Hey, you TDI guys!
 
I know this isn't about Benz's, but I need a little edumacation. I could think of no where better that to ask you guys here that also own or have owned a VW TDI.

I have been looking around on the 'net at some Jetta & Passat TDI's, mostly in the 1998 to 2001 year models. I had a '86 model Golf 2-dr. 5-spd. with a NA engine many years ago & loved it; but I know nothing about the new generation TDI's. So I have a few questions if you will permit me:

My indie tells me that VW's in general suffer from electrical problems, specifically a "box" over the battery that is not well weatherproofed & therefore suffers from water intrusion, causing many problems. Is this true & is there a fix for it?

He also tells me that the auto trans in VW's burn out easily. He says there is no fix for it, but I was wondering if an externnal cooler would help this situation out.

I hear that these are great little cars, but would appreciate anyone's experience with problems owning one.

Many thanks in advance! Mods, please leave this in the Diesel Section.

Just do not buy the automatic version especially during the years you mention. To add to the general mysery the last ratio in the automatic is punitive in nature compared to the manual transmission.

Volkswagon still has a following. Personally I have written the newer ones off the aquisition list as they get worse as they get newer. I still would buy a 1999 1/2 to 2002 tdi with low milage for some of the benifits if I just had to buy one.

The 1985 and 1986 where the pinacle of practicallity for them in my opinion. Quality perhaps as well. I have owned a whack of them over the years. Including a new 2000 tdi. Unfortunatly the company has just fallen off my radar basically. Other car producers are doing much better in my experience. I also have some issues with the premium used newer volks diesels seem to bring.

I own a 2004 TDI Jetta wagon, and I worked at a VW diesel shop for a while. This is how I look a VW. They made affordable, economical cars. Nothing lasts as long on the VW's when compared to the MB's. But the parts cost half as much and are often half the size. The old ones are tin cans on wheels. I'd never want to get in an accident in a Rabbit.
VW's in general due suffer from electrical problems, some electrical issues due to water leaks, others not. The fuse block on the older cars is right under where the windshield likes to leak. You do the math. The auto trans are much more prone to failure than the manuals. The autos also eat up some mpg's. The TDI injection pumps are prone to leaking. The pumps can be resealed. I did a few at the shop. The most dangerous leak is the input shaft seal on the front. When I leaks it drips on the timing belt. If you're running biodiesel it can eat up the belt if it's bad enough. Which means a lost timing belt and a whole lot of other issues in a zero clearance engine.

I've owned my TDI for a little over a year now and it has 133k miles on it. I've had to chage the alternator pulley and serp belt tensioner, and thats it. Though I do think I've got either a worn wheel bearing or a axle going out. The POs took care of it, and had no issues, just routine maintanence.

The large strip fuses on top of the battery for the radiator fans, cabin circuits, alternator, and some other things carry a lot of current. If the connections corrode resistance builds, they get hot, and melt the plastic.

FWIW I'm at 265,000 miles and 11 years on mine. I have not touched them.

The automatics are a weak point. The solenoids in the valve body wear out, leaking pressure, so the trans stops "fully" shifting, gets hot, and breaks various expensive parts. The only good option for a failed unit is a VW reman.

Thanks for the link,Compu85. If that doesn 't scare the ***** out of someone, I don't know what will. And I can't use a manual because of my cancerous shoulder, so it would have to be an auto.

Too bad, too, since I found this: http://wilmington.craigslist.org/cto/2508028751.html

compu_85 07-26-2011 06:07 PM

The auto isn't terrible, just plan on repairing it. I want to get an auto myself, I spend at least 2 hours a day in traffic.

dagObx 07-26-2011 07:19 PM

I'm still reading that link. Some there say it's a overheating problem, as well as problems with bad parts. I wonder if an external cooler would ease the problem somewhat...

I hate it, too, since I would really like to have one of these.

We got the '06 Jetta TDI from the dealer, showing 40 miles. It now shows 86K.

This car has had no warranty work done. Never needed it. The Mexicans and Poles did something right. Ours is a manual. I did not consider getting a DSG.

Oil changes are expensive for something that only takes 4 quarts. Timing belt job was expensive (partly due to required special tools) but otherwise routine.

