Is anyone familiar with diesel VW's?

[Holladay]

I have a 2002 Golf TDI that occasionally hic ups while driving. Loses power for a short period of time, then goes away.

My mechanic thinks there is an air leak in the fuel system. He beliefs that in 2004 VW put fuel pumps in the tank. He knows mine doesn't thus the fuel injector is the pump. He acknowledges that he is not an expert on VW's.

It will cost $2000 to replace. Crud!

Can we put in a 2004 pump in? The tank is under the back seat.

My wife loves the car. We don't really want to put $2000 into an 2002 car with 160k miles.

Thoughts/ideas?

Someone unban Extorter so he can go another round with Sauto.

I hope this helps.

Find a friend to help you replace the fuel pump. You can buy a fuel pump for under a $100

Thanks.

Forwarding that article to my mechanic.

My mechanic stated that the 2002 didn't have a fuel pump. VW started that in 2004.

My son and I replaced the in-tank fuel pump in my SUV. Can't speak to how easy it would be in a VW, but it took us only a couple hours. I'm no mechanic, but this was pretty easy stuff.

An update:

Although the TDI's in 2002 didn't come with a fuel pump in the tank, there is a spot for one because they made so many versions of the Golf. If it was a gasoline Golf, there would be a fuel pump. There is an access door to the tank and a spot for a fuel pump.

That would be a nice easy and MUCH cheaper solution.

They have a Bosch VE VP 37 fuel injection pump, that’s what they came with from the factory anyway.

You mean the Injector pump not the injector? Does it start right up or is it a battle to get and keep running?

In 2004 they installed a pump in trunk as a pre or primer pump using the same injection pump. Haven't dealt with VWs much but it sounds like many a wife after 10 years being married... Just doesn't suck like it should:D:D:D:D:D

I am thinking reseal and see if it fixes it. $30-40 plus labor.

Yes pump not injector...as far as I umderstand.

Starts fine. 5 min into the ride...hic ups with low power. After a bit, it does fine. Then happens again.

It has to be a Gremlin:) Hate those beasts.

Yes, that is what we are looking at. Putting a "fuel pump" thru the trunk access panel into the tank. If that was what you were thinking about.

I drive a 2013 Golf TDI.

I don’t really have anything else to add. 160,000 is really barely getting warmed up though.

Man fuel issues in diesels are a pain in the cock.

The diesels I run are way different than those little TDIs. The first thing I’d do for any potential fuel problem is change the fuel filter. It’s the cheapest and most likely to cause restriction.

If it loses pressure on the fuel rail or an injector is bad it should throw a code. Definitely check those. I’d think if restriction was coming from the fuel filter it would have a code for that too.

If air is getting in, more than likely diesel is getting out. Look for a fuel leak. About the only exception would be in the intake side of the injection pump. Potentially a cracked fuel line or fouled seal could cause you to suck air. It’s possible but typically failures are caused on the pressure side - fuel lines and injectors.

Visual inspection then run codes is my advice.

Why, if you had an air leak, it would have air in lines, would run shitty, not want to start.

that was some of the best reading on CP.

that was some of the best reading on CP.

But the software says the standard time for this job is 4 hours, so I should just charge the customer for 8! Don't you get it Sauto?!?!?

[Dayze]

for the uninitiated, the Extoter / Sauto exchange thread was basically this; Sauto being Peyton, of course.

Add a quart of automatic transmission fluid to the fuel tank and then fill it up with diesel fuel.
Your injection pump is having lubricity problems.
Then start adding Cetane to your fuel

I was gonna buy a TDI until I realized it puts out 6 times as much pollution as gas. 6X!
