Replying to: shipo (Mar 30, 2009 7:10 pm) Let me be clear - do not any oil-treatment on a normal basis and instead use only real GERMAN MADE OIL that VW uses in German built vehicles. HOWEVER: The original appender asked for a LOW BUDGET way to alleveate a problem with oil-pressure sensor alerting when engine under load. My response assumed that they would prefer not to order oil from Germany nor rebuild engine. With a high-milage engine and the other option is to tear-apart engine.... using STP Oil Treatment is a GREAT alternative in my book!

The fact is that unless the OP has used 502.00 oil since very early on in the life of that engine, and changed it at least every 5,000 miles, the engine is probably heavily sludged. If that's the case, then one of the first indicators that the sludge is in there is when the oil pressure light starts blinking. The thing is, the blinking light is typically because the oil pickup screen has become clogged with sludge. If that's the case, then thickening the oil with STP will only hasten the demise of the engine as it will be even more reluctant to make its way through the pickup screen. So, to the OP: The first thing you should check is the oil pressure sensors, however, to do this you'll probably need to take the car to a mechanic familiar with the 1.8T and have him put a mechanical pressure gauge of known accuracy on the engine. If the pressures look good then you probably have a sensor or two that is in failure mode (this is a relatively rare but not unknown problem). If the pressure is genuinely low, the next thing the person on a budget might want to consider is pulling the oil pan (a job I haven't done on your particular car but have heard that it is pretty easy as there aren't too many obstructing components below the engine) and inspect the oil pickup screen. If it's clogged, pull it and either figure out how to clean it with some sort of a solvent, or buy a new one. Long story short, whatever you decide to do, do NOT put STP in your engine. Best regards, Shipo

Replying to: shipo (Apr 01, 2009 11:46 am) However, the drain period you suggest of 5000 miles is, I believe, merely a device used in the U.S. market to generate income for Service Departments. Same engine, same oil spec here in Europe gets 10000 mile oil changes, (IIRC), as a VW recommendation in the handbook and current editions are 20k. Even the later TDi engines now go for 20k miles between changes - using the correct spec oil. Low-miles between oil changes seems to be a feature of the U.S. market which Europe would never tolerate. My 2004 1.9 TDi 130bhp had an interval of 10k miles and that is now 20k miles on the later ones. My Volvo S60 with the D5 engine runs 18k between changes under full warranty, sames as the petrol-engined variants. The oils and the engines are certainly up to it but the Service Dept doesn't get as much profit. I cannot imagine a 1.8T engine sludging up - using the correct spec oil, anyway. I can't remember when 5k oil changes ceased in Europe; it's so long ago, (except, perhaps, for some very exotic stuff but certainly no "production" cars). I have related elsewhere a local taxi guy running 410k miles in 4 years without any problems other than tyres, a clutch and service items. That was a 1.9 TDi engine running on 10k miles oil changes and the car is still in daily use by his wife. As for STP in modern engines - no thank you. With a TDi engine it might just invalidate the warranty as you have contaminated the original oil spec. Just some thoughts from the U.K.

Replying to: shipo (Apr 03, 2009 10:17 am) While this might seem like a small thing, The TDI's "oil use" has been app 8oz per 10,000 miles or app 1/2 qt (16 oz) per 20,000 to 25,000 miles OCI. Incidently the oil used since oem fill and recommended oil change at 5,000 miles, Delvac One 5w40, aka Mobil One Truck & SUV 5w40, aka Mobil One TDT 5w40, does not carry the VW 500.00 series rating. While I would recommended using oils with the VW ( du jour) approved ratings, this oil seems to perform in an almost stellar fashion. For the 2.0 and 1.8T I have heard of consumption up to 1 qt per 1,000 miles (and even less than 1,000 miles !!)

Replying to: shipo (Apr 13, 2009 7:59 am) The "needle in the haystack problems" remains however. So for another example, I could have selected the 2003 TDI with the O1M automatic transmission.......  Perhaps the outcome COULD have been FAR different on the transmission despite a GREAT TDI engine

The new Touareg TDI has hit the showrooms here in San Diego. The tax credit is only $1150. Better than nothing I guess. I like the looks of the Touareg best of the diesel SUVs on the market. The ML320 CDI is the most comfortable of the bunch. The BMW X5 & GL320 CDI get the biggest tax credit of $1800. The VW comes with leather in the base configuration and should be going for right about $40k before TTL and the tax credit.

Replying to: gagrice (Apr 23, 2009 1:54 pm) Not to get anyone's dander up, but  first look, it looks like a VW Jetta Sportwagon, albeit higher and bigger/chunkier. link title VW Sportwagon link title It will be interesting to see/hear how the 3.0 V6 TDI does. 221 hp/407 # ft and EPA of 17/25 mpg, it does set the bar/s very high, both for SUV's and INXS of 4,000 #'s segment vehicles. With a 26.4 gal tank, a 650+ miles range is nothing to sneeze at either. I am swagging after 10,000 miles initial break in, 26-30 mpg will not be difficult to achieve. Vs a TLC getting 14-16 mpg ( mid point of 15 mpg) , getting 25 mpg , I will take 67% better fuel mileage !!!!!!!!! To put it in perspective, Jetta TDI 2.0 I4 140 hp/236 # ft, EPA of 29/40 mpg. It is getting a range of 39-45 mpg. During the normal commute, (can't be herky jerky) more like 41-44 mpg. During a break in 2,300 miles trip/run (lots of spots to be herky jerky), it posted over all 43.5 mpg. (or so) Highway 5 N/S, S/N was actually in construction herky jerky, (more like perpetual , but another issue) so it was simple to blend in.  Vancouver's WA,BC were both BAD. Portland's and Seattle's downtown's traffic was a rolling parking lot- (I am being too optimistic here I know). All in all a great trip.
