Question Answered: engine runs rough(miss fires) at 2900RMP
January 21, 2009, 01:36 PM
If the misfire is ignition related you may have a crack or electrical fault in the ignition coil.
With the engine running spray the ignition coil and cables with a mist of salty water. This will "stress" these areas of the ignition system.
Any electrical leakage will become evident as an immediate misfire or visible electrical arcing.
If you have access to an appropriate scan tool you can confirm fuel mixture , if it is random multiple misfire fault or a specific cylinder misfiring.
The direction you take in repair starts with that information.

Question Answered: speedometer
January 21, 2009, 12:59 PM
Since your check engine light is not on and everything else that uses the speed sensor signal is ok you may well have a problem in the instrument cluster itself.
A good place to start would be to remove the instrument cluster and confirm all the connections at the cluster itself. Inspect the wiring and connectors as well as the physical attachments at the cluster.
If you have a wiring diagram and digital multimeter or scope you can confirm a steady signal at the cluster. You may have a failure at the instrument (speedometer) , or simply a poor connection.
The speedo signal can be monitored with a scan tool as well.
Often the act of disconnecting and reconnecting the instrument cluster will restore operation.....
Question Answered: Front luggage compartment

Look under the left fender , under the fender liner (black plastic) near/behind the spring. Their is a metal cable with a loop in it. Use a hook type tool to grab it and pull. Hood should release.
The cable is tucked away , but it's there.
You will need to remove the wheel and maybe pull back the liner to accomplish this. Not something done on the side of the road.....

If the immobilizer logo , it looks like a VW beetle , in the instrument cluster is flashing when the engine starts it is indeed an "alarm" issue.....
Question Answered: Oil Pressure Light
January 13, 2009, 12:33 AM
If you're confident the oil pressure at 2200 rpm is above 22 psi , at operating temperature , you either have a failing high pressure switch , the one located on the head , or a failing control unit in the instrument cluster.
Remove the electrical connector from the oil pressure switch and place a 12 volt test light between the switch and the battery positive post. The test light should be on. Start the engine , increase engine speed. The test light should go out at around 2200 rpm. If not , the SWITCH is bad. If it does go out you may well have a problem in the cluster.
As a footnote when the test light is on or off , it should not flicker. If it does The SWITCH is bad.
Question Answered: brake failiure
January 07, 2009, 12:18 PM
this can occur if there is water in the brake booster. drainage issues in the plenum area , usually caused by leaves blocking the drains , allows water to accumulate and enter the vacuum booster. freezing conditions obviously turn the water into ice , which will jam the booster/brakes internally. warmer temperatures thaw the ice relieving the blockage.
you need to replace the brake booster after confirming this diagnosis and repairing the root cause of the problem , water in the plenum.
Question Answered: My brakes are at 50% - what does this mean?
January 07, 2009, 12:06 PM
audi brake pads should be replaced when their is <4mm pad material remaining. there is a tool to measure the wear without pulling the wheels.
incidentally 4mm is the maximum thickness at which audi warranty will cover brake pad replacement
Question Answered: Blue Smoke
December 24, 2008, 12:29 PM
you need to read the fault code label associated with the check engine light.
blue smoke is usually indicative of oil burning.if your passat is the turbo you may have a turbo oiling issue.the turbo models also have issues with crankcase/intake plumbing problems.
no matter , you need to start with read the fault code .
Question Answered: window regulator

