check out this google doc to find a mechanic close to you:

Could a short in the plug that goes into an ignition coil for cylinder number 4 or 6 cause a loss of power, a loss of pick up, and can cause a car to completely shut down?


Please charge your battery with a charger before you fry your charging system. It may need to be replaced. It may be too late for your charging system. When you drain the battery dead, there is still chemical energy left in the cells. If power draw is stopped, the battery will seem to charge itself and work again. In doing so, a part of the capacity is sacrificed forever. If the battery is drained empty more than a couple of times, it's time for a new battery.

To the car, a dead battery is an overload. Some vehicles are designed not to try to fully charge a dead battery. Most vehicles will burn the charging system up trying to do so. Same idea, if this happens much you will need a new alternator and maybe more parts.

I would definitely have the car serviced by a pro shop, with veteran mechanics. Discuss your concerns with the ignition and charging systems, and tell the tech about your power loss event. Symptoms such as this are better fixed before murphy's law kicks in and you are left stranded on the road somewhere. The repairs cost less before everything is destroyed as well.

Loss of power any incline i know that to much oil was put in on last oil change driven about 500 miles before i noticed and drained and put proper amount in. could the catalatic converter be causing t


Filling the engine oil above the maximum fill mark on the dipstick can and will cause damage to the catalytic converter. If you have a check engine light on scan and look for a code that indicates a problem with the catalyst. If there is a code indicating a problem with the catalyst this is your catalytic converter. You can get an aftermarket converter from about any parts store for around $200 but it will probably only last about a year. I recommend a VW Genuine converter and they are about $500 but they last much longer than the cheaper aftermarket converters. Before you run out and buy a converter, make sure that this is the problem before you spend a lot of money only to have the same problem. 1 way to verify it is to remove the converter and install a section of pipe where the converter was and see if you still have a power loss. I do not recommend driving the car this way for a long period, just long enough to test it and verify it or further damage may result. Hope this helps.

Lifter tapping


The tappet noise usually will get louder and louder as it wears. A totally collapsed lifter will definitely be noticeable by loss of power to that cylinder, misfiring, and excessive noise. But then again your current lifter noise could be possibly maintained for years to come by regular and consistent oil changes.

Tranny is very rough and jerky around 50-60mph and especialy on inclines. Fluid and filter recently changed


This could be a misfire in the engine, get it scanned for any codes and have the shop look at mode 6 to check for any misfire events.

2002 vw jetta tdi - problem with rpm gauge?


Hi, Did you notice the motor actually reving higher when the tachometer was reading a higher rpm.. If it was it could be your transmission slipping.. Set your cruise control and listen to your motor while the tachometer starts moving erratically.. Good Luck