Dubyagee 07-26-2011 10:33 PM

Im looking at an 11 Jetta TDI. Keeping an eye on this thread.

compu_85 07-26-2011 11:36 PM

The Common Rail is a different beast than the older cars. Many many more parts. There's two throttles, two EGRs, and the glow plugs are also cylinder pressure sensors for example :eek:

drgreenthumb 07-27-2011 12:17 AM

I have a 05 Passat that was a one owner, dealer maintained vehicle. It had 71K on the clock when I bought it and now has 82K. I have had to do some maintenance but nothing major.

The auto trans seems to be fine. I will be changing the trans fluid soon. VW claims it has lifetime fluid but I am not buying it.

The engine is a PD type where the cam activates a pump/injector unit through a rocker arm. oil selection is criticle to keep the cam healthy. The engine has a fatal flaw. The balance shaft is driven by a chain on the US model. Everywhere else in the world got a gear driven BSM. The chain tensioner can fail and throw bits of metal into the drive belt. This is bad. There seems to be a debate on just how wide spread the issue is. Some on the TDI forum argue the BSM HAS to be changed, while others say it isn't really a problem.

It is a nice vehicle....by far the best VW I have ever owned. It is at the end of the day still a VW. Little things break and IMO a 6 yo car should not have brittle plastic already. It is a small peppy car compared to the Merc, but not even close on build quality. I commute 120 miles/day and the VW is a good fit for that and serves it's purpose well.

I had a 99 MK3 auto, it was on its 3rd trans at 85k miles.

I have a 1990 1.6L NA Diesel 5speed. It won't go down the road like a benz... ever. But they do do WAY better on fuel.

What was the reason for the failures? I have never had a auto VW until now. I have put over 200K miles on the standard transmissions several times.

barry123400 07-27-2011 01:49 PM

There is a refference to the automatic transmissions on the volkwagons posted earlier on this thread. I thought the passat used a different and better automatic transmission. May be wrong about that.

It is not only the failure rate of volkswagon automatic transmissions that is troubling. It is also the horrific cost of correcting the situation. Some gas cars are so much better on fuel now in concert with the tdi getting progressivly less fuel milage since introduction.

I no longer see as strong an upside of buying a new one. Volkswagon does produce models that get really good fuel milage. They are not comming to north america though.

Also be careful of build quality. There are serious issues at the mexican factory now I hear. The latest ones seem to have dropped the twelve year rust perforation warranty as well. Have they discontinued their excellent factory rust proofing?It was very expensive to use and really seemed to work well. If it has been discontinued I can see no good reason to consider a new one at all.

Also in reflection if you own or aquire a 19991/2 or newer get a skid pan. All too many people have smashed the oil pans etc. This car has inadaquate ground clearance.

I now almost see these as cult cars . Practacality or reliability is not their strength. Customer service with the brand from the actual company is the worse I ever saw. It may be improved now for all I know.

Basically what I am obviously implying is I once was a fan of the product. Certainly am no longer.

dagObx 07-27-2011 04:02 PM

I read most of the link than Compu 85 posted & I think it should be mandatory reading for anyone contemplating the purchase of a TDI.

It seems that the most transmission failures were related to the 01A automatic transmission, which according to the link, were installed on the 1998 - 2001 Jettas (possibly other models as well). The link states that it is not a matter of if, but when the trans will go out - due to shoddy parts. Apparently VW used some parts with substandard steel in them. Mentioned chunks of metal in the pan, with little or no warning of failure. Replacement costs ~ $4,500 - there is no "fix". It also stresses the importance of keeping the trans fluid topped off to prevent overheating. That prompted my question about an external cooler, but that would do nothing for faulty parts. VW is not repairing these faulty transmissions, only replacing them. Doesn't say a lot about VW, especially at $4.500 a pop.

I have tried a 5-spd. VW tranny in a local Jetta, but I'm not sure I would be able to handle it every day with my bad shoulder. If I could find a way to shift it with my wrist instead of using my whole arm I'd be in business. I just can't take much movement in my shoulder - even under the influence of Vicoden.

Thanks guys. I'll keep on looking & thinking. If Farm Bureau totals my '87 124 diesel, I'll have to seriously consider the VW. Although I love my Benz & know the VW will never be its equal, I live a long way from anything (65 miles to the nearest WalMart) & my continued trips to the veteran's hospital in Durham (534 mile round trip) may dictate the change.

