#21 of 2484 Timing Belt and Oil by moparbad Feb 12, 2002 (8:41 am)
For more info. on TDI in general and in detail try www.tdiclub.com. Timing belt can be found here http://www.vwparts.com/partlist.cfm?expmake=1&getpart=162321&subcategory=185#part162321 and here http://www.dieselgeek.com/golf_iv_main.htm . I found out about the timing belt at tdiclub, the dealers sadly had incorrect info.. The number for the engine should be on sticker on top of timing belt cover and should read ALH XXX,XXX. The tensioner does not need to be changed every time if you are using the old interval of 40K or 60K miles but MUST be changed to the new style tensioner when using the new 80K belt. I highly recommend using diesel specific synthetic oil in the TDI. Recomended oils are: Mobil Delvac 1, 5w40 (full synthetic, a reformulated version of Mobil 1 which is intended for diesel engines) Chevron Delo 400, 5w40 (full synthetic version) Shell Rotella T (full synthetic version, not to be confused with Rotella SB synthetic blend or regular Rotella T non-synthetic) Amsoil Series 3000, 5w30 (full synthetic, CH-4 rated) Amsoil High Performance, 10w40 (full synthetic, CH-4 rated) Amsoil semi-synthetic 15w40 (CH-4 rated and high quality, but almost as expensive as the full synthetic, and higher viscosity at low temperatures) Redline, synthetic version (make sure you get the type meant for diesel engines, with the CG-4 or CH-4 rating). Oil in diesel engines needs to be able to suspend the soot that diesel motor creates and I am not going to trust a non-diesel specific oil.

Do I have to take the top engine cover off to get to the timing belt cover? My car is just now going out of warranty and I'm not real familiar with everything under the hood yet. I just want to look and see which engine number I have. By the way, thanks for all the great info. I am currently using the Mobil Delvac 1 in my car. I plan on doing an oil analysis this time around...   Thanks again
#23 of 2484 Upsolute Chip? by bluewolf Feb 20, 2002 (3:28 pm)
Anybody have experience with the TDI chip from Upsolute? My TDI with AT is beautiful on the highway, but I'm thinking another 25HP and 40 ft-lbs of torque would be a blast. The price is very fair IMO at only $325.

did the chip void your warranty? I'm thinking of this but will not if warranty is voided. Also, who performs the work?

natescape!
#28 of 2484 Chipping and TDI by moparbad Feb 22, 2002 (7:48 am)
The Upsolute chip or any other chip that alters the ecu program does have the effect of voiding your warranty on any component that could be affected by the changes the chip causes. This is the reality if you have a component failure and VWoA decides to play hardball. Also a reality is that the Upsolute chip is proven in the TDI and it is not going to cause any component failures. And as natescape stated the chip is difficult to detect and some dealers are friendly to chipped cars. So the bottom line is that chipping your car will not affect reliability, will give you increased performance without decreasing mileage, is the most cost effective way to increase performance on the TDI, and does involve a very small amount of risk should you happen to have a blown engine, turbo, injection pump or etc and VW uses the chip as a scapegoat.
#29 of 2484 Morparbad.... by jabilda Feb 22, 2002 (11:00 am)
I have heard this before - why doesn't VW offer the chipped-up version in the States? Is there some type of EPA limit they violate by chipping the car? (I.e. - the chip sounds 'too good to be true'.) I have read this along these threads and appreciate all of the info. I'm just a little leary about it. Are there any horror stories w/ using the chip and / or any difference in maintenance from adding the chip?   Thanks, again, I appreciate the info.
#30 of 2484 Chipping re jabilda by moparbad Feb 22, 2002 (11:37 am)
VW Germany offers many, many choices in Europe than are denied to US buyers. Who knows why? VWoA certainly is not offering any info.. The Upsolute chip is very popular in the TDI so it has a history. Other than a small increase in soot and sizable increase in power, it requires no difference in maintenance, and there really are NO horror stories. Wait, there is one thing, if you have a manual transmission and you chip the car you will likely experience some clutch slippage. The increase in torque and HP does shorten the life of the clutch. A clutch upgrade is available http://www.dieselgeek.com/clutches_index.htm . Some people do not experience clutch slippage, it really depends on how hard you drive your car. I do not have my TDI chipped, but do have plans to do so some time in the future.