Your window regulator has failed in a very typical fashion.
Other than replacement window regulators are not repairable.Just specify which door it is for and whether it is manual or power windows.
Car Review: 2001 Volkswagen EuroVan
October 17, 2008, 02:47 PM
I've not actually owned a Eurovan but I've worked on them for years and years as a technician at the VW dealer.The majority of the issues are maintenance items such as brake pad and rotor replacement , some coolant leaks and occasional electrical issues including check engine lights. Nothing really dificult to resolve.
The owners love these cars for their utility , and space.I see them used for camping trips , day to day family "shuttle" and all around city vehicle.
They are large vehicles and most of the wear and tear is related to that.
Just my impressions as a non-owner......
Car Review: 2003 Volkswagen Beetle
October 08, 2008, 01:45 PM
I've enjoyed the beetle since new.Stylish in it's own way.It grows on you.Simple 2.0 Liter
engine runs and runs.
I wore out the clutch at 50,000 miles , replaced brakes now and than.
I drive hard , the car does well.
Car Review: 2001 Volkswagen Passat
October 08, 2008, 12:42 PM
Compared to the Audi A4 this a lot of car for the money.A few electrical problems...the flashers quit , door remote problem.The check engine light came on twice.Replaced coolant sensor and a spark plug wire to fix.Brakes have been replaced front and rear.
Mechanically other than maintenance I've done the axle boots.
Very comfortable around town and on the road.OK by me.
Car Review: 1993 Porsche 968
October 06, 2008, 02:22 PM
A real nice car.Easy to drive fast.No drama.Stick shift coupe was hard to find.Most are convertibles with automatic transmissions.A real classy ride.A little spendy to keep up at times , but not bad.
Red with Black leather interior is it.
Car Review: 2000 Audi TT
October 06, 2008, 02:11 PM
This has been a fun car.Not super fast , it handles well though.Maintenance cost are so-so.A few water leaks in the rain.All OK now.Had to fix a few things in the suspension....creaking noise.Brakes needed a few times as well.
Car Review: 2002 Audi Allroad Quattro
October 06, 2008, 02:02 PM
For the right owner these can be great cars.Not an SUV and not an avant this is the right mix of both.Somewhat high maintenance , a great performer and stylish.The proven Quattro four wheel drive system works well with the air suspension.A real joy is the V-8 with the manual transmission.Hard to find though.
Many very high mileage daily drivers on the road still.A sought after choice in the used car market attest to their popularity.
Car Review: 1990 Volkswagen Jetta
October 03, 2008, 02:07 PM
This has a pretty good bread and butter sort of car.Not exciting at all , but it runs and runs.Fairly comfortable , not a great performer , but easy enough to keep up.The interior shows its age , I put tires on it now and again.Biggest expense has been timing belt and water pump replacement.A/C went south awhole back but still a good daily driver.
Car Review: 1990 Porsche 911
October 03, 2008, 01:58 PM
A real success story for Porsche.The 911 line up seemed to get better with each year.This is the "real" Porsche design philosophy...rear engine , air cooled.A great performer , the engine is as strong as they come.Service cost can be high.For example valves require manual adjustment , dual ignition has twelve spark plugs...every 15,000 mile service.Plus twelve quarts of synthetic oil every 7,500 miles.Unfortunately deferred maintenance will cost in the long run.A few oil leaks remain to be fixed , but thats on the list.
All in all a real tour de force from concept to build.
Car Review: 1991 Porsche 928
October 03, 2008, 01:44 PM
A great car for around town or trips to L.A.Generally people love the styling , though some hate it!By contemporary standards this a real eye catcher.Anyhow , a bit of a chore to keep up with service needs.Engine is a great performer but tempermental at times.For a large car the handlig is great.If you like going fast , tire life can be disappointing.Very comfortable for two , climate control is fully up to the task.Sort of an overlooked gem in its time.They can be a great buy today.Buy the latest model you can , problems were resolved in the later years of production.A real joy to own.
Car Review: 1990 Porsche 944
October 03, 2008, 01:31 PM
As an affordable entry into owning a Porsche this has been a great car.Parts are pretty affordable ,a little tricky to work on.but basic stuff like brakes and oil change no problem ,if your set up.I am at 145,00 miles now , after nearly 80,000 of ownership.No real failures at all.Replaced timing belt twice as needed and replaced the water pump once.Brakes are really good , replaced pads & rotors awhile back , pad life more than reasonable.A good first , modern Porsche.