Matt L 07-27-2011 08:37 PM

Ours motors along at 75-80 MPH delivering better than 40 MPG. Hard to beat that for a commuter. Except for the comfort factor; the Benz is silky smooth going down the road at that speed, the Jetta, well, not so much.

ashedd 07-27-2011 08:42 PM

I can't comment on the OP's questions... just wanted to add my two cents.

I had an '85 golf diesel that I liked very much. It was sorta a clown car for me, since I am 6'7".... my friends would laugh at me. But despite low compression it still got 45 mpg. I was always concerned about how well it would perform in an accident. I still liked it tho. It was my first diesel.

rs899 07-28-2011 06:43 AM

My current daily driver is a '91 Jetta IDI that gets close to 50 mpg. It's suits my commute perfectly well and is actually a very well built car (would have been even better without all the extra plastic they added to get the "big bumpers" look). I had been running my Rabbit pickup until some crazy Korean chick rearended me (lightly) at a light and I realized how vulnerable that heap was (the rigid bed ends right at my a$$ and it's a unibody-ouch- still drive it, but it's semi retired). I feel a lot safer in the Jetta as there's a lot of crumple area behind me and I can control things playing out in front of me.

Anyway, the Jetta, with the proper gearbox (this is a code ACH, they came with a lousy AWY one) is more than a match speedwise for a 240D stick. It's feels very competent up close to 70, whereas I would never think of thrashing a 240D like that. Probably a lot like a 190D stick, but I have never driven one.

Of course, this doesn't help the OP, as they didn't come in automatics, but for the rest of you luddites...

Actually it's the 01M that is the dreaded transmission to watch out for. Used in the 99.5-2003 yeras of Golf, Jetta, and Passat I believe. My 2002 VW Jetta TDI had the 01M that failed, and it got replaced(by me) with a 5-speed with a taller 5th gear. My MPG's went from 45 with the auto to 53 plus with the manual! For me my TDI has been very maintenance intensive, and there are some "gotchas" that have to be tended to. Overall now that I have most issues straightened out with mine I love it. Highest city driving MPG I have gotten are 56 in town, and lowest so far with the 5-speed has been 53 in town. FWIW

I am in the process of looking for a 1999 E300D for my family, and once I have it I plan on implementing a little "out of the box" solutions to increase it's fuel mileage similar to the ones I use on my TDI.

Just sold my 1996 Passat TDI with 274k miles cause i found this sweet 1982 240d. I still own a 2001 Beetle TDI 5-speed & 2006 Jetta TDI DSG automatic.
They get great mileage! but agree with the others that the fit and finish of these VW's are not what our Mercedes are. I enjoy them. And will buy another one simply because i wanna hot-rod one and still get 40mpg :-)
The 06 gets about 38mpg with the new type automatic (not the problematic one's of 1999-2003ish). The Beetle gets 48mpg and as high as 58 when driven painfully slow with no AC. The Passat avg was 46mpg with 49.8mpg as my highest tank. And the 96-97 Passats had the largest tanks. I'd average 900 miles per tank. I loved that! I hate the wax feeling coating they put on the interior plastic parts that makes them look like crap! I did have to put a camshaft into the 06 but that is a known issue and i paid a very discounted price buying the car due to this issue. Had two power window issues which was broken wires. And OH YEA lets not for get the foam coming out of the vents!!! I sold mine before the repair was done but they say the foam is covering the blend door for the ac/heat in the dash. You have to take apart the whole dash for this repair!! Can't remember if you loose your heat or AC or both due to this!!??!! The ones i had did not have any more mechanical issues than the Honda's or Toyota's from my past.
But over all I like them if they are 5-speed!
Oh yea the opinion is N E V E R take it to the stealership...eeerrrrr dealership!!! (at least from what i've heard) There are plenty of TDI specific repair shops who will KNOW how to repair or maintain your older TDI's and know of specific issues with each model. And the TDIclub.com website is very informative like Peachparts.com on the forums!
Good luck!

have an automatic 2001 golf tdi. hate the transmission. weak, lousy ratios, sloppy as hell now. get a manual!
