SOURCE: BAD TURBO - REPLACEMENT COST?

I've seen quotes in the $1500-2500 range, depending on what needs to be done and what the parts prices are. Regardless, when you do it you may want to upgrade or at least replace the diverter valve (DV) as well - they have a plastic diaphragm inside and are prone to failure. You can buy a new OEM one, an aftermarket one such as a Forge DV, or upgrade to an OEM DV from an Audi TT 225.

If you're in the northeast, I can help you out with this - I can change it out in my garage and I happen to have a pair of OEM K03 turbos from a 2001 S4 sitting on my shelf:) If you are in this area, leave me an email address where I can contact you and I can arrange to help you out (at a significantly lower cost than those shop prices quoted above).

I know it sounds funny, but check the air flow sensor. They had issues on all models with 100 and 130 bhp turbocharged diesels from audi/volkswagen.

SOURCE: Windscreen wipers not working. Is this the motor

I had this problem two years ago on my Audi A4. First you must diagnose this problem. In order to find out the cause of wipers stopping you can try follows: 1. Carefully extract the wiper arms from their axles (two pieces). In some cases you need to use an extracting tool. Heed of the windscreen !!! 2. Disassemble the plastic covers from the bottom of the windscreen. 3. With the bonnet up you can start the engine, (transmission in "N" or "P" position and parking brake on). Now you must switch on the control lever of the wipers, and go to the engine compartment. If the wiper motor runs let the wiper motor running for a few minutes and switch off. Go to the step 4. If the wiper motor do not runs you must check first the electrical feeding of the motor. It is necessary to unscrew three bolts of the mechanism and disconnect the electrical coupling (difficult assurance). If the electrical feeding is OK you must replace the motor - steps 5, 6, 7. If not you must check electrical connections, the control switch of wipers and electric cables. 4. Now you must check the two bearings of wiper mechanism with your hand. In the most cases the left bearing is out of order (is very hot). This is the most encounter fault of the wipers running at Audi. 5. For have enough space to manipulation the wiper motor together with their mechanism you must extract the plastic cover of the engine computer box, and extract also the box screws. Then you can move slowly the engine computer box, just for a few milimeters. 6. You must disconnect the electrical coupling of the motor (difficult assurance), unscrew three bolts of the mechanism and extract together with the motor. You must move them slowly between windscreen and engine computer box until the wiper motor go out together with the mechanism. This is the most difficult operation! 7. Now you can repair the bearings, replace entire wiper mechanism or replace the wiper motor. It is not very simply, but it works. Heed of the windscreen !!! Refit in reverse order. Please Rate my Response! Thanks!

I have a 2000 audi a4 1.8t and seems to run sluggish over a 100kms, no engine light on, any possible reasons why?


If it runs well but is low on power it is possible that you are not getting any turbo boost. The wastegate actuator may be bad. The n75 valve that controls the actuator could be bad, also the N710 diverter vave may be bad.

Hi
More than just bad luck i suspect. Problem will almost surely be turbo overboost. Possible causes, wastegate jammed, actuator siezed, boost sensor inop. Best advice is to have fault codes and live data read with a suitable scan tool to determine the exact cause of the overboost condition. Easy enough job for competent garage.

What is a wastegate on 2004 dodge 5.9L cummins diesel?


The wastegate is a valve that regulates the ammount of boost that you turbocharger produces. The wastegate opens to release boost pressure.
This valve is electronicly controlled based on inputs to the onboard computer.

Need clutch replacement?


If you looking to change just the clutch it will cost you around $350 in parts and $500 in labor if you find right mechanic. There's also an option/recomended to change your flywheel as well which is also additional about $500. But this is the cheapest I know of. On my 1.8T previous owner ended up paying $2500 for clutch, flywheel and labor.

Boost(?) problem audi tt


It is probably either the N75 valve(Diverter Valve) or the wastegate actuator. Usually a significant boost leak will set a DTC, still check all hoses and clamps.

A bad wastegate actuator or flap would cause no boost but not necessarily the air-sound.

Testing N75

Air Bypass Valve: Testing and Inspection
With Generic Scan Tool
Wastegate Bypass Regulator Valve, Checking
Recommended special tools and equipment e.g.:
- VAG1526 multimeter or VAG1715 multimeter
- VAG1594 connector test kit
Test sequence
- Switch ignition off.
- Disconnect connector at solenoid valve for boost pressure regulation.
517f5c6.jpg - Measure resistance between terminals of valve.
Specified value: 25...35 Ohm
If specified value is not obtained:
- Replace Wastegate Bypass Regulator Valve -N75-.

Testing N249

Exhaust Bypass Valve: Testing and Inspection
With Generic Scan Tool
Recirculating Valve For Turbocharger, Checking
NOTE:
Valve opens between connection to intake manifold and connection to deceleration shut-off valve with no voltage. Connection to vacuum
reservoir is closed.
Test sequence
- Switch ignition off.
- Disconnect connector from Recirculating valve for turbocharger -N249-.

9dfbfb9.jpg - Measure resistance between terminals of valve.
Specified value: 27...30 Ohm
If specified value is not obtained:
- Replace Recirculating valve for turbocharger -N249-.
If specified values are obtained:
- Connect test box to control module wiring harness, connect test box for wiring test.

1a741bd.jpg - Check wire between test box socket 105+2-pin connector terminal 2 for open circuit according to wiring diagram.
Wire resistance: max: 1.5 Ohm
- Also check the wire for short circuit to B+ and Ground (GND).
If no malfunctions are found in wire:
- Check wire between 2-pin connector terminal 1 and the Fuel Pump (FP) Relay -J17- for open circuit according to wiring diagram.
Wire resistance: max: 1.5 Ohm
If no malfunctions are found in wires:
- Replace Engine Control Module (ECM).

____________________________________________


To test the wastegate, locate the wastegate linkage rod and verify that there is no play and that it is closed. You can apply compressed air to the actuator to see if it opens and closes. (not more than 30 psi)

02 Audi a4 losing power


You have blown a turbo charge pipe somewhere, check all hoses...Once this happens the car will begin to run very rich, as evidenced by the black smoke. Do not continue to drive like this, as the raw unburned fuel in the exhaust will clog the catalysts and that can be very expensive.
