Hi,

I have a 2001.5 Variant V6GLX 4Motion with about 65,000 miles on it.

THE PROBLEM

I went to start the car the other day and it took a few seconds of holding the key down before it started. For a second I thought the battery was dying or there was a problem with the starter. Once i got it started it ran fine and started again without a problem. About a day or two later I started the car again without a problem but it idled very rough for a second or two. A day or so after that the check engine light came on. We brought it to the dealer and they are saying that I need fuel injection service and need to replace the Engine Coolant Temp Sensor and that I might also need to replace the secondary air pump. They want to charge me $421.75 for the fuel injection service and the Engine Coolant Temp sensor. They also said that there was a kinked vacum hose that they had to straighten before they could run the diagnostic. Are they full of crap?


Thanks
Mark

I had the same problem, yes i believe the throttle body is dirty so that is why it is rough to start and to idle so they are right on that, second the engine coolant temp sensor could be going but if it does go bad you will prob not have the car be starting. Then the Secondary air injection pump will tell you that it is going bad when you start your car you will hear a whining. IT is not needed to replace unless you plan on passing smog soon. you need it to pass smog. and my car would not start b/c the injection system is dirty. and i am picking my car up from the dealer in an hour. It is only costing me 300 for the injection cleaning.

You are getting ripped off with the fuel injection service, but everything else sounds right.

The coolant temp sensor is the most likely cause for your starting problems.

The secondary air pump is likely the cause for your CEL.

I had the same symptoms and they went away as soon as I changed the Coolant Temp Sensor.

Sensor can be had for around $10.00 (or 30 if it's the Blue one) and I did the replace myself in about 1 hour which included figuring out the location and getting my big hands in to replace the thing. It should take the dealer less than 1/2 hour.

I would get the sensor replace first and then see if the symptoms go away.

full of crap... if you dont have warranty and not too good with cars, take it to some local indy mechanic (preferably vw/audi specialist) before you start replacing parts, have the fault codes scanned. if your temp gauge works then i would say your temp sensor is fine, if it doesnt move or moves weirdly than its 100% faulty temp sensor...

that 30 dollar blue sensor in reality cost 10 to 15 dollars, plus 1 dollar with change for o ring if yours is bad and most likely it will be bad....

The blue sensor cost me $31.95 + 0.59 for the O-Ring + 0.77 for the clip in November. You can get the Blue ones at ECS for 22.95. For me it was cheaper and qucker to buy one from a local shop rather than pay shipping, brokerage fees and maybe duty on the ECS one. If you can get it cheaper that's great. Where?
