There are MANY engine control malfunctions that can cause the engine control system to default to "Reduced Power Mode".
Reduced Power Mode is simply a computer strategy that was created by the vehicle manufacturers to keep people from doing dumb things like continuing to operate the vehicle with the "Check Engine" or other warning lamps YELLING at them to get their car properly diagnosed and repaired. Reduced Power Mode is also designed to protect the vehicle from further damage in certain cases.
Ignoring the warning lamps can cause safety issues as well as damage HIGH DOLLAR parts like catalytic converters, which the vehicle manufacturers are responsible for due to Federal Emissions and Safety laws.
As for whether it is covered under warranty....
Many major components of your engine control system are covered under the Federally-Mandated 8-Year 80,000 mile emissions warranty. The ONLY way to find out if your particular failure is covered is to have the vehicle first diagnosed to determine what is CAUSING the failure. Then you must check with an authorized dealer to see if the part (or parts) causing the problem are covered.

Hi It me Mohammad Siddiq my dear. First of all it will be wise of use to take your vehicle to a dealership or any other fully equipped w/shop. They can better tell you what the fault your vehicle has. But at the same time if your friend has the same model vehicle so you can exchange some parts with that vegicle, e.g., Mass Air Flow or TPS (Throttle Position Sensor) and can check your vehicle. These parts do not need to be programmed with scan tool. Just Simply replace these parts and switch on the ignition and wait for 01 minute, then switch off for 30 seconds and then start the engine. Now road test your vehicle, if no SES light or reduced power then there was fault with the part/s replaced. So Return those parts and now you must replace these parts with new or used ones. Anything else I may be contacted on my yahoo id [email protected]. Thanks. I am an auto technician and working in a GM dealership in Saudi Arabia. I am from Pakistan.

It's fuel related, check your fuel filter to see if it's clogged, let me know. Good luck, Jim

i would first pressure test the cooling system. 15psi and hold it for a few minutes. to make sure you didn't crack the cyl.head or block. also if you think it is just a faulty gauge you can get a temp. reading from the engine (by the thernostst housing) where the radiator hose comes out of the engine. 180 - 200 degress should be normal. it should be higher than the thermostat should allow.

Does this happen with a lot of the tdi's? Has anyone found a solution yet? Got the same problem with a 2000 tdi 90bhp stock 90000miles.
