Question about 2003 Volkswagen Jetta TDI

1 Answer

Engine light has been on, despite all repairs made.


My engine light has been on since last November. I have taken it into the shop three times, each time they replace something (coolant the first time, ECT sensor the second and third time) but the light will only stay off for a day or so. I bought an engine tester and found out it is coding that my engine is running cold. The only performance issue I have experience since this has happened is on cold days (Texas cold, in the 30’s) It will not start right away. I have to start is a second time to get it to stay on. What can I do to fix this and is it damaging my car?

30 is not a low enough temp to worry about too much, but I had similar problem with two sensors, finally got the third one installed and it worked fine try getting the sensor from a different part of the country, I am sure they make them batches that do go bad and us consumers are the testers for their low quality controls, good luck Fareed

If you go to Autozone or Oreillys they will scan the car for free. You also need to have the old trouble codes erased to see if repairs are effective.

What I have a problem with is the car is capable of showing several defects at once. It is unusual for several items to be bad before 1 item shows up. Each sensor should have coded separately and earlier. Also true for the CAT converter.

Engine shaking after timing belt replaced


No repair should only last three weeks...don't touch anything and have the shop that did the work come and get it. I have lots of ideas but it will need to be checked over to verify them. Rather than comment on the "maybe" of this, have them check it out. Any reputable shop will be more than willing to do what's needed...Bad jobs ruin that reputation!

Alternator keeps going bad - three so far. Battery light flickering off/on now.


You have probably been getting 'rebuilt' units which is not bad in itself but if the rebuilder received a batch of bad diodes they may have these failures until they are exhausted.
But, buddy, you ain't broke my record yet; a lousy Saturn (LAST GM I will own!) bought new, ate SIX (6) alternators in 57,600 miles. That wasn't the worst problem; it ate the auto tranny at 31,000 and dropped a rod cap at the above final mileage.

Check engine light,engine miss,loss of kompressor power


might have a vacuum leak. 2005 c class 230 kompressors have issues with the engine vent hoses under the intake manifold deteriorating and coming completely apart. This will cause mixture adaptations to max out and can cause missfires. Usually it sets a check engine light when it gets bad enough. There is a factory recall to replace these hoses, so check with mbz to see if your car has an open recall

the easiest solution is to have a dianostic test done at a shop you trust. it will tell you why the light came on. usually just a sensor will need to be replaced. but the test can be exspensive, $75-$150.
