Injector Pump Problems
I have a '98 Jetta TDI, 68500 miles.
Has anyone experienced problems with the injector pump? My dealer is telling me it needs replaced at $3500!! This seems rather high to me. Shouldn't this be covered by the warranty?

Re: Injector Pump Problems
It is HIGHLY unlikely that the pump is bad. All kinds of other things can be wrong which make the ECU think the pump is bad even when it isn't. The dealer service goons just go by what the computer tells them even when common sense dictates that the computer is wrong.

What are the symptoms?

Hell! You can buy a Complete motor except Computer from Adirondack Auto Brokers for 3295.00! 3500.00 for just the Pump?

Re: Injector Pump Problems
Ok depending on where you live and subject to the kind of fuel you've been using, it is not unusual to have and inj pump fail... failure is usually the result of poorfuel not providing the lubricity that the pump needs... hence a lubricity additive is highly recommended, there have been numerous failures up here where it gets really cold... and the feedstock ins't as good as it used to be... yeah sulfur....

but everyone is right, an ijection pump is about 1000.00, and a local diesel shop sould be able to service yours before you give those dealer thieves any of you sheckels

Re: Injector Pump Problems
I don't know whether the injector pump is covered under the powertrain warranty or not. I suspect not. would be a better bet for a brand new pump. The dealer will rape you on that deal. Even better still: Locate a Bosch factory service center and have them rebuild your pump.

All this is assuming the pump is actually bad. It's possible, but unlikely. What are the symptoms? These pumps are essentially the same as the ones on Dodge Cummins turbodiesels. A Cummins diesel repair facility might be able to diagnose it more effectively, once they get over laughing. (They're used to BIG diesels!)

Re: Injector Pump Problems
The problem/symptoms are as follows:
I started the car and it rev-ed up to about 3000 without my touching the pedal, then it returned to normal idle. Upon driving it lacked acceleration, it didn't pull beyond 2000 rpm's. Up until that point I had not had this problem. I live in Ohio, so it does get cold here, but on this day it wasn't too bad. The dealer I took it to (different from my regular dealer), indicated that the timing belt had never been changed! Nor had any of the filters! According to this dealer, none of the schedule maintenance other than oil and oil filter change had been completed!! I had noticed a marker drop in fuel economy on my fill-up before the above problem.

Re: Injector Pump Problems
All you need to do is take your pump to a authroized Bosch dealer they can run there own tests on the pump to find out what is wrong with it. Heck it would be cheeper to have your pump rebuilt or at least repaired rather then letting the dealer bend you over contact Bosch and Get you pump Looked at. I have a friend who owns a company who is a authroized Bosch, Lucas Etc, dealer and i have had a pump rebult on my 1985 vw diesel and it is a heck of a operation testing and rebuilding about 10,000 parts in these pumps pretty neat operation.

Do you get a check engine light?

Re: Injector Pump Problems
Nope. The dealer said "the diagnostics said the injector pump was bad".

Re: Injector Pump Problems
My diesel injection pump was replaced under warranty with 16,000 miles on my 99.5 jetta.

My vag-com said code 17656 (p1248).
This could have been
1. Cold start injector bad.
2. Needle lift sensor (inj #3) bad.
3. plugged fuel filter
4. No fuel da
I checed the above and so did the dealer.
Dealer replaced the pump with 038-130-107DX
This was a remanufactured pump (ie the x).
I said I expected new. Read your warranty. It state fix or replace. They replaced with a fixed one. Anyway the rebuilt from a dealer is 1500. The new ones are 3500 (from a dealer). Don't think they won't try to charge 3500 dollar for a 1500 rebuilt.

The new warranty still covers my bebuilt for 100,000 miles.

The pump solved the problem...Perhaps it was part of the pump electronics because earlier my computer was replaced on this car.

Re: Injector Pump Problems
Where is the car, at home?

Did you make sure all the electronic connections to the pump are good-maybe take off the connectors and put them back on again.

Where do you live? Maybe there's a Fred's member nearby with a code reader.

Re: Injector Pump Problems
Someone gave me some good advice some time back:
"If you ever have a problem with a diesel fuel system on your car, particularly the injection pump itself, the very LAST place to take it to or seek advice from is the car dealership." They are almost invariably totally clueless on diesel matters, and will end up fleecing you for their BS & incompetence.

As the guys above have said, take it to a diesel specialist, usually the nearest Bosch/Lucas or whatever, Service Centre.

Re: Injector Pump Problems
Karl: Car is still at dealer. I'm in Ohio.
I have done any work on the car as I have no experience dealing with diesel motors. I'm beginning to see some education is in order.

Richard: This is the first mechanical problem I've had with the car. I took it in to the dealer because I didn't know their level of ignorance until now. Unfortunately I didn't find this site until after I began searching for ammunition for when try to lay a line of b.s. on me. I will be going to a diesel specialist.

Re: Injector Pump Problems
Our local BOSCH authorized diesel engine service shop just so happens to be the Mercedes Benz dealer in town. MB used all BOSCH diesel injection pumps here in USA, so that is an excellent place to find a real live trained diesel engine mechanic. BOSCH USA's website also has a state by state listing of every authorized shop too.
